Foundations of CentOS Linux:
Enterprise Linux On the Cheap
Dear Reader,
Chivas Sicam
I’ve been using Linux for years for software development, for personal enter-
tainment, and to create servers to be deployed on the network. But when asked
on which distribution I always use when creating and deploying network serv-
ers, I always say CentOS. With CentOS, I have all the tools that I need to do tasks
with Linux, from command-line shell scripting to graphical systems adminis-
tration with virtualization.
The book you are holding now contains expert advice that will help you
learn Linux administration with the CentOS distribution. You will be able to
write shell scripts, schedule automated tasks and use the GNOME desktop.
For network servers, you will learn how to properly install and configure file
sharing and print servers, combine servers with directory services for unified
authentication, and use virtualization to save on hardware costs.
With this book, you have a concrete starting guide to learning Linux with
CentOS. You will spend less time asking questions and more time to build-
ing whatever you need with CentOS as you learn about it with this book. If
you have plans of becoming an RHCE (Red Hat Certified Engineer), what you
have learned here will give you a boost in studying review materials for the
RHCE exam.
I hope that you will enjoy learning Linux with CentOS and use it to create
masterpiece servers with this book.

For my granddad, Bill “Pappy” Membrey. Without his unwavering support and guidance (not
