MySQL同步故障(" Slave_SQL_Running:No" 两种解决办法)
故障现象:
进入slave服务器,运行:
mysql> show slave status\G
.......
Relay_Log_File: localhost-relay-bin.000535
Relay_Log_Pos: 21795072
Relay_Master_Log_File: localhost-bin.000094
Slave_IO_Running: Yes
Slave_SQL_Running: No
Replicate_Do_DB:
Replicate_Ignore_DB:
......
解决办法一、
Slave_SQL_Running: No
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.
一般是事务回滚造成的:
解决办法:
mysql> slave stop;
mysql> set GLOBAL SQL_SLAVE_SKIP_COUNTER=1;
mysql> slave start;
【MySQL同步故障(" Slave_SQL_Running:No" 两种解决办法)】解决办法二、
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
进入master
mysql> show master status;
+----------------------+----------+--------------+------------------+
| File| Position | Binlog_Do_DB | Binlog_Ignore_DB |
+----------------------+----------+--------------+------------------+
| localhost-bin.000094 | 33622483 |||
+----------------------+----------+--------------+------------------+
1 row in set (0.00 sec)
然后到slave服务器上执行手动同步:
mysql> change master to
> master_host='master_ip',
> master_user='user',
> master_password='pwd',
> master_port=3306,
> master_log_file=localhost-bin.000094 ',
> master_log_pos=33622483;
1 row in set (0.00 sec)
mysql> slave start;
1 row in set (0.00 sec)
mysql> show slave status\G
*************************** 1. row ***************************
........
Master_Log_File: localhost-bin.000094
Read_Master_Log_Pos: 33768775
Relay_Log_File: localhost-relay-bin.000537
Relay_Log_Pos: 1094034
Relay_Master_Log_File: localhost-bin.000094
Slave_IO_Running: Yes
Slave_SQL_Running: Yes
Replicate_Do_DB:
手动同步需要停止master的写操作!
