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
