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 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
