Introduction

Scyld ClusterWare is supported on Red Hat Enterprise Linux 5 (RHEL5) and CentOS 5. This document describes installing on Red Hat, though installing on CentOS will be identical, except where explicitly noted. Scyld ClusterWare is installed on the master node after installing a RHEL5 or CentOS 5 base distribution. You must configure your network interface and network security settings to support Scyld ClusterWare.

The compute nodes join the cluster without any explicit installation. Having obtained a boot image via either PXE or local media, the nodes are converted to a Scyld-developed network boot system and seamlessly appear as part of a virtual parallel computer.

This chapter introduces you to the Scyld ClusterWare installation procedures, highlights the important steps in the Red Hat installation that require special attention, and then steps you through the installation process. Installation is done using the /usr/bin/yum command, installing from a repository of rpms, typically across a network connection. See the Chapter called Detailed Installation Instructions for more detailed instructions. Refer to the Red Hat documentation for information on installing RHEL5.
