Manage a Linux Server Using systemd (XK0-006)

This lab aligns to the following CompTIA Linux+ (XK0-006) exam objectives:

  • 2.5: Given a scenario, manage Linux using systemd
  • 5.2: Given a scenario, analyze and troubleshoot hardware, storage, and Linux OS issues
  • 5.3: Given a scenario, analyze and troubleshoot networking issues on a Linux system

By the end of this lab, you will be able to: 

  • Identify and describe the key systemd unit types used in Linux service management.

  • Control service states using systemctl, including start, stop, restart, enable, disable, mask, and unmask.

  • Create and manage a custom systemd service unit.

  • Use core Linux system utilities including hostnamectl, resolvectl, sysctl, systemd-analyze, timedatectl, and systemd-resolved.

  • Analyse and troubleshoot Linux operating system issues.

Overview

Welcome to the Manage a Linux Server using systemd lab. 

In this lab, you will use systemd to control services, manage system states, and analyze system behavior on an Ubuntu system. You will explore how Linux systems transition from boot to a fully operational state, and how failures in services, dependencies, and system configuration can impact system stability.

Through hands-on tasks, you will examine systemd unit types, manage service lifecycles, and create a custom heartbeat service. You will also use core Linux utilities to inspect hostname configuration, analyze DNS resolution, review kernel parameters, evaluate boot performance, and manage time settings.

As you progress, you will apply troubleshooting concepts to identify issues related to service availability, network configuration, and name resolution, reinforcing how systemd and supporting tools are used to diagnose and resolve real-world system problems.

By the end of this lab, you will be able to confidently manage and troubleshoot a Linux server using systemd across both Ubuntu and AlmaLinux environments.

You will complete the following three activities in this lab:

  • Reading Assignment – Linux OS and Boot Process
  • Exercise 1 – Managing a Linux System with systemd
  • Exercise 2 – Working With Core Linux System Utilities
