HA possibility with Redis Replication Master-Slave

[Anil Kumar Goud]

Hi,

Is it possible to get Redis High availability with Master-Slave replication? Like if Master goes down, slave1 should act as master automatically.
Or is it only possible with Redis cluster setup?

Thanks,
Anil

Hello Anil,

The cluster isn't a mandatory requirement for high availability. Redis, in single instance mode, can be made highly available via the use of Sentinel - for more details refer to: https://redis.io/topics/sentinel

Sure, that's entirely possible. Just use a cluster manager like pacemaker,
and have it run the appropriate commands to promote/demote masters and
slaves as necessary.
