DockerCompose搭建redis一主二从三哨兵

此版本为无密码配置版本，关于compose请查阅我其它文章，这里不再描述。

#######步骤1:home下创建文件夹:sentinelredis,按照图片创建三个文件夹。
如图:

步骤2:每个文件夹下对应描述:

masterslave: docker-compose.yml
redisconf: sentinel.conf
sentinel: docker-compose.yml , sentinel1.conf , sentinel2.conf, sentinel3.conf
文件内容如下:

masterslave: docker-compose.yml

version: '3.7'
services:
  master:
    image: redis
    container_name: redis-master
    restart: always
    command: bash -c "redis-server --protected-mode no --slave-announce-ip {宿主机ip地址}  --slave-announce-port 6379"
    ports:
      - 6379:6379
    #数据卷目录挂载,都是当前目录，跟yml文件同级
    volumes:
      - ./data1:/data
  slave1:
    image: redis
    container_name: redis-slave-1
    restart: always
    command: bash -c "redis-server --protected-mode no --slaveof redis-master 6379 --slave-announce-ip  {宿主机ip地址} --slave-announce-port 6380"
    ports:
      - 6380:6379
    volumes:
      - ./data2:/data
  slave2:
    image: redis
    container_name: redis-slave-2
    restart: always
    command: bash -c "redis-server --protected-mode no --slaveof redis-master 6379 --slave-announce-ip {宿主机ip地址} --slave-announce-port 6381"
    ports:
      - 6381:6379
    volumes:
      - ./data3:/data

redisconf: sentinel.conf

#6379 为 redis-master 的端口，2 为最小投票数（因为有 3 台 Sentinel 所以可以设置成 #2）,kingmaster是可以自定义集群的名字
port 26379
dir /tmp
sentinel monitor kingmaster {宿主机ip地址} 6379 2
sentinel down-after-milliseconds kingmaster 30000
sentinel parallel-syncs kingmaster 1
sentinel failover-timeout kingmaster 180000
sentinel deny-scripts-reconfig yes

sentinel: docker-compose.yml , sentinel1.conf , sentinel2.conf, sentinel3.conf

version: '3.7'
services:
  sentinel1:
    image: redis
    container_name: redis-sentinel-1
    restart: always
    ports:
      - 26379:26379
    command: redis-sentinel /home/sentinelredis/redisconf/sentinel.conf
    volumes:
      - ./sentinel1.conf:/home/sentinelredis/redisconf/sentinel.conf
  sentinel2:
    image: redis
    container_name: redis-sentinel-2
    restart: always
    ports:
    - 26380:26379
    command: redis-sentinel /home/sentinelredis/redisconf/sentinel.conf
    volumes:
      - ./sentinel2.conf:/home/sentinelredis/redisconf/sentinel.conf
  sentinel3:
    image: redis
    container_name: redis-sentinel-3
    ports:
      - 26381:26379
    command: redis-sentinel /home/sentinelredis/redisconf/sentinel.conf
    volumes:
      - ./sentinel3.conf:/home/sentinelredis/redisconf/sentinel.conf
networks:
  default:
#关于masterslave_default配置，docker compose会自动创建一个网络，就是以文件夹的名称+_default命名。可以执行命令 docker network ls，找到
    name: masterslave_default
    external: true

port 26379
dir /tmp
sentinel monitor kingmaster  {宿主机ip地址}  6379 2
sentinel down-after-milliseconds kingmaster 30000
sentinel parallel-syncs kingmaster 1
sentinel failover-timeout kingmaster 180000
sentinel deny-scripts-reconfig yes

port 26379
dir /tmp
sentinel monitor kingmaster  {宿主机ip地址}  6379 2
sentinel down-after-milliseconds kingmaster 30000
sentinel parallel-syncs kingmaster 1
sentinel failover-timeout kingmaster 180000
sentinel deny-scripts-reconfig yes

port 26379
dir /tmp
sentinel monitor kingmaster  {宿主机ip地址}  6379 2
sentinel down-after-milliseconds kingmaster 30000
sentinel parallel-syncs kingmaster 1
sentinel failover-timeout kingmaster 180000
sentinel deny-scripts-reconfig yes

开始启动测试:

1. 进入主从配置文件夹:

   
   image.png
   

   2.启动成功:

   
   image.png
   3：进入主从查看信息:
   进入主节点:
   image.png
   image.png
   

   进入从节点:

   
   image.png

   4.启动哨兵
   image.png
   [图片上传中...(image.png-edaeaf-1714293208948-0)]

验证哨兵:

重新创建容器实现修改:
docker-compose up --force-recreate -d

docker exec -it redis-sentinel-2 redis-cli -h {宿主机ip地址}  -p 26381 info sentinel

如图:

5.关于主从通信测试，哨兵选举测试这里不再描述。

启动成功后，springboot项目配置启动;
