-用过其它博客系统，不喜欢，不够轻，不够快！自己做过共两款博客系统，完美主义的我（毕竟处女座）也实在是不想再在这件事情上过多纠结了。`Eiblog`应该是一个比较稳定的博客系统，且是博主以后使用的博客系统，稳定性和维护你是不用担心的，唯独该系统部署过程太过复杂，并且不推荐没有计算机知识的朋友搭建，欢迎咨询。该博客的个中优点（明显快，安全），等你体验。
+用过其它博客系统，不喜欢，不够轻，不够快！自己做过共两款博客系统，完美主义的我（毕竟处女座）也实在是不想再在这件事情上过多纠结了。`Eiblog` 应该是一个比较稳定的博客系统，且是博主以后使用的博客系统，稳定性和维护你是不用担心的，唯独该系统部署过程太过复杂，并且不推荐没有计算机知识的朋友搭建，欢迎咨询。该博客的个中优点（明显快，安全），等你体验。

 <!--more-->

 ### 介绍
+
 整个博客系统涉及到模块如下：

+* 自动更新证书：
+  * 接入 [acme/autocert](https://github.com/golang/crypto/tree/master/acme/autocert)，在 TLS 层开启全自动更新证书，从此证书的更新再也不用惦记了，不过 Go 的 HTTPS 兼容性不够好（不想兼容），在如部分 IE 和 UC 之类的浏览器不能访问，请悉知。
+  * 如果你采用如 Nginx 代理，推荐使用 [acme.sh](https://github.com/Neilpang/acme.sh) 实现证书的自动部署。博主实现 aliyun dns 的自动验证方式，详见 [Makefile/gencert](https://github.com/eiblog/eiblog/blob/master/Makefile)。
 * `MongoDB`，博客采用 mongodb 作为存储数据库。
-* `Elasticsearch`，采用`elasticsearch`作为博客的站内搜索，尽管占用内存稍高。
+* `Elasticsearch`，采用 `elasticsearch` 作为博客的站内搜索，尽管占用内存稍高。
 * `Disqus`，作为博客评论系统，国内大部分被墙，故实现两种评论方式。
-* `Nginx`，作为反向代理服务器，并做相关`http header`和证书的设置。
+* `Nginx`，作为反向代理服务器，并做相关 `http header` 和证书的设置。
 * `Google Analytics`，作为博客系统的数据分析统计工具。
 * `七牛 CDN`，作为博客系统的静态文件存储，博文的图片附件什么上传至这里。

-相关技术有：
+### 图片展示

-* `Golang`，博客系统后端采用golang编写，并开源至[Eiblog](https://github.com/eiblog/eiblog)。
-* `HTML Javascript CSS`，博客系统的前端采用`html`和`jquery`编写，样式采用`CSS`。
-* `Glide`， golang 编写。作为博客系统的包依赖管理器，其开源地址是[Glide](https://github.com/Masterminds/glide)。
-* `Docker`，博客系统可 docker 部署，方便，快捷。
-* `Docker Compose`，博客系统可完全 docker 运行，compose起到很好管理作用。
-* `SSL 证书`，`https`是未来的趋势，整个博客系统都将围绕着`证书`进行，请事先准备好一张有效的 ssl 证书。
-* `Travis`，作为博客系统的自动构建工具，自动构建docker镜像并推送到镜像仓库。
-* `Yaml`，博客系统的配置文件使用`yaml`，请悉知。
-
-作为博主之心血之作，`Eiblog`实现了什么功能，有什么特点，做了什么优化呢？
-
-1. 系统目前只有`首页`、`专题`、`归档`、`友链`、`关于`、`搜索`界面。相信已经可以满足大部分用户的需求。
-2. `.js`、`.css`等静态文件本地存储，小图片 base64 内置到 css 中，不会产生网络所带来的延迟，加速网页访问。版本控制方式，动态更新静态文件。
-3. 采用谷歌统计，并实现异步（将访问信息发给后端，后端提交给谷歌）统计，加速访问速度。
-4. 采用直接缓存 markdown 转过的 html 文档的方式，加速后端处理。响应速度均在 3ms 以内，真正极速。
-5. 通过 Nginx 的配置，开启压缩缩小传输量，服务器传输证书链、开启`Session Resumption`、`Session Ticket`、`OCSP Stapling`等加速证书握手，再次提高速度。
-6. 文章评论数量（不重要）后端跑定时脚本，定时更新，所以有时评论数是不对的。这样减少了 api 调用，又再次达到加速访问的目的。
-7. 针对`disqus`被墙原因，实现[Jerry Qu](https://imququ.com)的另类评论方式，保证评论的流畅。
-8. 开源`Typecho`完整后台系统，全功能`markdown`编辑器，让你体验什么是简洁清爽。
-9. 博客后台直接对接`七牛 SDK`，实现后台上传文件和删除文件的简单功能。
-10. 采用`elasticsearch`作为站内搜索，添加`google opensearch`功能，搜索更加自然。
-
-当然，在信息安全方面也没少下功夫，虽然我们只是一个小小的博客系统。
-
-1. `CDN`，使用七牛融合CDN，并`https`化，实现全站`https`。七牛可申请免费证书了。
-2. `CT`，证书透明度检测，提供一个开放的审计和监控系统。可以让任何域名所有者或者 CA 确定证书是否被错误签发或者被恶意使用，从而提高 HTTPS 网站的安全性。
-3. `OSCP`，在线证书状态协议。用来检验证书合法性的在线查询服务.
-4. `HSTS`，强制客户端（如浏览器）使用 HTTPS 与服务器创建连接。可以很好的解决 HTTPS 降级攻击。
-5. `HPKP`，HTTP公钥固定扩展，防范由「伪造或不正当手段获得网站证书」造成的中间人攻击。该功能让我们选择信任哪些`CA`。
-5. `SSL Protocols`，罗列支持的`TLS`协议，SSLv3被证实是不安全的。
-6. `SSL dhparam`，迪菲赫尔曼密钥交换。
-7. `Cipher suite`，罗列服务器支持加密套件。
-
-可以容易的看到[httpsecurityreport](https://httpsecurityreport.com/?report=deepzz.com)评分`96`，[ssllabs](https://www.ssllabs.com/ssltest/analyze.html?d=deepzz.com&latest)评分`A+`，堪称完美。这些安全的相关配置会在后面的部署过程中接触到。

-好了，说了那么多，吹了那么多，我们实际来动手搭建一个`Eiblog`吧。
+### 极速体验
+1. 到 [这里](https://github.com/eiblog/eiblog/releases) 下载对应平台 `.tar.gz` 文件。

-### 安装
-1、`Eiblog`提供多个平台的压缩包下载，可到[Eiblog release](https://github.com/eiblog/eiblog/releases)选择相应版本和平台下载。也可通过：
-``` sh
-$ curl -L https://github.com/eiblog/eiblog/releases/download/v1.0.0/eiblog-v1.0.0.`uname -s | tr '[A-Z]' '[a-z]'`-amd64.tar.gz > eiblog-v1.0.0.`uname -s | tr '[A-Z]' '[a-z]'`-amd64.tar.gz
+2. 搭建 `MongoDB`（必须）和 `Elasticsearch`（可选）服务，正式部署需要。
+
+3. 修改 `/etc/hosts` 文件，添加 `MongoDB` 数据库 IP 地址，如：`127.0.0.1       mongodb`。
+
+4. 执行 `./eiblog`，运行博客系统。看到：
 ```
-
-2、如果有幸你也是`Gopher`，相信你会亲自动手，你可以通过：
-``` sh
-$ go get https://github.com/eiblog/eiblog
+...
+...
+[GIN-debug] Listening and serving HTTP on :9000
 ```
-进行源码编译二进制文件运行。
+代表运行成功了。

-3、如果你对`docker`技术也有研究的话，你也可以通过`docker`来安装：
-``` sh
-$ docker pull registry.cn-hangzhou.aliyuncs.com/deepzz/eiblog
+默认监听 `HTTP 9000` 端口，后台 `/admin/login`，默认账号密码均为 `deepzz`。更多详细请查阅 [安装部署](https://github.com/eiblog/eiblog/blob/master/docs/install.md) 文档。

