解决mysql slave同步问题

解决办法：
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;
4.启动slave
slave start;
5.查看slave状态
show slave status \G;
