Step 1: Update Your System

Before making any changes, ensure your system is up to date. Run the following commands:

sudo apt update && sudo apt upgrade -y

Keeping your system updated is crucial for security and performance, whether you're setting it up locally or on a VPS Windows Servers platform.

Step 2: Install Apache

If Apache is not already installed, you can install it using:

sudo apt install apache2 -y

Step 3: Enable Apache Modules

To use HTTP/2, you need to enable the necessary Apache modules. Run the following commands:

sudo a2enmod headers
sudo a2enmod ssl
sudo a2enmod http2
            

Step 4: Configure Apache for HTTP/2

Edit your Apache configuration file to enable HTTP/2. If you are using the default configuration, you can edit the following file:

sudo nano /etc/apache2/sites-available/000-default.conf

Add the following lines within the <VirtualHost *:443> block:

Protocols h2 http/1.1
            

Your configuration should look like this:

    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html

    Protocols h2 http/1.1

    SSLEngine on
    SSLCertificateFile /path/to/your/certificate.crt
    SSLCertificateKeyFile /path/to/your/private.key

            

Step 5: Restart Apache

After making the changes, restart Apache to apply them:

sudo systemctl restart apache2

Step 6: Verify HTTP/2 Support

To verify that HTTP/2 is enabled, you can use an online tool like KeyCDN's HTTP/2 Test. Enter your domain, and it will tell you if HTTP/2 is supported.
