Apache for Newbie: Set up Apache with mod_http2

Apache is one of the most popular web servers in the world, known for its reliability, flexibility, and performance. If you are new to Apache and want to enhance your website’s speed and security, setting up Apache with mod_http2 is a great option. In this article, we will guide you through the process of setting up Apache with mod_http2, step by step.

What is Apache?

Apache is an open-source web server software that powers millions of websites worldwide. It is known for its stability, security, and ability to handle high traffic loads. Apache supports various operating systems, including Linux, Windows, and macOS, making it a versatile choice for web hosting.

What is mod_http2?

mod_http2 is an Apache module that enables HTTP/2 support on your web server. HTTP/2 is the latest version of the HTTP protocol, designed to improve website performance by reducing latency and increasing throughput. With mod_http2, you can take advantage of the benefits offered by HTTP/2, such as multiplexing, server push, and header compression.

Step 1: Install Apache

The first step is to install Apache on your server. The installation process may vary depending on your operating system. For example, on a Linux system, you can use the package manager to install Apache. On a Windows system, you can download the Apache installer from the official website and follow the installation wizard.

Step 2: Enable mod_http2

Once Apache is installed, you need to enable the mod_http2 module. Open the Apache configuration file (httpd.conf) in a text editor and locate the line that starts with “LoadModule http2_module”. If the line is commented out (starts with a “#”), remove the “#” to enable the module. Save the changes and restart Apache for the changes to take effect.

Step 3: Configure Virtual Hosts

Next, you need to configure virtual hosts in Apache to enable HTTP/2 for your websites. Open the Apache configuration file again and locate the section for virtual hosts. Add the following lines inside the virtual host block:


<VirtualHost *:443>
    Protocols h2 http/1.1
    ServerName example.com
    DocumentRoot /var/www/html
    SSLEngine on
    SSLCertificateFile /path/to/certificate.crt
    SSLCertificateKeyFile /path/to/private.key
</VirtualHost>

Replace “example.com” with your domain name and “/var/www/html” with the path to your website’s document root. Also, make sure to provide the correct paths to your SSL certificate and private key files. Save the changes and restart Apache.

Step 4: Test HTTP/2

To verify that HTTP/2 is enabled on your Apache server, you can use various online tools or browser extensions. One popular tool is the “HTTP/2 and SPDY indicator” extension for Google Chrome. Install the extension and visit your website. If the extension’s icon turns green, it means that your website is using HTTP/2.
