进入容器redis-node-1并为6台机器构建集群关系

1.进入容器
    docker exec -it redis-node-1 /bin/bash
    
2.#注意，进入docker容器后才能执行一下命令，且注意自己的真实IP地址
    redis-cli --cluster create IP地址:6381 IP地址:6382                IP地址:6383 192.168.111.147:6384 IP地址:6385        IP地址:6386 --cluster-replicas 1
    #--cluster-replicas 1 表示为每个master创建一个slave节点
    
3.#3主3从搞定

运行结果

[root@localhost home]# docker exec -it redis-node-1 /bin/bash
root@localhost:/data# redis-cli --cluster create 192.168.153.138:6381 192.168.153.138:6382 192.168.153.138:6383 192.168.153.138:6384 192.168.153.138:6385    192.168.153.138:6386 --cluster-replicas 1
