The scenarios used in the command mode include: sometimes it is necessary to send a request to some objects, but I don't know who the recipient of the request is or what the operation of the request is. At this time, I hope to design the program code in a loosely coupled way; So that the request sender and the request receiver eliminate the coupling relationship in each other's codes.《最后的丘帕卡布拉斯》由杰西卡·门德斯·西奎罗斯执导。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.A kindergarten teacher's qualification certificate is required.(2) Fire safety assessment agencies can engage in regional fire safety assessment, social unit fire safety assessment, large-scale activity fire safety assessment, special fire design scheme safety assessment and other activities, as well as fire laws and regulations, fire technical standards, fire hazard rectification and other aspects of consulting activities.死了丈夫的高秀兰，领着一女三男四个孩子日子过得十分艰难，几个男孩子又调皮捣乱得让人头疼，想再找个丈夫，可是男人们一看到她的几个孩子，都没人敢招惹。有人介绍了附近工厂的锅炉工老关头。婚后二人感情很深，可是那几个调皮捣蛋的孩子，看到老关对母亲那么好，除了感到不舒服，心里也觉得老关不能把他们怎么样，于是和继父的对立就开始了，一直到死，也没得到和解……
