#Installing RVM.
--------------------------------
RVM is used for managing GEM sets and ruby versions. There is a lot that you can do with it. For more information visit: [RVM website](https://rvm.io/)
##Installing RVM Prereq:
	echo ######Installing pre pre reqs#########
	    sudo apt-get update
	    sudo apt-get upgrade -y
	    sudo apt-get install build-essential zlib1g-dev libssl-dev libreadline-dev \
	    git-core curl libyaml-dev libcurl4-dev libsqlite3-dev apache2-dev -y
##Installing RVM more prereq
	sudo apt-get --no-install-recommends install bash curl git patch bzip2
	sudo apt-get --no-install-recommends install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev libgdbm-dev ncurses-dev automake libtool bison subversion pkg-config libffi-dev
	sudo apt-get --no-install-recommends install curl g++ openjdk-6-jre-headless
##install RVM
	\curl -#L https://get.rvm.io | bash -s stable --autolibs=3 --ruby
##Add source
	echo "source ~/.rvm/scripts/rvm">> ~/.bash_profile
--------------------------------	
#Install Ruby 1.9.3
	rvm install ruby-1.9.3-p392
##Use as default
	rvm --default use 1.9.3
--------------------------------
#Install Rails
##Dependecies
	sudo apt-get install libqt4-dev libqtwebkit-dev
	sudo apt-get install ruby1.9.1-dev
	sudo apt-get install build-essential libopenssl-ruby1.9.1 libssl-dev zlib1g-dev
##Add RVM rails and profile config
	echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && \
	 . "$HOME/.rvm/scripts/rvm"' >> ~/.bash_profile
##Install it.

	gem install rails

If you get error for i18 do the following:

	rvm use 2.0.0
	gem install i18n
	rvm use 1.9.3
	
###Install mysql rails dependecies
	sudo apt-get install libmysql-ruby libmysqlclient-dev
	gem install mysql 
	gem install mysql2
###Installing Passenger 
	sudo apt-get install apache2-prefork-dev
	sudo apt-get install libcurl4-openssl-dev
####Install LAMP

	echo "######INSTALLING PHP and apache and all the requriemtns########"

####INSTALL PASSENGER
	rvm use 1.9.3
	gem install passenger
	passenger-install-apache2-module
####record informatino given
	   LoadModule passenger_module /home/vagrant/.rvm/gems/ruby-1.9.3-p392/gems/passenger-3.0.19/ext/apache2/mod_passenger.so
	   PassengerRoot /home/vagrant/.rvm/gems/ruby-1.9.3-p392/gems/passenger-3.0.19
	   PassengerRuby /home/vagrant/.rvm/wrappers/ruby-1.9.3-p392/ruby
####Example of vhost file
	<VirtualHost *:80>
	     ServerAdmin [email protected]
	     ServerName flitti.com
	     ServerAlias www.flitti.com
	     DocumentRoot /srv/www/flitti.com/flitti/public
	        RailsEnv production
	        <Directory /srv/www/flitti.com/flitti/public>
	                Allow from all
	                AllowOverride all
	                Options -MultiViews
	        </Directory>
	</VirtualHost>	

or
If you want to use the default configuration:

	<VirtualHost *:80>
	    DocumentRoot /srv/www/flitti.com/flitti/public
	    RailsEnv development
	    <Directory /srv/www/flitti.com/flitti/public>
		    Allow from all
		    AllowOverride all
		    Options -MultiViews
	    </Directory>
    </VirtualHost>
###instlal node 
####install the dependcies

	sudo apt-get install python-software-properties python g++ make
####clone node and install

	mkdir -p ~/local/src
	cd ~/local/src
	git clone git://github.com/joyent/node.git
	cd node
	git checkout v0.11.1-release
	./configure --prefix=~/local
	make
	make install
	echo 'PATH=$PATH:$HOME/local/bin' >> $HOME/.bash_profile
	source ~/.bash_profile

	
##Setting up the rails installation app
	sudo chown -R vagrant /srv/
	mkdir -p /srv/www/flitti.com
	cd /srv/www/flitti.com
	rails new flitti -d mysql
##RAKE DB:
	rake db:create	

##Setting up the apache server for rails
Add the loader to the apache config file:
	
	sudo vi /etc/apache2/apache2.conf
And add the config line that you got from passenger installation:
	
	LoadModule passenger_module /home/vagrant/.rvm/gems/ruby-1.9.3-p392/gems/passenger-3.0.19/ext/apache2/mod_passenger.so
	PassengerRoot /var/lib/gems/1.9.1/gems/passenger-3.0.19
	   PassengerRuby /usr/bin/ruby1.9.1

	
Then we need to change the virtual host file. Here is an example:

		<VirtualHost *:80>
		     ServerAdmin [email protected]
	     ServerName flitti.com
	     ServerAlias www.flitti.com
	     DocumentRoot /srv/www/flitti.com/flitti/public
	        RailsEnv production
	        <Directory /srv/www/flitti.com/flitti/public>
	                Allow from all
	                AllowOverride all
	                Options -MultiViews
	        </Directory>
	</VirtualHost>

If you want get something done quickly if you are using a virtual machine and vagrant and don't want to bother with setting up virtual hosts and just want to use port forwarding, it is not recommended, but you can edit the default virtual host file of apache to point to your current rails app. Here is an example. Do:

	sudo vi /etc/apache2/sites-available/default
	
and then copy paste theis:

	    <VirtualHost *:80>
	    PassengerRoot /home/vagrant/.rvm/gems/ruby-1.9.3-p392/gems/passenger-3.0.19
	    PassengerRuby /home/vagrant/.rvm/wrappers/ruby-1.9.3-p392/ruby
	    DocumentRoot /srv/www/flitti.com/flitti/public
	    RailsEnv development
	    <Directory /srv/www/flitti.com/flitti/public>
		    Allow from all
		    AllowOverride all
		    Options -MultiViews
	    </Directory>
    </VirtualHost>
It is important to load the current passenger fconfiguration. And you got that when you installed passenger.

Finally do:

	sudo /etc/init.d/apache2 reload
	sudo /etc/init.d/apache2 restart
If you did everything right, you won't see apache complain, otherwise, you have to fix things up.

###add Javascript runtime:
Add 'therubyracer' gem to your gem file inside your rails application and run bundle.

	gem 'therubyracer'
	bundle
And now you are good to go !

-------------------------------------------------------
-------------------------------------------------------
###MORE Additional stuff that happened during the installation.
###install ref gem
	gem install ref
###Install the therubyracer gme
	gem install therubyracer --version "~> 0.10.2"
	cd /srv/www/flitti.com/flitti

And then do:

	bundle install
Then you need to go to the site and open it in the browser and see what kind of error you get from passenger. then instlal the gem that is missing. In my case:

	gem install coffee-script-source
	touch tmp/restart.txt 
also add the gem in your gem file of rails:
	
	gem 'coffee-script-source'
Then refresh. Then it might not still fix the problem.
But the issue might be that the gems are installed for 2.0.0 version of ruby and not for 1.9.3. If that is the case do:

	rvm use 1.9.3
	bundle install

The other reason might be that passenger needs configuration to work with ruby 2.0.0 gem sets and only works now with 1.9.3. Last step do:

	touch tmp/restart.txt

then add therubyracer gem to your gem file and run bundle:
	
	gem 'therubyracer'
	bundle

Last step is to restart the server:
	
	touch tmp/restart.txt
