大家好，又见面了，我是你们的朋友全栈君。
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.
