Recently, when building the Redis-sentinel test, you will encounter problems in this label. Deployment: Three Sentinel instances, Port: 36379,36380,36381, Place Sentinel configuration files in the same directory. Results running Sentinel Masters obtained the other sentinels has been 0. Found the next reason on the Internet, did not find. Then I asked my colleague for help, and I found that the IDs of the three Sentinel implementations were identical. As shown in . The initial suspicion is that Sentinel does not support the same directory, so I manually modified the [Sentinel myID] Configuration entry for the sentinel.conf file, using Sentinel Masters to see the other Sentinels is 2. Everything is fine. However, when I kill Mastera, the master with Sentinel Get-master-addr-by-name Mastera does not change. Suspect is the same directory reason, After I put the configuration file in 3 directories, Sentinel master switch back to normal . below I will list the configuration file.
