Example 5: ubuntu reset mysql root password

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

Stop the MySQL Server: sudo /etc/init.d/mysql stop
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
Run: sudo service mysql start
Login to MySQL as root: mysql -u root mysql
Replace YOURNEWPASSWORD with your new password:

UPDATE
  mysql.user
SET
  Password = PASSWORD('YOURNEWPASSWORD')
WHERE
  User = 'root';
FLUSH PRIVILEGES;
exit;
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.

mysql> USE mysql
mysql> SELECT User, Host, plugin FROM mysql.user;
+------------------+-----------+-----------------------+
| User             | Host      | plugin                |
+------------------+-----------+-----------------------+
| root             | localhost | auth_socket           |
| mysql.session    | localhost | mysql_native_password |
| mysql.sys        | localhost | mysql_native_password |
| debian-sys-maint | localhost | mysql_native_password |
+------------------+-----------+-----------------------+
4 rows in set (0.00 sec)

mysql> UPDATE user SET plugin='mysql_native_password' WHERE User='root';
mysql> COMMIT;  // When you don't have auto-commit switched on
Either:

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_password';
Or:

// For MySQL 5.7+
UPDATE mysql.user SET authentication_string=PASSWORD('new_password') where user='root';
Then:

mysql> FLUSH PRIVILEGES;
mysql> COMMIT;  // When you don't have auto-commit switched on
mysql> EXIT

$ sudo service mysql restart
$ mysql -u root -p
Enter password: // Yay! 'new_password' now works!
