  3. Verify hash of donwnloaded file

    Get hash of downloaded file and compare it with official hashes
    sha256sum erigon_v2.60.10_linux_amd64v2.tar.gz
    And check it compare to the provided hash for the file from https://github.com/erigontech/erigon/releases/download/v2.60.10/erigon_v2.60.10_checksums.txt (Note: The link links at 2.60.10 version )
  4. Extract the downloaded package

    tar xvf erigon_v2.60.10_linux_amd64v2.tar.gz
  5. Copy extracted Erigon library

    sudo cp -a erigon_v2.60.10_linux_amd64v2 /usr/local/bin/erigonlib
  6. Remove downloaded files

    cd ~/downloads && rm -r erigon_v2.60.10_linux_amd64v2.tar.gz && rm -r erigon_v2.60.10_linux_amd64v2

Configurate the service

Create a system user and data directory for Erigon service

  • Create a user

    :
    sudo useradd --system --no-create-home --shell /bin/false erigon
  • Create a folder for Erigon data on network

    :
    sudo mkdir -p /var/lib/erigon
  • Set access permission and ownership for the Erigon data folder

    sudo chown -R erigon:erigon /var/lib/erigon

Configurate & Run Erigon Service

  • Choose ports for communication

    Change the default ports below if you are going to stake on more chains simultaneously (e.g. Ethereum and Gnosis at once) on the same machine. If you are going to stake only, you can keep the default ports. If you are changing the default ports, be sure that the newly selected port is not already in used. A port in used may be checked with following code:

    ss -tuln | grep ':PORT'
    • If it returns empty response, the port is free and can be used.

    Ports selection

    • (Default port: 30303)
    • (Default port: 8545)
    • (Default port: 8551)
  • Enable port for P2P communication (execution client)

    To allow execution client synchronization, there's need to enable P2P traffic to TCP (allows the node to connect to peers) and UDP (allows node discovery) port 30303. It may be done with following UFW setup:

    $ sudo ufw allow 30303
  • Create configuration file for Erigon service

    1. Open configuration file
      sudo nano /etc/systemd/system/erigon.service
    2. Copy the configuration below into the file
