Slave_SQL_Running:No的两种解决办法
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> stop slave ; mysql> set GLOBAL SQL_SLAVE_SKIP_COUNTER=1; mysql> start slave ;
解决办法二、(推荐)
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)
start slave
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:
CHANGE MASTER TO master_host = 'xx.xx.xx.xx',
master_port = 3306,
master_user = 'xxx_slave',
master_password = 'xxx',
master_log_file = 'mysql-bin.000574',
master_log_pos = 48665419;
