In MySQL 5.55.6, set synchronous replication filtering. For example, to ignore the t2 table of the test database, you need. added in the cnf configuration file: The replicate-ignore-tabletest.t2 must restart the mysql service process to take effect. In MySQL5.7, a new command can be used to support dynamic online modification without restarting the mysql process. In MySQL 5.6/, set
