create service file and start node

Create service file Create a dhealth.service file in the /etc/systemd/system folder with the following code.

sudo tee /etc/systemd/system/dhealthd.service > /dev/null <<EOF
[Unit]
Description=dhealth
After=network-online.target

[Service]
User=$USER
ExecStart=$(which dhealthd) start
Restart=always
RestartSec=3
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF

Enable Service and Start Node

sudo systemctl daemon-reload
sudo systemctl enable dhealthd
sudo systemctl restart dhealthd
sudo journalctl -u dhealthd -f -o cat
