今天来记录一下使用DockerCompose部署Redis分片集群的过程，前面写了几篇关于redis的博客了，这里就不再过多介绍了，直接上配置就好了

其中有一个redis.config配置文件。

使用docker-composer up -d启动之后 ，每个redis都是相互独立的 ，我们需要把他们加入集群

需要进入到其中任意一个docker容器当中。

查看容器

docker ps

进入到容器当中

docker exec -it redis_server1 /bin/bash

建立集群

redis-cli --cluster create --cluster-replicas 1 192.168.21.69:7001 192.168.21.69:7002 192.168.21.69:7003 192.168.21.69:7004 192.168.21.69:7005 192.168.21.69:7006

 需要确认主从配置服务，输入yes

这就搞定了

查看集群状态

redis-cli -p 7001 cluster nodes
 

 测试

测试代码地址如下：

https://gitee.com/840312696/redis-demo/tree/%E5%88%86%E7%89%87%E9%9B%86%E7%BE%A4/

向redis中插入值

从redis中查询值

 打印日志 

从日志看集群已经实现了分部署，并且是读写分离的