-```
-镜像内部只提供了`eiblog`的二进制文件，因为其它内容定制化的需求过高。所以需要将`conf`、`static`、`views`目录映射出来，后面会具体说到。
+### 特色功能

-### 本地测试
-在我们下载好可执行程序之后，我们可以开始本地测试的工作了。
+作为博主之心血之作，`Eiblog` 实现了什么功能，有什么特点，做了什么优化呢？

-本地测试需要搭建两个服务`mongodb`和`elasticsearch2.4.1`（可选，搜索服务不可用）。
+1. 系统目前只有 `首页`、`专题`、`归档`、`友链`、`关于`、`搜索` 界面。相信已经可以满足大部分用户的需求。
+2. `.js`、`.css` 等静态文件本地存储，小图片 base64 内置到 css 中，不会产生网络所带来的延迟，加速网页访问。版本控制方式，动态更新静态文件。
+3. 采用谷歌统计，并实现异步（将访问信息发给后端，后端提交给谷歌）统计，加速访问速度。
+4. 采用直接缓存 markdown 转过的 html 文档的方式，加速后端处理。响应速度均在 3ms 以内，真正极速。
+5. 通过 Nginx 的配置，开启压缩缩小传输量，服务器传输证书链、开启 `Session Resumption`、`Session Ticket`、`OCSP Stapling `等加速证书握手，再次提高速度。
+  * `CDN`，使用七牛融合CDN，并 `https` 化，实现全站 `https`。七牛可申请免费证书了。
+  * `CT`，证书透明度检测，提供一个开放的审计和监控系统。可以让任何域名所有者或者 CA 确定证书是否被错误签发或者被恶意使用，从而提高 HTTPS 网站的安全性。
+  * `OSCP`，在线证书状态协议。用来检验证书合法性的在线查询服务.
+  * `HSTS`，强制客户端（如浏览器）使用 HTTPS 与服务器创建连接。可以很好的解决 HTTPS 降级攻击。
+  * `HPKP`，HTTP 公钥固定扩展，防范由「伪造或不正当手段获得网站证书」造成的中间人攻击。该功能让我们选择信任哪些`CA`。请不要轻易尝试 Nginx 线上运行，因为该配置目前只指定了 Letsencrypt X3 和 TrustAsia G5 证书 pin-sha256。
+  * `SSL Protocols`，罗列支持的 `TLS` 协议，SSLv3 被证实是不安全的。
+  * `SSL dhparam`，迪菲赫尔曼密钥交换。
+  * `Cipher suite`，罗列服务器支持加密套件。
+6. 文章评论数量（不重要）后端跑定时脚本，定时更新，所以有时评论数是不对的。这样减少了 api 调用，又再次达到加速访问的目的。
+7. 针对 `disqus` 被墙原因，实现 [Jerry Qu](https://imququ.com) 的另类评论方式，保证评论的流畅。
+8. 开源 `Typecho` 完整后台系统，全功能 `markdown` 编辑器，让你体验什么是简洁清爽。
+9. 博客后台直接对接 `七牛 SDK`，实现后台上传文件和删除文件的简单功能。
+10. 采用 `elasticsearch` 作为站内搜索，添加 `google opensearch` 功能，搜索更加自然。

-`Eiblog`默认会连接`hostname`为`eidb`和`eisearch`，因此你需要将信息填入`/etc/hosts`下。假如你搭建的`mongodb`地址为`127.0.0.1:27017`，`elasticsearch`地址为`192.168.99.100:9200`，如：
-``` sh
-$ sudo vi /etc/hosts
-
-# 在末尾加上两行
-127.0.0.1       eidb
-192.168.99.100  eisearch
-```
-
-#### MongoDB 搭建
-1、`MongoDB`搭建，Mac 可通过`brew install mongo`进行安装，其它平台请查询资料。
-#### Elasticsearch 搭建
-2、`Elasticsearch`搭建，它的搭建要些许复杂。博主尚未接触如何直接安装，因此建议通过`docker`搭建。需要注意的是 es 自带的分析器对中文分词是不友好的，这里采用了`elasticsearch-analysis-ik`分词器。如果你想了解更多[Github](https://github.com/medcl/elasticsearch-analysis-ik)或则如何实现[博客站内搜索](https://imququ.com/post/elasticsearch.html)。
-
-* pull 镜像`docker pull elasticsearch:2.4.1`，必需使用该版本。
-* 添加环境变量`ES_JAVA_OPTS: "-Xms512m -Xmx512m"`，除非你想让你的服务器爆掉。
-* 映射相关目录：
-
-  ```
-  conf/es/config:/usr/share/elasticsearch/config
-  conf/es/plugins:/usr/share/elasticsearch/plugins
-  conf/es/data:/usr/share/elasticsearch/data
-  conf/es/logs:/usr/share/elasticsearch/logs
-  ```
-  请将这四个目录映射至`eiblog`下的`conf`目录。如果你想查看更多，请查看`docker-compose.yml`文件。
-
-总结一下，`docker`运行 es 的命令为：
-``` sh
-$ docker run -d --name eisearch \
-    -p 9200:9200 \
-    -e ES_JAVA_OPTS: "-Xms512m -Xmx512m" \
-    -v conf/es/config:/usr/share/elasticsearch/config \
-    -v conf/es/plugins:/usr/share/elasticsearch/plugins \
-    -v conf/es/data:/usr/share/elasticsearch/data \
-    -v conf/es/logs:/usr/share/elasticsearch/logs \
-    elasticsearch:2.4.1
-```
-
-之后执行`./eiblog`，咱们的`eiblog`就可以运行起来了。
-
-通过`127.0.0.1:9000`可以进入博客首页，`127.0.0.1:9000/admin/login`进入后台登陆，账号密码为`eiblog/conf/app.yml`下的`username`和`password`。也就是初始账号密码`deepz`、`deepzz`。
-
-> `注意`，因为配置`conf/app.yml`均是博主自用配置。有些操作可能（如评论）会评论到我的博客，还请尽量避免，谢谢。
-
-### 准备部署
-如果你在感受了该博客的魅力了之后，仍然坚持想要搭建它。那么，恭喜你，获得的一款不想再更换的博客系统。下面，我们跟随步骤对部署流程进一步说明。
-
-这里只提供`Docker`的相关部署说明。你如果需要其它方式部署，请参考该方式。
-
-#### 前提准备
-这里需要准备一些必要的东西，如果你已准备好。请跳过。
-
-* `一台服务器`。
-* `一个域名`，国内服务器需备案。
-* `有效的证书`。一般使用免费的就可以。如：`Let‘s Encrypt`，另外`qcloud`、`七牛`也提供了免费证书的申请，均是全球可信。
-* `七牛CDN`。博客只设计接入了七牛cdn，相信该CDN服务商不会让你失望。
-* `Disqus`。作为博客评论系统，你得有翻墙的能力注册到该账号，具体配置我想又可以写一片博客了。简单说需要`shorname`和`public key`。
-* `Google Analystic`。数据统计分析工具。
-* `Superfeedr`。加速 RSS 订阅。
-* `Twitter`。希望你能够有一个twitter账号。
-
-是不是这么多要求，很费解。其实当初该博客系统只是为个人而设计的，是自己心中想要的那一款。博主些这篇文章不是想要多少人来用该博客，而是希望对那些追求至极的朋友说：你需要这款博客系统。
-#### 文件准备
-尽管大多数文件已经准备好。但有些默认的文件需要特别指出来，需要你在 CDN 上写特殊的路径。
-
-假如你的 CDN 域名为`st.example.com`，那么：
-
-* `favicon.ico`，其 URL 应该是`st.example.com/static/img/favicon.ico`。故你在 CDN 中的文件名为`static/img/favicon.ico`，以下如是。
-* `左侧背景图片`，`500*1200`左右，CDN 中文件名：`static/img/bg04.jpg`。如需更改，请在`eiblog/view/st_blog.css`中替换该名称。
-* `头像`，`160*160~256*256`之间，CDN 文件名：`static/img/avatar.jpg`。另外你需要将该图片 `Base64` 编码后替换掉`eiblog/views/st_blog.css`中合适位置的图片。
-* `blank.gif`，CDN 文件名：`static/img/blank.gif`。该图片请从[这里](https://st.deepzz.com/static/img/blank.gif)下载并上传至你的 CDN。
-* `default_avatar.png`，CDN 文件名：`static/img/default_avatar.png`，请从[这里](https://st.deepzz.com/static/img/default_avatar.png)下载并上传至你的 CDN。
-* `disqus.js`，该文件名是会变的，每次更新如果没有提及就没有改变，更新说明在[这里](https://github.com/eiblog/eiblog/blob/master/CHANGELOG.md)。CDN 文件名格式是：`static/js/name.js`。在我写这篇文章是使用的是：`static/js/disqus_a9d3fd.js`，请从[这里](https://st.deepzz.com/static/js/disqus_a9d3fd.js)下载并上传至你的 CDN。
-
-> `注意`：本人 CDN 做了防盗链处理，故请将这些资源上传至您的 CDN ，以免静态资源不能访问，请悉知。
-
-#### 配置说明
-走到这里，我相信只走到`60%`的路程。放弃还来得及。
-
-这里会对`eiblog/conf`下的所有文件做说明，希望你做好准备。

