启动redis
docker run -it -d -v /home/zyw/zpowner/dockerdata/redis-cluster/conf:/usr/local/etc/redis -v /home/zyw/zpowner/dockerdata/redis-cluster/data:/data --network=host --name redis-7001 redis:6.2 redis-server /usr/local/etc/redis/redis-7001.conf
docker run -it -d -v /home/zyw/zpowner/dockerdata/redis-cluster/conf:/usr/local/etc/redis -v /home/zyw/zpowner/dockerdata/redis-cluster/data:/data --network=host --name redis-7002 redis:6.2 redis-server /usr/local/etc/redis/redis-7002.conf
docker run -it -d -v /home/zyw/zpowner/dockerdata/redis-cluster/conf:/usr/local/etc/redis -v /home/zyw/zpowner/dockerdata/redis-cluster/data:/data --network=host --name redis-7003 redis:6.2 redis-server /usr/local/etc/redis/redis-7003.conf

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
