### redis连接： ###

redis连接命令主要用于连接redis服务

实例：通过密码验证连接到redis服务，并检测服务是否正在运行：

redis 127.0.0.1:6379> AUTH "password"
    OK
    redis 127.0.0.1:6379> PING
    PONG

**redis连接命令：**

 <tbody> 
  <tr> 
   <td>1</td> 
   <td>auth password</td> 
   <td>验证密码是否正确</td> 
  </tr> 
  <tr> 
   <td>2</td> 
   <td>echo message</td> 
   <td>打印字符串</td> 
  </tr> 
  <tr> 
   <td>3</td> 
   <td>ping</td> 
   <td>查看服务是否运行</td> 
  </tr> 
  <tr> 
   <td>4</td> 
   <td>quit</td> 
   <td>关闭当前连接</td> 
  </tr> 
  <tr> 
   <td>5</td> 
   <td>select index</td> 
   <td>切换到指定的数据库</td> 
  </tr>

### redis服务器： ###

redis服务器命令主要用于管理redis服务。
