h1. Owncloud cli cheatsheet
h2. 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
h2. 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 /var/www/owncloud/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)
* *occ user:resetpassword [user]* will allow resetting a user password
* *occ user:lastseen [user]* will show when the user last logged in
* *occ user:report* will show a report of how many users are in the system
h2. Command line upgade procedure
* ssh into the server hosting the Owncloud instance
* go to /var/www/owncloud/updater or /var/www/nextcloud/updater
* run this command
<pre> sudo -u www-data php updater.phar </pre>
* wait a little bit! if it happens too fast, it didn't update.
* In the web console, go to Overview > Settings to see if it updated. For example: https://cloud.rainforestfoundation.org/owncloud/index.php/settings/admin/overview
* Refer to "documentation":https://docs.nextcloud.com/server/16/admin_manual/maintenance/update.html#using-the-command-line-based-updater if needed.
h2. Docker upgrade procedure
* using a docker-compose setup
* go to /opt/nextcloud-docker
* @sudo docker-compose pull && sudo docker-compose build@
* if those two things work correctly, run @docker-compose up -d@
* then @sudo docker-compose exec --user www-data app php occ maintenance:mode --off@
h2. Old Upgrade Procedure
* upgrade package via apt-get
* run @sudo -u www-data php /var/www/owncloud/occ upgrade@
** upgrade may take a long time
* after completing run @sudo -u www-data php /var/www/owncloud/occ maintenance:mode --off@
