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.
