Installing Apache 2 in Ubuntu Feisty

Before installing, please ensure that apache is not installed, else uninstall it.
*Apache modules are reported not to work with Apache2 modules.
1) To uninstall Apache
sudo apt-get remove apache
*alternatively, this can be done through sypnatic package module
2) Update apt-get's package list
sudo apt-get update (to subscribe to updated packages)
3) Install Apache2
sudo apt-get install apache2
4) The system should print out a message saying that apache2 is running. To test,
type http://localhost/ in a browser. You should be able to see the apache-default folder.
5) If step 4 fails, check /etc/default/apache2
ensure that NO_START = 0 to enable apache2 to start at port 80.
It could be that NO_START = 1 if apache was installed in your system and prevented Apache2 from starting at port 80.
6) Restart apache2
sudo /etc/init.d/apache2 restart

* commands to clean up source codes / downloaded files which are no longer in used
sudo dpkg --purge apache apache2
