How to Setting Up an Apache Grafana Reverse Proxy

Grafana is a powerful open-source platform for monitoring and observability, widely used for visualizing metrics and logs. When serving Grafana in production environments, it’s often beneficial to use a reverse proxy, and Apache HTTP Server is a popular choice for this purpose. This setup is commonly known as Grafana Reverse Proxy Using Apache, providing better control, security, and accessibility.

What is an Apache Grafana Reverse Proxy?

An Apache Grafana reverse proxy is a configuration where the Apache web server forwards client requests to the Grafana server. Essentially, Apache acts as an intermediary, receiving requests from users and routing them to Grafana, which then responds with the requested data.

Advantages of Using a Reverse Proxy for Grafana

• Enhanced Security :- Apache can handle SSL/TLS encryption, authentication, and access control, protecting Grafana from unauthorized access and attacks.
• Improved Performance :- Apache can cache responses and optimize connections, helping to reduce load on the Grafana server.
• Simplified Management :- A reverse proxy allows you to manage multiple Grafana instances or other web applications behind a single Apache server.

By setting up Apache as a reverse proxy, you create a more secure and efficient Grafana deployment.

Steps to Set Up an Apache Grafana Reverse Proxy

Step 1: Install Apache

Begin by installing the Apache web server on your server or workstation. This can typically be done using your system’s package manager:

sudo apt update

sudo apt install apache2

Step 2: Install Grafana

Next, install Grafana on the server. The latest version can be downloaded from the Grafana website.

By default, Grafana runs on port 3000. Ensure Grafana is configured to listen on the correct port.

Step 4: Configure Apache as a Reverse Proxy

Now set up Apache to forward requests to Grafana. Open the Apache configuration file or create a new virtual host for Grafana:

<VirtualHost *:80>
    ServerName grafana.test.com

    ProxyPreserveHost On
    ProxyPass / http://localhost:3000/
    ProxyPassReverse / http://localhost:3000/

    ErrorLog ${APACHE_LOG_DIR}/grafana_test_error.log
    CustomLog ${APACHE_LOG_DIR}/grafana_test_access.log combined
</VirtualHost>

• ServerName :- The domain name for your Grafana instance.
• ProxyPass and ProxyPassReverse :- Forward requests to Grafana running on port 3000.
• Logging directives :-  Help track access and errors.

Step 5: Enable Required Apache Modules

Ensure that the required Apache modules are enabled:

sudo a2enmod proxy
sudo a2enmod proxy_http
sudo a2enmod rewrite
sudo a2enmod headers

Step 6: Restart Apache

After configuring Apache, restart it to apply the changes:

sudo systemctl restart apache2

Step 7: Verify the Configuration

Open a web browser and navigate to your Grafana domain: http://grafana.test.com

You should see the Grafana login page. Logging in confirms that Apache is successfully proxying requests to Grafana.

Conclusion

Setting up an Apache Grafana reverse proxy provides enhanced security, better performance and easier management of your Grafana dashboards. By following these steps, you can secure Grafana to your users while leveraging Apache’s robust features.
