Install GO Copy

install the latest GO
=====================

    # install the latest GO
    cd $HOME && \
    ver="1.22.4" && \
    wget "https://golang.org/dl/go$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
    

### Build 0gchaind binary from source

    git clone -b v0.2.3 https://github.com/0glabs/0g-chain.git cd 0g-chain make install echo 'export PATH=$PATH:$(go env GOPATH)/bin' >> ~/.profile source ~/.profile 0gchaind version
    

### Setup your variable settings

    echo 'export MONIKER="your_node_name_here"' >> ~/.bash_profile echo 'export CHAIN_ID="zgtendermint_16600-2"' >> ~/.bash_profile echo 'export WALLET_NAME="wallet"' >> ~/.bash_profile echo 'export RPC_PORT="26657"' >> ~/.bash_profile source $HOME/.bash_profile
    

### 💻 Initialize node & create home directory for .0gchain

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

### Download genesis file

    rm ~/.0gchain/config/genesis.json wget -P ~/.0gchain/config https://github.com/0glabs/0g-chain/releases/download/v0.2.3/genesis.json
    

### Set 0G chain seeds

    SEEDS="81987895a11f6689ada254c6b57932ab7ed909b6@54.241.167.190:26656,010fb4de28667725a4fef26cdc7f9452cc34b16d@54.176.175.48:26656,e9b4bc203197b62cc7e6a80a64742e752f4210d5@54.193.250.204:26656,68b9145889e7576b652ca68d985826abd46ad660@18.166.164.232:26656" sed -i -e "s/^seeds =./seeds = "$SEEDS"/" $HOME/.0gchain/config/config.toml
    

### Set NodeCattel's Peers for faster peers discovery

    PEERS="6122859577a3465ba67065f3b63194cae67ef4c4@110.171.123.186:36656" sed -i "s/^persistent_peers =./persistent_peers = "$PEERS"/" "$HOME/.0gchain/config/config.toml"
    

### Confirm your ports - These can be changed if you are running more than one cosmos based chains

    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 all variables in config.toml & app.toml

    Set PROXY_APP, RPC, PPROF, P2P ports to config.toml
    sed -i -e "s/(proxy_app = "tcp://)([^:]):([0-9])./\1\2:$PROXY_APP_PORT"/" -e "s/(laddr = "tcp://)([^:]):([0-9])./\1\2:$RPC_PORT"/" -e "s/(pprof_laddr = ")([^:]):([0-9])./\1localhost:$PPROF_PORT"/" -e "/[p2p]/,/^[/{s/(laddr = "tcp://)([^:]):([0-9])./\1\2:$P2P_PORT"/}" -e "/[p2p]/,/^[/{s/(external_address = ")([^:]):([0-9])./\1${EXTERNAL_IP}:$P2P_PORT"/; t; s/(external_address = ")./\1${EXTERNAL_IP}:$P2P_PORT"/}" $HOME/.0gchain/config/config.toml
    

    Set TCP, GRPC, GRPC Web ports to app.toml
    sed -i -e "/[api]/,/^[/{s/(address = "tcp://)([^:]):([0-9])(".)/\1\2:$API_PORT\4/}" -e "/[grpc]/,/^[/{s/(address = ")([^:]):([0-9])(".)/\1\2:$GRPC_PORT\4/}" -e "/[grpc-web]/,/^[/{s/(address = ")([^:]):([0-9])(".*)/\1\2:$GRPC_WEB_PORT\4/}" $HOME/.0gchain/config/app.toml
    

    # Optional pruning setting - set it if you want to save storage space
    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 gas price to app.toml
    sed -i "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0ua0gi\"/" $HOME/.0gchain/config/app.toml
    

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

    # Set json-rpc to app.toml
    sed -i \
        -e 's/address = "127.0.0.1:8545"/address = "0.0.0.0:8545"/' \
        -e 's|^api = ".*"|api = "eth,txpool,personal,net,debug,web3"|' \
        $HOME/.0gchain/config/app.toml
    

### Create 0gd service for your node to run in the background

    sudo tee /etc/systemd/system/0gd.service > /dev/null <<EOF
    [Unit]
    Description=OG Node
    After=network.target
    
    [Service]
    User=$USER
    Type=simple
    ExecStart=$(which 0gchaind) start --json-rpc.api eth,txpool,personal,net,debug,web3 --home $HOME/.0gchain
    Restart=on-failure
    RestartSec=10
    LimitNOFILE=65535
    Environment="G0GC=900"
    Environment="G0MELIMIT=40GB"
    
    [Install]
    WantedBy=multi-user.target
    EOF
    

### Download snapshot for quick sync - powered by NodeCattel

    # download snapshot
    sudo systemctl stop 0gd
    cp $HOME/.0gchain/data/priv_validator_state.json $HOME/.0gchain/priv_validator_state.json.backup
    0gchaind tendermint unsafe-reset-all --home $HOME/.0gchain --keep-addr-book
    curl -L https://snapshot.nodecattel.xyz/0gchain/zgtendermint_16600-2_latest.tar.lz4 | sudo lz4 -dc - | sudo tar -xf - -C $HOME/.0gchain
    mv $HOME/.0gchain/priv_validator_state.json.backup $HOME/.0gchain/data/priv_validator_state.json
    

### 💻 Start node

    sudo systemctl daemon-reload && \
    sudo systemctl enable 0gd && \
    sudo systemctl restart 0gd && \
    sudo journalctl -u 0gd -f -o cat
