在兼职DBA的工作中，由于同事在数据库上误操作，导致数据库同步停止，情况如下：
mysql>show slave status\G; *************************** 1. row*************************** Slave_IO_State: Waiting formaster to send event Master_Host: 172.16.1.2 Master_User: rep Master_Port: 3306 Connect_Retry: 60 Master_Log_File: mysql-bin.000003 Read_Master_Log_Pos: 641 Relay_Log_File:mysqld-relay-bin.000004 Relay_Log_Pos: 251 Relay_Master_Log_File: mysql-bin.000003 Slave_IO_Running:Yes Slave_SQL_Running: No #同步不成功 Replicate_Do_DB: Replicate_Ignore_DB: Replicate_Do_Table: Replicate_Ignore_Table: Replicate_Wild_Do_Table: Replicate_Wild_Ignore_Table: Last_Errno: 1007 Last_Error: Error ‘Can‘tcreate database ‘butongbu‘; database exists‘ on query.

Default database: ‘butongbu‘.Query: ‘create database butongbu‘ 1 row in set (0.00 sec)
根据仔细分析，解决办法如下：
stopslave;
setglobal sql_slave_skip_counter=1;
startslave;
