   > db.shutdownServer();  
   

2. 启动 mongod

   $ ./mongod -config mongodb.conf
   

3. mongodb.conf

   $ vim mongodb.conf
   
   systemLog:
   	destination: file
   	path: /the/path/to/log/mongodb.log
   	logAppend: true
   storage:
     	dbPath: /the/path/to/data/
   net:
   	bindIp: 127.0.0.1
   processManagement:
   	fork: true
   security:
   	authorization: enabled # enabled/disabled #开启客户端认证 
   

4. 认证

  ```
  > use [db]
  > db.auth("[user]","[password]")
  ```
  
5. mongodb golang 驱动 mgo 简单使用

  ```golang
  package main

  import (
  	"fmt"
  	"gopkg.in/mgo.v2"
  	"gopkg.in/mgo.v2/bson"
  )
  
  type People struct {
  	Name string `bson:"name"`
  }
  
  func main() {
  	session, err := mgo.Dial("mongodb://serverParkSocket:serverParkSocketAdmin123@localhost:27017/parkSocket") //传入数据库的地址，可以传入多个，具体请看接口文档
  
  	if err != nil {
  		panic(err)
  	}
  	defer session.Close() //用完记得关闭
  	c := session.DB("parkSocket").C("people1")
  
  	name := "b"
  
  	people := &People{
  		Name: name,
  	}
  
  	// 插入数据
  	err = c.Insert(people)
  	if err != nil {
  		fmt.Println(err)
  	} else {
  		fmt.Println("insert "+people.Name+ " ok")
  	}
  
  	// 查询
  	result := People{}
  	err = c.Find(bson.M{"name": "b"}).One(&result)
  	if err!=nil{
  		fmt.Println(err)
  
  	} else {
  		fmt.Println(result)
  	}
  
  }
  ```