-1、app.yml，整个程序的配置文件，里面已经列出了所有配置项的说明，这里不再阐述。  
-2、blackip.yml，如果没有使用`Nginx`，博客内置`ip`过滤系统。  
-3、`es`全名`elasticsearch`，非常强大的分布式搜索引擎，`github`用的就是它。里面的配置基本不用修改，但`es/analysis/synonym.txt`是同义词，你可以照着已有的随意增加。
-```

-
-> `注意`，scripts文件夹虽然是空的，但必需存在，不然elasticsearch报错。
-
-4、`nginx`，系统采用`nginx`作为代理(相信博客系统也不会独占一台服务器～)。请使用`nginx.conf`替换原`nginx`的配置。博客系统的配置文件是`domain/deepzz.conf`，或则重命名(只要是满足`*.conf`)。`deepzz.conf`文件里面学问是最多的。或许你想一一弄懂，或许…。
-
-> 注意本配置需要更新nginx到最新版，openssl更新到1.0.2j，具体请到 Jerry Qu 的[本博客 Nginx 配置之完整篇](https://imququ.com/post/my-nginx-conf.html)查看，了解详情。
-
-5、`scts`，存放 ct 文件。
-
-6、`ssl`，这里存放了所有证书相关的内容。
-```
-├── dhparams.pem                #参见eiblog/conf/nginx/domain/deepzz.conf
-├── domain.key                  #证书私钥，一般颁发者处下载
-├── domain.pem                  #证书链，一般从证书颁发者那可以直接下载到
-├── full_chained.pem            #参见eiblog/conf/nginx/domain/deepzz.conf
-└── session_ticket.key          #参见eiblog/conf/nginx/domain/deepzz.conf
-```
-
-7、`tpl`模版相关，不用修改。
-
-### 开始部署
-
-#### docker
-请确定你已经完成了上面所说的所有步骤，在本地已经测试成功。服务器上`MognoDB`和`Elasticsearch`已经安装并已经运行成功。
-
-首先，请将本地测试好的`conf`，`static`，`views`文件夹上传至服务器，建议存储到服务器`/data/eiblog`下。
-``` sh
-$ tree /data/eiblog -L 1
-
-├── conf
-├── static
-├── views
-```
-
-然后，将镜像 PULL 到服务器本地。
-``` sh
-# PULL下Eiblog镜像
-$ docker pull registry.cn-hangzhou.aliyuncs.com/deepzz/eiblog
-```
-
-最后，执行`docker run`命令，希望你能成功。
-``` sh
-$ docker run -d --name eiblog --restart=always \
-    --add-host disqus.com:23.235.33.134 \
-    --link eidb --link eisearch \
-    -p 9000:9000 \
-    -e GODEBUG=netdns=cgo \
-    -v /data/eiblog/logdata:/eiblog/logdata \
-    -v /data/eiblog/conf:/eiblog/conf \
-    -v /data/eiblog/static:/eiblog/static \
-    -v /data/eiblog/views:/eiblog/views \
-    registry.cn-hangzhou.aliyuncs.com/deepzz/eiblog
-```
-这里默认`MongDB`和`Elasticsearch`均为`docker`部署，且名称为`eidb`，`eisearch`。
-
-#### nginx + docker
-通过`Nginx+docker`部署，是博主推荐的方式。这里采用`Docker Compose`管理我们整个博客系统。
-
-请确认你已经成功安装好`Nginx`、`docker`、`docker-compose`。Nginx 请一定参照 Jerry Qu 的[Nginx 配置完整篇](https://imququ.com/post/my-nginx-conf.html)。
-
-首先，请将本地测试好的`conf`，`static`，`views`，`docker-compose.yml`文件夹和文件上传至服务器。前三个文件夹建议存储到服务器`/data/eiblog`下，`docker-compose.yml`存放在你使用方便的地方。
-
-> 注意`conf/es/config/scripts`空文件夹是否存在
-
-``` sh
-$ tree /data/eiblog -L 1
-
-├── conf
-├── static
-├── views
-
-$ ls ~/
-
-docker-compose.yml
-```
-
-然后，执行：
-``` sh
-$ cd ~
-$ docker-compose up -d
-```
-
-等待些许时间，成功运行。

+### 证书自动更新
+
+本博客证书自动更新有两种方式：
+
+* [acme/autocert](https://github.com/golang/crypto/tree/master/acme/autocert)，博客内部集成，通过 tls-sni 验证，实现全自动更新证书，一键开启关闭。请在裸服务器的情况下使用（不要使用代理）。单证书
+* [acme.sh](https://github.com/Neilpang/acme.sh)，强大的 acme 脚本，多种自动更新证书方式，满足你各方面的需求。双证书
+
+#### 方式一
+什么是 autocert，简单点，你只需要两步操作：
+
+1. 将域名解析到你的服务器。
+2. 在服务器上运行开启 autocert 功能的程序（这里不需要配置证书），需要占用 443 端口。
+
+其它过程你不需要过问，即会完成自动申请证书，自动更新证书的功能（默认 30 天）。这个是在 tcp/ip 层的操作，对用户完全透明，非常棒。
+
+一键开启 autocert 功能，只需修改 `conf/app.yml` 文件内容：
+
+```
+# 运行模式
+mode:
+  # http server
+  enablehttp: true
+  httpport: 9000
+  # https server
+  enablehttps: true                     # 必须开启
+  autocert: false                       # autocert 功能开关
+  httpsport: 9001
+  certfile: 
+  keyfile: 
+  domain: deepzz.com                    # 申请证书的域名，也是博客的域名
+```
+
+首先，使用 HTTPS 必须启用  `enablehttps`，它有两个作用：
+
+* 如果 `enablehttp` 开启，会自动 301 重定向到 https。
+* 作为开启 autocert 的前提条件。
+
+其次， `autocert` 是否开启也有两个作用：
+
+* false，服务器将使用 `httpsport`、`certfile`、`keyfile` 作为参数启动 https 服务器。
+* true，服务器直接使用 443 端口启动 https 服务器，并且自动申请证书，且在证书只有 30 天有效期时自动更新证书。域名为 *运行模式* 下的 mode->domain。
+
+#### 方式二
+
+使用方式二，你需要了解 acme.sh 的具体使用方式，非常简单。选择适合自己的方式实现自动更新证书。
+
+博主，这里实现了 aliyun dns 的自动验证，自动更新证书。详情参见 Makefile->gencert。这里实现了自动申请 ecc、rsa 双证书，并且自动申请 scts，自动安装，自动更新。
+
+基本流程如下：
+
+1. 创建相关目录：`/data/eiblog/conf/ssl`、`/data/eiblog/conf/scts/rsa`、`/data/eiblog/conf/scts/ecc`。
+2. 自动下载安装 acme.sh 脚本。
+3. 自动申请 RSA 证书并且自动获取 scts，并且自动安装到指定位置。
+4. 自动申请 ECC 证书并且自动获取 scts，并且自动安装到指定位置。
+
+##### 使用方式
+
+导出环境变量，Aliyun dns 的环境变量为：
+
+```
+export Ali_Key="sdfsdfsdfljlbjkljlkjsdfoiwje"
+export Ali_Secret="jlsdflanljkljlfdsaklkjflsa"
+```
+
+执行命令：
+
+```
+$ make gencert -cn=common_name -sans="-d example.com  -d example1.com"
+```

