systemd to auto start GRIN++ node.

I did write a small systemd service to auto start the GRIN++ node.

grinPP.service

[Unit]
Description=Grin node++
After=network.target

[Service]
WorkingDirectory=/opt/grin/grinPP
User=grin
Group=grin
PrivateDevices=yes
Type=simple
ExecReload="/bin/kill -HUP $MAINPID"
KillMode=mixed
KillSignal=SIGTERM
TimeoutStopSec=60
ExecStart=/opt/grin/grinPP/grin --headless > /dev/null 2>&1 &
Restart=on-failure
RestartSec=30

[Install]
WantedBy=multi-user.target
Alias=grinPP.service

adjust your WorkingDirectory and ExecStart paramentes as well as the User !

Place this file under /etc/system/system as grinPP.service.

You can now start the service using:

  • systemctl start grinPP.service

You can now stop the service using:

  • systemctl stop grinPP.service

You can now check status of this service using:

  • systemctl status grinPP.service
