replicate-wild-ignore-table=test2.% 那么：主库上的只有test的操作会同步至从库，test2和其它的库都不会同步，新建db 也不会同步 2.只有replicate-wild-ignore-table replicate-wild-ignore-table= liuliang.% 那么：主库上只有liuliang库的操作不同步，其它的都同步，并且新建库也会同步！ 3.只有replicate-wild-do-table replicate-wild-do-table=oauth.% 那么：主库上只有oauth的操作才同步，其它的都不同步，新建的db也不会同步 ===等同于第一种模式！ 再备份一个 [client] port = 3306 socket = /data/3306/mysql.sock default-character-set=utf8mb4
