• Description:
  Grafana is an open-source platform for monitoring and observability. It allows you to visualize metrics from data sources like Prometheus, MySQL, and more. On Ubuntu/Debian, Grafana is not available in the default APT repositories, so you need to add the official Grafana repository, import its GPG key, install Grafana, start the service, and access it via a web browser. The default web interface runs on port 3000.

•  Step 1 — Update System and Install Dependencies
   Update system:

  sudo apt update
        

   Install required dependencies:

  sudo apt install -y software-properties-common wget apt-transport-https gnupg
        

   software-properties-common → allows adding repositories
   wget → for downloading files
   apt-transport-https → allows HTTPS repositories
   gnupg → for GPG key verification
•  Step 2 — Add Grafana GPG Key
   Add Grafana GPG key:

  wget -q -O - https://packages.grafana.com/gpg.key | sudo gpg --dearmor -o /usr/share/keyrings/grafana-archive-keyring.gpg
        

   Ensures APT trusts the Grafana repository.
•  Step 3 — Add Grafana APT Repository
   Add Grafana OSS repository:

  echo "deb [signed-by=/usr/share/keyrings/grafana-archive-keyring.gpg] https://packages.grafana.com/oss/deb stable main" | sudo tee /etc/apt/sources.list.d/grafana.list
        

   Points APT to the official Grafana OSS repository.
•  Step 4 — Update Package List
   Update package list:

  sudo apt update
        

   Now the grafana package is available.
•  Step 5 — Install Grafana
   Install Grafana:

  sudo apt install grafana -y
        

   Installs Grafana server and CLI tools.
•  Step 6 — Start and Enable Grafana Service
   Start and enable Grafana:

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

   Starts Grafana service and ensures it runs on boot.
   Default Grafana port: 3000
•  Step 7 — Find Server IP
   Check IP address:

  ip a
        

   Look for inet <IP_ADDRESS> under your active network interface.
   Example: 192.168.1.50
•  Step 8 — Open Grafana in Browser
   Local machine:
  http://localhost:3000
  
   Remote server:
  http://<server-ip>:3000
•  Step 9 — Login
   Username: admin
   Password: admin(Grafana@123) → you will be prompted to change it on first login.
