创建集群

redis-cli -a test123456 --cluster create  172.25.0.132:6379 172.25.0.132:6380 172.25.0.132:6381 172.25.0.132:6382 172.25.0.132:6383 172.25.0.132:6384 --cluster-replicas 1

从节点设置主节点密码

[root@redis-s1 ~]# redis-cli -h 192.168.7.101 -p 6380 -a 123456 
Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe. 

192.168.7.101:6380> CONFIG SET masterauth 123456
