kubernetes中的redis ha无法故障切换回主服务器

我正在尝试创建一个简单的redis高可用性设置，包括1个主设备、1个从设备和2个Sentinel

当从

redis master

故障切换到

redis slave

时，该设置工作正常。 当

redis-master

恢复时，它会将自己正确注册为新

redis-slave

master的从机

但是，当作为主设备的

redis slave

关闭时，

redis master

无法作为主设备返回。redis master的日志进入循环，显示：

1:S 12 Dec 11:12:35.073 * MASTER <-> SLAVE sync started
1:S 12 Dec 11:12:35.073 * Non blocking connect for SYNC fired the event.
1:S 12 Dec 11:12:35.074 * Master replied to PING, replication can continue...

redis主配置 redis从配置

事实证明，问题与使用主机名而不是IP有关：

slaveof redis-master.fp8-cache 6379
...
slave-announce-ip redis-slave.fp8-cache

---

因此，当主设备作为从设备返回时，sentinel显示现在有两个从设备：一个具有ip地址，另一个具有主机名。不确定这两个从属条目（指向同一个Redis服务器）是如何导致上述问题的。现在，我将配置更改为使用IP地址而不是主机名，Redis HA工作正常。

你能分享一下你是如何更改配置的吗？不仅仅是配置。我使用

sed-I“s/\[master\u ip\]/$master\u ip/g”/etc/redis/redis.conf

脚本在pod启动时更新配置<代码>[master_ip]输入配置中，

$master_ip

是主机的实际ip地址。

requirepass test1234
masterauth test1234
dir /data

tcp-keepalive 60
maxmemory-policy noeviction
