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.连你也帮不了——男人的宠爱是不会长久的，别看你现在放不下她。《老广的味道》以独特视角深入广东美食腹地追根溯源，挖掘原汁原味的美食美景，体现特色全粤菜谱。上山下海，探索南粤大地深藏的最高食鲜；味蕾冒险，展现岭南就地取材的生存智慧；依天而食，回归老广时令节气的饮食法则；原声原味，搜寻天间特色环境的自然之味。大道至简，还原广东乡野厨艺的朴素之心；以食养生，揭示南方天地元气的滋养之谜。自己只要成功缠住了这些暗地里的护卫，也算是参与其中，和自己动手差别不多。People who join the IT industry are extremely intelligent, interested, creative, pragmatic and ambitious, with incomparable creativity, life and clear action goals.
