This How-To 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 (password: openqrm) and run "ifconfig -a"

1. Install a physical System with Debian as KVM Host

Install a minimal Debian on a physical Server.

2. Unpack the openQRM Enterprise Appliance and run the installer

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

Unpack openQRM Enterprise Appliance

Now open a browser to http://[ip-address-of-the-openqrm-appliance]/openqrm

Open Browser

On initial start the License manager will appear. Please select the license files and submit

Select licence files

Your openQRM Enterprise Appliance is up and running!

3. 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 in section 2 on a second system. Please make sure to use the exact same MAC address for the openQRM Enterprise Appliance as for the first node.

Use same MAC address

However, 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.

Select No

After the installation on the second system, do NOT start the openQRM Enterprise Appliance

Do not start Appliance

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

Run on first system

Press ENTER on the welcome screen

Press Enter

Accept the openQRM Enterprise License agreement

Accept Agreement

After the HA setup is finished, provide the hostname of the first system

Provide hostname

Provide the IP address of the first system

Provide IP address

NOTE If the /etc/hosts entry does not exist yet, the installer will notify about it and suggest a solution. Please confirm the /etc/hosts adaptions

Confirm adaptations

Now provide the hostname of the second system

Provide hostname

And the IP address of the second system

Provide IP address

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

System will now be added to /etc/hosts

Please confirm the /etc/hosts adaptions

Confirm adaptations

Successfully setup on the first system

Setup is successful

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!

Starting Graphical HA Manager

Repeat steps in section 3 on the second system.


Here "crm_mon" after setting up the second system. Note that both systems should be in the "Online" line.

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

Run HA manager on one of the two nodes

Accept the ssh-key fingerprints

Login as "root" with the password "openqrm"

Login

The openQRM Enterprise HA Cluster will open in the overview. With a right-click on the "openqrm-appliance" resource you can manage it e.g. migrate it to the other system.
