Deploying with systemd

Run FGP daemons as systemd services on Linux.

Create Service File

Create /etc/systemd/system/fgp-browser.service:

[Unit]
Description=FGP Browser Daemon
After=network.target

[Service]
Type=simple
User=your-username
ExecStart=/home/your-username/.cargo/bin/browser-gateway start
Restart=on-failure
RestartSec=5
Environment=RUST_LOG=info
Environment=CHROME_PATH=/usr/bin/google-chrome

[Install]
WantedBy=multi-user.target

Enable and Start

# Reload systemd
sudo systemctl daemon-reload

# Enable on boot
sudo systemctl enable fgp-browser

# Start now
sudo systemctl start fgp-browser

# Check status
sudo systemctl status fgp-browser

View Logs

# Recent logs
journalctl -u fgp-browser -f

# All logs
journalctl -u fgp-browser --no-pager

Multiple Daemons

Create a service file for each daemon:

/etc/systemd/system/fgp-browser.service
/etc/systemd/system/fgp-gmail.service
/etc/systemd/system/fgp-calendar.service

Or use a template:

# /etc/systemd/system/fgp@.service
[Unit]
Description=FGP %i Daemon

[Service]
Type=simple
User=your-username
ExecStart=/home/your-username/.fgp/services/%i/%i-daemon start
Restart=on-failure

[Install]
WantedBy=multi-user.target

Then:

sudo systemctl enable fgp@browser
sudo systemctl start fgp@browser

Socket Permissions

Ensure the socket directory is accessible:

chmod 700 ~/.fgp/services/browser/

Troubleshooting

Daemon Won't Start

Check logs:

journalctl -u fgp-browser -n 50

Permission Denied

Ensure user has access to Chrome and socket directories.

Chrome Not Found

Set CHROME_PATH in the service file's Environment directive.
