How to Install Grafana on a Raspberry Pi

What is Grafana? Grafana is the software that is used to graph and make pretty pictures out of all the data collected by Prometheus. It’s relatively straightforward to install and there’s an ARM version already built and ready for download on their website!

First, do your usual updates:

apt update
apt upgrade

Let’s install the APT key and the repo. The APT key is used to verify the packages actually came from the Grafana server and have been signed as such. To add the Grafana APT key to your Raspberry Pi’s keychain, run the following command:

wget -q -O - | sudo apt-key add -

The Raspberry will reply with a simple: OK

Now add the repo with this one-liner:

echo "deb stable main" | sudo tee -a /etc/apt/sources.list.d/grafana.list

The Raspberry echos the line that it just added to the sources directory. Having added a new repo, you’ll need to run update again:

apt update

Now, we can install Grafana, enable it, and run it (as root):

apt install grafana
systemctl daemon-reload
systemctl enable grafana-server
systemctl start grafana-server

We have Grafana installed (and running)! I installed it on my prometheus server, your hostname may vary. Go to this URL:


and you’ll get the Grafana login page:

The default login is admin/admin Once you’ve authenticated, you’ll be presented with a nice collection of tutorials. You can click on the leftmost one and work your way through them. I won’t try to replicate it here. Clicking that box will open a new browser tab to Hey, and guess what! I’ve given you a head start. Skip all the docker stuff and click on Step 4, where you’ve already installed it and logged in! Note, the tutorial thinks you’re running in docker on your localhost, so you’ll have to type in the name of your prometheus raspberry. Have fun!
