puppet-dspace-demo

This repo includes the server initialization files for the 'https://demo6.dspace.org' server.

This includes the following:

• cloud-init.yaml : a cloud-init Config data file (to be passed via userdata) to initialize server in EC2
• Puppetfile : a librarian-puppet config file used to install all necessary Puppet modules
• manifests/site.pp : the actual Puppet script to run via 'puppet apply'
• Basic configs required for Puppet

How to use it

1. Spin up a new Ubuntu 16.04 LTS (64-bit, HVM Virtualization, EBS-SSD boot), e.g. ami-e3c3b8f4 from Ubuntu's Amazon EC2 AMI Locator
   • Select instance size (currently using 'm3.medium' for demo.dspace.org)
   • Upload the included 'cloud-init.yaml' as "User Data"
   • Storage: Update to at least 75GB storage for ROOT
   • Launch the instance
2. Sit back and wait while 'cloud-init' & Puppet does all the hard work for you.
   • The entire process may take ~15 mins
3. If you want to check on the status:
   • SSH to the server
   • tail -f /var/log/cloud-init-output.log
   • Once it reports System boot (via cloud-init) is COMPLETE, then the server is done setting itself up.

How it works

All of the hard work is taken care of by cloud-init (and Puppet). Here's what the cloud-init.yaml does for you:

1. Sets the server hostname & FQDN
2. Adds all necessary Apt repositories
3. Runs 'apt-get update' and 'apt-get upgrade' to ensure all is up-to-date (reboots if needed)
4. Installs all necessary software on server (e.g. Puppet, librarian-puppet, Git)
5. Clones this 'puppet-dspace-demo' GitHub repo to server (at /etc/puppet/)
6. Runs 'librarian-puppet' to install any Puppet module dependencies (specified in Puppetfile)
7. Runs puppet apply /etc/puppet/manifests/site.pp to actually install Postgres, Tomcat, Apache and DSpace (using the Puppet modules for each)

Note: all actions taken by 'cloud-init' are logged to /var/log/cloud-init.log. The output/results are logged to /var/log/cloud-init-output.log.

What it sets up

The Puppet script that does all the setup is manifests/site.pp.

Here's what it currently does:

1. Setup Ubuntu unattended_upgrades (via puppet-unattended_upgrades module)
2. Setup DSpace, including all prerequisites (via our separate puppet-dspace module). This includes setting up all of the following:
   • PostgreSQL database (via puppetlabs-postgresql module)
   • Tomcat (via puppetlabs-tomcat module)
   • Apache web server (via puppetlabs-apache module), communicates with Tomcat via AJP
   • 'dspace' OS user account (which is the owner of DSpace installation)
3. Setup splash page (homepage of http://demo.dspace.org), by checking out/installing the https://github.com/DSpace/demo.dspace.org project
   • Also includes the useful scripts / cron jobs from that project
4. 'kompewter' IRC bot (from https://github.com/DSpace-Labs/kompewter)
5. Setup custom Message of the Day for server and other basic files

NOTE: Currently this script downloads AIPs from a private S3 location to the ~dspace/AIP-restore folder. If you wish to copy/clone this script for your own purposes, you can skip this step, or create your own content that looks something like this:

• ~dspace/AIP-restore/
  • SITE@10673-0.zip (Site AIP corresponding to 10673/0 handle)
  • COMMUNITY@[handle].zip (one or more Community AIPs using 10673 handle prefix)
  • COLLECTION@[handle].zip (one or more Collection AIPs using 10673 handle prefix)
  • ITEM@[handle].zip (one or more ITEM AIPs using 10673 handle prefix)
• A restore script is installed to ~/bin/reset-dspace-content (under the 'dspace' OS user account). At this time, it must be manually run after DSpace is installed (it is not automated).
