It doesn't appear that mysql is running. Did you install the initial database? If not, the very first thing you should do is run:
su - mysql
Then you should change the permissions on /etc/rc.d/rc.mysqld so that it's started automatically upon boot, assuming that's what you want. You can do that with:
chmod 755 /etc/rc.d/rc.mysqld
Then start the server like this:
Then try to reset your password again.
