Removing apache2 from ubuntu

Follow these steps to remove the apache2 service using Terminal (we were successfully able to uninstall Apache2 from Ubuntu 12.0.4 LTS):

  1. First stop the apache2 service if it is running with: sudo service apache2 stop
  2. Now remove and cleanup all the apache2 packages with:
    sudo apt-get purge apache2 apache2-utils apache2.2-bin apache2-common
    
  3. Finally, run sudo apt-get autoremove just in case any other cleanup in needed

You can do the following two tests to confirm apache has been removed:

  1. which apache2 – should return a blank line
  2. sudo service apache2 start – should return apache2: unrecognized service

Have a great day!
