【问题描述】：

我正在尝试在 mariadb 中添加一个名为 admin 的用户并授予他们来自任何主机的所有权限。

通过检查 mysql.user 中的行，我可以看到添加了用户，在我创建用户后，我看到了 'admin'@'localost' 和 'admin'@'%' 的条目，但是当我尝试执行时赠款，他们没有采取行动；

这是我作为 root 用户所做的事情。

MariaDB [mysql]> CREATE USER 'admin'@'localhost' IDENTIFIED BY 'mypswd';
Query OK, 0 rows affected (0.000 sec)

MariaDB [mysql]> select user, host, password from mysql.user;
+-------+-----------+-------------------------------------------+
| user  | host      | password                                  |
+-------+-----------+-------------------------------------------+
| root  | localhost |                                           |
| root  | 127.0.0.1 |                                           |
| root  | ::1       |                                           |
| admin | localhost | *81C702316842FA904B04F249E80134D93FEDB64C |

为什么我的 GRANT 不起作用？

【解决方案1】：

对不起，我的错。我确实很努力地寻找答案，但我只是发现如果您从 localhost 以 root 身份登录并使用 SHOW GRANTS;它只会向您显示“root”@“localhost”的那些授权。

我需要这样做：

MariaDB [mysql]> SHOW GRANTS FOR 'admin'@'%';
+---------------------------------------------------------------------------------------------------------------+
| Grants for admin@%                                                                                            |
+---------------------------------------------------------------------------------------------------------------+
| GRANT ALL PRIVILEGES ON *.* TO 'admin'@'%' IDENTIFIED BY PASSWORD '*81C702316842FA904B04F249E80134D93FEDB64C' |
+---------------------------------------------------------------------------------------------------------------+
1 row in set (0.000 sec)

MariaDB [mysql]> SHOW GRANTS FOR 'admin'@'localhost';
+-----------------------------------------------------------------------------------------------------------------------+
| Grants for admin@localhost                                                                                            |
+-----------------------------------------------------------------------------------------------------------------------+
| GRANT ALL PRIVILEGES ON *.* TO 'admin'@'localhost' IDENTIFIED BY PASSWORD '*81C702316842FA904B04F249E80134D93FEDB64C' |
+-----------------------------------------------------------------------------------------------------------------------+
1 row in set (0.000 sec)

我不觉得这很直观。
