Master Linux system administration hands-on — and walk out ready for the CompTIA Linux+ XK0-006 exam.
This 5-day course teaches you to configure, manage, secure, automate and troubleshoot Linux servers, mapped 1:1 to the five CompTIA Linux+ XK0-006 (V8) exam domains. It is built for system administrators, DevOps engineers, cloud engineers and IT professionals who want job-ready Linux skills plus a clear path to the Linux+ certification.
Every one of the 30 step-by-step labs runs free in the browser on the Killercoda Ubuntu Playground — no local install, no virtual machine, no credit card required.
| # | Learning Outcome |
|---|---|
| LO1 | Explain core Linux concepts — boot process, Filesystem Hierarchy Standard, device management and virtualization — and manage storage, networking and shell operations. |
| LO2 | Manage files, local user and group accounts, processes and jobs, software packages, systemd services and containerized applications on a Linux server. |
| LO3 | Apply Linux security: authentication/authorization (sudo, PAM), firewalls, OS and account hardening, cryptography and compliance/audit procedures. |
| LO4 | Automate administration with Ansible, Bash and Python, apply Git version control, and use AI assistants responsibly and securely. |
| LO5 | Monitor a Linux system and analyze and troubleshoot hardware, storage, network, security and performance issues using the right diagnostic tools. |
The course follows the XK0-006 exam blueprint. Each lab has its own folder under labs/ with a full step-by-step README.md.
