Install Celestia-node

cd $HOME
rm -rf celestia-node
git clone https://github.com/celestiaorg/celestia-node.git
cd celestia-node/
git checkout tags/v0.28.5-mocha  
make build 
sudo make install 
make cel-key

---

Create wallet

./cel-key add my_celes_key --keyring-backend test --node.type full --p2p.network mocha

(Optional) Restore an existing cel_key

cd ~/celestia-node
./cel-key add my_celes_key --keyring-backend test --node.type full --recover

You can find the address by running the following command in the celestia-node directory

cd $HOME/celestia-node
./cel-key list --node.type full --keyring-backend test --p2p.network mocha

---

Config and init app

celestia full init --core.ip <RPC_NODE_IP> --p2p.network mocha-4

If keys have not been created previously, Once you start the full Node, a wallet key will be generated for you. You will need to fund that address with Testnet tokens to pay for PayForBlob transactions. You can find the address by running the following command:

cd $HOME/celestia-node
./cel-key list --node.type full --keyring-backend test --p2p.network mocha

---

Create Service file

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

[Service]
User=$USER
ExecStart=$(which celestia) full start --archival \
--p2p.network mocha \
--metrics.tls=true --metrics --metrics.endpoint otel.mocha.celestia.observer
Restart=on-failure
RestartSec=3
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF

---

Enable and start service

sudo systemctl daemon-reload
sudo systemctl enable celestia-full
sudo systemctl restart celestia-full && sudo journalctl -u celestia-full -fo cat

---

Get your node's peerId information

NODE_TYPE=full
AUTH_TOKEN=$(celestia $NODE_TYPE auth admin --p2p.network mocha)

Then you can get the peerId of your node with the following curl command

curl -X POST \
     -H "Authorization: Bearer $AUTH_TOKEN" \
     -H 'Content-Type: application/json' \
     -d '{"jsonrpc":"2.0","id":0,"method":"p2p.Info","params":[]}' \
