I recently decided to try out Rails. When working with PHP, I simply had all of my PHP projects in the same directory. For example, I may have http://ubuntu/app1, http://ubuntu/app2, etc.

I created a subdomain for Rails (http://ruby.ubuntu), installed Rails and Passenger and everything is working. However, I may be wrong, but it looks like I can only have one Rails app per subdomain?

My VirtualHost is as follows:

<VirtualHost *:80>
    ServerName ruby.ubuntu
    ServerAdmin webmaster@localhost

    DocumentRoot /var/www/ruby/blog/public

    <Directory /var/www/ruby/blog/public>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Order allow,deny
        allow from all
        RailsEnv development
    </Directory>

    ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
    <Directory "/usr/lib/cgi-bin">
        AllowOverride None
        Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
        Order allow,deny
        Allow from all
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/error.log

    # Possible values include: debug, info, notice, warn, error, crit,
    # alert, emerg.
    LogLevel warn

    CustomLog ${APACHE_LOG_DIR}/access.log combined

</VirtualHost>

All of my PHP and misc. files are stored in /var/www/main. I want to be able to store all of my Rails apps in /var/www/ruby. I tried changing DocumentRoot to /var/www/ruby, but I don't think it's as simple as that. When I browse to a Rails app's Welcome Aboard page and click on "About my application's environment," I get a 404 page, but when the DocumentRoot is set to the public directory, I get the expected result.

I don't want to have to create a new subdomain every time I create a new project. Is there any way I can make it so I can store all of my apps in /var/www/ruby, and browsing to http://ruby.ubuntu will let me access all of my Rails apps there? That way if I want to create a new app, all I have to do is rails new app, no Apache .htaccess or VirtualHost configuration required.
