Installing Ruby on Rails DA CentOS is not quite a complicated operation.
I never mail this experience and I think, however, that even a layman can handle installation.
Follow these steps:

update the system and install git:

sudo yum update
sudo yum install git

We install the necessary components:

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

We collect and compile components

cd ~
git clone git://github.com/sstephenson/rbenv.git .rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile
echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
git clone git://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bash_profile
source ~/.bash_profile

command

rbenv install -l

Searches us all versions

installation version 2.23 from series 3 I did not want to go

rbenv install -v 2.2.3
rbenv rehash

set as the default installed version:

rbenv global 2.2.3

Checking version:

ruby -v

Installation GEM

gem install bundler

Installing the rails

gem install rails
rbenv rehash

check which version of rails

rails -v

Installation nodejs

sudo yum install nodejs

Create the sample application:

cd ~
rails new pilotapp
cd pilotapp
rake db:create

and its launch:

rails server --binding=ADRESIPSERWERA
