mysql-创建用户报错ERROR 1396 (HY000): Operation CREATE USER failed for 'XXXX'@'XXXX'

创建用户：

create user ‘test’@’%’ identified by ‘test’;

显示ERROR 1396 (HY000): Operation CREATE USER failed for ‘test’@’%’

查看是不是存在这个用户

select user from user;

发现没有这个用户。

记得上次有删除过这个用户。可能没有刷新权限

flush privileges;

之后还是不行报错ERROR 1396 (HY000): Operation CREATE USER failed for ‘test’@’%’

没办法再删除一次：

drop user ‘test’@’%’;

flush privileges;

之后create user ‘test’@’%’ identified by ‘test’;

成功。

网上找了下原因：

Assume the user is there, so drop the user

After deleting the user, there is need to flush the mysql privileges

Now create the user.
