MySQL同步失败解决实例

由于开发的疏忽,把一个库导入到从库里,然后当开发发现导错MySQL数据库服务器,也没向我们运维人员反映,当时查看了主库是没有数据,然后开发又在主库导了,结果同步出错,如下:

mysql> show slave status\G;
*************************** 1. row ***************************
              Slave_IO_State: Waiting for master to send event
                  Master_Host: 192.168.0.155

            Master_Server_Id: 1
1 row in set (0.00 sec)
 
提示:错误信息是无法撤销数据库,数据库不存在。',1008错误
从先创建了这个库,然后主又创建了,至此导致数据库同步冲突

解决方法:
stop slave;
set global sql_slave_skip_counter=1;
start slave;

从库状态:
mysql> show slave status\G;
