C:\> rails -v

And if the output is something like Rails 4.2.4, you are success!

 

Install Ruby on Rails at Linux

 

In Linux we are can installing Ruby On Rails using rbenv. rbenv can provides an easy installation procedure to manage varous version of Ruby.

 

1. Install Prerequites Dependecies


You must install git-core to install Ruby On Rails. Use the following command for installing Rails using yum.


sudo yum install -y git-core zlib zlib-devel gcc-c++ patch readline readline-devel libyaml-devel libffi-devel openssl-devel make bzip2 autoconf automake libtool bison curl sqlite-devel

 

2. Install rbenv

 

Now we will install rbenv and set the appropriate environment variables. Use the following set of commands to get rbenv for git repository.


git clone git://github.com/sstephenson/rbenv.git .rbenv

echo 'export PATH = "$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile

echo 'eval "$(rbenv init -)"' >> ~/.bash_profile

exec $SHELL

git clone git://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build

echo 'export PATH = "$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' << ~/.bash_profile

exec $SHELL

 

3. Install Ruby

 

We will install Ruby 2.2.3. Use the following command for installing Ruby.


rbenv install -v 2.2.3

Use the following command for setting up the current Ruby version as default.


rbenv global 2.2.3

Use the following command to verify the Ruby version.


ruby -v

 

Output :

ruby 2.2.3p173 (2015-08-18 revivion 51636) [X86_64-linux]

keyword gem for installing the supported dependencies.

 

4. Install Rails

 

Use the following command for installing Rails version 4.2.4.


install rails -v 4.2.4

Use the following command to make Rails executable available.


rbenv rehash

Use the following command for checking the rails version.


rails -v

 

5. Install JavaScript Runtime

 

We will take Node.js from EPEL yum repository. Use the following command to add the EPEL package to the yum repository.


sudo yum -y install epel-release

Use the following command for installing the Node.js package.


sudo yum install nodejs

 

6. Install Database

 

By default, Rails uses sqlite3, but you may want to install MySQL, PostgreSQL, or other RDBMS. This is optional; if you have the database installed, then you may skip this step and it is not mandatory that you have a database installed to start the rails server. For this tutorial, we are using PostgreSQL database. Therefore use the following commands to install PostgreSQL.


sudo yum install postgresql-server postgresql-contrib

Accept the prompt, by responding with a y. Use the following command to create a PostgreSQl database cluster.


sudo postgresql-setup initdb

Use the following command to start and enable PostgreSQL.


sudo systemctl start postgresql

sudo systemctl enable postgresql

Keeping Rails Up-to-Date


Assuming you have installed Rails using RubyGems, keeping it up-to-date is relatively easy. We can use the same command in both Windows and Linux platform. Use the following command :


gem update rails

 

Output :

The following screenshot shows a Windows command prompt. The Linux terminal also provides the same output.
GEM Update.

This will automatically update your Rails installation. The next time you restart your application, it will pick up this latest version of Rails. While using this command, make sure you are connected to the internet.


Installation Verification


You can verify if everything is set up according to your requirements or not. Use the following command to create a demo project.


rails new demo

 

Rails New Demo


It will generate a demo rail project; we will discuss about it later. Currently we have to check if the environment is set up or not. Next, use the following command to run WEBrick web server on your machine.


cd demo

rails server

It will generate auto-code to start the server Rails Server

Now open your browser and type the following http://localhost:3000
