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:

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.
