How to dislodge drupal from Apache and remove drupal Excuse me please.. I am new to website development. I am using LAMP on fedora 20.
I am also using bluefish to edit html/php.

As a shear experiment, I installed Commerce Kickstart on my system. I did some terrible mistakes and now I need to remove drupal completely from the system..

I was just thinking of deleting the files and dropping the database. but is it enough? 

thanks in advance
Yes, deleting the files and dropping the database should be enough.

If you made any changes to Apache (eg. creating a virtual host) and/or the operating system (eg. a line in the /etc/hosts file) you may want to revert that as well.

Don't worry about messing it up the first time, that's actually a great way to learn and get comfortable with any CMS (not just Drupal).
