</strong>sudo chmod +x data-avail
</code></pre>

## Create a service&#x20;

```
yourname=<NodeName> 
```

Ex: <mark style="color:red;">**yourname=NodeSyncTop**</mark>

```
sudo tee /etc/systemd/system/availd.service > /dev/null << EOF
[Unit]
Description=Avail Validator
After=network.target
StartLimitIntervalSec=0
[Service]
User=$USER
Type=simple
Restart=always
RestartSec=120
ExecStart=${HOME}/avail-node/data-avail \
 -d ${HOME}/avail-node/data \
 --chain goldberg --port 30333 \
 --validator \
 --name $yourname

[Install]
WantedBy=multi-user.target

```

```
sudo systemctl daemon-reload
sudo systemctl enable availd
sudo systemctl restart availd && sudo journalctl -u availd -f -o cat
