MYSQL同步 Slave_IO_Running: No 或者Slave_SQL_Running: No 解决办法

今天在测试新的搜索技术时,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 status\G
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

2.到主服务器上查看主机状态:
记录File和Position对应的值。
mysql> show master status;
+------------------+-----------+--------------+------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+-----------+--------------+------------------+
| mysql-bin.000020 | 135617781 | | |
+------------------+-----------+--------------+------------------+
1 row in set (0.00 sec)

3.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=3307, 
> master_log_file='mysql-bin.000020', 
> master_log_pos=135617781;
1 row in set (0.00 sec)

#我执行的sql

mysql> change master to   master_host='192.168.10.14',  master_user='repl',  master_password='repl', master_port=3306,  master_log_file='mysql-bin.000006',  master_log_pos=98;


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;
