2、原因分析
造成此异常，通常是以下两种原因：
1)启动 redis-cli时未设置集群模式；
2)开启集群后，redis-cli用普通用户登录无法操作集群数据，需加上-c，采用集群模式登录.

3、解决过程
192.168.133.97:6001> exit
You have new mail in /var/spool/mail/redis

[redis@redis-leo-master ~]$ /opt/redis/bin/redis-cli -h 192.168.133.97 -c -p 6001 -a rcpassword1 
Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe.
192.168.133.97:6001> set k1 v1
-> Redirected to slot [12706] located at 192.168.133.99:6001
OK
192.168.133.99:6001> get k1
"v1"

说明：如上所示，添加-c登录数据库后，成功添加键值k1.
