Best Linux Certs for Beginner Sysadmins - Linux Plus

It’s no secret that the IT industry has opportunities aplenty for those who know their way around Linux. From sprawling data centers to boutique developer studios, Linux system administrators — or “sysadmins” — form part of an essential workforce that keeps businesses, and the software that powers them, running smoothly and efficiently.

Yet, for many junior Linux sysadmins who are just now stepping into the field, it can be tough to get a foot in the door without proof that you know your stuff.

This article will help you decide your next move towards career success by covering six of the best Linux certifications for beginner sysadmins in 2023 and beyond.

Because Linux OS’s are free to use, anyone can make a start on their career by bootstrapping on a shoe-string budget — i.e. with nothing more than a PC and a free copy of a Linux-based distribution such as Ubuntu, Debian, CentOS, or Red Hat.

And because of its open source nature, Linux users can tinker and tweak the OS to their heart’s content, making it easy to become an expert through pure experience and a dash of curiosity.

These factors (coupled with an overall average salary of $93,430) make Linux system administration an attractive career choice for those heading into the world of professional IT work without a college degree or extensive mentorship. However, even though practical experience is a huge bonus on your resume — and something that employers will look for when evaluating Linux sysadmin candidates — industry certifications remain the gold standard when it comes to proving that you can handle an organization’s IT systems.

As a beginner Linux system administrator, there are several authoritative Linux certs you can choose from to get your career in gear. Our picks of the top Linux certifications for junior sysadmins, based on current trends and forecasts include:

  1. CompTIA Linux+
  2. LPIC-1: Linux Administrator
  3. LFCS: Linux Foundation Certified System Administrator
  4. RHCSA: Red Hat Certified System Administrator
  5. SCA: SUSE Certified Administrator
