This part I will lead you through the process of setting up RVM, GIT, MYSQL, VIM

Above all, lett's install some useful download tools:

aptitude : a better independence management tool than apt-get

axel  : a fast multiply-lina downloader

apt-fast : use aptitude and axel to install sofware, it is awesome!

Then set up apt-fast follow the guaid 
          

(1)  Install the dependences

(2)  Install the latest version of  RVM , Ruby 

(3)   Add rvm function to bash

(4)Install ruby and generate ri-file for the newly installed ruby (so you can use "ri xx" to reffer to the ruby api)

(5) Configure gem not to generate ri and rdoc files, add the following line to ~/.gemrc

(6) Create gemset

Flash the github page, you will see your codes already uploaded

(12)Publish on heruku

As with GitHub, when using Heroku you will need to
create SSH keys if you haven’t already, and then tell Heroku your public key so that you can use Git to push the sample application repository up to their servers: ( ref => http://ruby.railstutorial.org/chapters/beginning?version=3.2#sec:1.4.1 )

Add to Gemfile:

group :prodcution do
  gem 'activerecord-postgresql-adapter'
end

Then

bundle install

gem install heroku
heroku keys:add
heroku create --stack cedar
git push heroku master
heroku rake db:migrate
 heroku open
