mysql主從同步出現異常語句跳過錯誤處理

1.跳過操做：

mysql>slave stop;

mysql>SET GLOBAL SQL_SLAVE_SKIP_COUNTER = 1        跳過一個事務

mysql>slave start

2.SET GLOBAL SQL_SLAVE_SKIP_COUNTER = 1，跳過一個事務的概念。

 在mysql中，對於sql的 binary log 他其實是由一連串的event組成的一個組，即事務組。
咱們在master上能夠經過
SHOW BINLOG EVENTS 來查看一個sql裏有多少個event。

 例如：

mysql> SHOW BINLOG EVENTS in 'mysql-bin.000003' from 9508\G
*************************** 1. row ***************************                                                     一個row表明一個事務組
Log_name: mysql-bin.000003
Pos: 9508
Event_type: Query
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` (
`ds` int(11) NULL ,
PRIMARY KEY (`ds`)
)
*************************** 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` (
`ss` double NULL ,
PRIMARY KEY (`ss`)
)

3。實例出錯解決：

slave出錯信息：

 

mysql> show slave status\G

master從出錯開始binlog日誌事務組列表：

 

mysql> SHOW BINLOG EVENTS in 'mysql-bin.000003' from 13973\G
*************************** 1. row ***************************
Log_name: mysql-bin.000003
Pos: 13973
Event_type: Query
Server_id: 2
End_log_pos: 14054
Info: use `BK`; drop procedure zoucm
*************************** 2. row ***************************
Log_name: mysql-bin.000003
Pos: 14054
Event_type: Query
Server_id: 2
End_log_pos: 14162
Info: use `liguanjia_cn`; INSERT INTO `dd` (`ss`) VALUES ('dd')
*************************** 3. row ***************************
Log_name: mysql-bin.000003
Pos: 14162
Event_type: Query
Server_id: 2
End_log_pos: 14299
Info: use `liguanjia_cn`; ALTER TABLE `dd`
MODIFY COLUMN `ss` int NOT NULL DEFAULT 0 FIRST
*************************** 4. row ***************************
Log_name: mysql-bin.000003
Pos: 14299
Event_type: Query
Server_id: 2
End_log_pos: 14413
Info: use `liguanjia_cn`; UPDATE `dd` SET `ss`='123' WHERE (`ss`='0')
4 rows in set (0.00 sec)

 

操做目標：

"drop procedure zoucm " 該語句是出錯源頭。

若是咱們想直接跳到 「UPDATE `dd` SET `ss`='123' WHERE (`ss`='0')」  改語句，它們之間隔着3個事務組。

mysql>SET GLOBAL SQL_SLAVE_SKIP_COUNTER = 3 就之間從「UPDATE `dd` SET `ss`='123' WHERE (`ss`='0')該語句開始同步
