• Synchronized cloud storage on your hardware
• Virtualmin Pro has install script

We use the apt package manager to install and maintain OwnCloud.

https://doc.owncloud.org/server/9.1/admin_manual/maintenance/package_upgrade.html

https://doc.owncloud.org/server/9.0/admin_manual/maintenance/update.html

as root:

apt-get -y update && apt-get -y dist-upgrade && apt-get -y autoremove && reboot

Upgrading OwnCloud will leave the installation in Maintenance Mode.

Then, after logging back in as root:

cd /var/www/owncloud/
sudo -u www-data php occ upgrade
sudo -u www-data php occ maintenance:mode --off

Smaller installations can just use SQLite database for simplicity.

Virtualmin → <domain> → Install Scripts → Available Scripts → OwnCloud

1. Browse to the OwnCloud URL

Reset permissions for better security:

find /var/www/owncloud -type d -exec chmod 775 {} \;
find /var/www/owncloud -type f -exec chmod 664 {} \;
chown -R root:root /var/www/owncloud
chown -R www-data.www-data /var/www/owncloud/config
chown -R www-data.www-data /var/www/owncloud/data
chown -R www-data.www-data /var/www/owncloud/apps
chown root.root /var/www/owncloud/.htaccess
chown root.root /var/www/owncloud/config/.htaccess
chown root.root /var/www/owncloud/data/.htaccess
chcon -R -t httpd_sys_rw_content_t /var/www/owncloud/config
chcon -R -t httpd_sys_rw_content_t /var/www/owncloud/data
chcon -R -t httpd_sys_rw_content_t /var/www/owncloud/apps

Here we mount an NFS share as the OwnCloud data store:

mount -t nfs ip.of.nfs.svr:/path/to/owncloud /mnt/

rsync -avr /var/www/html/owncloud/data/* /mnt/

umount /mnt/

Make it survive a reboot:

vim /etc/fstab

# Mount the NFS data store
ip.of.nfs.svr:/path/to/owncloud        /var/www/html/owncloud/data/  nfs  _netdev,context="system_u:object_r:httpd_sys_rw_content_t:s0"  0 0

mount -a
mount
