Owncloud

Our owncloud installation is running on lucius, which is currently running Debian jessie. The owncloud package, however, comes from the ​ownCloud repo (see #11039).

Important details

• As per the Debian packaging, it is run as the www-data user
• Directories:
  • The code is in /var/www/owncloud.
  • The data (files) are in /var/lib/owncloud/data.
  • Our theme is in /var/lib/owncloud/themes (symlinked from /var/www/owncloud/themes)
  • Our configuratio is in /etc/owncloud (symlinked from /var/www/owncloud/config)
• We're using the postgres package not the mysql package. If you want to muck around in the database: su - www-data and then psql owncloud
• We're authenticating using the login-service (web api).
  • User accounts are created on the fly.
  • This code is in the /etc/owncloud/config.php file (and must be re-copied when admin config changes are applied).
  • The code has to stay in config.php or it won't work in all cases (I tried to make a third party app with this code - but the third party app is not invoked withn you download the ics version of the calendar).
  • This is a real pain.
• The admin username and password are in keyringer. However, try to avoid logging in as the admin, and if you change any configuration options, /etc/owncloud/config.php may get overwritten (which contains our custom user backend). A copy should be available at /etc/owncloud/config.php.bak
• A 5GB per user quota is set. This is configured by logging in as admin and then clicking to administer users. Quotas can be changed on a per user basis.
• To fix #8125, we've added our own custom theme called "mayfirst", which is in lucius.mayfirst.org:/var/lib/owncloud/themes and it is activated via the theme => "mayfirst" line in lucius.mayfirst.org:/etc/owncloud/config.php. Currently, it only adds a style sheet that simply hides the password change form.
• We have committed to maintaining four extra apps, which are installed in /var/lib/owncloud/apps-local:
  • ​Documents
  • ​Calendar
  • ​Contacts
  • ​Grauphel (see #10305)
  • ​Bookmarks (see #10696)

Upgrading

The current version is from the owncloud Debian repositories (see /etc/apt/sources.list.d/owncloud.list, which points to ​http://download.owncloud.org/download/repositories/stable/Debian_8.0/). The server is pined to ownCloud 8 to prevent an upgrade to 9 (see /etc/apt/preferences.d/owncloud.pref).

However, version 8, while still supported by ownCloud, is no longer in the Debian repository. So, to do a minor upgrade, we will have to switch from the debian ownCloud package to ownCloud source package.

Steps to upgrade from source:

• Visit ​https://owncloud.org/changelog/ and download the appropriate version to /root using wget and unpack
• Create symlinks that mirror the symlinks in /var/www/owncloud
• If upgrading a major version, backup /var/lib/owncloud/apps-local and download new versions of all apps in /var/lib/owncloud/apps-local, replacing the existing apps with the new ones.
• Copy /etc/owncloud/config.php to /etc/owncloud/config.php.bak
• Enter maintenance mode (edit to /etc/owncloud/config.php)
• Backup the database with:

  su -c "pg_dump owncloud" www-data | gzip - > owncloud.pre.$(date +%Y.%m.%d).backup.sql.gz
  

• Ensure the dump completed successfully:

  tail owncloud.sql
  

• Make a backup of the current owncloud installation:

  mv /var/www/owncloud /var/www/owncloud.version.n.n.n
  

• Move the new copy in:

  mv /root/owncloud /var/www/
  

• Ensure all database udpates have been run, su to the www-data user and then:

  su - www-data
  cd /var/www/owncloud
  php occ upgrade
  

• Fix /etc/owncloud/config.php to include our custom class (reference /etc/owncloud/config.php.bak).
• Login as mfpl-admin (password in key ringer) and ensure all the experimental apps are enabled.
