Redis 4.x Cookbook

Getting ready…

You need to set up one Redis master server and two slave servers. You can refer to the Setting up Redis replication section in Chapter 6, Persistence for instructions.

Role	IP address	Port
Master	192.168.0.31	6379
Slave-1	192.168.0.32	6379
Slave-2	192.168.0.33	6379
Sentinel-1	192.168.0.31	26379
Sentinal-2	192.168.0.32	26379
Sentinel-3	192.168.0.33	26379

 

The overall architecture can be seen in the following image:

The three hosts must be able to communicate with each other. You need to set the binding IP correctly ...
