    • Master 密码不对
      即配置的 master 密码不对,导致验证不通过而无法建立主从同步关系

    • Redis 版本不一致
      不同的 redis 版本之间存在兼容性问题,因此各 master 和 slave 之间必须保持版本一致

    • 无法远程连接
      在开启了安全模式情况下,没有设置 bind 地址和密码

    [root@redis-s1 ~]# redis-cli  -h 192.168.7.104 
    192.168.7.104:6379> KEYS * 
    (error) DENIED Redis is running in protected mode because protected mode is enabled, no bind address was specified, no authentication password  
    is requested to clients. In this mode connections are only accepted from the loopback interface. If you want to connect from external computers to Redis you may adopt one of the following solutions:  
    1) Just disable protected mode sending the command 'CONFIG SET protected-mode no' from 
    the loopback interface by connecting to Redis from the same host the server is running, however MAKE SURE Redis is not publicly accessible from internet if you do so. Use CONFIG REWRITE to make this change permanent.  
    2) Alternatively you can just disable the protected mode by editing the Redis configuration file, and setting the protected mode option to 'no', and then restarting the server.  
    3) If you started the server manually just for testing, restart it with the '--protected-mode no' option.  
    4) Setup a bind address or an authentication password. NOTE: You only need to do one of the above things in order for the server to start accepting connections from the outside.
