MySQL创建具有权限的用户自行删除

Question

我需要帮助如何创建一个有可能删除自己的新用户......

CREATE USER 'AdminPS'@'localhost' IDENTIFIED BY PASSWORD  '*CC3DA61A4716581A6A62EE83E5F4119D8C0B5D23';

GRANT ALL ON Database.* TO 'AdminPS'@'localhost';
GRANT DROP USER 'AdminPS'@'localhost' TO 'AdminPS'@'localhost';

Answer 1

您只需要替换最后一行：

CREATE USER 'AdminPS@localhost' IDENTIFIED BY PASSWORD '*CC3DA61A4716581A6A62EE83E5F4119D8C0B5D23';
GRANT ALL ON Database.* TO 'AdminPS@localhost';
GRANT CREATE USER ON *.* TO 'AdminPS@localhost';

Answer 2

正如GRANT Syntax所述：

  

表13.1。 GRANT和REVOKE允许的权限

+-----------------+-------------------------------------------+
|    Privilege    |                  Meaning                  |
+-----------------+-------------------------------------------+
:                 :                                           :
| CREATE USER     | Enable use of CREATE USER, DROP USER,     |
|                 | RENAME USER, and REVOKE ALL PRIVILEGES    |
:                 :                                           :
+-----------------+-------------------------------------------+
:                 :                                           :
| DROP            | Enable databases, tables, and views to be |
|                 | dropped                                   |
:                 :                                           :
+-----------------+-------------------------------------------+

因此，您需要授予CREATE USER权限，而不是DROP。

Answer 3

您需要使用WITH GRANT OPTION创建用户。

e.g.: GRANT ALL ON Database.* TO 'AdminPS'@'localhost' WITH GRANT OPTION;
