1. 两台机器,将下边的脚本分别在两台机器上执行；sh redis.sh
  2. 进入任意一个docker容器内并启动集群服务：```

    docker exec -it $(docker ps | grep 600 |head -n 1| awk ‘{print $1}’) bash

    redis-cli —cluster create IP1:6001 IP1:6002 IP1:6003 IP2:6004 IP2:6005 IP2:6006 —cluster-replicas 1

    输入完上条命令后，需要输入yes完成集群创建 ```

注意：脚本是已6001-6006为集群的监听端口，如需其他端口，修改对应的脚本和命令。
