Manage Processes and Jobs on a Linux Server (XK0-006)

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

  • 2.3: Given a scenario, manage processes and jobs in a Linux environment.
  • 5.2: Given a scenario, analyze and troubleshoot hardware, storage, and Linux OS issues.
  • 5.5: Given a scenario, analyze and troubleshoot performance issues.

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

  • Use process verification tools including /proc, ps, top, htop, lsof, and strace to inspect running processes.
  • Identify and describe the key Linux process states including running, sleeping, stopped, and zombie.
  • Adjust process priority using nice and renice to influence CPU scheduling.
  • Manage foreground and background jobs using fg, bg, jobs, kill, killall, pkill, and nohup.

Overview

Welcome to the Manage Processes and Jobs on a Linux Server lab. In this lab, you will work with the tools and techniques used to monitor, control, and influence running processes on a Linux system. You will begin with a reading assignment that introduces how system performance is impacted by CPU, memory, disk I/O, and process behavior, and how resource constraints can lead to degraded system responsiveness.

You will then create a custom service to use as a consistent target throughout the lab and use process inspection tools to analyze it. As you progress, you will observe process state transitions, explore how niceness values affect CPU scheduling, and manage foreground and background jobs using standard shell and signal commands.

By the end of this lab, you will be able to monitor system performance, identify resource-related issues, and manage processes and jobs confidently in real-world Linux administration scenarios.

In this lab, you will complete the following five activities:

  • Reading Assignment - Performance and Resource in Linux
  • Exercise 1 – Exploring Process Verification Tools
  • Exercise 2 – Introduction to Linux Process States
  • Exercise 3 – Linux Process Priority and Niceness
  • Exercise 4 – Job and Process Management in Linux
