In Soundbreak, we play live audio and video continuously 24 hours a day, so we cannot make a convincing test of the new replication feature of MySQL. Through tests, we found that this feature can be used to maintain data synchronization with the backup database server, so that when the master server fails to process for some reason, it can use the backup machine

MySQL is an open source relational database system. Replication (Replication) is a process that replicates data from a MySQL database server (master server master) to another server (slave from the server). Configure Primary server (Master)1, edit the database configuration file my.cnf, generally in the/etc/directory.
