  • Now we need to install some per-required dependencies for the Grafana with the following command.
sudo apt-get install vim wget curl gnupg2 apt-transport-https software-properties-common net-tools -y
  • Run the following command to download and add the Grafana GPG key.
sudo wget -q -O /usr/share/keyrings/grafana.key https://packages.grafana.com/gpg.key
  • Now add the Grafana repository to APT with the following command.
echo "deb [signed-by=/usr/share/keyrings/grafana.key] https://packages.grafana.com/oss/deb stable main" | sudo tee -a /etc/apt/sources.list.d/grafana.list
  • After adding the repository to the server. Now, we need to update the repositories with the following command.

Configure Nginx as a Reverse Proxy for Grafana

To access Grafana on a particular domain or subdomain, we need to configure the Nginx as a reverse proxy for Grafana.

  • To install the Nginx on the server run the following command.
sudo apt-get install nginx -y
  • Start the Nginx service with the following command.
sudo systemctl start nginx
  • To check the Nginx service status run the following command.
sudo systemctl status nginx
Install and Configure Nginx Reverse Proxy
  • After installing the Nginx on the server, create an Nginx virtual host configuration file with the following command.
vim /etc/nginx/conf.d/grafana.conf
  • Copy the paste the following configuration into Nginx virtual host.
server {
        server_name grafana.linuxpanda.com;
        listen 80 ;
        access_log /var/log/nginx/grafana.log;

    location / {
                proxy_pass http://localhost:3000;
                proxy_set_header Host $http_host;
                proxy_set_header X-Forwarded-Host $host:$server_port;
                proxy_set_header X-Forwarded-Server $host;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
}

Replace “grafana.linuxpanda.com” with your desired domain or subdomain from the above configuration file. Save and exit from the file.

  • Now verify whether the Nginx configuration file is valid or not with the following command.
nginx -t

You will get an output like this.

install Nginx service
  • Restart the Nginx service to save and apply the changes on the server with the following command.
sudo systemctl restart nginx
