I chose the latest stable build of the exporter from https://prometheus.io/download/#node_exporter

You may need to update the .py file if a new version comes out or you want a different version.

useradd --no-create-home --shell /bin/false node_exporter

wget https://github.com/prometheus/node_exporter/releases/download/v0.16.0/node_exporter-0.16.0.linux-amd64.tar.gz

sha256sum node_exporter-0.16.0.linux-amd64.tar.gz

mkdir node_exporter_tmp

tar xvf node_exporter-0.16.0.linux-amd64.tar.gz

cp node_exporter-0.16.0.linux-amd64/node_exporter /usr/local/bin

chown node_exporter:node_exporter /usr/local/bin/node_exporter

rm -rf node_exporter-0.15.1.linux-amd64.tar.gz node_exporter-0.16.0.linux-amd64

vi /etc/systemd/system/node_exporter.service
