Ruby on Rails Installation Process

We are using a Ubuntu machine for this installation and practice.

Install Ruby on Rails using "rbenv" on Ubtuntu:

• Install the required packages and pre-requisites:

    sudo apt-get update -y
    sudo apt-get install -y git gitk
    sudo apt-get install -y gcc build-essential libpq-dev libssl-dev libreadline-dev libsqlite3-dev zliblg-dev

• Clone the rbenv repository:

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

• Export the RECIPE PUPPY site with port to bashrc:

    echo 'export RECIPEPUPPY_HOSTPORT=www.recipepuppy.com:80' >> ~/.bashrc

• Export rbenv/bin:

    echo 'export PATH="$PATH:/GitHub/ruby/.rbenv/bin"' >> ~/.bashrc
    echo 'eval "$(rbenv init .)"' >> ~/.bashrc

• Now clone the ruby-build repository:

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

• Set path for this plugins directory:

    echo 'export PATH="$PATH:/GitHub/ruby/.rbenv/plugins/ruby-build/bin"' >> ~/.bashrc

• Now we need to source the bashrc as we have some entries into it.:

    source ~/.bashrc

• Lets begin the installation now:

    rbenv install -v 2.2.2

• Lets set the default version of Ruby:

    rbenv global 2.2.2
    ruby -v

• We need to stop the gems to generate local documentation:

    echo "gem: --no-document" > ~/.gemrc

• Install the Ruby gem manager:

    gem install bundler

• Install Rails:

    gem install rails -v 4.2.3

• Now we need to rehash as it will let us to get command completion which relates to rails.

    rbenv rehash

• Let us install some other packages which are needed in our practice

    sudo apt-get install -y software-properties-common python-software-properties

• Now let us install some javascripts through a custom location

    sudo add-apt-repository ppa:chris-lea/node.js
    sudo apt-get install -y node.js
    sudo apt-get install -y bzip2

• Let us setup path for some ENV

    echo 'export PHANTOM_JS="phantomjs-1.9.8-linux-x86-64"' >> ~/.bashrc

• Let us download and install the PhantomJS package:

    cd /tmp
    curl -L https://bitbucket.org/ariya/phantomjs/downloads/$PHANTOM_JS.tar.bz2 | tar -xjvf
    sudo mv $PHANTOM_JS /usr/local/share
    sudo ln -s /usr/local/share/$PHANTOM_JS/bin/phantomjs /usr/local/bin
    phantomjs -v

• Install text editor:

    curl http://c758482.r82.cf2.rackcdn.com/Sublime%20Text%202.0.2%20x64.tar.bz2 | tar -xjf
    sudo mv 'Sublime Text 2' /opt/SublimeText2
    echo 'export PATH=$PATH:/opt/SublimeText2' >> ~/.bashrc
    source ~/.bashrc

• Let us check all the versions now

    git --version
    phantomjs -v
    ruby -v
    rails -v

• Now let us create a rails application
  Create a project directory and then create a application

    mkdir /u01/ruby/projects &&cd /u01/ruby/projects

    rails new test-install -q

NOTE: Here we are using -r to run this command in quite mode as it will produce lot of output.

• Now cd into the new rails application we have created and run the server

    cd test-install ; rails server

• Let us check the application in the browser

    http://localhost:3000

• Now we have completed configuring ruby on rails.
