Gentlemen, I am trying to set up drupal, according to the instructions found here:

if this involves beginning the drupal installation by going to the 127...1/drupal to carry on cellular phone, I'm motivated having a popup either to open or download the PHTML index file.

the finish of my apache2.conf file appears like this:
AddType application/x-compress .Z
AddType application/x-gzip .gz .tgz
AddType application/x-httpd-php .php
AddType application/x-httpd-php .php3
AddType application/x-httpd-php .phtml
AddType application/x-httpd-php-source .phps


unsure it'll help but make certain you reload apache i've discovered with phpmyadmin it sometimes attempts to download the php file as well as an apache reload will repair it.

The instructions you will find strange and includes unnessesary changes towards the config files. I suppose a number of of those changes triggered your apache to interrupt.

All that's necessary, is a straightforward and clean Light (Linux, Apache, MySQL and PHP, which any php-aplication, drupal too, will run) installation. I've discovered howtoforge Lamp for Newbies a helpfull and solid resource for individuals a new comer to Light.

I would recommend your cleanup all of the packages you installed, remove left-over files (apt-get un-install --prune may still leave files yout edited by hand) and begin on your own while using Light instructions from Howtoforge.
