 <\/p>\n

The demo aims at running rails application behind Nginx using Passenger. Nginx is a high performance webserver. Passenger is a free web server\/application server with support for Rails, Python, Node.js<\/a>. Passenger is highly stable and fast already service over 350,000 websites.<\/p>\n

1. Installing the deployment tools<\/h2>\n

Installing Development tools:-<\/p>\n

[js]yum install "Development Tools" -y[\/js]<\/p>\n

Installing EPEL repository for installing Nginx:-<\/p>\n

[js]
\n# Enable EPEL Repository
\nsudo su -c ‘rpm -Uvh http:\/\/dl.fedoraproject.org\/pub\/epel\/6\/x86_64\/epel-release-6-8.noarch.rpm’<\/p>\n

# Update everything, once more.
\nyum -y update
\n[\/js]<\/p>\n

 <\/p>\n

2. Setting up Ruby and Rails<\/h2>\n

RVM is a perfect tool for installing and managing Ruby\/Rails.<\/p>\n

[js]curl -L get.rvm.io | bash -s stable
\nsource \/etc\/profile.d\/rvm.sh[\/js]<\/p>\n

After the RVM installed, Install Ruby using RVM:-<\/p>\n

[js]rvm install 2.1.0[\/js]<\/p>\n

Nodejs is also required as rails requires a javascript interpreter.<\/p>\n

[js] yum install nodejs npm –enablerepo=epel
\ngem install bundler rails[\/js]<\/p>\n

 <\/p>\n

3. Installing Server applications<\/h2>\n

3.1 Installing Passenger<\/h3>\n

We will be using gem to install passenger instead of the yum repository for the latest gem installation.<\/p>\n

[js]gem install passenger[\/js]<\/p>\n

Run the command passenger<\/code> to verify the passenger installation:-<\/p>\n

[js]Phusion Passenger Standalone, the easiest way to run web apps.<\/p>\n

Available commands:<\/p>\n

passenger start Start Phusion Passenger Standalone.
\n passenger stop Stop a Phusion Passenger instance.
\n passenger status Show the status of a running Phusion Passenger instance.<\/p>\n

Run ‘passenger <COMMAND> –help’ for more information about each command.
\n[\/js]<\/p>\n

3.2 Setting up Nginx<\/h3>\n

Nginx must be compiled with Passenger for compatibility. This method is more preferred in comparision of installation from default repository. Installation can be done via Passenger application itself.<\/p>\n

Compiling and installing Nginx with Passenger compatibility:-<\/p>\n

[js]passenger-install-nginx-module[\/js]<\/p>\n

Confirm the choice of language (in our case Ruby). Usually it detects and selects the languages already installed on the server.<\/p>\n

[js]
\nUse <space> to select.
\nIf the menu doesn’t display correctly, ensure that your terminal supports UTF-8.<\/p>\n

\u2023 \u2b22 Ruby
\n \u2b22 Python
\n \u2b22 Node.js
\n \u2b21 Meteor
\n[\/js]<\/p>\n

In next step, select 1st option i.e.<\/p>\n

“Yes download and install Nginx for me
\nPress enter to continue.”<\/h4>\n

 <\/p>\n

4. Creating a sample Rails app\/upload the source code<\/h2>\n

Perform the below steps to create a sample application:-<\/p>\n

[js]
\n# Create a sample Rails app
\ncd \/usr\/local\/src
\nmkdir app
\ncd app
\nrails new testapp
\n\t#This will create the basic directory and file structure for rails app
\n\t# app –> application
\n\t# bin –> any binaries\/executables
\n\t# config –> config dir
\n\t# config.ru
\n\t# db –> DB (SQLLite)
\n\t# Gemfile
\n\t# Gemfile.lock
\n\t# lib –> library dir
\n\t# log –> logs
\n\t# public
\n\t# Rakefile
\n\t# README.rdoc
\n\t# test
\n\t# tmp
\n\t# vendor<\/p>\n

cd testapp<\/p>\n

#create controllers and pages to be used as home page in our app
\nrails generate controller pages
\n[\/js]<\/p>\n

Edit the file app\/controllers\/pages_controller.rb<\/code> and add the following lines to create the home action<\/p>\n

[js]class PagesController < ApplicationController
\ndef home
\n @response= "Hello World!"
\nend
\nend [\/js]<\/p>\n

Create the home route in file config\/routes.rb<\/code><\/p>\n

[js] root to: ‘pages#home'[\/js]<\/p>\n

Edit the file app\/views\/pages\/home.html.erb <\/code><\/p>\n

[js]<%= @response %> [\/js]<\/p>\n

In the above app we have created a variable response<\/code> in pages_controller.rb<\/code> which has the value \"Hello World!<\/code>. This variable is used to display the Hello World<\/code> from the file app\/views\/pages\/home.html.erb <\/code><\/p>\n

Execute the following command to set the RAILS_ENV<\/code>.<\/p>\n

[js]RAILS_ENV=development<\/p>\n

[\/js]<\/p>\n

Test your app :<\/p>\n

[js]cd \/usr\/local\/src\/app\/testapp
\n rails s
\n #visit the url http:\/\/yourip:3000
\n[\/js]<\/p>\n

 <\/p>\n

5. Configuring Nginx<\/h2>\n

Edit \/opt\/nginx\/conf\/nginx.conf and add the following directive after the passenger_root <\/code> and passenger_ruby<\/code> directives inside http {.....}<\/code>:-<\/p>\n

[js]passenger_app_env development;[\/js]<\/p>\n

Further delete\/comment the below section in server {....}<\/code><\/p>\n

[js]# location \/ {
\n# root html;
\n# index index.html index.htm;
\n# }
\n[\/js]<\/p>\n

and add the below lines:-<\/p>\n

[js]root \/usr\/local\/src\/app\/testapp\/public;
\npassenger_enabled on;
\n[\/js]<\/p>\n

Start the Nginx server:-<\/p>\n

[js] \/opt\/nginx\/sbin\/nginx [\/js]<\/p>\n

 <\/p>\n

Now, visit the ip of you server http:\/\/yourserverip<\/code>. The Rails default welcome page should be up now. Hope this blog was useful in setting up Rails with Nginx.<\/p>\n","protected":false},"excerpt":{"rendered":"
