Apache2 Configuration

The apache2 configuration allows users on the system to have web-pages served from directories ~user/public_html/. A file ~user/public_html/index.html can be accessed from the outside as http://tiger.itu.dk/~user/index.html.

For more complex web-server configurations, users may run their own Apache2 instance (apache2 -f apache2.conf) and have the main apache server (running on port 80) proxy requests to the specialized Web server using a virtual host configuration:

<VirtualHost *>
   ServerAdmin webmaster@localhost
   ServerName www.smlserver.org
   ServerAlias smlserver.org
   ProxyRequests Off
   <Proxy *>
      Order deny,allow
      Allow from all
   ProxyPass / http://www.smlserver.org:8001/
   ProxyPassReverse / http://www.smlserver.org:8001/

The virtual host configuration above is stored in /etc/apache2/sites-available/smlserverorg and there is a link to the file in /etc/apache2/sites-enabled/.
