Now that HTTP/2 is fairly stable and widely available, I decided to try and install and run it on this server. I’m currently running the Ubuntu 16.04.2 LTS with virtual hosts configured so I can serve a number of sites beyond this one. All of the sites this server hosts are also served securely using certificates from LetsEncrypt.
To install HTTP/2 I SSH’d in to the server and ran the following commands:
# add the new apache repository to your server's sources
sudo add-apt-repository -y ppa:ondrej/apache2
# update apache
sudo apt-key update
sudo apt-get update
# WARNING: answering yes at the prompts following this command will overwrite your apache.conf file located in /etc/apache2
sudo apt-get --only-upgrade install apache2 -y
# enable http2
sudo a2enmod http2
Next, navigate to /etc/apache2/sites-available and edit a virtual file of your choice, adding the following line after the ServerName declaration:
Protocols h2 h2c http/1.1
Finally, restart apache:
sudo service apache2 restart
Your site should now be served using http2. You can verify this using the KeyCDN tool located here.
Did I miss anything? Let me know.
