使用Docker Compose搭建高可用Redis集群( 五 )

Redis

  • 192.168.0.195服务器上部署三个Redis服务的docker-compose-redis-cluster.yml文件

docker-compose-redis-cluster.yml上传至/opt/software目录，这个目录可以自己选择 ， 然后到目录下执行安装启动命令
docker-compose -f docker-compose-redis-cluster.yml up -d[+] Running 3/3 ? Container redis-cluster3Started0.5s ? Container redis-cluster2Started0.4s ? Container redis-cluster1Started0.5s通过docker ps命令可以看到redis和redis哨兵已经安装并启动成功

  • 登录到docker容器中
docker exec -it 67a48962160d bash
  • 用redis-cli创建整个redis集群
