ERROR 1290 (HY000)

ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement.

事件复盘：
之前在mysql中创建了一个库aa@localhost，在删除的时候报错：

mysql> drop user aa@localhost;
ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables
option so it cannot execute this statement

解决：
在删除用户前刷新一下权限；

mysql> flush privileges;
Query OK, 0 rows affected (0.02 sec)

mysql> drop user aa@localhost;
Query OK, 0 rows affected (0.00 sec)
