Do you want to make sure that your files remain secure on the server? With the Encryption Application enabled, all files stored on the ownCloud server are encrypted to your password.

To run ownCloud, your webserver must have the following installed: php5 (>= 5.3), php5-json php-xml php-mbstring php5-zip php5-gdAnd as optional dependencies: php5-sqlite (>= 3), curl, libcurl3, libcurl3-dev, php5-curl, php-pdo

  • apt-get install apache2 php5 php5-json php-xml php-mbstring php5-zip php5-gd
  • apt-get install php5-sqlite curl libcurl3 libcurl3-dev php5-curl php-pdo

You don’t need any WebDAV support of your webserver (i.e. apache’s mod_webdav) to access your ownCloud data via WebDAV, ownCloud has a WebDAV server built in.

  1. Download the server file.
  2. Extract ownCloud and copy to your webserver
    • tar -xjf path/to/downloaded/owncloud-x.x.x.tar.bz2cp -r owncloud /path/to/your/webserver
  3. Set the directory permissions: The owner of your webserver must own the apps/, data/ and config/ directories in your ownCloud install. You can do this by running the following command for the apps, data and config directories:
    • chown -R www-data:www-data /path/to/your/owncloud/install/data Replace ‘www-data:www-data’ with the user and group of the owner of your webserver. Note that the data/ directory will only be created after setup has run (see below) and is not present by default in the tarballs.
  4. Enable .htaccess and mod_rewrite if running apache
    If you are running the apache webserver, it is recommended that you enable .htaccess files as ownCloud uses them to enhance security and allows you to use webfinger. To enable .htaccess files you need to ensure that ‘AllowOverride’ is set to ‘All’ in the ‘Directory /var/www/’ section of your virtual host file. This is usually in /etc/apache2/sites-enabled/000-default. You should also run ‘a2enmod rewrite’ and ‘a2enmod headers’. Then restart apache: service apache2 restart (for Ubuntu systems).In order for the maximum upload size to be configurable, the .htaccess file in the owncloud folder needs to be made writable by the server.
  5. Follow the install wizard
    Open your web browser and navigate to your ownCloud instance. If you are installing ownCloud on the same machine as you will access the install wizard from, the url will be:https://localhost/ (or https://localhost/owncloudFor basic installs we recommend SQLite as it is easy to setup (ownCloud will do it for you). For larger installs you should use MySQL or PostgreSQL. Click on the Advanced options to show the configuration options. You may enter admin credentials and let ownCloud create its own database user, or enter a preconfigured user. If you are not using apache as the webserver, please set the data directory to a location outside of the document root. See the advanced install settings.
  6. Finished
    Login and start using ownCloud! For more details on configuring your ownCloud, please visit the Support Centre. If you plan on using the Webfinger app and your ownCloud installation is not in the webroot then you’ll have to manually link /var/www/.well-known to /path/to/your/owncloud/.well-known.