+### 安装
+1、`Eiblog` 提供多个平台的压缩包下载，可到 [Eiblog release](https://github.com/eiblog/eiblog/releases) 选择相应版本和平台下载。也可通过：
+``` sh
+$ curl -L https://github.com/eiblog/eiblog/releases/download/v1.0.0/eiblog-v1.0.0.`uname -s | tr '[A-Z]' '[a-z]'`-amd64.tar.gz > eiblog-v1.0.0.`uname -s | tr '[A-Z]' '[a-z]'`-amd64.tar.gz
+```
+
+2、如果有幸你也是 `Gopher`，相信你会亲自动手，你可以通过：
+``` sh
+$ git clone https://github.com/eiblog/eiblog.git
+```
+进行源码编译二进制文件运行。
+
+3、如果你对 `docker` 技术也有研究的话，你也可以通过 `docker` 来安装：
+``` sh
+$ docker pull registry.cn-hangzhou.aliyuncs.com/deepzz/eiblog:v1.2.0
+```
+`注意`，镜像内部没有提供 conf 文件夹内的配置内容，因为该内容定制化的需求过高。所以需要将 `conf` 目录映射出来，后面会具体说到。
+
+### 本地测试
+采用二进制包进行测试，在下载好可执行程序之后，我们可以开始本地测试的工作了。本地测试需要搭建两个服务 `mongodb` （必须）和 `elasticsearch2.4.1`（可选，搜索服务不可用）。
+
+`Eiblog ` 默认会连接 `hostname` 为 `mongodb` 和 `elasticsearch` 的地址，因此你需要将信息填入 `/etc/hosts` 下。假如你搭建的 `mongodb` 地址为 `127.0.0.1:27017`，`elasticsearch` 地址为 `192.168.99.100:9200`，如：
+``` sh
+$ sudo vi /etc/hosts
+
+# 在末尾加上两行
+172.42.0.1      mongodb
+192.168.99.100  elasticsearch
+```
+
+下面先看两个服务的搭建。
+
+#### MongoDB 搭建
+
+`MongoDB` 搭建，Mac 可通过 `brew install mongo` 进行安装，其它平台请查询资料。
+#### Elasticsearch 搭建
+`Elasticsearch `搭建，它的搭建要些许复杂。建议通过 `docker` 搭建。需要注意的是 es 自带的分析器对中文分词是不友好的，这里采用了 `elasticsearch-analysis-ik` 分词器。如果你想了解更多 [Github](https://github.com/medcl/elasticsearch-analysis-ik) 或则如何实现 [博客站内搜索](https://imququ.com/post/elasticsearch.html)。
+
+1. pull 镜像  `docker pull elasticsearch:2.4.1`。
+
+2. 添加环境变量 `ES_JAVA_OPTS: "-Xms512m -Xmx512m"`，除非你想让你的服务器爆掉。
+
+3. 映射相关目录：
+
+   ```
+   $PWD/conf/es/config:/usr/share/elasticsearch/config
+   $PWD/conf/es/plugins:/usr/share/elasticsearch/plugins
+   ```
+
+博主已经准备好了必要的 es 配置文件，请将这四个目录映射至 `eiblog` 下的 `conf` 目录。如果你想查看更多，请查看 `docker-compose.yml` 文件。
+
+总结一下，`docker` 运行 es 的命令为：
+``` sh
+$ docker run -d --name eisearch \
+    -p 9200:9200 \
+    -e ES_JAVA_OPTS="-Xms512m -Xmx512m" \
+    -v $PWD/conf/es/config:/usr/share/elasticsearch/config \
+    -v $PWD/conf/es/plugins:/usr/share/elasticsearch/plugins \
+    elasticsearch:2.4.1
+```
+
+之后执行 `./eiblog`，咱们的 `eiblog` 就可以运行起来了。
+
+通过 `127.0.0.1:9000` 可以进入博客首页，`127.0.0.1:9000/admin/login` 进入后台登陆，账号密码为 `eiblog/conf/app.yml` 下的 `username` 和 `password`。初始账号密码 `deepz`、`deepzz`。
+
+> `注意`，因为配置 `conf/app.yml` 均是博主自用配置。有些操作可能（如评论）会评论到我的博客，还请尽量避免，谢谢。
+
+### 准备部署
+如果你在感受了该博客的魅力了之后，仍然坚持想要搭建它。那么，恭喜你，获得的一款不想再更换的博客系统。下面，我们跟随步骤对部署流程进一步说明。
+
+这里只提供 `Docker` 的相关部署说明。你如果需要其它方式部署，请参考该方式。
+
+#### 前提准备
+这里需要准备一些必要的东西，如果你已准备好。请跳过。
+
+* `一台服务器`。
+* `一个域名`，国内服务器需备案。
+* `有效的证书`。通过开启 autocert 可自动申请更新证书。也可去七牛、qcloud 申请一年有效证书。
+* `七牛CDN`。博客只设计接入了 七牛cdn，相信该 CDN 服务商不会让你失望。
+* `Disqus`。作为博客评论系统，你得有翻墙的能力注册到该账号，具体配置我想又可以写一片博客了。简单说需要 `shorname` 和 `public key`。
+* `Google Analystic`。数据统计分析工具。
+* `Superfeedr`。加速 RSS 订阅。
+* `Twitter`。希望你能够有一个 twitter 账号。
+
+是不是这么多要求，很费解。其实当初该博客系统只是为个人而设计的，是自己心中想要的那一款。博主些这篇文章不是想要多少人来用该博客，而是希望对那些追求至极的朋友说：你需要这款博客系统。
+#### 文件准备
+博主是一个有强迫症的人，一些文件的路径我使用了固定的路径，请大家见谅。假如你的 cdn 域名为 `st.example.com`，你需要确定这些文件已经在你的 cdn 中，它们路径分别是：
+
+| 文件                 | 地址                                       | 描述                                       |
+| ------------------ | ---------------------------------------- | ---------------------------------------- |
+| favicon.ico        | st.example.com/static/img/favicon.ico    | cdn 中的文件名为 `static/img/favicon.ico`。你也可以复制 favicon.ico 到 static 文件夹下，通过 example.com/favicon.ico 也是能够访问到。docker 用户可能需要重新打包镜像。 |
+| bg04.jpg           | st.example.com/static/img/bg04.jpg       | 首页左侧的大背景图，需要更名请到 views/st_blog.css 修改。   |
+| avatar.jpg         | st.example.com/static/img/avatar.jpg     | 头像                                       |
+| blank.gif          | st.example.com/static/img/blank.gif      | 空白图片，[下载](https://st.deepzz.com/static/img/blank.gif) |
+| default_avatar.png | st.example.com/static/img/default_avatar.png | disqus 默认图片，[下载](https://st.deepzz.com/static/img/default_avatar.png) |
+| disqus.js          | st.example.com/static/js/disqus_xxx.js   | disqus 文件，你可以通过 https://short_name.disqus.com/embed.js 下载你的专属文件，并上传到七牛。更新配置文件 app.yml。 |
+
+> 注意，cdn 提到的文件下载，请复制链接进行下载，因为博主使用了防盗链功能，还有：  
+  1、每次修改 app.yml 文件（如：更换 cdn 域名或更新头像），如果你不知道是否应该提高 staticversion 一个版本，那么最好提高一个 +1。  
+  2、每次手动修改 views 内的以 `st_` 开头的文件，请将 `app.yml` 中的 staticversion 提高一个版本。
+
+#### 配置说明
+走到这里，我相信只走到 `60%` 的路程。放弃还来得及。
+
+这里会对 `eiblog/conf` 下的所有文件做说明，希望你做好准备。

