Data from one master library can be synchronized to multiple repositories, and the repository itself can be configured as the main repository for other servers.Main applications:1) Data distribution2) Load Balancing3) Pseudo backup. Add more secure technical supplements based on backup4) High availability and failover. Avoid MySQL single point of failure5) Upgrade test. Before upgrading

MyIsam is relatively simple to publish, just copy all the files in the library. The procedure of copying Innodb is similar to that of MyIsam, except that the table content in the Innodb Engine no longer exists in the same database directory (MyIsam does this). In the Innodb engine, data files are stored in files such as ibdata1, and operation logs are stored in files such as ib_logfile0, ib_logfile1, and ib_logfile2 by default.Innodb replication and p
