This course will teach you the skills and processes you need to work as a professional Linux systems administrator.

Who Is It For

The course is ideal for those new to IT, or those who have worked with operating systems other than Linux and want to move into a career administering Linux systems.

Prerequisites
Basic knowledge of Linux, including installing Linux and using the command line is helpful, but not required. If you don’t have any Linux experience, we highly recommend the free Introduction to Linux course on edX.
Lab Info
Lab exercises in this course are designed to work either on native hardware, or using a virtual machine (VM), under a hypervisor, such as those in the KVM, VMWare, or Virtual Box families. Detailed instructions to set up your lab environment are provided in the course.
Reviews

It is the first time I have a general introduction to the Linux OS, and I feel more confident after the course.
Jan 2021
It covers all that is needed for the exam, and gives an additional level of Linux administration that other Linux courses don't.

The things I learn here are not easily found online. The learning path carved contains well structured contents that allows one to properly administer and use a Linux system. Fundamentals of why a technology is used is also explained, which is always the key part of rooting any new knowledge in a beginner.

Vendor neutrality, covers more than one distribution where possible. Clear and concise explanations of features and commands, plus the reasons *why* they would be used.

I loved the labs. Any chance to actually put what I am learning to use is very helpful. Sometimes I think I am understanding a subject, but when I get to a lab I realize I have to try to understand it more. In addition, it allows me to say, yes I get that now.
Sep 2020
I like how modular it is, that I can pop in, run through a chapter rather quickly, and then pop out. I also like that the labs are downloadable pdfs, as I sometimes take the course on a Windows laptop with a Linux VM, and other times log in on a Linux PC.
Aug 2020
There was a lot of depth in the course content, with practical examples. Most of the subject areas were explained clearly. The online support was prompt and helpful.
Aug 2021
Although I found out that using a Linux operating system is not easy, this course has many parts that are easy to practice, and has provided all the instructions necessary to handle many situations.
Aug 2020
I liked that each chapter was short, so I could commit to doing one at a time. I enjoyed the quizzes as a knowledge check and motivational reward for finishing each section. I love the UI improvements that just came out (I used the platform before and after and I enjoyed the improvement!)
Aug 2020
The content is up-to-date. There are practical examples that are useful for everyday duties. The labs are great. The setup script for the course was very useful. It is vendor neutral.

For someone planning on becoming a Linux administrator I feel they will need more details, and Linux is not intuitive to learn, meaning you need a lot of guidance to find your way around, and this course certainly helps. The exercises at the end of each chapter were useful, and I saved a lot for future reference. I'm only a casual Linux user, and the content was useful.
Jul 2020
No stone left unturned. The demo videos really helped for a big picture perspective, and brought abstract concepts to life. I also enjoyed that I could review anything I missed at the end of chapter quizzes.
May 2020
I thought that the order in which things were presented was conducive to getting things well sorted and into long term memory.
May 2020
Focus on practical scenarios over raw theory with real-life examples.
May 2020
The course was very well planned with sequential learning goals.
Feb 2020
I liked that it opens your mind to possibilities, each chapter was well designed to of course give the introduction to each specific topic. After taking this course I discovered Linux is huge, and being able to create a course I believe was a bit of a challenge, but in the end I recognize and congratulate all people involved in creating it to spread the knowledge and continue to contribute to the open source community.
