*  问题：客户端连接后操作redis可能会报如下错误：
    
        127.0.0.1:6379> get title
        (error) CLUSTERDOWN Hash slot not served
 *  ★★解决方法★★：  
    断开客户端连接，敲如下命令检测一下：
    
        ./redis-cli --cluster check 127.0.0.1:6379
    
    提示如下：
    
    > 127.0.0.1:6379 (9a8dd4a7…) -> 0 keys | 0 slots | 0 slaves.  
    > \[OK\] 0 keys in 1 masters.  
    > 0.00 keys per slot on average.  
    > >>> Performing Cluster Check (using node 127.0.0.1:6379)  
    > M: 9a8dd4a7fe734cbe58196a2d380392c3064dbfe8 127.0.0.1:6379  
    >  slots: (0 slots) master  
    > \[OK\] All nodes agree about slots configuration.  
    > >>> Check for open slots…  
    > >>> Check slots coverage…  
    > \[ERR\] Not all 16384 slots are covered by nodes.
    
    执行修复命令：
    
        ./redis-cli --cluster fix 127.0.0.1:6379
    
    中途提示：
    
    > Fix these slots by covering with a random node? (type ‘yes’ to accept):
    
    输入“yes”，回车  
    再次输入上述检测命令，提示如下，则修复成功：
    
    > 127.0.0.1:6379 (9a8dd4a7…) -> 0 keys | 16384 slots | 0 slaves.  
    > \[OK\] 0 keys in 1 masters.  
    > 0.00 keys per slot on average.

    > \[OK\] All nodes agree about slots configuration.

    > \[OK\] All 16384 slots covered.
