1. IntroductionAs one of the most widely used databases in the world, MySQL is one of the reasons why it is free. But what is not to be overlooked is that its own function is indeed very powerful. With the development of technology, in the actual production environment, the single MySQL database server can not meet the actual demand. At this point the database cluster is a good solution to this problem. With MySQL distributed cluster, you can build a high-concurrency, load-balanced cluster Serve

Http://blog.csdn.net/wtyvhreal/article/details/42916503 Through the persistence function, Redis ensures that no (or a small amount of) data is lost even when the server is restarted. However, because the data is stored on a server, if the hard disk of the server fa
