mysql同步的时候出现Slave_SQL_Running No错误的解决思路

今天检查数据库发现一台MySQL Slave未和主机同步,查看Slave状态:

mysql> show slave statusG

Slave_IO_Running: Yes

Slave_SQL_Running: No

Last_Errno: 1062

....

Seconds_Behind_Master:NULL

原因:

1.程序可能在slave上进行了写操作

2.也可能是slave机器重起后,事务回滚造成的.

解决办法I:

1.首先停掉Slave服务:slave stop

到主服务器上查看主机状态:

记录File和Position对应的值。

3.到slave服务器上执行手动同步:

mysql> show master status;

+------------------+-----------+--------------+------------------+

| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |

+------------------+-----------+--------------+------------------+

| mysql-bin.000020 | 135617781 | | |

+------------------+-----------+--------------+------------------+

1 row in set (0.00 sec)

mysql> change master to

> master_host='master_ip',

> master_user='user',

> master_password='pwd',

> master_port=3307,

> master_log_file='mysql-bin.000020',

> master_log_pos=135617781;

1 row in set (0.00 sec)

mysql> slave start;

1 row in set (0.00 sec)

再次查看slave状态发现:

Slave_IO_Running: Yes

Slave_SQL_Running: Yes

...

Seconds_Behind_Master: 0

解决办法II:

mysql> slave stop;

mysql> set GLOBAL SQL_SLAVE_SKIP_COUNTER=1;

mysql> slave start;
