Enable HTTP/2 on Ubuntu 20.04 with Apache2 and PHP7.4

h2

#!/bin/bash

sudo a2enmod http2 

sudo a2dismod php7.4  
sudo a2dismod mpm_prefork
sudo a2enmod mpm_event proxy_fcgi setenvif
sudo apt install php7.4-fpm -y
sudo systemctl start php7.4-fpm
sudo systemctl enable php7.4-fpm
sudo a2enconf php7.4-fpm
sudo systemctl restart apache2
sudo systemctl restart php7.4-fpm

echo "Add the following line to /etc/apache2/apache2.conf"
echo -e "\tProtocols h2 h2c http/1.1/n/n"

echo "vim /etc/apache2/apache2.conf"

echo -e "/n/nBe sure to mirror any php.ini settings such include_path, memory_limit, ect in /etc/php/7.4/fpm/php.ini/n/n"

echo "vim /etc/php/7.4/fpm/php.ini"

If you need to update /etc/php/7.4/fpm/php.ini do not forget to restart the php7.4-fpm service.

sudo systemctl restart php7.4-fpm

Be sure to restart Apache after updating /etc/apache2/apache2.conf

sudo systemctl restart apache2

If you do not want to enable this globally you may add the following line to a target vhost file

Protocols h2 http/1.1

To run this as a shell do not forget to make it executable

chmod +x h2
./h2
