MySQL5.7官方文档关于相关参数的介绍：https://dev.mysql.com/doc/refman/5.7/en/change-replication-filter.html

在5.7版本支持动态修改，之前的版本需要重启数据库：

STOP SLAVE SQL_THREAD;CHANGE REPLICATION FILTER REPLICATE_IGNORE_DB=(demo);START SLAVE SQL_THREAD;

在主库执行语句，如果不使用use db;
创建新表的语句不会在从库执行，进而导致主从错误

从库配置：

replicate-ignore-db = testreplicate-do-db = abc

主库操作：

22:29:04test>use test;Database changed22:30:26test>create table abc.t0417(id int,name varchar(20));Query OK, 0 rows affected (0.08 sec)22:31:37abc>use test;Database changed22:32:05test>insert into abc.t0417 values(1,'a');Query OK, 1 row affected (0.02 sec)

从库状态,SQL线程出现报错：

更改从库配置：

#replicate-ignore-db = test#replicate-do-db = abcreplicate_wild_do_table = abc.%replicate_wild_ignore_table = test.%
