One of the great features of Drupal is its ability to run any number of sites from one base installation, a feature generally referred to as multisites . Creating a new site is just a matter of creating a settings.php file and (optionally) a database to go with your new site. That's it. More importantly, there's no need to set up complicated Apache Virtual hosts, which are a wonderful feature of Apache, but can be very tricky and tedious, especially if you're setting up a large number of subsites.
No worries, there is a solution.
