MySQL的：授予用户拒绝命令

Question

I need help regarding mysql grant command. I need to grant select command on a table to a user which is from different host.

GRANT SELECT on db.table TO user@xx.xx.xxx AT password (xx.xx.xxx is ip address of other server and user is username at that server)

The above statement is giving me error:

1174 - Grant command denied to user

It is working fine in the localhost phpmyadmin. But when I do it in cpanel phpmyadmin it gives error.

Thanks

Answer 1

To answer your question, you simply don't have the GRANT OPTION privilege.

You might have grant privileges in localhost but you certainly don't on your cpanel (live server)

The GRANT statement grants privileges to MySQL user accounts. To use GRANT, you must.

• Have the GRANT OPTION privilege,
• And you must have the privileges that you are granting.

Also:

The GRANT OPTION privilege enables users to give their privileges to other users. Two users that have different privileges and with the GRANT OPTION privilege are able to combine privileges.

As with most hosts, When they create your account, a mysql account/user is also automatically generated to go along with it, and its (usually) given a database privilege . Therefore, the privileges they give you / that comes with your account are all you have. So if you are the admin of your account and you dont have the grant option privilege, you wont be able to use it.

Answer 2

Well you don't need the AT password

Here is the example from the MySQL docu:

GRANT SELECT ON db2.invoice TO 'jeffrey'@'localhost';

The password should be handled at your CREATE USER statement.

Please try it this way. Does your own user which runs the GRANT -statement has the right to give rights? Is it an admin user?

Answer 3

Try This
Add skip-grant-tables in my.cnf file under the [mysqld] section or otherwise stop mysqld and start it with the --skip-grant-tables option.

Use mysql to connect to DB without password without -p

Then execute this:

UPDATE mysql.user SET Grant_priv='Y', Super_priv='Y' WHERE User='root';
FLUSH PRIVILEGES;

Then execute: GRANT ALL ON *.* TO 'root'@'localhost';
