Installing Erigon client

Erigon documentation: https://erigon.gitbook.io/erigon

1. Find the latest stable version of Erigon on Github

   • Find latest Erigon version at https://github.com/ledgerwatch/erigon/releases. AMD64 v1/v2 links at Microarchitecture levels.
   • Write latest stable Erigon version:

2. Download Erigon version 2.61.0

   cd ~/downloads && curl -LO https://github.com/erigontech/erigon/releases/download/v2.61.0/erigon_v2.61.0_linux_amd64v2.tar.gz

3. Verify hash of donwnloaded file

   Get hash of downloaded file and compare it with official hashes

   sha256sum erigon_v2.61.0_linux_amd64v2.tar.gz

   And check it compare to the provided hash for the file from https://github.com/erigontech/erigon/releases/download/v2.61.0/erigon_v2.61.0_checksums.txt (Note: The link links at 2.61.0 version )

4. Extract the downloaded package

   tar xvf erigon_v2.61.0_linux_amd64v2.tar.gz

5. Copy extracted Erigon library

   sudo cp -a erigon_v2.61.0_linux_amd64v2 /usr/local/bin/erigonlib

6. Remove downloaded files

   cd ~/downloads && rm -r erigon_v2.61.0_linux_amd64v2.tar.gz && rm -r erigon_v2.61.0_linux_amd64v2

Configurate service

Create a system user and data directory for Erigon service

• Create a user

  Service/User name:

  sudo useradd --system --no-create-home --shell /bin/false erigon

• Create a folder for Erigon data on network

  Service data directory:

  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

  • P2P network (TCP, UDP): (Default port: 30303)
  • JSON-RPC interface (TCP): (Default port: 8545)
  • Execution endpoint (TCP): (Default port: 8551)

• Enable ports communication

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

  $ sudo ufw allow 30303

  Use this option only if you need operate execution client and beacon client on different machines.

  • Enable port 30303 for P2P traffic

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

    $ sudo ufw allow 30303

  • Enable port 8551 for IP of your second machine

    sudo ufw allow from 192.168.88.0/27 to any port 8551

    Note: Be sure you use proper IP of your second machine / proper local network configuration.

• 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

     [Unit]
     Description=Erigon Execution Client (Ethereum Mainnet)
     After=network.target
     Wants=network.target
     [Service]
     User=eth-erigon
     Group=eth-erigon
     Type=simple
     Restart=always
     RestartSec=5

     #  --externalcl \
       --prune=htcr
     #  --private.api.addr= \
     #  --prune.r.before=11052984 
     [Install]
     WantedBy=default.target

     [Unit]

     #  --prune.r.before=11052984 
     [Install]
     WantedBy=default.target

     *Note: Update JsonRpc.JwtSecretFile, if you use different
  3. Press CTRL + X then Y then ENTER to save and exit the config file.

• Start the service

  sudo systemctl daemon-reload
  sudo systemctl start erigon

• Check the service

  systemctl status erigon
  journalctl -fu erigon

• Start the service on system startup

  sudo systemctl enable erigon

  • Open Delayed Start shell

    sudo nano /usr/local/bin/delayed-start.sh

    Configurate service start inside it

    systemctl start erigon.service

  • Be sure, delayed-start.service service controlling delayed-start.sh is enabled for auto start with system startup

    sudo systemctl enable delayed-start.service

  1. Configurate Staking Manager util

     • Open the configuration file

       sudo nano /usr/local/etc/staking/config/clients.conf

       If the file is empty, generate it with command sudo /usr/local/bin/staking.sh init

     • Set link to proper services. It should be as follow:

       executionClients="erigon"

       executionServices="erigon.service"

  2. Activate service to start automatically on OS startup

     • Open Start with delay util

       sudo nano /usr/local/bin/delayed-start.sh

     • Place or uncomment a command to start the Beacon client(s)

       /usr/local/bin/staking.sh start execution

     • Verify, that a service `delayed-start.service` exists and is automatically launched on system start.

       sudo systemctl enable delayed-start.service
