Requirements
Ruby

Of course :-)

We tested it with both Ruby 1.8.7 (2009-06-12 patchlevel 174) and Ruby 1.9.2.p0 which are two of Ruby versions Heroku supports.

Please note that performances are much better with Ruby 1.9.2 and the stability seems okay (no bugs found for now).
Mongodb

Locomotive CMS does not use a classic sql database such as mysql or postgresql but rather a nosql database named mongodb.

Mongodb is available on many OS. Check this link out for more information.

Note: We suggest you to take a version from 1.6.0.
ImageMagick

Uploaded images for asset collections are cropped, for example, and Locomotive uses ImageMagick for this purpose. Again, ImageMagick is available on a large set of OS.
Browsers (back-office)

We haven't had time to test the IE versions. So for now, we ask you to use the Locomotive back-office with the following browsers: Safari, Firefox and Chrome.

From source installation

This way of installing Locomotive is recommended when you want to add new features, correct bugs or see how Locomotive works internally.

Get source code from github.

git clone git://github.com/locomotivecms/engine.git locomotive
cd locomotive

Install gems.

bundle install

Edit the Locomotive settings.

mate config/initializers/locomotive.rb

Note: If you run Locomotive in local and with the multi-sites mode on, do not forget to update your /etc/hosts file accordingly.

By default, Locomotive uses Amazon S3 in production. To change it, modify the carrierwave initialization file.

mate config/initializers/carrierwave.rb

You also may want to change your mongodb connection settings.

mate config/mongoid.yml

Run the application server.

bundle exec unicorn_rails

Open your browser.

open http://localhost:8080/admin

Follow the instructions in the browser to create your first account and site.
(ONLY IN PRODUCTION) Push the assets used by the Locomotive back-office to Amazon S3 for better performances.(Jammit-S3).

export S3_KEY_ID=
export S3_SECRET_KEY=
export S3_BUCKET=

jammit-s3 --force

If you do not want to push the assets in S3 and instead leave them in your application, remove the lines about S3 in the config/assets.yml file and run the following command:

jammit --force

Engine installation

This is probably the cleanest way to build your own comprehensive hosting CMS platform because the Locomotive core cannot be broken and all you need to do is add your own content.

First, create a Rails project.

rails new my_platform -O -T -J
cd my_platform
rm public/index.html

You have to tell your Rails app that you want to include the Locomotive gem available on Gemcutter. Edit your application Gemfile and add these lines if missing.

gem 'rails', '3.0.9'
gem 'locomotive_cms', :git => 'git://github.com/locomotivecms/engine.git', :require => 'locomotive/engine'
gem 'unicorn', :group => 'development'

Install gems
