How To Install Grafana on Ubuntu 22.04 LTS

Hey there data enthusiasts! Ever find yourself drowning in a sea of numbers and logs, desperately trying to make sense of it all? Enter Grafana, the superhero of data visualization!

In a world where information overload is the norm, Grafana swoops in to save the day. It’s not just a tool; it’s your trusty sidekick in the quest for understanding your metrics, logs, and traces. From tech geeks to data dabblers, Grafana’s got something for everyone.

After installing Prometheus, we will install Grafana to visualize data from Prometheus (and many other Data Sources).

What You’ll Learn

By the end of this guide, you’ll have:

• A fully functional Grafana installation on Ubuntu 22.04 LTS
• Understanding of both OSS and Enterprise editions
• Knowledge of basic security configurations
• Next steps for connecting data sources

Prerequisites

Understanding Grafana Editions

Before installation, it’s important to understand the two available editions:

Grafana OSS (Open Source Software)

• Free and open-source
• Core visualization features
• Community support
• Perfect for small to medium deployments

Grafana Enterprise

• Commercial license required
• Advanced authentication (SAML, OAuth)
• Enhanced security features
• Priority support from Grafana Labs
• Advanced data source plugins

For this tutorial, we’ll show how to install both editions.

Prepare Your System

First, let’s ensure your Ubuntu system is up to date and install the necessary prerequisites:

# Update system packages
sudo apt update && sudo apt upgrade -y

# Install prerequisite packages
sudo apt-get install -y apt-transport-https software-properties-common wget curl gnupg2

What these packages do:

• apt-transport-https: Enables APT to retrieve packages over HTTPS
• software-properties-common: Provides tools for managing software repositories
• wget & curl: Download tools for fetching keys and packages
• gnupg2: Handles GPG key verification

Add Grafana Repository

Import the GPG key

First, create a directory for the GPG key and import Grafana’s signing key:

# Create directory for GPG keys
sudo mkdir -p /etc/apt/keyrings/

# Download and import Grafana's GPG key
wget -q -O - https://apt.grafana.com/gpg.key | gpg --dearmor | sudo tee /etc/apt/keyrings/grafana.gpg > /dev/null

Add the Repository

Add Grafana’s official repository to your system:

# Add Grafana repository for stable releases
echo "deb [signed-by=/etc/apt/keyrings/grafana.gpg] https://apt.grafana.com stable main" | sudo tee -a /etc/apt/sources.list.d/grafana.list

Update Package Lists

# Update package lists to include Grafana packages
sudo apt-get update

Install Grafana

Option A: Install Grafana OSS (Recommended for beginners)

sudo apt-get install grafana

Option B: Install Grafana Enterprise

sudo apt-get install grafana-enterprise

Note: Both installations use the same configuration files and follow the same setup process.

Configure and Start Grafana

Start the Grafana Service

# Reload systemd daemon
sudo systemctl daemon-reload

# Start Grafana server
sudo systemctl start grafana-server

# Check service status
sudo systemctl status grafana-server

You should see output similar to:

● grafana-server.service - Grafana instance
     Loaded: loaded (/lib/systemd/system/grafana-server.service; disabled; vendor preset: enabled)
     Active: active (running) since [timestamp]

Enable Auto-Start on Boot

# Enable Grafana to start automatically on system boot
sudo systemctl enable grafana-server

Verify Installation

# Check if Grafana is listening on port 3000
sudo netstat -tlnp | grep :3000

Access Grafana Web Interface

Initial Access

• Open your web browser
• Navigate to: http://YOUR_SERVER_IP:3000
• You should see the Grafana login page

Default Credentials

3. Choose a strong password following these guidelines:
   • At least 12 characters long
   • Mix of uppercase, lowercase, numbers, and symbols
   • Avoid common words or personal information

Verify Installation

Check Service Logs

# View Grafana logs
sudo journalctl -u grafana-server -f

Test Web Interface

1. Navigate to your Grafana instance
2. Log in with your new credentials
3. You should see the Grafana home dashboard

Troubleshooting

Common Issues and Solutions

Grafana Won’t Start

# Check for port conflicts
sudo lsof -i :3000

# Check system logs
sudo journalctl -u grafana-server --no-pager

Can’t Access Web Interface

• Verify firewall settings
• Check if Grafana is binding to the correct interface
• Ensure port 3000 isn’t blocked

Permission Issues

# Fix Grafana file permissions
sudo chown -R grafana:grafana /var/lib/grafana
sudo chown -R grafana:grafana /var/log/grafana
sudo chown -R grafana:grafana /etc/grafana
