# 前言 #

# 一：报错1与解决 #

### 1.1：报错内容 ###

*  ![mark][]
 *      Can I set the above configuration? (type 'yes' to accept): yes
        >>> Nodes configuration updated
        >>> Assign a different config epoch to each node
        >>> Sending CLUSTER MEET messages to join the cluster
        Waiting for the cluster to join
        ....................................................................................................................................................................................................................................................^C

### 1.2：问题解决 ###

*  经过排查，发现配置文件中监听的IP地址不可以有127.0.0.1的存在，只能监听各本机的IP地址
 *  经过修改并重启服务后再次创建集群立刻成功
 *      [root@localhost opt]# vi /etc/redis/6379.conf 	'//修改配置文件'
        [root@localhost opt]# /etc/init.d/redis_6379 restart	'//重启'
        Stopping ...
        Waiting for Redis to shutdown ...
        Redis stopped
        Starting Redis server...
        [root@localhost opt]# netstat -antp |grep  6379
        tcp        0      0 192.168.233.128:16379   0.0.0.0:*               LISTEN      76973/redis-server  
        tcp        0      0 192.168.233.128:6379    0.0.0.0:*               LISTEN      76973/redis-server  
        [root@localhost opt]# redis-cli --cluster create --cluster-replicas 1 192.168.233.128:6379 192.168.233.129:6379 192.168.233.130:6379 192.168.233.131:6379 192.168.233.132:6379 192.168.233.133:6379	'//重新创建集群'

# 二：报错2与解决 #

### 2.1：报错描述 ###

*  登陆集群节点查看创建的键的时候出现报错：(error) MOVED 9379 192.168.233.129:6379
 *      [root@localhost opt]# redis-cli -h 192.168.233.130 -p 6379 192.168.233.130:6379> get cent
        (error) MOVED 9379 192.168.233.129:6379

### 2.2：报错解决 ###

*  通过添加-c参数，解决问题
    
        -c:连接集群结点时使用，此选项可防止moved和ask异常
 *  重新连接查看，问题解决
    
        [root@localhost opt]# redis-cli -h 192.168.233.130 -p 6379 -c
        192.168.233.130:6379> get cent
        -> Redirected to slot [9379] located at 192.168.233.129:6379
