Essentials of System Administration


Linux is the #1 operating system for web servers, cloud computing, smart phones and consumer electronics. Due to its rapid adoption, there's a shortage of Linux system administrators. According to the 2015 Linux Jobs Report, "the unstoppable Linux job market shows no sign of slowing down." The Linux Foundation has created a career entry training and certification path that is 100% online, highly respected and exceptionally affordable.


Who should attend

Anybody interested in acquiring or polishing professional Linux system administration skills, or looking for preparation for the Linux Foundation Certified System Administrator exam.


Basic knowledge of Linux, including installing Linux and using the command line is helpful but not required. Our free LFS101x Introduction to Linux course is useful preparation for this course.

Course Objectives

This course will teach you the concepts and skills you need to be prepared for the Linux Foundation Certified System Administrator exam. You’ll learn how to administer, configure and upgrade Linux systems running one of the three major Linux distribution families (Red Hat, SUSE, Debian/Ubuntu). You’ll also learn all the tools and concepts you need to efficiently build and manage a production Linux infrastructure.

This course is designed to work with a wide range of Linux distributions, so you will be able to apply these concepts regardless of your distro.

You will have access to the course for a full year from the date of purchase, regardless of how quickly you complete the course. You can expect the course to take 40-50 hours to complete (although the course is self-paced, so you can move as quickly or as slowly as you like).
