What Is a Linux Administrator?

December 5, 2024

More technology runs on Linux than you probably realize. It’s very likely that everything from the car you drive to the video games you play at home runs on Linux, even your favorite online shopping destination. It’s incorporated everywhere, so it’s no surprise that people who know this operating system backward and forward are of great value to many organizations. If you have these skills, a role as a Linux administrator could be your next move.

What is a Linux administrator?

A Linux administrator is a back-end IT specialist who installs, configures, and maintains Linux operating systems in the following ways:

  • Installs and configures Linux systems, including back-end databases and scripts
  • Performs system maintenance by reviewing error logs
  • Creates system backups
  • Monitors system performance to prevent slowdowns and crashes
  • Provides technical support
  • Maintains system security

A Linux administrator is an important IT team member at any organization but is generally found in medium to large organizations. They are responsible for completing routine security audits and administrative scripting using computer languages such as Perl, Python, and Shell. The Linux administrator is often the point person between the organization and the end user and coordinates internal teams to drive projects and improvements.

How to become a Linux administrator

Most companies looking for a Linux administrator require a bachelor’s degree in computer science or a related field. Many organizations also want a relevant Linux certification to validate a candidate’s training and knowledge of Linux operating systems.

However, understanding Linux is not the only skill needed for this position. Qualified Linux administrators will also have skills in application development, systems hardware, web services, Python, Windows, and SQL.

Also, you can’t forget about troubleshooting and communication skills. Since the role of a Linux administrator is part technical guru and part people manager, these skills are just as important.

Certifications like CompTIA Network+ and CompTIA Linux+ can set you on the right path to becoming a Linux administrator.

CompTIA Network+ helps develop a career in IT infrastructure, covering troubleshooting, configuring, and managing networks. It would help if you became CompTIA Network+ certified or have equivalent knowledge and experience before pursuing CompTIA Linux+.

CompTIA Linux+ validates the skills of IT pros with hands-on experience configuring, monitoring, and supporting servers running on the Linux operating system.

The exam focuses on the following skills:

  • Security
  • Kernel modules
  • Storage and virtualization
  • Device management at the enterprise level
  • Git and automation
  • Networking and firewalls
  • Server side and command line
  • Sever coverage
  • Troubleshooting
  • SELinux

In addition to certifications, CompTIA offers a full suite of training products to help you learn the technical and professional skills necessary to become a Linux administrator. Check out the CompTIA Career Roadmap to see what other certifications can help you land this role.
