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
                  Master_User: mysync
                  Master_Port: 2503306
                Connect_Retry: 60
              Master_Log_File: mysql-bin.000005
          Read_Master_Log_Pos: 3711
               Relay_Log_File:
HE1-relay-bin.000007
                Relay_Log_Pos: 484
        Relay_Master_Log_File: mysql-bin.000005
             Slave_IO_Running: Yes
            Slave_SQL_Running: Yes

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
Warnings: 0

mysql> select * from helei;
+----+------+
| id | text |
+----+------+
|  1 | aa
|
|  2 | bb
|
|  3 | ccc
|
|  4 | ee
|
|  5 | ff
|
|  6 | gg
|
|  7 | hh
|
+----+------+
7 rows in set (0.00
sec)

HE1从库报错

mysql> show slave status\G;

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。

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)

mysql> select * from helei;

mysql> show slave status\G;

               Slave_IO_State: Waiting for

                  Master_Host: 192.168.1.250
                  Master_User: mysync
                  Master_Port: 2503306

             Slave_IO_Running: Yes
            Slave_SQL_Running: Yes

这里虽然通过跳过错误达到恢复主从同步，但如果主库又对该条记录更新

mysql> show slave status\G;
