Linux System Administration

As Linux continues to grow in market share as an enterprise operating system, system administrators need to solve problems in a wide range of applications and work environments. To help you get to the bottom of real- life problems quickly, Linux System Administration is organised around three common administration scenarios: Linux as a hub for a home or small office, Linux as LAMP system (Linux-Apache web server-MySQL database- PHP/Perl/Python scripting languages), and remote administration of Linux machines. Linux System Administration provides a solid background for Linux desktop users who want to move beyond the basics of Linux, and for experienced system administrators who are looking to gain more advanced skills.

Tom Adelstein works as a system administrator and a technical writer. He became a young author by accident in 1985 and has written prolifically ever since. Tom's career began in public accounting and investment banking where he excelled by using computer technology to help his companies become industry leaders in the financial service sector. In 1993, he decided to change industries completely to pursue information technology full time. He says he chose to follow his heart instead of his head.
