Prerequesites for running HTTP2 along with your Apache2 server

As we strive on getting the latest builds, we constantly update our server to keep it the most secure as possible, so issuing those commands above got us quickly to the point :

HTTP2 on Apache2

Our Apache2 server at the moment we are writing is at version 2.4.25 (# apache2ctl -version). The module is included with Apache2 and we only had to enable it and use it within our website. For more details about Apache2 and HTTP2, I invite you to read the page on Apache.org.

In order to run your server with http/2, you must meet the following requirements :

  • Version of Apache2 : 2.4.17 minimum

The rest is obvious, in the case you don’t have this version on your server, you may need to refer to our article on securing your web server (the link will be displayed here – currently updating).

 

What I will gain using Http/2 protocol ?

There is a whole page you can read to learn more about HTTP/2 from GitHub,

Now that you’ve set up your Apache server along with HTTP/2, I hope you enjoyed these lines and invite you to post any suggestions/questions here. I’ve also made a tutorial on implementing HTTPS, I will post it here soon.