+| nginx       | 系统采用 `nginx` 作为代理(相信博客系统也不会独占一台服务器～)。请使用 `nginx.conf` 替换原 `nginx` 的配置。博客系统的配置文件是 `domain/eiblog.conf`，或则重命名(只要是满足`*.conf`)。`eiblog.conf`文件里面学问是最多的。或许你想一一弄懂，或许…。注意本配置需要更新 nginx 到最新版，openssl 更新到1.0.2j，具体请到 Jerry Qu 的 [本博客 Nginx 配置之完整篇](https://imququ.com/post/my-nginx-conf.html) 查看，了解详情。 |
+| scts        | 存放 ct 文件。                                |
+| ssl         | 这里存放了所有证书相关的内容。                          |
+| tpl         | 模版相关，不用修改。                               |
+
+### 开始部署
+
+#### docker
+请确定你已经完成了上面所说的所有步骤，在本地已经测试成功。服务器上 `MognoDB` 和`Elasticsearch` 已经安装并已经运行成功。
+
+首先，请将本地测试好的 `conf` 文件夹上传至服务器，建议存储到服务器 `/data/eiblog` 下。
+``` sh
+$ tree /data/eiblog -L 1
+
+├── conf
+```
+
+然后，将镜像 PULL 到服务器本地。
+``` sh
+# PULL下Eiblog镜像
+$ docker pull registry.cn-hangzhou.aliyuncs.com/deepzz/eiblog
+```
+
+最后，执行 `docker run` 命令，希望你能成功。
+``` sh
+$ docker run -d --name eiblog --restart=always \
+    --add-host disqus.com:23.235.33.134 \
+    --add-host mongodb:172.42.0.1 \
+    --add-host elasticsearch:192.168.99.100 \
+    -p 9000:9000 \
+    -e GODEBUG=netdns=cgo \
+    -v /data/eiblog/logdata:/eiblog/logdata \
+    -v /data/eiblog/conf:/eiblog/conf \
+    registry.cn-hangzhou.aliyuncs.com/deepzz/eiblog
+```
+这里默认 `MongDB` 和 `Elasticsearch` 均为 `docker` 部署，且名称为`eidb`，`eisearch`。
+
+#### nginx + docker
+通过 `Nginx+docker` 部署，是博主推荐的方式。这里采用 `Docker Compose` 管理我们整个博客系统。
+
+请确认你已经成功安装好 `Nginx`、`docker`、`docker-compose`。Nginx 请一定参照 Jerry Qu 的[Nginx 配置完整篇](https://imququ.com/post/my-nginx-conf.html)。
+
+首先，请将本地测试好的 `conf`，`docker-compose.yml` 文件夹和文件上传至服务器。`conf` 建议存储到服务器 `/data/eiblog` 下，`docker-compose.yml` 存放在你使用方便的地方。
+
+``` sh
+$ tree /data/eiblog -L 1
+
+├── conf
+
+$ ls ~/
+
+docker-compose.yml
+```
+
+然后，执行：
+``` sh
+$ cd ~
+$ docker-compose up -d
+```
+
+等待些许时间，成功运行。

+### 郑重提醒
+**标题**、**slug**、**内容**。在你点击保存的时候一定确保三者不能为空，否则页面刷新内容就没了。所以，养成一个良好的写作习惯很重要。
+
+当然，博客的自动保存功能也非常的好。在你不确定是否发布前，你可以将之保存到草稿，以便下次继续编辑。
+
+### 文章标题
+文章标题，这个可能要看个人习惯。我习惯从三级标题开始（###），依次往下四级标题，五级标题...。要注意的是一定不能跳级：
+```
+### 标题一
+
+#### 标题1.1
+#### 标题1.2
+##### 标题1.2.1
+##### 标题1.2.2
+
+### 标题二
+
+##### 标题2.1
+
+##### 标题2.2
+###### 标题2.2.1
+###### 标题2.2.2
+```
+
+结果是：
+![article-title](http://7xokm2.com1.z0.glb.clouddn.com/article-title.png)
+
+### 文章描述
+文章描述，主要是给`html->head->meta`中的 name 为 description 用的。现采用了一个临时的办法：在文章的第一行通过前缀识别（只看第一行）。
+
+该前缀可到`conf/app.yml`设置，默认为`Desc:`，如：
+
+![article-description](http://7xokm2.com1.z0.glb.clouddn.com/img/article-description.png)
+
+### 图片懒加载
+博客系统提供图片懒加载功能（浏览到某个位置，图片才会加载），以此来提高页面加载速度。我们可根据需要是否使用。
+
+当然由此带来的坏处就是rss不能够正确加载图片。后续看是否解决这个问题或朋友提PR。
+
+首先看下图片的`markdown`标准写法：
+```
+![alt](img_addres)
+```
+如：
+```
+![sublime-dialog](https://st.deepzz.com/blog/img/dialog-box-without-all-contols.png)
+```
+![sublime-dialog](https://st.deepzz.com/blog/img/dialog-box-without-all-contols.png)
+
+懒加载，需要为该图片指定大小（长高）：
+```
+![alt](img_addres =widthxheight)
+```
+
+x 为小写字母（x,y,z）中的 x。使页面未加载时也占了相应的位置大小，这样设计是为了让读者在浏览页面时不会感到抖动。
+
+如：
+```
+![sublime-dialog](https://st.deepzz.com/blog/img/dialog-box-without-all-contols.png =640x301)
+```
+
+### 摘要截取
+摘要截取主要是提供给首页显示，如：
+![home-page](http://7xokm2.com1.z0.glb.clouddn.com/img/deepzz_home_page.jpg)
+
+红框中圈出来的就是截取出来的内容。在 `conf/app.yml` 的配置项有两个：
+```
+# 自动截取预览, 字符数
+length: 400
+# 截取预览标识
+identifier: <!--more-->
+
+```
+当程序不能检查到 identifier 的标识符时，会采用长度的方式进行截取。

+[![Build Status](https://drone.io/github.com/boj/redistore/status.png)](https://drone.io/github.com/boj/redistore/latest)
+
+A session store backend for [gorilla/sessions](http://www.gorillatoolkit.org/pkg/sessions) - [src](https://github.com/gorilla/sessions).
+
+## Requirements
+
+Depends on the [Redigo](https://github.com/garyburd/redigo) Redis library.
+
+## Installation
+
+    go get gopkg.in/boj/redistore.v1
+
+## Documentation
+
+Available on [godoc.org](http://www.godoc.org/gopkg.in/boj/redistore.v1).
+
+See http://www.gorillatoolkit.org/pkg/sessions for full documentation on underlying interface.
+
+### Example
+``` go
+// Fetch new store.
+store, err := NewRediStore(10, "tcp", ":6379", "", []byte("secret-key"))
+if err != nil {
+	panic(err)
+}
+defer store.Close()
+
+// Get a session.
+session, err = store.Get(req, "session-key")
+if err != nil {
+	log.Error(err.Error())
+}
+
+// Add a value.
+session.Values["foo"] = "bar"
+
+// Save.
+if err = sessions.Save(req, rsp); err != nil {
+	t.Fatalf("Error saving session: %v", err)
+}
+
+// Delete session.
+session.Options.MaxAge = -1
+if err = sessions.Save(req, rsp); err != nil {
+	t.Fatalf("Error saving session: %v", err)
+}
+
+// Change session storage configuration for MaxAge = 10 days.
+store.SetMaxAge(10 * 24 * 3600)

