To store config and notes about how to build and operate an ETH 2.0 Beacon and Validator node

Running Beacon and Validator (Single Server)

Get a server

Best is to do it on your localhost.

• then you'll need to be logged in as a user called ubuntu with sudo privileges, or edit the files

Exoscale Medium (512Mb, 1 x 2198 MHz, 10 GB)

Also maybe try Digital Ocean

Network Settings

Open the following ports in the firewall to allow INGRESS tcp connections:

• 22 - to allow ssh connections
• 13000 - to allow improved p2p connectivity
• 3000 - to allow remote access to Grafana
• 4000 - to allow remote access to the Beacon Node

Very Quick Start

sudo apt -y install wget git tar g++

wget https://dl.google.com/go/go1.14.4.linux-amd64.tar.gz
sudo tar -C /usr/local -xzf go1.14.4.linux-amd64.tar.gz
git clone https://github.com/prysmaticlabs/prysm.git
cd prysm/beacon-chain
/usr/local/go/bin/go run main.go

Tested on clean @Exoscale Ubuntu 20.04 LTS image with 2GB RAM (no swap), 2 x 2198 MHz CPU

Quick Start

sudo apt update
sudo apt -y upgrade
sudo apt -y install build-essential

wget https://dl.google.com/go/go1.14.4.linux-amd64.tar.gz
sudo tar -C /usr/local -xzf go1.14.4.linux-amd64.tar.gz
export PATH=$PATH:/usr/local/go/bin
git clone https://github.com/prysmaticlabs/prysm.git
cd prysm/beacon-chain
go build
./beacon-chain

Installation Commands

sudo fallocate -l 2G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
sudo nano /etc/fstab

Add this to /etc/fstab

/swapfile swap swap defaults 0 0

then continue

sudo apt update -y && sudo apt upgrade -y
wget https://dl.google.com/go/go1.14.4.linux-amd64.tar.gz
tar -C /usr/local -xzf go1.14.4.linux-amd64.tar.gz
rm go1.14.4.linux-amd64.tar.gz
export PATH=$PATH:/usr/local/go/bin
sudo nano ~/.profile

Add this to .profile

export PATH=$PATH:/usr/local/go/bin

and then continue:

• log in to http://{ip-address}:3000/login admin/admin (first time load will be slow)
  • add a Prometheus data source with URL http://localhost:9090 and click "Save & Test" to see "Data source is working"
  • import new dashboard from here: https://github.com/GuillaumeMiralles/prysm-grafana-dashboard#creatingimporting-dashboards

Notes

• TO DO: Telegram Bot Alerting stuff

• Tail logs with

sudo journalctl -f --unit=beacon.service
sudo journalctl -f --unit=validator.service
sudo journalctl -f --unit=slasher.service
sudo journalctl -f --unit=prometheus.service
sudo journalctl -f --unit=grafana.service

• Wait for beacon node to sync

• Apply / Generate Keys

  • Note, in absence of a key, the process above will generate a key - delete this.
