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;

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';