+[![Build Status](https://travis-ci.org/davecgh/go-spew.png?branch=master)]
+(https://travis-ci.org/davecgh/go-spew) [![Coverage Status]
+(https://coveralls.io/repos/davecgh/go-spew/badge.png?branch=master)]
+(https://coveralls.io/r/davecgh/go-spew?branch=master)
+
+Go-spew implements a deep pretty printer for Go data structures to aid in
+debugging.  A comprehensive suite of tests with 100% test coverage is provided
+to ensure proper functionality.  See `test_coverage.txt` for the gocov coverage
+report.  Go-spew is licensed under the liberal ISC license, so it may be used in
+open source or commercial projects.
+
+If you're interested in reading about how this package came to life and some
+of the challenges involved in providing a deep pretty printer, there is a blog
+post about it
+[here](https://blog.cyphertite.com/go-spew-a-journey-into-dumping-go-data-structures/).
+
+## Documentation
+
+[![GoDoc](https://godoc.org/github.com/davecgh/go-spew/spew?status.png)]
+(http://godoc.org/github.com/davecgh/go-spew/spew)
+
+Full `go doc` style documentation for the project can be viewed online without
+installing this package by using the excellent GoDoc site here:
+http://godoc.org/github.com/davecgh/go-spew/spew
+
+You can also view the documentation locally once the package is installed with
+the `godoc` tool by running `godoc -http=":6060"` and pointing your browser to
+http://localhost:6060/pkg/github.com/davecgh/go-spew/spew
+
+## Installation
+
+```bash
+$ go get -u github.com/davecgh/go-spew/spew
+```
+
+## Quick Start
+
+Add this import line to the file you're working in:
+
+```Go
+import "github.com/davecgh/go-spew/spew"
+```
+
+To dump a variable with full newlines, indentation, type, and pointer
+information use Dump, Fdump, or Sdump:
+
+```Go
+spew.Dump(myVar1, myVar2, ...)
+spew.Fdump(someWriter, myVar1, myVar2, ...)
+str := spew.Sdump(myVar1, myVar2, ...)
+```
+
+Alternatively, if you would prefer to use format strings with a compacted inline
+printing style, use the convenience wrappers Printf, Fprintf, etc with %v (most
+compact), %+v (adds pointer addresses), %#v (adds types), or %#+v (adds types
+and pointer addresses): 
+
+```Go
+spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+```
+

+Here is an example of how you can use `spew.Sdump()` to help debug a web application. Please be sure to wrap your output using the `html.EscapeString()` function for safety reasons. You should also only use this debugging technique in a development environment, never in production.
+
+```Go
+package main
+
+import (
+    "fmt"
+    "html"
+    "net/http"
+
+    "github.com/davecgh/go-spew/spew"
+)
+
+func handler(w http.ResponseWriter, r *http.Request) {
+    w.Header().Set("Content-Type", "text/html")
+    fmt.Fprintf(w, "Hi there, %s!", r.URL.Path[1:])
+    fmt.Fprintf(w, "<!--\n" + html.EscapeString(spew.Sdump(w)) + "\n-->")
+}
+
+func main() {
+    http.HandleFunc("/", handler)
+    http.ListenAndServe(":8080", nil)
+}
+```
+
+## Sample Dump Output
+
+```
+(main.Foo) {
+ unexportedField: (*main.Bar)(0xf84002e210)({
+  flag: (main.Flag) flagTwo,
+  data: (uintptr) <nil>
+ }),
+ ExportedField: (map[interface {}]interface {}) {
+  (string) "one": (bool) true
+ }
+}
+([]uint8) {
+ 00000000  11 12 13 14 15 16 17 18  19 1a 1b 1c 1d 1e 1f 20  |............... |
+ 00000010  21 22 23 24 25 26 27 28  29 2a 2b 2c 2d 2e 2f 30  |!"#$%&'()*+,-./0|
+ 00000020  31 32                                             |12|
+}
+```
+
+## Sample Formatter Output
+
+Double pointer to a uint8:
+```
+	  %v: <**>5
+	 %+v: <**>(0xf8400420d0->0xf8400420c8)5
+	 %#v: (**uint8)5
+	%#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
+```
+
+Pointer to circular struct with a uint8 field and a pointer to itself:
+```
+	  %v: <*>{1 <*><shown>}
+	 %+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)<shown>}
+	 %#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)<shown>}
+	%#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)<shown>}
+```
+
+## Configuration Options
+
+Configuration of spew is handled by fields in the ConfigState type. For
+convenience, all of the top-level functions use a global state available via the
+spew.Config global.
+
+It is also possible to create a ConfigState instance that provides methods
+equivalent to the top-level functions. This allows concurrent configuration
+options. See the ConfigState documentation for more details.
+
+```
+* Indent
+	String to use for each indentation level for Dump functions.
+	It is a single space by default.  A popular alternative is "\t".
+
+* MaxDepth
+	Maximum number of levels to descend into nested data structures.
+	There is no limit by default.
+
+* DisableMethods
+	Disables invocation of error and Stringer interface methods.
+	Method invocation is enabled by default.
+
+* DisablePointerMethods
+	Disables invocation of error and Stringer interface methods on types
+	which only accept pointer receivers from non-pointer variables.  This option
+	relies on access to the unsafe package, so it will not have any effect when
+	running in environments without access to the unsafe package such as Google
+	App Engine or with the "disableunsafe" build tag specified.
+	Pointer method invocation is enabled by default.
+
+* ContinueOnMethod
+	Enables recursion into types after invoking error and Stringer interface
+	methods. Recursion after method invocation is disabled by default.
+
+* SortKeys
+	Specifies map keys should be sorted before being printed. Use
+	this to have a more deterministic, diffable output.  Note that
+	only native types (bool, int, uint, floats, uintptr and string)
+	and types which implement error or Stringer interfaces are supported,
+	with other types sorted according to the reflect.Value.String() output
+	which guarantees display stability.  Natural map order is used by
+	default.
+
+* SpewKeys
+	SpewKeys specifies that, as a last resort attempt, map keys should be
+	spewed to strings and sorted by those strings.  This is only considered
+	if SortKeys is true.
+
+```
+
+## Unsafe Package Dependency
+
+This package relies on the unsafe package to perform some of the more advanced
+features, however it also supports a "limited" mode which allows it to work in
+environments where the unsafe package is not available.  By default, it will
+operate in this mode on Google App Engine.  The "disableunsafe" build tag may
+also be specified to force the package to build without using the unsafe
+package.

