    If you check the mysql website and do a search, you'll find this:

      In a Unix environment, the procedure for resetting the root password
    is as follows:

        1.

           Log on to your system as either the Unix root user or as the same
    user that the mysqld server runs as.
        2.

           Locate the .pid file that contains the server's process ID. The
    exact location and name of this file depend on your distribution,
    hostname, and configuration. Common locations are /var/lib/mysql/,
    /var/run/mysqld/, and /usr/local/mysql/data/. Generally, the filename
    has the extension of .pid and begins with either mysqld or your system's
    hostname.

           You can stop the MySQL server by sending a normal kill (not kill
    -9) to the mysqld process, using the pathname of the .pid file in the
    following command:

    shell> kill `cat /mysql-data-directory/host_name.pid`

           Note the use of backticks rather than forward quotes with the cat
    command; these cause the output of cat to be substituted into the kill
    command.
        3.

           Create a text file and place the following command within it on a
    single line:

    SET PASSWORD FOR 'root'@'localhost' = PASSWORD('MyNewPassword');

           Save the file with any name. For this example the file will be
    ~/mysql-init.
        4.

           Restart the MySQL server with the special
    --init-file=~/mysql-init option:

    shell> mysqld_safe --init-file=~/mysql-init &

           The contents of the init-file are executed at server startup,
    changing the root password. After the server has started successfully
    you should delete ~/mysql-init.
        5.

           You should be able to connect using the new password.
