redis之sentinel集群

1. linux部署
   1.  redis创建
      1. 图例

          

      2. docker-compose.yml文件

         1. version: '3'
            services:
              master:
                image: redis
                container_name: redis-master
                ports:
                  - 6379:6379
              slave1:
                image: redis
                container_name: redis-master-1
                ports:
                  - 6380:6379
                command: redis-server --slaveof redis-master 6379
              slave2:
                image: redis
                container_name: redis-master-2
                ports:
                  - 6381:6379
                command: redis-server --slaveof redis-master 6379

         2. 执行docker-compost up -d

   2. sentinell集群创建
      1. 图例
         1. 
      2. docker-compose.yml文件
         1. version: '3'
            services:
              sentinel1:
                image: redis
                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
                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
                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
             
      3. sentinel1.conf文件，sentinel2.conf文件，sentinel3.conf文件
         1. port 26379
            dir /tmp
            #自定义集群名，其中127.0.0.1为redis-master的ip. 6379 为redis-master的端口. 2为最小投票数（因为有三台sentinel  所以设置成 2）
            sentinel monitor mymaster 192.168.31.39 6379 2
            sentinel down-after-milliseconds mymaster 30000
            sentinel failover-timeout mymaster 180000
            sentinel parallel-syncs mymaster 1
            sentinel deny-scripts-reconfig yes
             
      4. 执行docker-compost up -d
   3. 测试
      1. 执行docker exec -it redis-sentinel-1 bash
      2. 执行redis-cli -p 26379（sentinel的端口号）
      3. 执行sentinel master mymaster（sentinel的名字）
      4. 如果有以下这种情况，则成功
      5. 
      6. RedisDesktopManager管理工具连接
