The answer is

Set / change / reset the MySQL root password on Ubuntu Linux. Enter the following lines in your terminal.

  1. Stop the MySQL Server: sudo /etc/init.d/mysql stop
  2. Start the mysqld configuration: sudo mysqld --skip-grant-tables &

    In some cases, you've to create the /var/run/mysqld first:

    sudo mkdir -v /var/run/mysqld && sudo chown mysql /var/run/mysqld
  3. Run: sudo service mysql start
  4. Login to MySQL as root: mysql -u root mysql
  5. Replace YOURNEWPASSWORD with your new password:

      User = 'root';

Note: on some versions, if password column doesn't exist, you may want to try:
UPDATE user SET authentication_string=password('YOURNEWPASSWORD') WHERE user='root';

Note: This method is not regarded as the most secure way of resetting the password, however, it works.
