+  2. 搭建 `MongoDB`（必须）和 `Elasticsearch`（可选）服务，正式部署需要。
+  3. `MongoDB` 服务地址也可通过环境变量指定连接地址如：`export EIBLOG_MGO_ADDR=127.0.0.1:27017`。
+  4. 执行 `./eiblog`，运行博客系统。看到 `...Listening and serving HTTP on :9000` 代表运行成功了。
 
 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。
 
+2、Docker 与 Go 环境
+
+如果你有 `docker` 和 `go` 环境，可直接使用如下命令启动：
+```
+$ EIBLOG_MGO_ADDR=127.0.0.1:27017 make run
+```
+请提前指定 `mongodb` 的连接地址。该命令会启动一个 `mognodb` 容器，然后编译 `eiblog` 并运行。

+[![Build Status](https://travis-ci.org/boj/redistore.svg?branch=master)](https://travis-ci.org/boj/redistore)
+
+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/gomodule/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)

+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.
+
+	* DisablePointerAddresses
+		DisablePointerAddresses specifies whether to disable the printing of
+		pointer addresses. This is useful when diffing data structures in tests.
+
+	* DisableCapacities
+		DisableCapacities specifies whether to disable the printing of
+		capacities for arrays, slices, maps and channels. This is useful when
+		diffing data structures in tests.
+
+	* 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.

+	* Byte arrays and slices are dumped like the hexdump -C command which
+	  includes offsets, byte values in hex, and ASCII output
+
+The configuration options are controlled by an exported package global,
+spew.Config.  See ConfigState for options documentation.
+
+See Fdump if you would prefer dumping to an arbitrary io.Writer or Sdump to
+get the formatted result as a string.

+NewFormatter returns a custom formatter that satisfies the fmt.Formatter
+interface.  As a result, 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).
+
+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.

+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
+
+它会将每天的日志，采用 gzip 压缩，并保留 30 天以内的日志。自动删除 30 以前的日志。

+
+Server-sent events (SSE) is a technology where a browser receives automatic updates from a server via HTTP connection. The Server-Sent Events EventSource API is [standardized as part of HTML5[1] by the W3C](http://www.w3.org/TR/2009/WD-eventsource-20091029/).
+
+- [Read this great SSE introduction by the HTML5Rocks guys](http://www.html5rocks.com/en/tutorials/eventsource/basics/)
+- [Browser support](http://caniuse.com/#feat=eventsource)
+
+## Sample code
+
+```go
+import "github.com/gin-contrib/sse"
+
+func httpHandler(w http.ResponseWriter, req *http.Request) {
+	// data can be a primitive like a string, an integer or a float
+	sse.Encode(w, sse.Event{
+		Event: "message",
+		Data:  "some data\nmore data",
+	})
+
+	// also a complex type, like a map, a struct or a slice
+	sse.Encode(w, sse.Event{
+		Id:    "124",
+		Event: "message",
+		Data: map[string]interface{}{
+			"user":    "manu",
+			"date":    time.Now().Unix(),
+			"content": "hi!",
+		},
+	})
+}
+```
+```
+event: message
+data: some data\\nmore data
+
+id: 124
+event: message
+data: {"content":"hi!","date":1431540810,"user":"manu"}
+ 
+```
+
+## Content-Type
+
+```go
+fmt.Println(sse.ContentType)
+```
+```
+text/event-stream
+```
+
+## Decoding support
+
+There is a client-side implementation of SSE coming soon.
