Welcome to the Red Hat Enterprise Linux
Introduction to System Administration.
The Red Hat Enterprise Linux Introduction
to System Administration contains introductory information for
new Red Hat Enterprise Linux system administrators. It does
not teach you how to perform a particular
task under Red Hat Enterprise Linux; rather, it provides you with
the background knowledge that more experienced system
administrators have learned over time.
This guide assumes you have a limited amount of experience as a
Linux user, but no Linux system administration experience. If you
are completely new to Linux in general (and Red Hat Enterprise
Linux in particular), you should start by purchasing an
introductory book on Linux.
Each chapter in the Red Hat Enterprise
Linux Introduction to System Administration has the following
Generic overview material — This section discusses the
topic of the chapter without going into details about a specific
operating system, technology, or methodology.
Red Hat Enterprise Linux-specific material — This section
addresses aspects of the topic related to Linux in general and Red
Hat Enterprise Linux in particular.
Additional resources for further study — This section
includes pointers to other Red Hat Enterprise Linux manuals,
helpful websites, and books containing information applicable to
By adopting a consistent structure, readers can more easily read
the Red Hat Enterprise Linux Introduction to
System Administration in whatever way they choose. For example,
an experienced system administrator with little Red Hat Enterprise
Linux experience could skim only the sections that specifically
focus on Red Hat Enterprise Linux, while a new system adminstrator
could start by reading only the generic overview sections, and
using the Red Hat Enterprise Linux-specific sections as an
introduction to more in-depth resources.
While on the subject of more in-depth resources, the Red Hat Enterprise Linux System Administration
Guide is an excellent resource for performing specific tasks in
a Red Hat Enterprise Linux environment. Administrators requiring
more in-depth, factual information should refer to the Red Hat Enterprise Linux Reference Guide.
HTML, PDF, and RPM versions of the manuals are available on the
Red Hat Enterprise Linux Documentation CD and online at https://www.redhat.com/docs/.
Although this manual reflects the most current information
possible, read the Red Hat Enterprise Linux
Release Notes for information that may not have been available
prior to our documentation being finalized. They can be found on
the Red Hat Enterprise Linux CD #1 and online at https://www.redhat.com/docs/.
