How to Enable HTTP/2 in Apache 2.4 on Ubuntu 20.04

Based on https://gist.github.com/GAS85/8dadbcb3c9a7ecbcb6705530c1252831

Requirements

  • A self-managed VPS or dedicated server with Ubuntu 20.04 running Apache 2.4.xx.
  • A registered domain name with working HTTPS (TLS/SSL). HTTP/2 only works alongside HTTPS because most browsers, including Firefox and Chrome, don’t support HTTP/2 in cleartext (non-TLS) mode.

Step 1: Install Apache2

Per default it will be apache2 version 2.4.41 what is enought for http2 support.

Activating HTTP Public Key Pinning (HPKP) on Let's Encrypt

Activating HTTP Public Key Pinning (HPKP) on Let's Encrypt

Source: https://lilleengen.io/blog/index.php/posts/activating-http-public-key-pinning-hpkp-on-lets-encrypt

  • Disclaimer: This might break your website, don't preceded if you don't know what you're doing.

Since the letsencrypt seems to create a new private key every time the certificate is renewed and Let's Encrypt requires you to renew you certificate once every ~80 days pinning using your certificate's SPKI is probably not the way to go. So, what should we pin then? Let's Encrypt is currently issuing from Authority X3, and using Authority X4 as a backup, so these two is a great place to start. We should also include the ISRG Root so this might support new Authorities with other SPKIs as well.

Generate HASH of Private Keys

To generate the hash of the SPKI of these certificates run the following commands

Apache2 Restrict direct IP access to website

Just added this into Apache2 config. E.g. /etc/apache2/sites-available/900-restrictDirectIP.conf and enable it afterwards.

<VirtualHost 192.168.0.1:80>
	ServerName 192.168.0.1
	Redirect 403 /
	ErrorDocument 403 "Sorry, direct IP access not allowed."
	DocumentRoot /var/www/html
