mysql复制过滤参数说明

参考文档:
 
总共有6个过滤规则:
1  --replicate-do-db
2  --replicate-ignore-db
3  --replicate-do-table
4  --replicate-wild-do-table
5  --replicate-ignore-table
6  --replicate-wild-ignore-table
 
以上6个规则的前2个是库级别的规则,后4个是表级别的规则。使用注意点:
1:库级别的规则,只针对binlog_format='STATEMENT'或'MIXED'。
2:如果是binlog_format='ROW',不受库级别规则限制,只受表级别规则限制。
3:表级别的规则,针对所有模式。
4:binlog_format='STATEMENT'或者'MIXED'时,记录use 语句,此时如果使用 --replicate-do-db,则不支持跨库修改。
    如use test; update db1 set …… 这里判断的是use 后面的test库,所以updte语句不执行。建议使用--replicate-wild-do-table
5:binlog_format='ROW'时,不记录use语句。只受表级别规则的影响。只能配置后面四条规则。
 
测试不同模式下binlog记录情况:
 
执行sql:
set global binlog_format='row';
use test;
update db1.t2 set name='a200' where id=105;
use db1;
 
记录的binlog如下:
 1 /*!50530 SET @@SESSION.PSEUDO_SLAVE_MODE=1*/;
 2 /*!40019 SET @@session.max_insert_delayed_threads=0*/;
 3 /*!50003 SET @OLD_COMPLETION_TYPE=@@COMPLETION_TYPE,COMPLETION_TYPE=0*/;
