systemd Service Units for anvilsrv

This directory contains systemd service unit files for running anvilsrv as a system service.

Service Files

1. anvilsrv-user.service - User Service (Recommended)

Run anvilsrv as a user service using systemd's user instance.

Installation:

# Copy the service file
mkdir -p ~/.config/systemd/user
cp services/systemd/anvilsrv-user.service ~/.config/systemd/user/

# Reload systemd user daemon
systemctl --user daemon-reload

# Enable and start the service
systemctl --user enable anvilsrv-user.service
systemctl --user start anvilsrv-user.service

# Check status
systemctl --user status anvilsrv-user.service

Management:

• Start: systemctl --user start anvilsrv-user
• Stop: systemctl --user stop anvilsrv-user
• Restart: systemctl --user restart anvilsrv-user
• Status: systemctl --user status anvilsrv-user
• Logs: journalctl --user -u anvilsrv-user -f
• Disable: systemctl --user disable anvilsrv-user

Enable Linger (Start on Boot):

To make the service start on system boot even when not logged in:

sudo loginctl enable-linger $USER

2. anvilsrv@.service - System Service Template

Run anvilsrv as a system service for specific users.

Installation:

# Copy the service file
sudo cp services/systemd/anvilsrv@.service /etc/systemd/system/

# Reload systemd daemon
sudo systemctl daemon-reload

# Enable and start for a specific user (replace 'username')
sudo systemctl enable anvilsrv@username.service
sudo systemctl start anvilsrv@username.service

# Check status
sudo systemctl status anvilsrv@username.service

Management:

• Start: sudo systemctl start anvilsrv@username
• Stop: sudo systemctl stop anvilsrv@username
• Restart: sudo systemctl restart anvilsrv@username
• Status: sudo systemctl status anvilsrv@username
• Logs: sudo journalctl -u anvilsrv@username -f
• Disable: sudo systemctl disable anvilsrv@username

3. anvilsrv.service - Simple System Service

Basic system service (less flexible than the template).

Installation:

# Edit the service file to set the correct username
nano services/systemd/anvilsrv.service

# Copy the service file
sudo cp services/systemd/anvilsrv.service /etc/systemd/system/

# Reload systemd daemon
sudo systemctl daemon-reload

# Enable and start the service
sudo systemctl enable anvilsrv.service
sudo systemctl start anvilsrv.service

# Check status
sudo systemctl status anvilsrv.service

Choosing the Right Service

• User Service (anvilsrv-user.service): Best for most users. Runs in your user session, easier to manage, no sudo required.
• System Service Template (anvilsrv@.service): Good for multi-user systems or when you need system-level control.
• Simple System Service (anvilsrv.service): Basic system service, less flexible.

Troubleshooting

Check Logs

# User service
journalctl --user -u anvilsrv-user -n 50

# System service
sudo journalctl -u anvilsrv@username -n 50

Verify Service is Running

# User service
systemctl --user status anvilsrv-user

# System service
sudo systemctl status anvilsrv@username

Check if anvilsrv is Actually Running

anvilsrv status

Restart After Code Changes

# User service
systemctl --user restart anvilsrv-user

# System service
sudo systemctl restart anvilsrv@username

Notes

• The service automatically restarts on failure with a 5-second delay
• PID file is cleaned up on service stop
• Logs are available via journalctl
• The service uses the anvilsrv binary from ~/bin/anvilsrv
