Now that KAMP has successfully been set up on a Kubuntu box, setting up multiple sites on one server is the next logical step. This allows you to do Drupal testing in multiple versions/setups at the same time on one localhost server. To begin, open up Konsole (command line utility) and change to the Apache2 sites-available directory (this is where Apache stores the setup files for each Virtual Host):
cd /etc/apache2/sites-available/
Next, login as root and copy the existing default setup file and name it to the "server" you want to use:
sudo -s (prompts you for your password)
cp default exampleSite
Using your favorite text editor, modify the newly copied file so that it points to the correct files (using VI in this example):
vi exampleSite
Modify/Add the following lines:
NameVirtualHost * to NameVirtualHost exampleSite:80
<VirtualHost *> to <VirtualHost exampleSite:80>
Add ServerName exampleSite
DocumentRoot /var/www/ to DocumentRoot /var/www/exampleSite/
