ERROR 1044 (42000): Access denied for 'root' With All Privileges

24

I have strange error. I am logged in local Mysql as root via command line. After creating database:

create database some_db;

Then giving privileges to some user:

grant all privileges on some_db.* to [email protected]'localhost' identified by 'password';

This is giving error:

ERROR 1044 (42000): Access denied for user 'root'@'localhost' to database 'some_db'

The permissions for the root(show grants;) shows:

GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY PASSWORD '*8919C53DC7A4DFBF3F8584382E96463583EB7FDA' 

I am also making sure i am logged in as root:

select current_user();

And this confirms that i am logged in as 'root'@'localhost'

I have created database and assigned user multiple times and never had an issue. Why i am unable assign user to the database created by root while logged in as root?

p.s. from other posts, i am thinking the issue may be caused due to some strange users

select host, user from mysql.user;

Some users that i have not added but does show up:

 MY_COMPuTER_name.local |       ''
 MY_COMPuTER_name.local |     root

I tried to delete these users

drop user 'root'@'MY_COMPuTER_name.local';
drop user ''@'MY_COMPuTER_name.local';

However, while it states query run successful, the users are not dropped even after flush privileges. Why i am unable delete users? Any help is much appricated

First, Identify the user you are logged in as:

 select user();
 select current_user();

The result for the first command is what you attempted to login as, the second is what you actually connected as. Confirm that you are logged in as [email protected] in mysql.

Grant_priv to [email protected]. Here is how you can check.

mysql> SELECT host,user,password,Grant_priv,Super_priv FROM mysql.user;
+-----------+------------------+-------------------------------------------+------------+------------+
| host      | user             | password                                  | Grant_priv | Super_priv |
+-----------+------------------+-------------------------------------------+------------+------------+
| localhost | root             | ***************************************** | N          | Y          |
| localhost | debian-sys-maint | ***************************************** | Y          | Y          |
| localhost | staging          | ***************************************** | N          | N          |
+-----------+------------------+-------------------------------------------+------------+------------+

You can see that the Grant_priv is set to N for [email protected] This needs to be Y. Below is how to fixed this:

UPDATE mysql.user SET Grant_priv='Y', Super_priv='Y' WHERE User='root';
FLUSH PRIVILEGES;
GRANT ALL ON *.* TO 'root'@'localhost';

I logged back in, it was fine.

If you get an error 1044 (42000) when you try to run SQL commands in MySQL (which installed along XAMPP server) cmd prompt, then here's the solution:

  1. Close your MySQL command prompt.

  2. Open your cmd prompt (from Start menu -> run -> cmd) which will show: C:\Users\User>_

  3. Go to MySQL.exe by Typing the following commands:

C:\Users\User>cd\ C:\>cd xampp C:\xampp>cd mysql C:\xxampp\mysql>cd bin C:\xampp\mysql\bin>mysql -u root

  1. Now try creating a new database by typing:

    mysql> create database employee;
    

    if it shows:

    Query OK, 1 row affected (0.00 sec)
    mysql>
    

    Then congrats ! You are good to go...
