Install openQRM on Debian

This How-To explains installing the openQRM Datacentre Management and Cloud Computing platform on Debian. It is the starting point for a set of openQRM How-Tos explaining different Use-cases with the focus on virtualisation, automation and cloud computing.

Requirements

• One physical Server. Alternatively, the installation can be also done within a Virtual Machine
• At least 1 GB of Memory
• at least 40 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

1. Install a minimal Debian on a physical Server. During the installation select 'manual network' configuration and provide a static IP address. In this tutorial we will use 192.168.178.5/255.255.255.0 as the IP configuration for the openQRM Server system.
2. Remember to use/set a Fully Qualified Domain Name (FQDN) as the sytem's hostname and domain. It does not need to resolve, but its important to be set.
3. In the partitioning setup, 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'.
4. In the software selection dialog select just 'SSH-Server'
5. After the installation finished please login to the system and update its packaging system as 'root':

apt-get update && apt-get upgrade

Install openQRM - the short version

1. download and un-compress openQRM Community or Enterprise to /usr/src

2. un tar and install ;

Community;

tar -zxf openQRM-5.3.50-Community-Edition.tgz ; cd openQRM-5.3.50-Community-Edition/ ; ./install-openqrm.sh

Enterprise;

tar -zxf openQRM-5.3.50-Enterprise-Edition.tgz ; cd openQRM-5.3.50-Enterprise-Edition/ ; ./install-openqrm.sh

This process can take a short while, whilst it installs the supporting openQRM packages. Minimum 10 minutes if you have fast internet and a decent kvm.

4. suggestion: add PVE kernel to KVM first, if used in conjunction with a Proxmox VE installation,

wget http://download.proxmox.com/debian/dists/bullseye/pve-no-subscription/binary-amd64/pve-kernel-5.11.22-3-pve_5.11.22-7_amd64.deb

5. create mysql openqrm user and password, flush privileges

mysql -e "grant all on openqrm.* to 'openqrm'@'localhost' identified by 'openqrm'; flush privileges"

6. reboot, this is useful to the current KVM kernel (now the pve kernel) will be used as the default linux kernel.

7. then configure openqrm via web (remember the steps above the username and password are both openqrm), the last screen will take 5-10 minutes whilst openQRM rebuilds the current kernel's initrd into an openQRM compabille boot

Install openQRM - the longer version

Purchase and download openQRM

openQRM is available from openQRM Enterprise at

http://www.openqrm-enterprise.com/

You can also use the instructions below to install openQRM from the source repository or by packages.

The installation procedure for openQRM is straight forward.

1. Unpack the openqrm-enterprise.tar.gz file:

tar -xvzf openqrm-enterprise.tar.gz

2. Then run as 'root'

cd openqrm-enterprise ./install-openqrm.sh

Make sure to set a password for the mysql-server and nagios4 package.

Setting a password

The installation also asks for the mail-configuration. If unsure please select "local only" and go on with the suggested system name.

Mail-Configuration

The last step of the installation provides you with the URL, username and password to login to the openQRM Server

openQRM login credentials

Installation by packages

To install openQRM by distribution packages please request the package installation from openQRM Enterprise

Configure and initialize openQRM

After a successful installation the openQRM Server web interface is available at

http://static-ip-configured-during-the-Debian-installation/openqrm

If you have set the suggested IP address for this howto the openQRM URL will be

http://192.168.178.5/openqrm

Open this URL in your Web browser. Login with the username 'openqrm' and the password 'openqrm'. Then select the network interface to use for the openQRM management network

Network Interface selection screen

Then select 'mysql' as the database type

Database type selection

At the next step, provide the database credentials. Ensure the database credentials are valid before proceeding. Please note this stage can take up to 8 minutes. The screen will be blank, please be patient. You can always;

tail -n 100 -f /var/log/syslog

for activity.

Database configuration

For the openQRM Enterprise Edition, the following page provides an simple option to upload the licence keys

Upload licence keys

Once the license keys are provided openQRM will rebuild the current kernel into an openQRM initramdisk, this may take 5-10 minutes.

Congratulations!!

openQRM is now installed and successfully initialized ready to manage all aspects of your datacentre

Note Well:

It is always wise to install a duplicate kernel (this process can take 5-10mins or more on slower computers);

To add the Kernel to openQRM. Replace KERNEL_NAME, KERNEL_VER, OPENQRM_UI_USER, OPENQRM_UI_PASS, SERVER_NAME with the appropriate variables

1. /usr/share/openqrm/bin/openqrm kernel add -n KERNEL_NAME -v KERNEL_VER -u OPENQRM_UI_USER -p OPENQRM_UI_PASS -l / -i initramfs -m csiostor
2. /usr/share/openqrm/bin/openqrm kernel add -n pve-5.11.22-6 -v 5.11.22-3-pve -u openqrm -p openqrm -l / -i initramfs -m csiostor