+Package spew implements a deep pretty printer for Go data structures to aid in
+debugging.
+
+A quick overview of the additional features spew provides over the built-in
+printing facilities for Go data types are as follows:
+
+	* Pointers are dereferenced and followed
+	* Circular data structures are detected and handled properly
+	* Custom Stringer/error interfaces are optionally invoked, including
+	  on unexported types
+	* Custom types which only implement the Stringer/error interfaces via
+	  a pointer receiver are optionally invoked when passing non-pointer
+	  variables
+	* Byte arrays and slices are dumped like the hexdump -C command which
+	  includes offsets, byte values in hex, and ASCII output (only when using
+	  Dump style)
+
+There are two different approaches spew allows for dumping Go data structures:
+
+	* Dump style which prints with newlines, customizable indentation,
+	  and additional debug information such as types and all pointer addresses
+	  used to indirect to the final value
+	* A custom Formatter interface that integrates cleanly with the standard fmt
+	  package and replaces %v, %+v, %#v, and %#+v to provide inline printing
+	  similar to the default %v while providing the additional functionality
+	  outlined above and passing unsupported format verbs such as %x and %q
+	  along to fmt
+
+Quick Start
+
+This section demonstrates how to quickly get started with spew.  See the
+sections below for further details on formatting and configuration options.
+
+To dump a variable with full newlines, indentation, type, and pointer
+information use Dump, Fdump, or Sdump:
+	spew.Dump(myVar1, myVar2, ...)
+	spew.Fdump(someWriter, myVar1, myVar2, ...)
+	str := spew.Sdump(myVar1, myVar2, ...)
+
+Alternatively, if you would prefer to use format strings with a compacted inline
+printing style, use the convenience wrappers Printf, Fprintf, etc with
+%v (most compact), %+v (adds pointer addresses), %#v (adds types), or
+%#+v (adds types and pointer addresses):
+	spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+	spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+	spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+	spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+
+Configuration Options
+
+Configuration of spew is handled by fields in the ConfigState type.  For
+convenience, all of the top-level functions use a global state available
+via the spew.Config global.
+
+It is also possible to create a ConfigState instance that provides methods
+equivalent to the top-level functions.  This allows concurrent configuration
+options.  See the ConfigState documentation for more details.
+
+The following configuration options are available:
+	* Indent
+		String to use for each indentation level for Dump functions.
+		It is a single space by default.  A popular alternative is "\t".
+
+	* MaxDepth
+		Maximum number of levels to descend into nested data structures.
+		There is no limit by default.
+
+	* DisableMethods
+		Disables invocation of error and Stringer interface methods.
+		Method invocation is enabled by default.
+
+	* DisablePointerMethods
+		Disables invocation of error and Stringer interface methods on types
+		which only accept pointer receivers from non-pointer variables.
+		Pointer method invocation is enabled by default.
+
+	* ContinueOnMethod
+		Enables recursion into types after invoking error and Stringer interface
+		methods. Recursion after method invocation is disabled by default.
+
+	* SortKeys
+		Specifies map keys should be sorted before being printed. Use
+		this to have a more deterministic, diffable output.  Note that
+		only native types (bool, int, uint, floats, uintptr and string)
+		and types which implement error or Stringer interfaces are
+		supported with other types sorted according to the
+		reflect.Value.String() output which guarantees display
+		stability.  Natural map order is used by default.
+
+	* SpewKeys
+		Specifies that, as a last resort attempt, map keys should be
+		spewed to strings and sorted by those strings.  This is only
+		considered if SortKeys is true.
+
+Dump Usage
+
+Simply call spew.Dump with a list of variables you want to dump:
+
+	spew.Dump(myVar1, myVar2, ...)
+
+You may also call spew.Fdump if you would prefer to output to an arbitrary
+io.Writer.  For example, to dump to standard error:
+
+	spew.Fdump(os.Stderr, myVar1, myVar2, ...)
+
+A third option is to call spew.Sdump to get the formatted output as a string:
+
+	str := spew.Sdump(myVar1, myVar2, ...)
+
+Sample Dump Output
+
+See the Dump example for details on the setup of the types and variables being
+shown here.
+
+	(main.Foo) {
+	 unexportedField: (*main.Bar)(0xf84002e210)({
+	  flag: (main.Flag) flagTwo,
+	  data: (uintptr) <nil>
+	 }),
+	 ExportedField: (map[interface {}]interface {}) (len=1) {
+	  (string) (len=3) "one": (bool) true
+	 }
+	}
+
+Byte (and uint8) arrays and slices are displayed uniquely like the hexdump -C
+command as shown.
+	([]uint8) (len=32 cap=32) {
+	 00000000  11 12 13 14 15 16 17 18  19 1a 1b 1c 1d 1e 1f 20  |............... |
+	 00000010  21 22 23 24 25 26 27 28  29 2a 2b 2c 2d 2e 2f 30  |!"#$%&'()*+,-./0|
+	 00000020  31 32                                             |12|
+	}
+
+Custom Formatter
+
+Spew provides a custom formatter that implements the fmt.Formatter interface
+so that it integrates cleanly with standard fmt package printing functions. The
+formatter is useful for inline printing of smaller data types similar to the
+standard %v format specifier.
+
+The custom formatter only responds to the %v (most compact), %+v (adds pointer
+addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
+combinations.  Any other verbs such as %x and %q will be sent to the the
+standard fmt package for formatting.  In addition, the custom formatter ignores
+the width and precision arguments (however they will still work on the format
+specifiers not handled by the custom formatter).
+
+Custom Formatter Usage
+
+The simplest way to make use of the spew custom formatter is to call one of the
+convenience functions such as spew.Printf, spew.Println, or spew.Printf.  The
+functions have syntax you are most likely already familiar with:
+
+	spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+	spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+	spew.Println(myVar, myVar2)
+	spew.Fprintf(os.Stderr, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+	spew.Fprintf(os.Stderr, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+
+See the Index for the full list convenience functions.
+
+Sample Formatter Output
+
+Double pointer to a uint8:
+	  %v: <**>5
+	 %+v: <**>(0xf8400420d0->0xf8400420c8)5
+	 %#v: (**uint8)5
+	%#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
+
+Pointer to circular struct with a uint8 field and a pointer to itself:
+	  %v: <*>{1 <*><shown>}
+	 %+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)<shown>}
+	 %#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)<shown>}
+	%#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)<shown>}
+
+See the Printf example for details on the setup of variables being shown
+here.
+
+Errors
+
+Since it is possible for custom Stringer/error interfaces to panic, spew
+detects them and handles them internally by printing the panic information
+inline with the output.  Since spew is intended to provide deep pretty printing
+capabilities on structures, it intentionally does not return any errors.

+NewFormatter returns a custom formatter that satisfies the fmt.Formatter

+printing functions.  The formatter is useful for inline printing of smaller data
+types similar to the standard %v format specifier.
+
+The custom formatter only responds to the %v (most compact), %+v (adds pointer
+addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
+combinations.  Any other verbs such as %x and %q will be sent to the the
+standard fmt package for formatting.  In addition, the custom formatter ignores
+the width and precision arguments (however they will still work on the format
+specifiers not handled by the custom formatter).
+
+Typically this function shouldn't be called directly.  It is much easier to make
+use of the custom formatter by calling one of the convenience functions such as
+Printf, Println, or Fprintf.

