Installation of the sample content is simple, but must be run as the root user from a bash prompt on the Avalon system. The process for this depends on which kind of installation you have.
su rootto become the root user. This will require the root password you provided the first time the system was booted.
vagrant sshto log in as the vagrant user, then type
sudo -ito become the root user.
If running a manual installation, a hard link needs to be created so that the sample content rpm can find avalon in the '/var/www/avalon/current' directory.
ln -s /var/www/avalon/ /var/www/avalon/current
Once you have a root prompt, run rpm with the correct rails environment (RAILS_ENV) for your setup.
RAILS_ENV="production" rpm -i http://www.avalonmediasystem.org/downloads/avalon-sample-content.noarch.rpm
Note: for R3, substitute this URL instead: http://www.avalonmediasystem.org/downloads/avalon-sample-content-3.0-1.noarch.rpm
If the install fails and you need to rerun the installation, add the --force flag to the rpm command.
Once the sample content has been loaded, you should be able to discover, view, and play it back. Open a web browser, connect to your avalon instance, and select Sample Collection from the Collection facet on the left side of the page.
