How to Install Grafana in Ubuntu 18.04|20.04|22.04

Grafana is a tool for monitoring, analyzing, and visualizing of current system data. It generates graphs and dashboards from a time-series database (Graphite, InfluxDB, or OpenTSDB).

Grafana is a data visualization and monitoring tool that allows users to create and edit both log and data graphs and create metrics. Used in conjunction with time series databases such as InfluxDB, Prometheus, Elasticsearch, and Grafana can use plugins as templates and ready-made graphs and metrics.

Grafana provides the following opportunities:

Data Visualization: This allows for fast and flexible visualization with many options and settings.
Dynamic Dashboards: Provides the ability to create dynamic and reusable panels with templated variables.
Metrics Exploration: Explore your data with ad-hoc queries and dynamic drill-down by splitting the view and comparing different time ranges and sources.
Extensive Alert Capabilities: Visually define alert rules for your most important metrics. Grafana will continuously evaluate and send notifications to systems such as Slack, PagerDuty, VictorOps, and OpsGenie.
Mixed Data Sources: Mix different data sources on the same graph and for each query.
Data Logs: Provides tremendous opportunities to use data metrics in a log with labels and filters saved, which can be studied, viewed, and broadcasted.

In this lesson, we are going to learn how to install Grafana in Ubuntu 18, 20, or 22. Have your Ubuntu instance running with the user who has sudo rights. You can run one on Angani Cloud at an affordable price.

We then head off to install the essential packages (apt-transport-https and software-properties-common) for the correct running of Grafana:

As Grafana is not in the default repository package, we must add the GPG key to the trusted keys. This step verifies the download came from the expected source.

$ wget -q -O - https://packages.grafana.com/gpg.key | apt-key add -
OK

Now add the repository where we will install Grafana.

$ echo "deb https://packages.grafana.com/oss/deb stable main" | tee -a /etc/apt/sources.list.d/grafana.list
deb https://packages.grafana.com/oss/deb stable main

Now we update the cache repository. Once done we proceed to install Grafana using the APT command as below

sudo apt update
sudo apt install grafana

### NOT starting on installation, please execute the following statements to configure grafana
to start automatically using systemd
 sudo /bin/systemctl daemon-reload
sudo /bin/systemctl enable grafana-server
### You can start grafana-server by executing
 sudo /bin/systemctl start grafana-server
Processing triggers for systemd (245.4-4ubuntu3.17) ...
Processing triggers for man-db (2.9.1-1) ...

To check on the version installed run the below command

$ grafana-server -v 
Version 8.5.4 (commit: 78ee958143, branch: HEAD)

We enable Grafana-server to allow it to automatically start if the server reboots

$ sudo systemctl enable grafana-server

Synchronizing state of grafana-server.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable grafana-server
Created symlink /etc/systemd/system/multi-user.target.wants/grafana-server.service → /lib/systemd/system/grafana-server.service.

We then start the service for Grafana to work properly

$ sudo systemctl start grafana-server

Firewall Configuration

We will have to configure the firewall to allow port 3000 (for grafana) if the firewall on your server is active. Grafana runs on port 3000 by default. We’ll need to allow access to this port using the command below

$ sudo ufw allow 3000/tcp
Rules updated
Rules updated (v6)
$ sudo ufw reload
Firewall reloaded

Now that we are done with the installation of Grafana, we can access it. To do so, you need to open your browser and enter the IP or FQDN of your Grafana server:

http://server_IP:3000 or http://FQDN:3000

Open grafana in browser

The default username and password are admin. After that, you will be prompted to change the default password. This will let you access directly to your dashboard.

Grafana admin/user login page

You can now start working on your Grafana and set up everything. You can have a look at the official documentation if you need some guides for your configuration.
