#### How To Install Full Node 0G Testnet

### Setting up vars

Your Nodename (validator) that will shows in explorer

```
NODENAME=<Your_Nodename_Moniker>
```

Save variables to system

```
echo "export NODENAME=$NODENAME" >> $HOME/.bash_profile
if [ ! $WALLET ]; then
	echo "export WALLET=wallet" >> $HOME/.bash_profile
fi
echo "export 0G_CHAIN_ID=zgtendermint_16600-1" >> $HOME/.bash_profile
source $HOME/.bash_profile
```

### Update packages

```
sudo apt update && sudo apt upgrade -y
```

### Install dependencies

```
sudo apt install curl build-essential git wget jq make gcc tmux net-tools ccze -y
```

### Install go

```
if ! [ -x "$(command -v go)" ]; then
  ver="1.20.2"
  cd $HOME
  wget "https://golang.org/dl/go$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"
  echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> ~/.bash_profile
  source ~/.bash_profile
fi
```

### Download and build binaries

```
cd $HOME
git clone -b v0.1.0 https://github.com/0glabs/0g-chain.git
./0g-chain/networks/testnet/install.sh
source ~/.profile
0gchaind version
```

### Config app

```
0gchaind config chain-id $0G_CHAIN_ID
```

### Init app

```
0gchaind init $NODENAME --chain-id $0G_CHAIN_ID
```

#### Download configuration

```
cd $HOME
curl -Ls https://snap1.konsortech.xyz/0gchain/genesis.json > $HOME/.0gchain/config/genesis.json
curl -Ls https://snap1.konsortech.xyz/0gchain/addrbook.json > $HOME/.0gchain/config/addrbook.json
```

### Disable indexing

```
indexer="null"
sed -i -e "s/^indexer *=.*/indexer = \"$indexer\"/" $HOME/.0gchain/config/config.toml
```

### Config pruning

```
sed -i 's|pruning = "default"|pruning = "custom"|g' $HOME/.0gchain/config/app.toml
sed -i 's|pruning-keep-recent = "0"|pruning-keep-recent = "100"|g' $HOME/.0gchain/config/app.toml
sed -i 's|pruning-interval = "0"|pruning-interval = "10"|g' $HOME/.0gchain/config/app.toml
```

### Set minimum gas price

```
sed -i 's|^minimum-gas-prices *=.*|minimum-gas-prices = "0ua0gi"|g' $HOME/.0gchain/config/app.toml
```

### Create service

```
sudo tee /etc/systemd/system/0gchaind.service > /dev/null << EOF
[Unit]
Description=0G Node
After=network-online.target
[Service]
User=$USER
ExecStart=$(which 0gchaind) start
Restart=on-failure
RestartSec=10
LimitNOFILE=10000
[Install]
WantedBy=multi-user.target
EOF
```

### Register and start service

```
sudo systemctl daemon-reload
sudo systemctl enable 0gchaind
sudo systemctl restart 0gchaind && sudo journalctl -u 0gchaind -f -o cat
```
