Enable HTTP2 in Apache on Ubuntu 16.04

Posted on May 11, 2016
Ubuntu 16.04 Apache Server Optimization
Asked by Florian Lehmuth

Hi there,

I’ve recently created a new droplet with Ubuntu 16.04 and was pleased to see that sudo apt-get install apache2 gets me Apache 2.4.18. I was hoping that would allow me to enable HTTP2 support; alas, the respective mod_http2 is not included. Is there any way to manually install the module or to get a version of Apache that has it included?

Many thanks, Florian

Another option is using Ondrej’s Launchpad PPA. For example: (replacing REPOSITORY with string from that page for your Ubuntu version).

sudo add-apt-repository 'REPOSITORY'
sudo apt-get update
sudo apt-get dist-upgrade

This will give you the latest Apache rather than the version specifically for Ubuntu. Of course there are reasons Ubuntu ships slightly differently - stability, known degree of security/performance testing etc. but in my mind it is a worthwhile tradeof especially for HTTP/2

It was working fine for me but when I updated it recently it rolled back to HTTP 1.1, so I am looking out for answers who knows how to resolve this.

Please try if you know what you are doing. Neither Ubuntu nor other UNIX platforms support out of the box HTTP2 protocols. It is not recommended to run HTTP2 with these configurations on the production server unless you want to play along with it.
