加载集群(需同步开放17001-17006端口)
/usr/local/bin/redis-cli --cluster create ip地址:7001 ip地址:7002 ip地址:7003 ip地址:7004 ip地址:7005 ip地址:7006 --cluster-replicas 1 -a 123456
登录redis
redis-cli -h 127.0.0.1 -p 7001
检查集群配置
CLUSTER NODES
docker容器里安装vim命令
apt-get update
apt-get install vim
docker部署、云服务可能碰到（客户端连接后IP变成内网地址、需指定conf文件中得地址为外网）
cluster-announce-ip 10.1.1.5
这是redis.conf 中的原文 大致意思是在docker或者某些部署中 因为端口被转发等其他原因 会导致地址发送变化，所以在配置中写死地址就可以解决
非docker部署时解决方案 执行命令
1.config set cluster-announce-ip 阿里云redis的ip地址
2. config rewrite
3. exit
