My task is simple i want to create a user in MySQL server that has all the privileges but excluding the ability to create other users.

I tried to create a user through the root account. then i gave him all the privileges, then i revoked the 'create user' privilege from this new user, then i 'flushed privileges'. i thought this is would be enough but when i logged in with the new user, i was able to create another user.

these are the codes that i used in my root account to create a new user and give him privileges except for the 'create user' privilege:

     create user 'user91'@'localhost' identified by 'google';
     grant all privileges on *.* to 'user91'@'localhost';
     revoke create user on *.* from 'user91'@'localhost';
     flush privileges;

After this i logged out of the root account and signed in with the 'user91' account and tried to create another user with this code:

     create user 'slim2000'@'localhost' identified by 'stealth';

and this code worked, what should i add in the first block of code in order to prevent 'user91' from creating other users.

  • Hi @mohamed - do a SHOW GRANTS FOR 'slim2000'@'localhost'; you should have only USAGE - which means that the user can only login and not connect to any schemas. It's puzzling - I'm afraid I don't have time to check it out tonight - I'll look tomorrow. Motto of the story - only give the grants that you know they'll need - no need to REVOKE then.

This works:

As root:

mysql> CREATE USER 'myuser'@'%' IDENTIFIED BY 'billy';
Query OK, 0 rows affected (0.04 sec)

Then, on the sport schema, grant ALL to myuser

mysql> GRANT ALL ON sport.* TO 'myuser'@'%';
Query OK, 0 rows affected (0.02 sec)

Exit and then log on as the new user myuser

mysql> exit;
[pol@localhost inst]$ ./bin/mysql -S ./mysql.sock -u myuser -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 5
Server version: 5.6.22-log Source distribution

Show all the schemas myuser can see

mysql> show schemas;
| Database           |
| information_schema |
| sport              |
| test               |
3 rows in set (0.00 sec)

There are many more schemas on this server - it's just that myuser can't see them.

mysql> use sport;
Database changed

Then, try to create a user as myuser.

mysql> create user 'fred'@'%' IDENTIFIED BY 'mary';
ERROR 1227 (42000): Access denied; you need (at least one of) the CREATE USER privilege(s) for this operation


But, I can do this.

mysql> create table test (a int, b varchar(10));
Query OK, 0 rows affected (0.53 sec)

mysql> insert into test values(3, 'testvalue');
Query OK, 1 row affected (0.04 sec)

Take a look at the three answers here, here and here for a better idea of what's going on. Always test your users after creation - it's very easy to give users too much power.

You can also do it this way (a more elegant solution perhaps)

ON sport.* TO 'username'@'localhost' IDENTIFIED BY 'password';

Finally, you could just remove the CREATE USER privilege (and, of course, the WITH GRANT OPTION) from this answer to have a "super user" who can do everything except create new users.

I think @sqlbot may have figured out the root of your problem.

  • thank you for this great answer, i would to share with you my code so that you can tell me what i did wrong:

  • thank you for this great answer, i would to share with you my code so that you can tell me what i did wrong: first i created a user just as you did, then i granted his privileges by saying (grant all privileges on . to 'user91'@'localhost' identified by 'google';) then i revoked the create user privilege by (revoke create user on . from 'user91'@'localhost';) and then (flush privileges;). with this i was still able to create a new user with 'user91' but unable to grant any privileges. did i miss anything?

  • i dont know why the codes aren't showing properly in this comment but when i said 'grant all privileges on...' then there are two stars and a dot in the middle. and the same goes for the rest of the codes

  • Sometimes Markdown can change/swallow characters like asterisks, greater than/less than and others. Better maybe to edit your question and let me know by leaving a comment with @Vérace - note the accent over the e!
