For this tutorial we will be using Ruby 1.9.3 and Rails 3.2.1
First thing update
$ sudo apt-get update
Next, we are going to install git, RVM which is essential for the build
$sudo apt-get install build-essential git-core curl
RVM stands for Ruby Version Manager that is used for installing and managing multiple versions of Ruby at one point of time.
$ curl -L get.rvm.io | bash -s stable
To load RVM into bash, type in
$ echo ‘[[ -s “$HOME/.rvm/scripts/rvm” ]] && source “$HOME/.rvm/scripts/rvm”‘ >> ~/.bashrc
$ source /etc/profile.d/rvm.sh
Reload bashrc by issuing the command
$ . ~/.bashrc
Check rvm requirements
$ rvm requirements
Load all packages that are necessary to be loaded for Ruby to run
$ sudo apt-get 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 ncurses-dev automake libtool bison \
subversion nodejs
Install RVM
$ rvm install 1.9.3
To use RVM, type
$ rvm use 1.9.3
To know the version of Ruby that is installed type
$ ruby -v
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]
To make the Ruby the default version for the user
$ rvm –default use 1.9.3-p194
Install rails by typing
$ gem install rails -v 3.2.3
$ rails new [project name]
$ rvm use 1.9.3-p194@rails3 –rvmrc
You can install MySQL or SQLLite. In this tutorial we will be installing MySQL
$ sudo apt-get install mysql-server mysql-client
