In the last article, we explained Redis' master-slave cluster mode in detail. 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.三位闺蜜即将迈入40 岁的门槛，她们相互扶持，风雨同舟，共同面对生活、爱和失去。Step 4: Final Implementation Means2951动画主要讲述的是王志哲是电脑权威王博士之子。一天晚上，他和老爸誓要“爆机”，而妈妈如往常一样对这这对无所事事的父子大发雷霆。这时，王博士大学时的好友达克浑身是血登门拜访。正在全家人诧异时，闯进来一只紫色狼人！达克也化身成蓝色狼人，并打败了紫色狼人。Source: Baidu Encyclopedia-Teacher Qualification Certificate他心中一软，俯身抱起她，道：走累了？哥哥抱着你。
