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.大老板天启是作家，神龙见首不见尾，暂且不提。If I set a vague goal and want to improve my English, I will be at a loss when practicing deliberately.There are two main forms of content distribution within the product: scenario and personalization.深夜，大火，奔涌肆虐的地下之火，无情地吞噬着井下的矿工……救护车警笛声声，溪平不眠，溪平煤矿发生了瓦斯爆炸的惨案，但这起惊天大案却不知为什么在社会中竟无声无息、不为人知、没有一丝一毫的披露……某报著名记者迟立强、杨茗莉应邀为溪平煤矿撰写报告文学，职业的敏感使他们捕捉到溪平煤矿所谓先进达标企业的背后，存在违反安全操作规程，暗地里与矿工签定生死合同的不法内幕。而恰在此时，迟立强的前妻俞静在采访北山矿返城的途中突然意外死亡……There are five kinds of creation modes (1-5): factory method mode, abstract factory mode, singleton mode, builder mode and prototype mode.在我们六集的每一集中，Baymax只想帮助某人，但很多时候他们不想得到帮助。他着手解决一个他已经确定的身体问题，在这个过程中，他会进入一个更深、更感性的地方，并且在这个角色上几乎可以改变。
