Apache 2.4 Http2

If you haven’t already converted your webserver to support HTTP2, it’s about time to get this process done. Enabling support for HTTP2 on your website and webserver is a very easy process. It shouldn’t take more than a few minutes and cause almost no down-time.

If you find an Apache version =2.4.29 you find instructions how to update Apache here: Upgrade Apache for HTTP/2. Otherwise your are ready to continue with the following steps. First you have to install the SSL and HTTP/2 module. SSL is requiread by the HTTP/2 protocol. Once the PPA is added, update and upgrade Apache: sudo apt update sudo apt upgrade This will update and upgrade apache2 to Apache 2.4.33+. Step 2: Tell Apache to use PHP FastCGI. You want to make Apache use a compatible PHP implementation by changing modphp to php-fpm (PHP FastCGI).

The process to configure your Apache web server to support HTTP2 is simple. During this process we will be adding repositories to our package manager lists. We will be updating your package manager and then install a few software packages. At that point we will be performing some minor configuration changes. These instructions are listed for Ubuntu 18.04 LTS but should be mostly compatible with derivative OSes that uses this Linux distribution as it’s base.

So, let’s open your favorite CLI and get started. We assume that the apache2 module is already installed on your server and running. Furthermore, you should make sure to have an Apache version >=2.4.29 since earlier versions do not support HTTP/2. If you want to check your Apache version simply type:

To do so open the apache configuration file with a text editor of your choice. Usually you will find it at the location:</p><p><br />The only thing you have to do is to add the following lines to this configuration. </p><p>You can do this either globally or for a particular virtual host only.
