In fact, the configuration of this cluster mode is very simple. It only needs to be configured on Slave's nodes. The configuration of Master's master node does not need to be changed. However, one thing is that the persistent configuration of Master and Slave nodes should be consistent as far as possible, otherwise there will be strange problems. Starting today, we will begin to talk about the second mode of Redis cluster mode. That is, the "Sentinel" mode, which was provided from version 2.6 of Redis, but the mode of this version was unstable at that time. The Sentinel mode did not stabilize until version 2.8 of Redis. In the production environment, if you want to use the Sentinel mode of Redis, you will try to use the version after version 2.8 of Redis. Whether it is master-slave mode or sentinel mode, both modes have a problem and cannot be expanded horizontally, and the high availability of these two modes will be limited by the memory of Master master node. Another point is that the configuration of Sentinel mode is not simple or even complicated, so neither mode is recommended in industrial scenes. If you want to use it, you must have solutions to related problems to avoid subsequent problems.
