Geth + Teku

Precise commands to set up Geth + Teku on a clean Ubuntu Linux install:

ARM

For running on arm chips, simply replace amd64 with arm64 in all commands :)

Install pre-requisites

sudo apt install -y git gcc make default-jre

wget https://go.dev/dl/go1.17.3.linux-amd64.tar.gz
sudo rm -rf /usr/local/go && sudo tar -C /usr/local -xzf go1.17.3.linux-amd64.tar.gz
export PATH=$PATH:/usr/local/go/bin
go version

Clone the devnet config

cd ~
git clone https://github.com/eth2-clients/merge-testnets.git
cd ~/merge-testnets/merge-devnet-3

Build geth

git clone -b fix-optimistic-sync https://github.com/MariusVanDerWijden/go-ethereum.git
cd go-ethereum 
make geth
cd ..

git clone https://github.com/ConsenSys/teku.git
cd teku
./gradlew installDist
cd ..
