Phusion Passenger (informally also known as mod_rails and mod_rack) is a free module for the Apache HTTP Server and nginx for deployment of Ruby applications, including those built using the Ruby on Rails framework. It is available as a Gem package and is supported on Unix-like operating systems.
In order to run the ruby applications only we can use the Phusion Passenger Standalone.
Phusion Passenger Standalone is a web server that allows one to run Ruby web applications. Here are some of the highlights:
Unlike Phusion Passenger for Apache and Phusion Passenger for Nginx, Phusion Passenger Standalone does not require an external web server, it is its own and therefore extremely easy to get started.
It is powered by an Nginx core. This allows it to serve static files at blazing speeds, makes it secure enough to be directly attached to port 80, and allows it to handle slow clients. You don’t need to have Nginx already installed.
Automatically spawns and shuts down application processes. One Phusion Passenger Standalone instance can therefore handle multiple simultaneous connections and handles resource management for you. Crashing application processes are automatically restarted.
Can listen on a Unix socket, for use in reverse proxy setups.
Now in order to install the Phusion Passenger Standalone in the server please run the below comamnd
# gem install passenger
Now in order to start the application run the below command.
Go to your application’s root directory, and run: ( The directory in which applications uploaded ).
# passenger start
First time it will install the Nginx in the server from their repositories.

This will start Phusion Passenger on port 3000. If you want to run it on a different port, use the -p option
# sudo passenger start -p 80
From the above document root you can see the default document root is “ /root/public/ “
