1、环境说明
1. 前提：本试验环境已经提前安装了docker和docker-compose
2. 说明：本次部署是单机伪集群，想要部署真正的集群，需要将秒个主件拆分到各个机器上去部署，只修改ip地址
2、redis三种集群
1. 主从（主从同步原理）
2. sentinel（哨兵模式）
3. codis
详细内容请参考：https://www.cnblogs.com/xiaonq/p/11635195.html
1、参考博客
docker-compose部署：https://www.cnblogs.com/boshen-hzb/p/10471665.html
普通部署：https://www.cnblogs.com/kevingrace/p/9004460.html
2、使用docker-compose部署
redis-sentinel # 项目根路径
├── docker-compose.yml # docker-compose文件
└── sentinel # 存放初始化sentinel容器的相关文件
├── Dockerfile # sentinel构建镜像文件
├── sentinel.conf # sentinel配置文件
└── sentinel-entrypoint.sh # sentinel.sh启动脚本
