0g Node Installtion Guide

Update Dependencies:

sudo apt update
sudo apt install curl git jq build-essential gcc unzip wget lz4 -y

Install GO:

cd $HOME && \\
ver="1.21.3" && \\
wget "<https://golang.org/dl/go$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" >> $HOME/.bash_profile && \\
source $HOME/.bash_profile && \\
go version

Install binary:

git clone -b v0.1.0 <https://github.com/0glabs/0g-chain.git>
./0g-chain/networks/testnet/install.sh
source .profile

Set variables:

You can personalize them

echo 'export MONIKER="type_your_moniker_nodebrand"' >> ~/.bash_profile
echo 'export CHAIN_ID="zgtendermint_16600-1"' >> ~/.bash_profile
echo 'export WALLET_NAME="wallet"' >> ~/.bash_profile
echo 'export RPC_PORT="26657"' >> ~/.bash_profile
source $HOME/.bash_profile

Initialize the node:

cd $HOME
0gchaind config chain-id $CHAIN_ID
0gchaind init $MONIKER --chain-id $CHAIN_ID
0gchaind config node tcp://localhost:$RPC_PORT
0gchaind config keyring-backend os

Install current release:

wget -P ~/.0gchain/config <https://github.com/0glabs/0g-chain/releases/download/v0.1.0/genesis.json>

Configure config.toml file:

PEERS="" && \\
SEEDS="c4d619f6088cb0b24b4ab43a0510bf9251ab5d7f@54.241.167.190:26656,44d11d4ba92a01b520923f51632d2450984d5886@54.176.175.48:26656,f2693dd86766b5bf8fd6ab87e2e970d564d20aff@54.193.250.204:26656,f878d40c538c8c23653a5b70f615f8dccec6fb9f@54.215.187.94:26656" && \\
sed -i -e "s/^seeds *=.*/seeds = \\"$SEEDS\\"/; s/^persistent_peers *=.*/persistent_peers = \\"$PEERS\\"/" $HOME/.0gchain/config/config.toml

Set the config:

EXTERNAL_IP=$(wget -qO- eth0.me) \\
PROXY_APP_PORT=26658 \\
P2P_PORT=26656 \\
PPROF_PORT=6060 \\
API_PORT=1317 \\
GRPC_PORT=9090 \\
GRPC_WEB_PORT=9091

Set the port and address:

sed -i \\
    -e "s/\\(proxy_app = \\"tcp:\\/\\/\\)\\([^:]*\\):\\([0-9]*\\).*/\\1\\2:$PROXY_APP_PORT\\"/" \\
    -e "s/\\(laddr = \\"tcp:\\/\\/\\)\\([^:]*\\):\\([0-9]*\\).*/\\1\\2:$RPC_PORT\\"/" \\

    $HOME/.0gchain/config/config.toml

sed -i \\

Set the pruning:

sed -i.bak -e "s/^pruning *=.*/pruning = \\"custom\\"/" $HOME/.0gchain/config/app.toml
sed -i.bak -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \\"100\\"/" $HOME/.0gchain/config/app.toml
sed -i.bak -e "s/^pruning-interval *=.*/pruning-interval = \\"10\\"/" $HOME/.0gchain/config/app.toml

Set the gas price:

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

Set indexer:

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

Create a service file:

sudo tee /etc/systemd/system/ogd.service > /dev/null <<EOF
[Unit]

[Service]
User=$USER

ExecStart=$(which 0gchaind) start --home $HOME/.0gchain

Install addrbook:

curl -Ls <https://snapshots.dimmer.sbs/snapshots/testnet/zero-gravity/addrbook.json> > $HOME/.0gchain/config/addrbook.json

Install Spanshot:

sudo systemctl stop ogd
cp $HOME/.0gchain/data/priv_validator_state.json $HOME/.0gchain/priv_validator_state.json.backup
rm -rf $HOME/.0gchain/data
curl -L <http://snapshots.dimmer.sbs/snapshots/testnet/zero-gravity/zgtendermint_16600-1_latest.tar.lz4> | tar -Ilz4 -xf - -C $HOME/.0gchain
mv $HOME/.0gchain/priv_validator_state.json.backup $HOME/.0gchain/data/priv_validator_state.json
sudo systemctl restart ogd && sudo journalctl -u ogd -f -o cat

Update peers

PEERS=$(curl -s --max-time 3 --retry 2 --retry-connrefused "<https://snapshots.dimmer.sbs/snapshots/testnet/zero-gravity/peers.txt>")
if [ -z "$PEERS" ]; then
    echo "No peers were retrieved from the URL."
else
    echo -e "\\nPEERS: "$PEERS""
    sed -i "s/^persistent_peers *=.*/persistent_peers = "$PEERS"/" "$HOME/.0gchain/config/config.toml"
    echo -e "\\nConfiguration file updated successfully.\\n"
fi

Start node:

sudo systemctl daemon-reload && \\\\
sudo systemctl enable ogd && \\\\
sudo systemctl restart ogd && sudo journalctl -u ogd -f -o cat

Check node synchronization:

If you get false, you can install the validator. If it is true, you have to wait.
