查看主从状态
进入master 查看
docker exec -it 容器名称或容器id bash
redis-cli -p 端口 -h ip地址 -a 密码
info replication 查看主从信息
这里可以看到 当前角色是master 有2个slave ip信息都能看到
这样我们的redis主从就搭建完了
部署哨兵节点
每个节点都需要操作
修改 ip地址为master的宿主机ip
vim /mnt/data/redis/sentinel.conf
port 26380
daemonize no
pidfile /var/run/redis-sentinel.pid
logfile "/data/sentinel.log"
dir /tmp
sentinel monitor mymaster (master对于的宿主机地址) 6380 2
sentinel auth-pass mymaster 密码
sentinel down-after-milliseconds mymaster 30000
sentinel parallel-syncs mymaster 1
sentinel failover-timeout mymaster 180000
sentinel deny-scripts-reconfig yes
sentinel.yml
version: '3.9'
services:
sentinel:
restart: always
image: "redis:6.0.9"
container_name: sentinel
ports:
- "26380:26380"
volumes:
- /mnt/data/redis/sentinel.conf:/etc/redis/sentinel.conf
- /mnt/data/redis/data:/data
command:
redis-sentinel /etc/redis/sentinel.conf
docker-compose -f sentinel.yml up -d
验证哨兵
启动三台sentinel容器后,随便进入一台容器
docker exec -it 哨兵容器 bash
redis-cli -p 端口
sentinel master (集群名)
sentinel master mymaster
故障测试
将master节点的redis关闭
可以看到ip跳动到其他节点了
开启master节点的redis变为从节点了
