The second of the two-part Scalable Linux Clusters article. This second part features the addition of Heartbeat and ldirectord to the network started in Part I.

Whether you are perusing mailing lists or reading the large LVS-HOWTO, much of the available information on creating a high-availability Linux cluster can be difficult to sift through.

This two-part article attempts to present an up-to-date tutorial on setting up LVS for your network, with an emphasis on designing a system that matches your infrastructure’s needs.
