Owncloud cli cheatsheet¶

Architecture¶

• Owncloud by default is installed to /var/www/owncloud
• The apache conf file is in /etc/apache2/conf-available/owncloud.conf
  • by default this redirects any http[s[://[url]/owncloud to the owncloud directory
  • I often change this to redirect / to owncloud if on subdomain or office fileserver
• owncloud config file is in /var/www/owncloud/config/config.php
  • note: if setting changes in the config file do not take, check the permissions for this file
• the owncloud directory also has a detailed .htaccess file that is vital to the security of owncloud
• The data directory can be found in the config file and is also the location of the owncloud.log file
  • the data directory can and at office servers is often supplemented or replaced by local storage or SMB
• the backend database is mysql which is used by default for everything.
  • some larger installs (ex. NDWA) use redis instead of mysql for file locking.
• caching is performed by memcached or redis

OCC¶

Occ is the cli command tool for owncloud. Through this tool most user/file/maintenance operations can be performed.
detailed instructions can be found here https://doc.owncloud.org/server/9.0/admin_manual/configuration_server/occ_command.html

key notes/favorite commands:

• Occ must be run as the www-data user!
  • 8.0+ should no longer even allow running as root but if that happens there might be a permission mess to deal with!
  • always use sudo -u www-data php occ (I have aliased this to occ)
• occ upgrade is needed for any major or minor release of owncloud!
  • this will do a database upgrade test and then perform the upgrade
  • for larger installs, this could take some time so only perform this during off hours.
• occ maintenance:mode --off/--on this will gracefully close connections and turn on maintenance mode (or off)
• occ file:scan [user] this will rescan the file cache for [user] or --all for all
  • this doesn't work for samba shares with OC login credentials as OC has no easy capacity for caching credentials for this purpose. (currently being worked on)
