Both MySQL and MariaDB is an open source database management system. In this quick tutorial, you will learn how to delete ore remove user account in MySQL or MariaDB database on Linux or Unix-like system.

How to delete or remove a MySQL/MariaDB user account

You must login as root user account on your MySQL or MariaDB server to delete user account. Let us see all steps in details.

Warning: Backup your database before you type any one of the following command.

Step 1 – Steps for removing a MySQL/MariaDB user

If you decided to remove open source application such as WordPress or Drupal you need to remove that user account. You need to remove all permissions/grants, and delete the user from the MySQL table. First, login as mysql root user to the MySQL/MariaDB server using the shell, run:
$ mysql -u root -p mysql
$ mysql -u root -h server-name-here -p mysql
Sample outputs:

mariadb> SELECT User,Host FROM mysql.user;
Sample outputs:

In this above example, I need to delete a mysql user named ‘bloguser’@’localhost’.

To see what grants bloguser have, enter:
mariadb> SHOW GRANTS FOR 'bloguser'@'localhost';
Sample outputs:

  2. localhost – Mysql/Mariadb host name
  3. mywpblog – Database name

Step 4 – Revoke all grants for a mysql user

Type the following sql command:
mariadb> REVOKE ALL PRIVILEGES, GRANT OPTION FROM 'bloguser'@'localhost';
Sample outputs:

Query OK, 0 rows affected (0.00 sec)

Step 5 – Remove/Delete the user from the user table

Type the following sql command:
mariadb> DROP USER 'bloguser'@'localhost';
Sample outputs:

Query OK, 0 rows affected (0.00 sec)

Step 6 – Delete the database

Type the following command:
mariadb> DROP DATABASE mywpblog;
Sample outputs:

Query OK, 0 rows affected (0.00 sec)

And there you have it. A MySQL/MariaDB user deleted or removed from the server on Unix or Linux via command line option.

A note about DROP USER sql command to delete or remove a MySQL/MariaDB user account

The DROP USER statement removes one or more MariaDB accounts. It removes privilege rows for the account from all grant tables. To use this statement, you must have the global CREATE USER privilege or the DELETE privilege for the mysql database. The syntax is:
mariadb> DROP USER foo;
mariadb> DROP USER IF EXISTS bar;

    Using “mysql -u root -p mysql” in the commandline is a realy bad idea, the plain password will be visible in the history! just use “-p” without the password, will avoid this and asks for the password.

      That is not a password. mysql is database name. For password syntax is:
      mysql -u root -p'password' mysql

        Doh! Sorry, my fault – didn’t realize the space

    `Step 5 Delete the database`
    Step 5 is duplicate. You mean ‘Step 6’ ;)

    ‘mariadb> DROP DATABASE mywpblog;;’

    ‘;;’ – should be one ‘;’
