Introduction

Using Red Hat Enterprise Linux, it is possible to create highly available server clustering solutions able to withstand many common hardware and software failures with little or no interruption of critical services. By allowing multiple computers to work together in offering these critical services, system administrators can plan and execute system maintenance and upgrades without service interruption.

This book guides you through the following steps in understanding and deploying a Red Hat Enterprise Linux Linux Virtual Server (LVS) technology:

  • Explains the Linux Virtual Server technology used by Red Hat Enterprise Linux to create a load-balancing cluster

  • Explains how to configure a Red Hat Enterprise Linux LVS cluster

  • Guides you through the Piranha Configuration Tool, a graphical interface used for configuring and monitoring an LVS cluster
