create service file and start node

Create service file Create a wardend.service file in the /etc/systemd/system folder with the following code. You can change USER with your Linux user name. You need sudo previlege to do this step.

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

[Service]
User=$USER
ExecStart=$(which tacchaind) start
Restart=on-failure
RestartSec=3
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF

• Enable Service and Start Node

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