3分钟解决MySQL 1032主从错误
Part1:写在最前
1032错误----现在生产库中好多数据,在从库误删了,生产库更新后找不到了,现在主从不同步了,再跳过错误也没用,因为没这条,再更新还会报错
解决方案
Part1:临时方案
mysql> stop slave;
Query OK, 0 rows
affected (0.00 sec)
mysql> set global sql_slave_skip_counter=1;
Query OK, 0 rows
affected (0.00 sec)
mysql> start slave;
Query OK, 0 rows
affected (0.00 sec)
Part2:永久方案
end_log_pos 有了它,根据pos值,直接就能找到,找到delete那条数据,反做(变成insert)
故障模拟
HE1从库误删
mysql> delete from helei where id=3;
Query OK, 1 row
affected (0.29 sec)
mysql> select * from helei;
+----+------+
| id | text |
+----+------+
| 1 | aa
|
| 2 | bb
|
| 4 | ee
|
| 5 | ff
|
| 6 | gg
|
| 7 | hh
|
+----+------+
6 rows in set (0.00
sec)
mysql> show slave status\G;
***************************
1. row ***************************
Slave_IO_State: Waiting for
master to send event
Master_Host: 192.168.1.250

Relay_Log_Pos: 484
Relay_Master_Log_File: mysql-bin.000005

此时从库状态是正常的,但一旦主库对该条记录进行操作
HE3主库更新从库刚刚误删的数据
mysql> update helei set text='ccc' where id=3;
Query OK, 1 row
affected (0.01 sec)
Rows matched: 1 Changed: 1

mysql> select * from helei;

此时主从又不同步了,如果还去执行跳过错误操作,主从恢复同步,而且状态均为yes,但!这并不能解决该问题,如果主库又更新该条记录,那么还是会报相同错误,而且pos号还会变,这就导致了恢复时你不知道前一条的pos号,导致丢失数据。
