Got error: 1449: The user specified as a definer ('root'@'%') does not exist

mysqldump: Got error: 1449: The user specified as a definer ('root'@'%') does not exist when using LOCK TABLES

只要给root用户再添加一个对全部host都有可以访问的权限
操作如下：
登陆mysql
mysql -u root -pPasswd
mysql >grant all privileges on *.* to root@"%" identified by "Passwd"
mysql >flush privileges;
==============
END~! KO.
再进行导出就可以执行了。
