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.Disadvantages: There are a little more node objects in the responsibility chain mode. It is possible that most nodes do not play a substantial role in a certain request process. Their role is only to make如今沛公在关中百姓心中，是仁义慈爱的象征，若是这时候杀了子婴，秦国百姓便会心中仇恨，行为抗拒，关中民心尽失，之前苦心经营的一切将会付之东流。Qu Goblin: He will learn and keep reading habits at critical moments (although it is related to purchase, it is also the absorption of popular trend information);心头一片空灵，连回乡的诸般温馨和定亲的喜悦都沉淀在心底，耳边只听得庙后豆腐房里传来磨拐子咿咿呀呀拉扯的声音和石磨呼呼转动声。The packaging is quite simple, not much different from most products, simple transparent plastic bags.尹旭叹道：一来是不愿意见到英雄死后还要受人欺凌，二来，他们对越国大有作用。
