# ownCloud 9.0 Server Administration Manual

# Installing ownCloud From the Command Line

It is now possible to install ownCloud entirely from the command line. This is convenient for scripted operations, headless servers, and sysadmins who prefer the command line. There are three stages to installing ownCloud via the command line:

1. Download and install the ownCloud code via your package manager, or download and unpack the tarball in the appropriate directories. (See Preferred Linux Installation Method and Manual Installation on Linux.)

2. Change the ownership of your `owncloud` directory to your HTTP user, like this example for Debian/Ubuntu. You must run `occ` as your HTTP user; see Run occ As Your HTTP User:

    $ sudo chown -R www-data:www-data /var/www/owncloud/

3. Use the `occ` command to complete your installation. This takes the place of running the graphical Installation Wizard:

    $ cd /var/www/owncloud/
    $ sudo -u www-data php occ  maintenance:install --database
    "mysql" --database-name "owncloud"  --database-user "root" --database-pass
    "password" --admin-user "admin" --admin-pass "password"
    ownCloud is not installed - only a limited number of commands are available
    ownCloud was successfully installed

Note that you must change to the root ownCloud directory, as in the example above, to run `occ maintenance:install`, or the installation will fail with a PHP fatal error message.

Supported databases are:

    - sqlite (SQLite3 - Server Edition Only)
    - mysql (MySQL/MariaDB)
    - pgsql (PostgreSQL)
    - oci (Oracle)

See Command Line Installation for more information.

Finally, apply the correct strong permissions to your ownCloud files and directories (see Setting Strong Directory Permissions). This is an extremely important step. It helps protect your ownCloud installation, and ensures that it will run correctly.
