Deploying multiple Rails apps to same domain using sub URI's, nginx and passenger.

I recently had a requirement where I had to run two different Rails app's on the same domain with different sub URI's. The following was what I wanted to achieve: - Load Rails App1 - Load Rails App2
This is very easy to achieve provided you are using Passenger Phusion + nginx. I made the following changes to the server block in nginx.conf
server {
  listen 80; 
  root /var/www/app1/public;
  passenger_enabled on;
  passenger_base_uri /app2;
Look at how the
is pointing to app1's public folder. And look at the new addition
directive. Now, we need to carry out the final step - symlink app2's public folder to /var/www/app1/public/app2.
ln -s /var/www/app2/public /var/www/app1/public/app2 
Once the symlink is created, restart nginx and you are ready to serve different Rails apps on the same domain.
