Redis-sentinel在docker中的坑

情景介绍:
三台宿主机,然后在上面分别用docker-compose部署Redis,Redis-sentinel,来做成Redis集群
服务原来是单机用docker-compose部署的,现在要改成高可用,时间紧,先用三台机器做个简单负载

Redis负载这里就有个大坑

表现出来就是,有个服务一直报错

2024-11-22 16:31:46.119 ERROR --- [sson-netty-2-13] o.r.connection.SentinelConnectionManager : io.netty.channel.ConnectTimeoutException: connection timed out: 172.20.0.24/172.20.0.24:26379
java.util.concurrent.CompletionException: io.netty.channel.ConnectTimeoutException: connection timed out: 172.20.0.24/172.20.0.24:26379

经过无数次的排查后发现sentinel的配置少了密码
sentinel auth-pass mymaster xxx@xxxx
加上之后满心欢喜的去重启服务,以为这就搞定了

但是服务依然报错

又经过各种查资料,发现因为redis-sentinel是用docker部署的,所以,在连接后上报的地址是docker容器的地址,这就会有问题,而且三台主机的redis-sentinel容器ip还一模一样

于是,又在配置文件中加了这一行,修改上报的ip地址
sentinel announce-ip ${宿主机ip},在三台机器上分别加上这个配置

然后在重启容器,再重启服务,发现服务终于好了

正常的启动是这样的 :
