在配置mysql主从同步的时候遇到了查看从服务器状态显示为:
Slave_SQL_Running:No

搜索通过以下第一种方法解决.主服务器已有数据,而从服务器因为当时配置的数据库版本不一致导致没法同步,后安装同一数据库版本后,运行状态为Slave_SQL_Running:No

以下为转贴:

故障状态:
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;



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!
