I recently posted a question regarding the issue of loadbalancing webservers on a budget. It's finally time to begin the testing so I thought about setting up two or more Ubuntu VM's in my LAN running pacemaker+corosync in order to learn the basics and try different configs out.
How do I get started after installing both corosync + pacemaker as I don't have public IP's attached to each VM living in my LAN?
You can use RFC1918 IP addresses to test your configuration. Depending on the load balancing setup, the use of RFC1918 addresses may continue in some form into production.
