You have to point the DocumentRoot to the public folder of your Rails app. In your case that would be /var/www/demo/public. See the documentation for more information.

If this is going to be a production server, please seek help from a professional. Else you might leave your application (and your users' data) vulnerable.

In addition to @Wukerplank...

From what you posted, it doesn't seem like you've configured Phusion Passenger (a.k.a. mod_rails)

Here is a link to documentation for Passenger configuration.
