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 root password reset

Update: On 8.0.15 (maybe already before that version) the PASSWORD() function does not work You have to do:

Make sure you have Stopped MySQL first (above).
Run the server in safe mode with privilege bypass: sudo mysqld_safe --skip-grant-tables
mysql -u root
UPDATE mysql.user SET authentication_string=null WHERE User='root';
FLUSH PRIVILEGES;
exit;
Then
mysql -u root
ALTER USER 'root'@'localhost' IDENTIFIED WITH caching_sha2_password BY 'yourpasswd';
