How to Install Grafana on Linux Server for DevOps Monitoring (Step-by-Step Beginner Guide)

If you're setting up monitoring for your Linux server, Grafana is one of the best tools you can use. In this guide, you’ll learn how to install Grafana on a Linux server step by step, with real commands and simple explanations that are easy to follow—even if you're just starting out.

Step 1: Update Your Linux Server

Start by updating your system to make sure all packages are up to date and secure.

sudo apt update
sudo apt upgrade -y

If you encounter a 429 Too Many Requests error while running apt update or apt upgrade, it’s a common issue. You can fix it easily by following this guide: How to Fix 429 Too Many Requests Error in Ubuntu APT Update

This ensures your server is running the latest updates and avoids installation issues later.

Step 2: Install Required Packages

sudo apt install wget curl software-properties-common net-tools -y

These tools help with downloading Grafana and checking network-related configurations.

Step 3: Add Grafana Repository

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

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

Step 4: Install Grafana

sudo apt update
sudo apt install grafana -y

Step 5: Start and Enable Grafana Service

sudo systemctl start grafana-server
sudo systemctl enable grafana-server
sudo systemctl status grafana-server

Step 6: Verify Grafana Port

netstat -tpln

Step 7: Access Grafana in Browser

http://your-server-ip:3000

• Username: admin
• Password: admin

Step 8: First Password Change

After logging in with the default credentials, Grafana will prompt you to change the password. This is an important security step and should not be skipped.

Step 9: Grafana Dashboard

Step 10: Configure Firewall

If you want to access Grafana from an external network or public IP, you need to allow port 3000 through the firewall.

sudo ufw enable
sudo ufw allow 3000/tcp
sudo ufw reload

This step ensures that external users can access the Grafana dashboard securely through your server’s IP address.

Final Thoughts
