These are the instructions to get Avalon up and running on a clean RHEL machine. Your mileage may vary for other Linux distributions.

Install Avalon

Install developer tools

Install packages required for dependencies to build properly.

yum install gcc-c++ zlib-devel readline-devel openssl-devel java-1.7.0-openjdk

Install RVM to manage Ruby (

curl -L | bash -s stable --ruby

Reload shell environment using the instructions given in rvm's installation output.

Make sure ruby installed correctly

rvm list

Update rubygem

gem update --system

Install bundler for managing dependencies

gem install bundler

Install & setup Git

Install Git

yum install git

The next step is for committers.

Create an account on github and set up SSH keys. For more help see the detailed instructions

cd ~/.ssh
ssh-keygen -t rsa -C ""

Install Matterhorn dependencies

Install subversion

yum install subversion

Download Matterhorn's dependency installation scripts

svn checkout matterhorn_dependencies
cd matterhorn_dependencies

Read the README.txt file for instructions on how to run the ./menu3p installation script.

This may take a LONG time to run so have something else to keep you busy!

Setup Avalon


The next step may be slightly different depending on your operating system if you are not using RHEL6.  When running bundle install you may need to set: QMAKE=/usr/bin/qmake-qt4

Add the required dependencies so that all gems will install properly.

yum install ruby-devel libxml2-devel libxslt libxslt-devel libcurl-devel sqlite-devel

Go to your workspace. This command will download avalon source from github.  Run bundle install to install all of the necessary dependency gems.

git clone
cd avalon
bundle install --gemfile=Gemfile.first
QMAKE=/usr/bin/qmake-qt4 bundle install

Prepare the databases

rake db:migrate
rake db:test:prepare

Install the hydra-jetty, avalon-felix, and avalon-red5 submodules.  The hydra-jetty submodule contains Fedora and Solr and can be managed via jettywrapper rake tasks.  The avalon-felix submodule is a custom instance of Matterhorn. avalon-red5 is a custom instance of Red5 with Matterhorn integration. These two servers can also be controlled with rake tasks.  After installing them, force them to track the master branch for their respective repositories.

git submodule init
git submodule update
cd jetty/ 
git fetch --tags 
git checkout 4.x 
cd ..  
cd felix/
git fetch --tags
git checkout 1.4.x
cd ..  

Start all services

rake jetty:config
rake avalon:services:start

Test Avalon

From your avalon installation execute

rails server

Navigate to http://localhost:3000
