How do I serve multiple Passenger apps from a single nginx instance?

Question

In order to keep my memory footprint to a minimum, I would like to know if it's possible to serve more than one application on WebFaction from a single Passenger instance. I just need to create an additional server entry, but I can't find a way to manually proxy it. It seems like it'd be a waste if I created more than one Passenger/Rails "application" if I already have nginx up and running with the first one.

Is this possible?

Using multiple Rails applications suggests "smart-lvl2" spawning method (see this), which takes much more memory than the "conservative" spawning we are using by default. In general, you should just stick with the one-app-per server scheme for Rails applications.

Just found the answer to my own question:

Create a "Custom Application" in the WebFaction control panel which will assign a port number. Then, modify nginx.conf to add an additional server directive like so:

server {
    listen             00000; # Replace with the "Custom Application" port number
    passenger_enabled  on;
    root               /home/username/webapps/passenger_app_name/new_app/public;
    server_name        localhost;
}

You don't need to use multiple ports - you should be able to just use the domain name for the second site in the server_name directive, eg:

server {
    passenger_enabled  on;
    root               /home/username/webapps/passenger_app_name/app1/public;
    server_name        domain1.com www.domain1.com;
}
server {
    passenger_enabled  on;
    root               /home/username/webapps/passenger_app_name/app2/public;
    server_name        domain2.com www.domain2.com;
}

Then just assign your passenger app to whatever site in the control panel.
