MySQL 5.7線上設定忽略表複製方法

MySQL5.7版本後增加了線上設定忽略表複製方法，舉例如下:

先停止SQL執行緒:
mysql> STOP SLAVE SQL_THREAD;
Query OK, 0 rows affected (0.01 sec)

mysql> CHANGE REPLICATION FILTER REPLICATE_WILD_IGNORE_TABLE =('credit.%');
Query OK, 0 rows affected (0.00 sec)


mysql> start  SLAVE SQL_THREAD;
Query OK, 0 rows affected (0.01 sec)


mysql> show slave status \G

備註:全部同步所有庫的命令就是:
CHANGE REPLICATION FILTER REPLICATE_DO_DB = ();
只同步部分庫:
CHANGE REPLICATION FILTER REPLICATE_DO_DB = (db1, db2);
