Rails In deployment

Web And App Server

Web Server is designed to serve HTTP Content.App Server can also serve HTTP Content but is not limited to just HTTP. Web Server is mostly designed to serve static content Most of the application servers have Web Server - Application level services such as Connection Pooling, Object Pooling, Transaction Support, Messaging services etc. Most of the production environments have web server acting as reverse proxy to app server.

Phusion Passenger

Fast and robust web server and application server Supports applications written in multiple programming languages Phusion Passenger is a robust module for Apache and Nginx servers

Deploying Rails App with Phusion Passenger and Nginx

    # Download source code
    cd /tmp
    wget http://nginx.org/download/nginx-1.0.15.tar.gz
    tar -xvzf nginx-1.0.15.tar.gz

    # Install  passenger
    gem install passenger 

    #  configure your Nginx to work with Passenger.
    passenger-install-nginx-module

    # nginx config file 
    sudo nano /opt/nginx/conf/nginx.conf

    # simple configuration
    server { 
        listen 80; 
        server_name example.com; 
        passenger_enabled on; 
        root my-rails-app/public;
