Configure Apache for ownCloud

When ownCloud is installed, it places its web files under the /var/www/owncloud directory.

In order to configure Apache to server the ownCloud content, you need to create ownCloud Apache configuration file where you can define the ownCloud directory as your root directory.

Copy and paste the command below to create owncloud.conf configuration file.

cat > /etc/apache2/sites-available/owncloud.conf << 'EOL'
Alias / "/var/www/owncloud/"

<Directory /var/www/owncloud/>
  Options +FollowSymlinks
  AllowOverride All

 <IfModule mod_dav.c>
  Dav off

 SetEnv HOME /var/www/owncloud
 SetEnv HTTP_HOME /var/www/owncloud


Verify Apache configuration syntax.

apachectl -t

Enable ownCloud site.

a2ensite owncloud.conf

Disable default Apache site;

a2dissite 000-default.conf

Enable additional recommended Apache modules.

a2enmod rewrite mime unique_id php

Restart Apache if the configuration is fine.

systemctl restart apache2

Create ownCloud Database and User

Run the mysql_secure_installation script to remove test databases, disable remote root login e.t.c.


Login to MariaDB database server and create ownCloud database and database user.


If you already enabled password authentication, then login via;

  1. Ahoi. I’ve tried this on a Debian 11 and got stuck at this point.

    root@owncloud-new:~# apt update
    Get:2 InRelease [1,527 B]
    Hit:3 bullseye-security InRelease
    Hit:4 bullseye InRelease
    Hit:5 bullseye-updates InRelease
    Get:1 InRelease
    Err:1 InRelease
    Clearsigned file isn’t valid, got ‘NOSPLIT’ (does the network require authentication?)
    Reading package lists… Done
    E: Failed to fetch Clearsigned file isn’t valid, got ‘NOSPLIT’ (does the network require authentication?)
    E: The repository ‘ InRelease’ is not signed.
    N: Updating from such a repository can’t be done securely, and is therefore disabled by default.
    N: See apt-secure(8) manpage for repository creation and user configuration details.

    Any Idea how to fix this.
