{% hint style="info" %} *The Ethereum Sepolia archive node has a size of 1TB on November 15th, 2024* {% endhint %} ## Setup production Erigon {% hint style="success" %} This guide covers the installation of`Erigon`, an implementation of Ethereum (execution layer), on the efficiency frontier, **Archive Node** by default, and `Lighthouse`, as a Consensus Layer. {% endhint %} ## Pre-Requisites {% code overflow="wrap" %} ```bash sudo apt update -y && sudo apt upgrade -y && sudo apt autoremove -y sudo apt install -y libgtest-dev libomp-dev libgmp-dev git make wget aria2 gcc pkg-config libusb-1.0-0-dev libudev-dev jq g++ curl libssl-dev screen apache2-utils build-essential ``` {% endcode %} ### Setting up Firewall Set explicit default UFW rules ```bash sudo ufw default deny incoming sudo ufw default allow outgoing ``` Allow SSH and peers ```bash sudo ufw allow 22/tcp sudo ufw allow 30303 sudo ufw allow 9001 ``` Allow remote RPC connections with the Node ```bash sudo ufw allow from ${REMOTE.HOST.IP} to any port 8545 sudo ufw allow from ${REMOTE.HOST.IP} to any port 5052 ``` {% hint style="warning" %} Not advised to allow all or unknown IP address to RPC port {% endhint %} Enable Firewall 
sudo ufw enable
To check the status of UFW and see the current rules 
sudo ufw status verbose
### Install GO {% hint style="info" %} Go version 1.21+ is required {% endhint %} ```bash sudo wget https://go.dev/dl/go1.21.6.linux-amd64.tar.gz && sudo rm -rf /usr/local/go && sudo tar -C /usr/local -xzf go1.21.6.linux-amd64.tar.gz && rm go1.21.6.linux-amd64.tar.gz echo 'export PATH=$PATH:/usr/local/go/bin:/root/.local/bin' >> /root/.bashrc source /root/.bashrc #verify Go installation go version ``` ### Build Erigon RPC Node ```bash git clone --recurse-submodules https://github.com/ledgerwatch/erigon.git cd erigon git checkout v2.60.10 make erigon ``` #### Create Data directory and jwt secret file ```bash cd .. mkdir erigon-sepolia_data && cd erigon-sepolia_data sudo openssl rand -hex -out /root/erigon-sepolia_data/jwtsecret 32 ``` #### Create Systemd service for Erigon ```bash sudo nano /etc/systemd/system/erigon-sepolia.service ``` Paste the configs and save by entering `ctrl+X` and `Y+ENTER`: ```bash [Unit] Description=Erigon Sepolia Service After=network.target StartLimitIntervalSec=200 StartLimitBurst=5 [Service] Type=simple Restart=on-failure RestartSec=5 TimeoutSec=900 User=root Nice=0 LimitNOFILE=200000 WorkingDirectory=/root/erigon/build/bin/

--pprof.port=6070 [Install] WantedBy=multi-user.target ``` #### Launch Erigon ```bash sudo systemctl daemon-reload #refresh systemd configuration when changes made sudo systemctl enable erigon-sepolia.service #enable erigon-sepolia.service at system startup sudo systemctl start erigon-sepolia.service #start erigon-sepolia.service sudo nano /etc/systemd/system/erigon-sepolia.service #make changes in erigon-sepolia.service file ``` ### Build Lighthouse Go to the [Releases](https://github.com/sigp/lighthouse/releases) page and select the latest release: ```bash cd /root/ mkdir lighthouse-sepolia_data mkdir lighthouse-sepolia && cd lighthouse-sepolia wget https://github.com/sigp/lighthouse/releases/download/v5.3.0/lighthouse-v5.3.0-x86_64-unknown-linux-gnu.tar.gz tar -xzf lighthouse-v5.3.0-x86_64-unknown-linux-gnu.tar.gz #Extract the tar.gz archive chmod +x /root/lighthouse-sepolia/ #Grant execute permissions to the files in the directory ``` #### Create systemd file for Lighthouse ```bash sudo nano /etc/systemd/system/lighthouse-sepolia.service ``` Paste the configs and save by entering `ctrl+X` and `Y+ENTER`: ```bash [Unit] Description=Lighthouse-sepolia Beacon Node After=network.target [Service] User=root WorkingDirectory=/root/lighthouse-sepolia/ ExecStart=/root/lighthouse-sepolia/lighthouse beacon_node \ --network sepolia \ --datadir

--execution-jwt /root/erigon-sepolia_data/jwt.hex \ --disable-deposit-contract-sync \ --prune-blobs false Restart=on-failure LimitNOFILE=1000000 [Install] WantedBy=default.target ``` #### Launch Lighthouse ```bash sudo systemctl daemon-reload #refresh systemd configuration when changes made sudo systemctl enable lighthouse-sepolia.service #enable lighthouse-sepolia service at system startup sudo systemctl start lighthouse-sepolia.service #start lighthouse-sepolia sudo nano /etc/systemd/system/lighthouse-sepolia.service #make changes in lighthouse-sepolia.service file ``` ### Monitor the logs for errors ```bash journalctl -u erigon-sepolia.service -f -n 100 #follow logs of erigon-sepolia.service journalctl -u lighthouse-sepolia.service -f -n 100 #follow logs of lighthouse-sepolia.service ``` During the synchonization, you are expected to get following log messages from`erigon`: ```bash [INFO] [09-06|02:52:15.496] [4/12 Execution] Executed blocks
