MySQL 用户和所有权限

好的，我正在尝试将用户添加到 MySQL 数据库。该用户应该能够将其他用户添加到其拥有权限的数据库中。所以我这样做了：

GRANT ALL privileges ON thedbname.* TO 'topuser'@'%' IDENTIFIED BY 'pass';

但是，我这个用户无法添加用户。这是因为我只为单个数据库提供了“全部”吗？当我查看权限时，权限显示为“N”，而如果删除数据库名称，权限将显示为“Y”。

我希望“topuser”能够运行这个：

GRANT SELECT ON thedbname.* TO 'seconduser'@'%' IDENTIFIED BY 'pass';

他们不需要将用户添加到其他数据库，因此我在这里尝试。

这是一个 Web 应用程序，用户提供用户名和密码来访问数据库，这样密码就不会存储在代码中。欢迎其他解决方案！

Ok, I'm trying to add a user to a MySQL database. This user should be able to add other users to the database it has privileges for. So I did this:

GRANT ALL privileges ON thedbname.* TO 'topuser'@'%' IDENTIFIED BY 'pass';

However, I this user cannot add users. Is that because I only gave them 'all' for a single database? The permissions show up as 'N' when I view them whereas if I remove the database name they show as 'Y'.

I want 'topuser' to be able to run this:

GRANT SELECT ON thedbname.* TO 'seconduser'@'%' IDENTIFIED BY 'pass';

They do not need to add users to other databases, hence my attempts here.

This is for a web app where users provide a username and password to access a database so that a password is not stored in the code. Other solutions welcomed though!

您必须授予“授予其他特权”。 GRANT 手册可在此处获取。

MySQL 仅在 ALL 中包含基本权限，如果你仔细查看文档，它会说全部是：

Grant all privileges at specified access level except GRANT OPTION

所以你应该向你的顶级用户授予“授予选项”：

GRANT GRANT OPTION ON thedbname.* TO 'topuser'@'%' IDENTIFIED BY 'pass';

You have to GRANT the "grant to other privilege". The manual of the GRANT is available here.

MySQL to include only basic privileges in the ALL, if you take a close look at the documentation it says all is :

Grant all privileges at specified access level except GRANT OPTION

so you should grant the "grant option" to your top user :

GRANT GRANT OPTION ON thedbname.* TO 'topuser'@'%' IDENTIFIED BY 'pass';
