How To Install Full Node Gravity Bridge Mainnet

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 GRAVITY_CHAIN_ID=gravity-bridge-3" >> $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="1.19.4"
  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
mkdir gravity-bin && cd gravity-bin
wget https://github.com/Gravity-Bridge/Gravity-Bridge/releases/download/v1.8.1/gravity-linux-amd64
mv gravity-linux-amd64 gravity
wget https://github.com/Gravity-Bridge/Gravity-Bridge/releases/download/v1.8.1/gbt
chmod +x *
sudo mv * /usr/bin/

Init app

gravity init $NODENAME --chain-id $GRAVITY_CHAIN_ID

Download configuration

wget https://raw.githubusercontent.com/Gravity-Bridge/gravity-docs/main/genesis.json
mv genesis.json $HOME/.gravity/config/genesis.json
wget -O "$HOME/addrbook.json" https://snapshots.polkachu.com/addrbook/gravity/addrbook.json
mv "$HOME/addrbook.json" ~/.gravity/config

Set seeds and peers

seeds="[email protected]:14256,[email protected]:10556"
peers="[email protected]:26856,[email protected]:26656,[email protected]:26656,[email protected]:42656"
sed -i -e 's|^seeds *=.*|seeds = "'$seeds'"|; s|^persistent_peers *=.*|persistent_peers = "'$peers'"|' $HOME/.gravity/config/config.toml

Disable indexing

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

Config pruning

sed -i 's|pruning = "default"|pruning = "custom"|g' $HOME/.gravity/config/app.toml
sed -i 's|pruning-keep-recent = "0"|pruning-keep-recent = "100"|g' $HOME/.gravity/config/app.toml
sed -i 's|pruning-interval = "0"|pruning-interval = "50"|g' $HOME/.gravity/config/app.toml

Set minimum gas price

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

Create service

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

[Service]
User=$USER
ExecStart=$(which gravity) start --home $HOME/.gravity
Restart=on-failure
RestartSec=3
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF

Register and start service

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