基于DockerCompose搭建Redis主从哨兵模式

linux目录结构

内网配置

哨兵配置文件如下，创建3个哨兵配置文件

# sentinel26379.conf  sentinel26380.conf  sentinel26381.conf 内容如下
protected-mode no
sentinel monitor mymaster redis-master 6379 2
sentinel down-after-milliseconds mymaster 60000
sentinel failover-timeout mymaster 180000
sentinel parallel-syncs mymaster 1
