In order to install Refinery CMS, the first thing you need to do is get RVM and Ruby installed:

\curl -L https://get.rvm.io | bash -s stable
source /etc/profile.d/rvm.sh
rvm install ruby

Now we need to install MySql and imagemagick:

sudo apt-get install mysql-client mysql-server libmysqlclient-dev imagemagick

Now install Rails and the refinerycms gem:

gem install refinerycms

Then, create a new Rails (note that refinerycms does not yet work with Rails 4) project using the refinerycms template:

mkdir /var/rails
cd /var/rails
rails _3.2.19_ new my_app -m http://refinerycms.com/t/2.1.0

Finally, create a Refinery application with:

refinerycms my_app

We can start it with:

cd my_app
rails serve

It should now be visible at http://your.ip.address:3000/refinery
