Introduction to systemd and Managing Services on Linux

systemd is the system and service manager running on most modern Linux distributions, controlling how background services (like your web server or database) start and stop.

Essential Commands

systemctl status nginx checks if a service is running, systemctl restart mysql restarts one, and systemctl enable makes sure a service starts automatically on boot.

Why It Matters

When troubleshooting a site that's suddenly down, checking whether the relevant service (web server, database) is actually running is often the fastest first diagnostic step.
