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: No1.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> stop slave ;mysql> set GLOBAL SQL_SLAVE_SKIP_COUNTER=1;mysql> start slave ;
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> start slave ;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！
