  1. Standalone Server Linux
  2. Grafana on docker env.

Standalone Server:-

OS version: Ubuntu 16.04
Grafana version: 5.4.2
Virtual Machine name: AWS/GCP/Azure

APT Repository

Create a file /etc/apt/sources.list.d/grafana.list and add the following to it.

deb stable main

Use the above line even if you are on Ubuntu or another Debian version. Then add our gpg key. This allows you to install signed packages.

curl | sudo apt-key add –

Update your Apt repositories and install Grafana

sudo apt-get update
sudo apt-get install Grafana

Start the server (via systemd)
To start the service using systemd:

systemctl daemon-reload
systemctl start grafana-server
systemctl status grafana-server

Enable the systemd service so that Grafana starts at boot.
sudo systemctl enable grafana-server.service

After installation to know the status of grafan server we must run

Sudo Systemctl status grafana-server and press enter and it will show the status of Grafana server.
