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不不⽀支持同⼀一⽬目录,于是我⼿手⼯工修改sentinel.conf⽂文件的[sentinel
myid] 配置项,使⽤用Sentinel masters可以看到other sentinels为2了了.⼀一切正常.
然⽽而当我KILL掉mastera时,使⽤用Sentinel get-master-addr-by-name mastera得
到的master没有变化.怀疑⼜又是相同⽬目录原因,后我将配置⽂文件置于3个⽬目
录,Sentinel主从切换恢复正常.
下⾯面我将配置⽂文件列列出.
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
另外两个配置⽂文件只是端⼝口号不不同
redis配置⽂文件如下:
