# 0G Storage Node Setup Guide By [@beliamyr0](https://paragraph.com/@beliamyr0) · 2024-08-14 --- System Requirements ------------------- * **CPU:** 4 cores * **Memory:** 16GB * **Storage:** 500GB / 1TB NVMe SSD * **Bandwidth:** 500 Mbps for Download/Upload Update VPS & Install Required Packages -------------------------------------- sudo apt update && sudo apt upgrade -y sudo apt install curl git jq build-essential gcc unzip wget lz4 -y Install 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" >> ~/.bash_profile && \ source ~/.bash_profile && \ go version Install rustup -------------- To install Rustup, when prompted with options 1, 2, or 3, simply press Enter to select the default option and wait for the installation to complete. curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh Clone the Repository -------------------- git clone -b v0.3.1 https://github.com/0glabs/0g-storage-node.git Build Storage Node ------------------ In this step, you need to wait for the installation to complete. cd $HOME/0g-storage-node git submodule update --init sudo apt install cargo cargo build --release Create and Use Your Own RPC --------------------------- Open your app.toml file: nano $HOME/.0gchain/config/app.toml Update JSON-RPC settings: * Change 127.0.0.1:8545 to 0.0.0.0:8545. * Change api = "eth,net,web3" to api = "eth,txpool,personal,net,debug,web3" Save and exit. Open port `8545` sudo ufw allow 8545/tcp Note: Opening port 8545 can introduce security risks, so avoid publicizing your IP address. Retrieve Your RPC URL: To use your RPC for the storage node in the next step, your RPC URL will look like this: http://x.x.x.x:8545 Note: `x.x.x.x` is the IP address of this VPS. Setup Variables --------------- Replace `http://x.x.x.x:8545` with the RPC endpoint you created in the previous step. ENR_ADDRESS=$(wget -qO- eth0.me) echo "export ENR_ADDRESS=${ENR_ADDRESS}" >> ~/.bash_profile echo 'export LOG_CONTRACT_ADDRESS="0xb8F03061969da6Ad38f0a4a9f8a86bE71dA3c8E7"' >> ~/.bash_profile echo 'export MINE_CONTRACT="0x96D90AAcb2D5Ab5C69c1c351B0a0F105aae490bE"' >> ~/.bash_profile echo 'export ZGS_LOG_SYNC_BLOCK="334797"' >> ~/.bash_profile echo 'export BLOCKCHAIN_RPC_ENDPOINT="http://x.x.x.x:8545"' >> ~/.bash_profile source ~/.bash_profile echo -e "\n\033[31mCHECK YOUR VARIABLES\033[0m\n\nENR_ADDRESS: $ENR_ADDRESS\n\n\nLOG_CONTRACT_ADDRESS: $LOG_CONTRACT_ADDRESS\nMINE_CONTRACT: $MINE_CONTRACT\nZGS_LOG_SYNC_BLOCK: $ZGS_LOG_SYNC_BLOCK\nBLOCKCHAIN_RPC_ENDPOINT: $BLOCKCHAIN_RPC_ENDPOINT\n\n\033[33mwith love.\033[0m" Extract and Store Private Key ----------------------------- In this step, you will extract the private key from your Validator wallet and add it to the $HOME/0g-storage-node/run/config.toml file. PRIVATE_KEY=$(0gchaind keys unsafe-export-eth-key $WALLET_NAME) sed -i 's|^miner_key = ""|miner_key = "'"$PRIVATE_KEY"'"|' $HOME/0g-storage-node/run/config.toml **NOTE:** When running a validator node, ensure you create the wallet with the — eth option to be able to export the private key. Example: 0gchaind keys add $WALLET_NAME --eth Check your configuration ensure your settings are correct: echo $BLOCKCHAIN_RPC_ENDPOINT echo $LOG_CONTRACT_ADDRESS echo $PRIVATE_KEY Update your config.toml ----------------------- sed -i ' s|^\s*#\?\s*network_dir\s*=.*|network_dir = "network"| s|^\s*#\?\s*network_enr_address\s*=.*|network_enr_address = "'"$ENR_ADDRESS"'"| s|^\s*#\?\s*network_enr_tcp_port\s*=.*|network_enr_tcp_port = 1234| s|^\s*#\?\s*network_enr_udp_port\s*=.*|network_enr_udp_port = 1234| s|^\s*#\?\s*network_libp2p_port\s*=.*|network_libp2p_port = 1234| s|^\s*#\?\s*network_discovery_port\s*=.*|network_discovery_port = 1234| s|^\s*#\?\s*rpc_enabled\s*=.*|rpc_enabled = true| s|^\s*#\?\s*db_dir\s*=.*|db_dir = "db"| s|^\s*#\?\s*log_config_file\s*=.*|log_config_file = "log_config"| s|^\s*#\?\s*log_directory\s*=.*|log_directory = "log"| s|^\s*#\?\s*network_boot_nodes\s*=.*|network_boot_nodes = \["/ip4/54.219.26.22/udp/1234/p2p/16Uiu2HAmTVDGNhkHD98zDnJxQWu3i1FL1aFYeh9wiQTNu4pDCgps","/ip4/52.52.127.117/udp/1234/p2p/16Uiu2HAkzRjxK2gorngB1Xq84qDrT4hSVznYDHj6BkbaE4SGx9oS"\]| s|^\s*#\?\s*log_contract_address\s*=.*|log_contract_address = "'"$LOG_CONTRACT_ADDRESS"'"| s|^\s*#\?\s*mine_contract_address\s*=.*|mine_contract_address = "'"$MINE_CONTRACT"'"| s|^\s*#\?\s*log_sync_start_block_number\s*=.*|log_sync_start_block_number = '"$ZGS_LOG_SYNC_BLOCK"'| s|^\s*#\?\s*blockchain_rpc_endpoint\s*=.*|blockchain_rpc_endpoint = "'"$BLOCKCHAIN_RPC_ENDPOINT"'"| s|^\s*miner_id\s*=\s*""|# miner_id = ""| ' $HOME/0g-storage-node/run/config.toml Create Service File ------------------- sudo tee /etc/systemd/system/zgs.service > /dev/null <
