this with a configuration file, you should use the change MASTER to statement, which completely supersedes the modification of the configuration file, and it can specify a different MASTER for slave, without having to stop the server. As follows: mysql> change MASTER to master_host= ' Server1 ', Master_user= ' Repl ', Master_password= ' P4ssword ', Master_log_file= ' mysql-bin.000001 ', master_log_pos=0; T

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 to process all queries for

The advantages of MySQL replication mainly include the following 3 aspects:1. If there is a problem with the primary server, you can quickly switch to services provided from the server2. Can perform query operations from the server, reduce the access pressure on the primary server3. You can perform backups from the server to avoid services that affect the primary server during backup Note: In general, only
