redis哨兵模式配置

文件结构

1. redis （目录）
   包含文件 docker-compose.yml
   2 redis-sentinel（目录）
   包含文件docker-compose.yml、sentinel1.conf、sentinel2.conf、sentinel3.conf

redis目录下的docker-compose.yml(最好用vscode编辑，要不格式会乱）
1、docker-compose 文件实现一主两从

version: ‘3.7’
services:
master:
image: redis
container_name: redis-master
restart: always
command: redis-server --requirepass GaosiDev --masterauth GaosiDev
ports:
- 6380:6379

slave1:
image: redis
container_name: redis-slave-1
restart: always
command: redis-server --slaveof redis-master 6379 --requirepass GaosiDev --masterauth GaosiDev
ports:
- 6381:6379
slave2:
image: redis
container_name: redis-slave-2
restart: always
command: redis-server --slaveof redis-master 6379 --requirepass GaosiDev --masterauth GaosiDev
ports:
- 6382:6379

执行命令 docker-compose up -d

redis-sentinel目录
docker-compose 文件实现
version: ‘2’
services:
sentinel1:
image: redis ## 镜像
container_name: redis-sentinel-1
ports:
- “26379:26379”
command: redis-sentinel /usr/local/etc/redis/sentinel.conf
volumes:
- “./sentinel1.conf:/usr/local/etc/redis/sentinel.conf”
sentinel2:
image: redis ## 镜像
container_name: redis-sentinel-2
ports:
- “26380:26379”
command: redis-sentinel /usr/local/etc/redis/sentinel.conf
volumes:
- “./sentinel2.conf:/usr/local/etc/redis/sentinel.conf”
sentinel3:
image: redis ## 镜像
container_name: redis-sentinel-3
ports:
- “26381:26379”
command: redis-sentinel /usr/local/etc/redis/sentinel.conf
volumes:
- ./sentinel3.conf:/usr/local/etc/redis/sentinel.conf
networks:
default:
external:
name: redis-sentinel_default ##通过（docker inspect 主节点容器id）来查看，对应 NetworkMode

编辑 sentinel.conf 文件#
port 26379
dir /tmp
sentinel monitor mymaster 172.17.0.4 6379 2 #我这里用的是本机的ip
sentinel auth-pass mymaster GaosiDev
sentinel down-after-milliseconds mymaster 30000
sentinel parallel-syncs mymaster 1
sentinel failover-timeout mymaster 10000
sentinel deny-scripts-reconfig yes
