ERROR:

解决办法：
从机器停止slave
mysql> slave stop;
到master机器登陆mysql：
记录master的bin的位置，例如：mysql> show mster status;

+——————+———-+————–+——————+
| File             | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+——————+———-+————–+——————+
| mysql-bin.000013 |      107 | discuz       |                  |
+——————+———-+————–+——————+
1 row in set (0.00 sec)

日志为mysqld-bin.000013
刷新日志：mysql> flush logs;
因为刷新日志file的位置会+1，即File变成为:mysqld-bin.000014
马上到slave server执行
mysql> CHANGE MASTER TO MASTER_LOG_FILE=’mysqld-bin.000014′,MASTER_LOG_POS=107;
mysql> slave start;
mysql> show slave status\G;
主从恢复正常

注：CHANGE MASTER TO MASTER_LOG_FILE=’mysqld-bin.000014′,MASTER_LOG_POS=107;语句千万注意单引号前面不能有空格，否则也会主从同步失败,关闭selinux和iptables允许master、slave伺服器的ip访问.
