Here I will show you how to install Grafana on a headless Debian server using the last current (at the time) stable release.
First, make sure your Debian server is up to date:
sudo apt-get update && apt-get upgrade
Download the Grafana stable release. I put theese packages in the /tmp folder:
cd /tmp/ sudo wget https://dl.grafana.com/oss/release/grafana_5.4.3_amd64.deb
Install adduser and libfontconfig:
sudo apt-get install -y adduser libfontconfig
Unpack grafana:
sudo dpkg -i grafana_5.4.3_amd64.deb
Start Grafana server:
systemctl unmask grafana-server.service systemctl start grafana-server
You should now reach your server on the standard webport for Grafana:
