Welcome to the Red Hat Enterprise Linux Introduction to System Adminitration.
The Red Hat Enterprise Linux Introduction to System Adminitration 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 Adminitration has the following structure:
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 the topic.
By adopting a consistent structure, readers can more easily read the Red Hat Enterprise Linux Introduction to System Adminitration 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 System Administrators 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 Reference Guide.