+
+#### Print Level
+```
+Ldebug        = 1 << iota //
+Linfo                     //
+Lwarn                     //
+Lerror                    //
+Lfatal                    //
+
+logd.Printf()
+logd.Print()
+logd.Debugf()
+logd.Debug()
+logd.Infof()
+logd.Info()
+logd.Warnf()
+logd.Warn()
+logd.Errorf()
+logd.Error()
+logd.Fatalf()
+logd.Fatal()
+```
+5种日志等级，12种打印方法，完全理解你记录日志的需求。
+
+```
+Ldebug < Linfo < Lwarn < Lerror < Lfatal
+```
+通过`SetLevel()`方法设置，如：logd.SetLevel(Lwarn)，系统只会打印大于等于Lwarn的日志。
+
+> 注意：logd.Printf() 和 logd.Print() 不论等级为什么都会输出，请悉知。
+
+#### Print Option
+系统提供多种格式输出选项：
+```
+Lasync                    // 异步输出日志
+Ldate                     // like 2006/01/02
+Ltime                     // like 15:04:05
+Lmicroseconds             // like 15:04:05.123123
+Llongfile                 // like /a/b/c/d.go:23
+Lshortfile                // like d.go:23
+LUTC                      // 时间utc输出
+Ldaily                    // 按天归档
+
+默认提供：
+ LstdFlags // 2006/01/02 15:04:05.123123, /a/b/c/d.go:23
+```
+
+#### 使用方法
+1、默认方式
+
+默认方式使用以下配置选项：
+```
+// 2006/01/02 15:04:05.123123, /a/b/c/d.go:23
+Lall      = Ldebug | Linfo | Lwarn | Lerror | Lfatal
+LstdFlags = Lall | Ldate | Lmicroseconds | Lshortfile
+```
+这里会打印所有等级日志，打印日志格式为`2006/01/02 15:04:05.123123, /a/b/c/d.go:23`
+
+可以通过`logd.SetLevel(level)`方式调整日志等级。`logd.SetOutput(writer)`输出日志到别的地方。例子：
+```
+package main
+
+import (
+	"fmt"
+	"os"
+
+	"github.com/deepzz0/logd"
+)
+
+func main() {
+	logd.Printf("Printf: foo\n")
+	logd.Print("Print: foo")
+
+	logd.Debugf("Debugf: foo\n")
+	logd.Debug("Debug: foo")
+
+	logd.Errorf("Errorf: foo\n")
+	logd.Error("Error: foo")
+
+	// 改变输出等级
+	logd.SetLevel(logd.Lerror)
+	// 不论等级如何都会输出
+	fmt.Println("----- 改变日志等级为Lerror -----")
+	logd.Printf("Printf: foo\n")
+	logd.Print("Print: foo")
+
+	logd.Debugf("Debugf: foo\n")
+	logd.Debug("Debug: foo")
+
+	logd.Errorf("Errorf: foo\n")
+	logd.Error("Error: foo")
+
+	fmt.Println("----- 日志等级为Lerror并写入到test.log中 -----")
+	f, err := os.Create("./test.log")
+	if err != nil {
+		panic(err)
+	}
+	defer f.Close()
+
+	logd.SetOutput(f)
+
+	logd.Printf("Printf: foo\n")
+	logd.Print("Print: foo")
+
+	logd.Debugf("Debugf: foo\n")
+	logd.Debug("Debug: foo")
+
+	logd.Errorf("Errorf: foo\n")
+	logd.Error("Error: foo")
+}
+```
+输出如下：
+![logd_print](http://7xokm2.com1.z0.glb.clouddn.com/img/logd_print.png)
+
+
+1、自定义配置
+推荐需要将日志保存下来的用户使用。
+
+```
+Flags := Lwarn | Lerror | Lfatal | Ldate | Ltime | Lshortfile | Ldaily | Lasync
+
+f, _ := os.OpenFile("testdata/onlyfile.log", os.O_CREATE|os.O_APPEND|os.O_WRONLY, 0666)
+log := New(LogOption{
+	Out:        f,
+	Flag:       Flags,
+	LogDir:     "testdata",
+	ChannelLen: 1000,
+})
+```
+
+* 输出日志等级：Lwarn | Lerror | Lfatal
+* 输出日志格式：Ldate | Ltime | Lshortfile
+* 按日归档：Ldaily
+* 异步输出：Lasync

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications

+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+

+
+      (b) You must cause any modified files to carry prominent notices

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+
+// Package redis is a client for the Redis database.
+//
+// The Redigo FAQ (https://github.com/garyburd/redigo/wiki/FAQ) contains more
+// documentation about this package.
+//
+// Connections
+//
+// The Conn interface is the primary interface for working with Redis.
+// Applications create connections by calling the Dial, DialWithTimeout or
+// NewConn functions. In the future, functions will be added for creating
+// sharded and other types of connections.
+//
+// The application must call the connection Close method when the application
+// is done with the connection.
+//
+// Executing Commands
+//
+// The Conn interface has a generic method for executing Redis commands:
+//
+//  Do(commandName string, args ...interface{}) (reply interface{}, err error)
+//
+// The Redis command reference (http://redis.io/commands) lists the available
+// commands. An example of using the Redis APPEND command is:
+//
+//  n, err := conn.Do("APPEND", "key", "value")
+//
+// The Do method converts command arguments to bulk strings for transmission
+// to the server as follows:
+//
+//  Go Type                 Conversion
+//  []byte                  Sent as is
+//  string                  Sent as is
+//  int, int64              strconv.FormatInt(v)
+//  float64                 strconv.FormatFloat(v, 'g', -1, 64)
+//  bool                    true -> "1", false -> "0"
+//  nil                     ""
+//  all other types         fmt.Fprint(w, v)
+//
+// Redis command reply types are represented using the following Go types:
+//
+//  Redis type              Go type
+//  error                   redis.Error
+//  integer                 int64
+//  simple string           string
+//  bulk string             []byte or nil if value not present.
+//  array                   []interface{} or nil if value not present.
+//
+// Use type assertions or the reply helper functions to convert from
+// interface{} to the specific Go type for the command result.
+//
+// Pipelining
+//
+// Connections support pipelining using the Send, Flush and Receive methods.
+//
+//  Send(commandName string, args ...interface{}) error
+//  Flush() error
+//  Receive() (reply interface{}, err error)
+//
+// Send writes the command to the connection's output buffer. Flush flushes the
+// connection's output buffer to the server. Receive reads a single reply from
+// the server. The following example shows a simple pipeline.
+//
+//  c.Send("SET", "foo", "bar")
+//  c.Send("GET", "foo")
+//  c.Flush()
+//  c.Receive() // reply from SET
+//  v, err = c.Receive() // reply from GET
+//
+// The Do method combines the functionality of the Send, Flush and Receive
+// methods. The Do method starts by writing the command and flushing the output
+// buffer. Next, the Do method receives all pending replies including the reply
+// for the command just sent by Do. If any of the received replies is an error,
+// then Do returns the error. If there are no errors, then Do returns the last
+// reply. If the command argument to the Do method is "", then the Do method
+// will flush the output buffer and receive pending replies without sending a
+// command.
+//
+// Use the Send and Do methods to implement pipelined transactions.
+//
+//  c.Send("MULTI")
+//  c.Send("INCR", "foo")
+//  c.Send("INCR", "bar")
+//  r, err := c.Do("EXEC")
+//  fmt.Println(r) // prints [1, 1]
+//
+// Concurrency
+//
+// Connections support one concurrent caller to the Receive method and one
+// concurrent caller to the Send and Flush methods. No other concurrency is
+// supported including concurrent calls to the Do method.
+//
+// For full concurrent access to Redis, use the thread-safe Pool to get, use
+// and release a connection from within a goroutine. Connections returned from
+// a Pool have the concurrency restrictions described in the previous
+// paragraph.
+//
+// Publish and Subscribe
+//
+// Use the Send, Flush and Receive methods to implement Pub/Sub subscribers.
+//
+//  c.Send("SUBSCRIBE", "example")
+//  c.Flush()
+//  for {
+//      reply, err := c.Receive()
+//      if err != nil {
+//          return err
+//      }
+//      // process pushed message

+// The PubSubConn type wraps a Conn with convenience methods for implementing
+// subscribers. The Subscribe, PSubscribe, Unsubscribe and PUnsubscribe methods
+// send and flush a subscription management command. The receive method
+// converts a pushed message to convenient types for use in a type switch.
+//
+//  psc := redis.PubSubConn{Conn: c}
+//  psc.Subscribe("example")
+//  for {
+//      switch v := psc.Receive().(type) {
+//      case redis.Message:
+//          fmt.Printf("%s: message: %s\n", v.Channel, v.Data)
+//      case redis.Subscription:
+//          fmt.Printf("%s: %s %d\n", v.Channel, v.Kind, v.Count)
+//      case error:
+//          return v
+//      }
+//  }
+//
+// Reply Helpers
+//
+// The Bool, Int, Bytes, String, Strings and Values functions convert a reply
+// to a value of a specific type. To allow convenient wrapping of calls to the
+// connection Do and Receive methods, the functions take a second argument of
+// type error.  If the error is non-nil, then the helper function returns the
+// error. If the error is nil, the function converts the reply to the specified
+// type:
+//
+//  exists, err := redis.Bool(c.Do("EXISTS", "foo"))
+//  if err != nil {
+//      // handle error return from c.Do or type conversion error.
+//  }
+//
+// The Scan function converts elements of a array reply to Go types:
+//
+//  var value1 int
+//  var value2 string
+//  reply, err := redis.Values(c.Do("MGET", "key1", "key2"))
+//  if err != nil {
+//      // handle error
+//  }
+//   if _, err := redis.Scan(reply, &value1, &value2); err != nil {
+//      // handle error
+//  }
+//
+// Errors
+//
+// Connection methods return error replies from the server as type redis.Error.
+//
+// Call the connection Err() method to determine if the connection encountered
+// non-recoverable error such as a network error or protocol parsing error. If
+// Err() returns a non-nil value, then the connection is not usable and should
+// be closed.
