Beginner to Intermediate 8 Weeks 10 Modules Online / Classroom Linux Server Setup Project

Course overview

Linux is widely used for servers, cloud infrastructure, containers, development environments, and DevOps workflows. Linux administration involves managing users, files, permissions, processes, services, networks, storage, security, and system performance.

This course introduces Linux fundamentals, terminal usage, file systems, users and groups, permissions, package management, processes, systemd services, networking, SSH, storage, shell scripting, logs, monitoring, backups, and basic server hardening.

The proposed capstone is a Linux Server Setup project for a chosen approved use case. It covers server preparation, user management, service deployment, firewall configuration, backups, monitoring, and documentation.

A well-managed Linux server should use least-privilege access, regular updates, controlled services, monitoring, backups, and documented recovery procedures.

Capstone project

Linux Server Setup

Build a complete Linux Server Setup for a chosen approved use case. Possible examples include a web server, file server, backup server, monitoring server, development server, or another suitable educational server environment.

Core project requirements

  • Define the server purpose, users, and required services.
  • Prepare an approved Linux server or virtual machine.
  • Update the system and install required packages.
  • Create administrative and service-specific user accounts.
  • Configure appropriate users, groups, and permissions.
  • Deploy at least one approved service or application.
  • Configure the service to start automatically.
  • Configure SSH access using secure practices.
  • Configure a firewall with only required ports open.
  • Create a backup script and schedule it using cron.
  • Monitor CPU, memory, disk, and service health.
  • Document setup, configuration, recovery, and maintenance steps.

Quality requirements

  • Use least-privilege user accounts and permissions.
  • Do not use the root account for everyday administration.
  • Use SSH key-based authentication where supported.
  • Do not expose unnecessary ports or services.
  • Keep the system and packages updated.
  • Use approved repositories and software sources only.
  • Store backups securely and test restoration procedures.
  • Use clear logging and monitoring practices.
  • Do not store passwords, private keys, or secrets in public files.
