systemd User Services

Core Idea

User services let your account run supervised processes without root access.

Practice Alone

Create this file at ~/.config/systemd/user/site.service, replacing 14567 with your computed port from the platform reference:

[Unit]
Description=Personal course site service

[Service]
WorkingDirectory=%h/public_html
ExecStart=/usr/bin/python3 -m http.server 14567 --bind 127.0.0.1

[Install]
WantedBy=default.target

Then operate it with user-scope systemd commands:

systemctl --user daemon-reload
systemctl --user enable --now site.service
systemctl --user status site.service
journalctl --user -u site.service --no-pager -n 50

Do not drop --user. Without it, you are asking for system services, not your account’s services.

Done When

systemctl --user status site.service shows an active service you understand.

• Service distinguishes network services, systemd services, user services, and system services.
• Logging explains how logs support debugging.
• Userspace explains why your service runs as your user rather than root.
• Process basics explains the running process behind the service.
• Kernel explains what still belongs to the operating system kernel.
• systemctl and journalctl are the command cards for operating services.
• Platform reference gives the service port formula and public URL shapes.
