REDIS-sentinel测试环境搭建(MAC)

Posted 2020-10-15 冰冰与铛铛

最近在搭建Redis-Sentinel测试时,将遇到的问题在这标注下.

部署:

三个Sentinel实例,端口为:36379,36380,36381,将Sentinel配置文件放在同一目录下.结果运行Sentinel masters得到的Other sentinels一直为0.

在网上找了下原因,没有找到.然后我截图向同事求助,截图后发现三个Sentinel实现的ID竟然一致.如下图所示.

 

 

初步怀疑是Sentinel不支持同一目录,于是我手工修改sentinel.conf文件的[sentinel myid] 配置项,使用Sentinel masters可以看到other sentinels为2了.一切正常.

然而当我KILL掉mastera时,使用Sentinel get-master-addr-by-name mastera得到的master没有变化.怀疑又是相同目录原因,后我将配置文件置于3个目录,Sentinel主从切换恢复正常.

 

下面我将配置文件列出.

port 36379

dir "/usr/local/etc/redis"

sentinel monitor mastera 127.0.0.1 16380 2

sentinel failover-timeout mastera 6000

sentinel auth-pass mastera xxxxxxxxx

另外两个配置文件只是端口号不同

 

redis配置文件如下:
