## Systemd Service
Two paths are available depending on your comfort level with Linux system administration.
### Simple install (recommended for most users)
Run the installer script from the repo root. It runs as your current user, installs from wherever you cloned the repo, and prints a quick-reference cheatsheet when done — no separate service account or path juggling required.
```bash
bash scripts/install_service.sh
```
The script interactively asks which transport to use (serial auto-detect, serial with explicit port, TCP, or BLE), whether to enable the bot system, and whether to set up HTTP Basic Auth. It handles dependency installation (`uv sync`), fetches a prebuilt frontend, adds your user to the `dialout` group if needed, writes the systemd unit file, and enables the service. After installation, normal operations work without any `sudo -u` gymnastics:
```bash
# Update to latest and restart
cd /path/to/repo
git pull
uv sync
cd frontend && npm install && npm run build && cd ..
sudo systemctl restart remoteterm
# Refresh prebuilt frontend only (skips local build)
python3 scripts/fetch_prebuilt_frontend.py
sudo systemctl restart remoteterm
# View live logs
sudo journalctl -u remoteterm -f
# Service control
sudo systemctl start|stop|restart|status remoteterm
```
### Hardened install (production / multi-user systems)
Assumes you are running from `/opt/remoteterm`; adjust paths if you deploy elsewhere.
