Preparing for the Upgrade

Before doing anything to prepare for the upgrade, backup your Avalon 3.1 installation.

See What's New in Avalon 3.2 for more details.


The following instructions will work for any Avalon 3.1 installation that used Puppet as its source. This includes the portable VM Image Installation, the Vagrant Virtual Machine Installation, and the Manual Installation of Avalon Using Puppet.

Upgrading is fairly simple, and 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.

Once you have a root prompt, proceed with the upgrade as follows:

# 1. if starting from Portable VM image, download the installer package, unpack, and link it
$ wget -O flat.tar.gz 
$ tar xzf flat.tar.gz
$ export INSTALL_DIR=`pwd`
$ ln -s $INSTALL_DIR/avalon-installer-flat/files /etc/puppet/avalon_files

# 2. navigate to the installer
$ cd avalon-installer-flat

# 3. remove the Avalon deploy tag
$ rm -f /var/www/avalon/bare-deploy
$ rm -rf /opt/staging/avalon/avalon-bare-deploy.tar.gz /opt/staging/avalon/avalon-bare-deploy
# 4. apply the puppet manifest
$ puppet apply --fileserverconfig=fileserver.conf --modulepath=modules \
	--hiera_config=hiera/hiera.yaml --templatedir=templates manifests/init.pp

# 5. add configuration for new controlled vocabulary 
# (Merge new identifier type definitions from config/controlled_vocabulary.yml.example into config/controlled_vocabulary.yml and edit as necessary.)

# 6. reindex
$ su - avalon -c "cd /var/www/avalon/current; RAILS_ENV='production' bundle exec rake avalon:reindex"
# 1. Switch to matterhorn user
$ su - matterhorn
$ cd /usr/local/matterhorn
# 2. Install updated modules
$ cd lib/matterhorn
$ wget --no-check-certificate -O matterhorn-distribution-service-hls-1.4-SNAPSHOT.jar
# 3. Install updated encoding profiles
$ cd ../../etc/encoding
$ wget --no-check-certificate -O

# 4. Restart Matterhorn
$ exit
$ service matterhorn stop
$ service matterhorn start
