The openQRM Enterprise Appliance - regular and high-availability mode

This HowTo is about how to easily setup the openQRM Enterprise Appliance in regular and high-availability mode.

openQRM Enterprise Appliance network configuration

System User: root
Password: openqrm

openQRM UI User: openqrm
Password: openqrm

First network card: dhcpd
Virtual openQRM interface: static IP 192.168.11.2 (Class C)

In most cases (depending on your network infra-structure) the openQRM Enterprise Appliance will automatically get an IP address from a "dhcpd" server in your network. To check which IP address it got please use a VNC-viewer to login to the VM console, login as root (passowrd: openqrm) and run "ifconfig -a"

Install a physical System with Debian as KVM Host

Install a minimal Debian on a physical Server.

Unpack the openQRM Enterprise Appliance and run the installer

In a console as root user please unpack the openQRM Enterprise Appliance and run the installier

openQRM Enterprise Appliance High-Availability Setup

To use the openQRM Enterprise Appliance in High-Availability mode a second physical system is required. Both system must have shared (or distributed) storage location used to store the openQRM Enterprise Appliance VM. Simply install the openQRM Enterprise on both systems with the same configuration and choose the shared (or distributed) storage to store the openQRM Enterprise Appliance VM. Also make sure to use exact the same MAC address for the installation on both systems.

Repeat the steps above on a second system. Please make sure to use the exact same MAC address for the openQRM Enterprise Appliance as for the first node.



On the second system the installer will detect that the openQRM Enterprise Appliance VM is already existing on the shared storage location. Please select "No" to not overwrite it.



After the installation on the second system please do NOT star the openQRM Enterprise Appliance



On the first system please run the "openQRM-Enterprise-Appliance-HA-cluster-setup"



Press ENTER on the welcome screen



Accept the openQRM Enterprise License agreement





Preparing the HA setup



Provide the hostname of the first system



Provide the IP address of the first system



If the /etc/hosts entry are not existing yet the installer will notify about it ...



... and suggest a solution



Please confirm the /etc/hosts adaptions





Now provide the hostname of the second system



And the IP address of the second system



The second system is now going to be added to /etc/hosts



Please confirm the /etc/hosts adaptions





Successfully setup on the first system



Here the installer removes the openQRM Enterprise Appliance from regular init since it will be managed by "corosync/pacemaker" now.



To start a graphical High-availability Manager please run on one of the two nodes: "openQRM-Enterprise-Appliance-HA-cluster-admin"
Please notice that this will require either a graphical Desktop setup or X-forwarding!



Here the console view of "crm_mon"



Now please repeat those HA-setup steps on the second system.



Here "crm_mon" after setting up the second system.



Starting the graphical High-availability Manager on one of the two nodes by running: "openQRM-Enterprise-Appliance-HA-cluster-admin. Click on "connect"



Accept the ssh-key fingerprints



Login as "root" with the password "openqrm"



The openQRM Enterprise HA Cluster overview



With a right-click on the "openqrm-appliance" resource you can manage it e.g. migrate it to the other system.
