Overview:

This document describes what we have now, not what we'd like to have. We're working to split all our services (Solr, Fedora, Apache / Drupal, Djatoka, etc.) out onto different virtual machines.

We currently have testing, staging, and production environments. We use Jenkins and a GitHub repository to move versions of the codebase from Testing to Staging and then to Production.

Testing

  • Red Hat Enterprise Linux Server release 6.6 (Santiago)
  • 2 CPU
  • 4 GB RAM

Staging

  • Red Hat Enterprise Linux Server release 6.6 (Santiago)
  • 4 CPU
  • 4 GB RAM

Production

  • Red Hat Enterprise Linux Server release 6.6 (Santiago)
  • 4 CPU
  • 16 GB RAM

Tomcat webapps:

We currently use an external Tomcat on our Testing machine and the one that's internal to Islandora/Fedora on our Staging and Production machines. The list of webapps running are the same across all three environments.

Software versions:

  • Apache/2.2.15
  • Solr 4.2
  • Fedora 3.5
  • GSearch 2.4.1
  • Adore-Djatoka 1.1
  • Islandora 7.x-1.4
  • Wowza Streaming Server 2.2.0.4709
  • OpenJDK 64-Bit Server VM 1.7.0_75
  • MySQL Ver 14.14 Distrib 5.1.73
  • Tomcat 7.0.33

Settings:

  • ffmpeg: --enable-gpl --enable-version3 --enable-nonfree --enable-postproc --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libdc1394 --enable-libfaac --enable-libgsm --enable-libmp3lame --enable-libopenjpeg --enable-libschroedinger --enable-libspeex --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libxvid
  • JAVA_OPTS: "-Xmx8192m -XX:MaxPermSize=256m -Djava.awt.headless=true -Dkakadu.home=/opt/adore-djatoka/bin/Linux-x86-64 -Djava.library.path=/opt/adore-djatoka/lib/Linux-x86-64"
  • PHP memory limit: 512M

Future Plans

We'd like to have a Packer.io build for each of our services (Solr, Fedora, Apache / Drupal, etc.) and a way to orchestrate them so we could move towards the goal of an immutable server. We also plan to use Drush Make instead of our current all-in-one repository.
