I've search online and been reading documentation for Apache, Passenger, Rack, etc, but have yet to find a solution to my problem. I appreciate if you can help...

I have several Rack (ruby)-based apps, located in

/home/web/sites/app1 /home/web/sites/app2 /home/web/sites/app3 

app1 is a Sintra app, app2 is Padrino and app3 is Rails.

I would like to run these apps under different IPs (assuming server IP is 50.60.70.101):

50.60.70.101:4567 -> app1 50.60.70.101:3000 -> app2 50.60.70.101:80 -> app3 

What is the correct way to configure Apache's virtual host file to achieve this?

I have 3 files in /etc/apache2/sites-available/ with this type of configuration (with changed IPs):

<VirtualHost *:4567> RackEnv production DocumentRoot /home/web/sites/app1/public <Directory /home/web/sites/app1/public> Order allow,deny Allow from all Options -MultiViews #AllowOverride All </Directory> </VirtualHost> 

But I cannot access app1 at 50.60.70.101:4567 (app3 does work on port 80, though)
