Deployment on Ubuntu

This script can be used for download and deployment on Ubuntu 20.04 or 18.04

Download script, check https://geth.ethereum.org/downloads/

Modify geth_version, geth_commit, geth_hash. Unfortunatelly Geth developeres not provide the latest links, so you have to set all manually.

wget https://raw.githubusercontent.com/begetan/geth-ubuntu/master/geth-install.sh
chmod +x geth-install.sh
sudo ./geth-install.sh

Update

For updates, you may run the same script. It will check the existence of the Geth data directory and will not overwrite configs.

sudo systemctl stop geth.service
sudo ./geth-install.sh
sudo systemctl start geth.service
