Configuring the cluster administrator machine


As we have mentioned previously, the most efficient way to install Linux on a large number of machines is to install over the network. In this book, we assume to use the administrator machine as the installation server. We will learn steps to configure this server, including the configuration of the following two services: DHCP and FTP.

Getting ready

Before getting started, we assume that the cluster administrator machine has a 64 bit Red Hat compatible Linux operating system installed. The hostname of the machine is hadoop.admin and an administrative user hdadmin has been created. This user should have sudo privileges to install software packages, configure system services, and so on. We also assume administrative tools such as a command-line text editor has been installed on this machine. We will use these tools and commands directly in the upcoming recipes.

Tip

In this book, we assume to use CentOS 6.3 (which corresponds to Red Hat Enterprise...
