One Answer:

First, open your crontab and comment out the line that starts your mysql instance. This is to prevent mysql from starting while you do the rest of the steps.
Stop your MySQL instance.
In your home directory, create a file called "mysql-ini". In that file, add the following two lines:

UPDATE mysql.user SET Password=PASSWORD('<newpassword>') WHERE User='root';

FLUSH PRIVILEGES;

where <newpassword> is the password you want to use.

Start MySQL with the following command:

mysqld_safe --defaults-file=/home/<your_username>/webapps/<name_of_your_mysql_app>/etc/my.cnf --init-file=/home/<your_username>/mysql-init > /dev/null 2>&1 &

This will start MySQL and set the root password.

You should now be able to login as root with your new password.
