Light Node Setup for Testnet — mocha-4
Official documentation
Setting up a light node
Update packages and Install dependencies:
sudo apt update && sudo apt upgrade -y
sudo apt install curl git wget htop tmux build-essential jq make gcc tar clang pkg-config libssl-dev ncdu -y
Install :
cd ~
! [ -x "$(command -v go)" ] && {
VER="1.23.1"
wget "https://golang.org/dl/go$VER.linux-amd64.tar.gz"
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf "go$VER.linux-amd64.tar.gz"
rm "go$VER.linux-amd64.tar.gz"
[ ! -f ~/.bash_profile ] && touch ~/.bash_profile
echo "export PATH=$PATH:/usr/local/go/bin:~/go/bin" >> ~/.bash_profile
source ~/.bash_profile
}
[ ! -d ~/go/bin ] && mkdir -p ~/go/bin
go version
Download and build binaries:
cd $HOME
rm -rf celestia-node
git clone https://github.com/celestiaorg/celestia-node.git
cd celestia-node/
git checkout tags/v0.20.3-mocha
make build
sudo make install
make cel-key
Config and init app:
celestia light init --core.ip <RPC_NODE_IP> --p2p.network mocha
Create wallet:
KEY_NAME="my_celes_key"
cd ~/celestia-node
./cel-key add $KEY_NAME --keyring-backend test --node.type light --p2p.network mocha
(Optional) Restore an existing cel_key:
KEY_NAME="my_celes_key"
cd ~/celestia-node
./cel-key add $KEY_NAME --keyring-backend test --node.type light --p2p.network mocha --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 light --keyring-backend test --p2p.network mocha
Create Service file and replace FULL node ip, RPC and gRPC ports:
sudo tee /etc/systemd/system/celestia-light.service > /dev/null <<EOF

Enable and start service:
sudo systemctl daemon-reload
sudo systemctl enable celestia-light
sudo systemctl restart celestia-light && sudo journalctl -u celestia-light -fo cat
Cheat sheet
Check light wallet balance:
celestia state balance --node.store ~/.celestia-light-mocha-4/
Get wallet address:
cd $HOME/celestia-node
./cel-key list --node.type light --keyring-backend test --p2p.network mocha
Restore an existing cel_key:
KEY_NAME="my_celes_key"
cd ~/celestia-node
./cel-key add $KEY_NAME --keyring-backend test --node.type light --recover --p2p.network mocha
Check light node status:
celestia header sync-state --node.store ~/.celestia-light-mocha-4/
Get Node ID:
celestia p2p info --node.store ~/.celestia-light-mocha-4/
(Optional) Add permissions for transferring keys to another server:
chmod -R 700 ~/.celestia-light-mocha-4
Reset node:
celestia light unsafe-reset-store --p2p.network mocha
Upgrade
Stop light node:
sudo systemctl stop celestia-light
Download binary:
cd $HOME
rm -rf celestia-node
git clone https://github.com/celestiaorg/celestia-node.git
cd celestia-node/
git checkout tags/v0.20.3-mocha
make build
sudo make install
make cel-key
Update:
celestia light config-update --p2p.network mocha
Start light node:
sudo systemctl restart celestia-light && sudo journalctl -u celestia-light -fo cat
Delete light node
sudo systemctl stop celestia-light
sudo systemctl disable celestia-light
sudo rm /etc/systemd/system/celestia-light*
rm -rf $HOME/celestia-node $HOME/.celestia-app $HOME/.celestia-light-mocha
