Achieve Linux system administration mastery with time-tested and proven techniques 

In Mastering Linux System Administration, Linux experts and system administrators Christine Bresnahan and Richard Blum deliver a comprehensive roadmap to go from Linux beginner to expert Linux system administrator with a learning-by-doing approach. Organized by do-it-yourself tasks, the book includes instructor materials like a sample syllabus, additional review questions, and slide decks. 

Amongst the practical applications of the Linux operating system included within, you’ll find detailed and easy-to-follow instruction on: 

  • Installing Linux servers, understanding the boot and initialization processes, managing hardware, and working with networks 
  • Accessing the Linux command line, working with the virtual directory structure, and creating shell scripts to automate administrative tasks 
  • Managing Linux user accounts, system security, web and database servers, and virtualization environments 

Perfect for entry-level Linux system administrators, as well as system administrators familiar with Windows, Mac, NetWare, or other UNIX systems, Mastering Linux System Administration is a must-read guide to manage and secure Linux servers.
