Howto: Install openQRM on Debian

This HowTo is about how to install the openQRM Datacenter Management and Cloud Computing platform on Debian. It is the starting point for a set of openQRM HowTos explaining different Use-cases with the focus on virtualization, automation and cloud computing.


  • One physical Server. Alternatively the installation can be also done within a Virtual Machine
  • at least 1 GB of Memory
  • at least 100 GB of Diskspace
  • optional VT for Intel CPUs or AMD-V for AMD CPUs (Virtualization Technology) enabled in the Systems BIOS so that the openQRM Server can run Virtual Machines later

Install Debian Wheezy

Install a minimal Debian on a physical Server. During the installation select 'manual network' configuration and provide a static IP address.

In this Howto we will use as the IP configuration for the openQRM Server system.

In the partitioning setup please select 'manual' and create one partition for the root-filesystem, one as swap space plus a dedicated partition to be used as storage space for the Virtual Machines later. In the configuration of the dedicated storage partition select 'do not use'.

In the software selection dialog select just 'SSH-Server'

After the installation finished please login to the system and update its packaging system as 'root'

apt-get update && apt-get upgrade


Please notice!

In the recent Debian updates the /etc/php5/apache2/php.ini configuration derective "disable_functions" changed and includes now a bunch of functions disabled by default. Please open /etc/php5/apache2/php.ini in your favourite editor and search for "disable_functions". Then remove ALL functions from the "disable_functions" PHP configuration paramter for Apache!

It should look likt this:

disable_functions = ""

Then restart Apache by

/etc/init.d/apache2 restart
