mysql主从同步出现异常语句跳过错误处理

1.跳过操作：

mysql>slave stop;

mysql>SET GLOBAL SQL_SLAVE_SKIP_COUNTER = 1 跳过一个事务

mysql>slave start

2.SET GLOBAL SQL_SLAVE_SKIP_COUNTER = 1，跳过一个事务的概念。

在mysql中，对于sql的 binary log 他实际上是由一连串的event组成的一个组，即事务组。

我们在master上可以通过

SHOW BINLOG EVENTS 来查看一个sql里有多少个event。

例如：

mysql> SHOW BINLOG EVENTS in 'mysql-bin.000003' from 9508\G

*************************** 1. row ***************************一个row代表一个事务组

Log_name: mysql-bin.000003

Server_id: 2

End_log_pos: 9944

Info: use `BK`; CREATE DEFINER=`root`@`%` PROCEDURE `zoucm`( in Spwd VARCHAR(20), in Npwd varchar(20), in YH VARCHAR(20))

pwd_s:

BEGIN

DECLARE Pid int;

select count(*) into Pid from users where user = YH and PWD = Spwd;

if Pid=1 THEN

update users set PWD=Npwd where user = YH and PWD = Spwd;

select 0 state ;

LEAVE pwd_s;

ELSE

select 1 as state ;

end if;

end pwd_s

*************************** 2. row ***************************

Log_name: mysql-bin.000003

Pos: 9944

Event_type: Query

Server_id: 2

End_log_pos: 10080

Info: use `liguanjia_cn`; CREATE TABLE `sss` (

*************************** 3. row ***************************

Log_name: mysql-bin.000003

Pos: 10080

Event_type: Query

Server_id: 2

End_log_pos: 10214

Info: use `liguanjia_cn`; CREATE TABLE `dd` (

)

master从出错开始binlog日志事务组列表：

End_log_pos:14413

Info: use `liguanjia_cn`;UPDATE `dd` SET `ss`='123' WHERE (`ss`='0')

4 rows in set (0.00 sec)

操作目标：

"drop procedure zoucm " 该语句是出错源头。

如果我们想直接跳到 “UPDATE `dd` SET `ss`='123' WHERE (`ss`='0')” 改语句，它们之间隔着3个事务组。

mysql>SET GLOBAL SQL_SLAVE_SKIP_COUNTER = 3 就之间从“UPDATE `dd` SET `ss`='123' WHERE (`ss`='0')该语句开始同步
