SDB:Apache HTTP 2 configuration
(Redirected from Apache HTTP 2 configuration)
You need to install Apache 2.4.0 or newer. For older openSUSE Leap systems, please download from OBS.
mod_php only works with prefork, so you have to switch to FactCGI + PHP-FPM.
How to
Install Apache2:
sudo zypper install apache2
Enable http2 mod:
sudo a2enmod http2
Enable HTTP2 flag:
sudo a2enflag HTTP2
Switch from prefork to event:
sudo zypper remove apache2-prefork sudo zypper install apache2-event
For PHP websites, you have to switch from apache2-mod_php7 to php7-fpm.
As always, restart Apache:
sudo systemctl restart apache2
Explanation
Other OS will let you to modify *.conf files. However, openSUSE/SLE makes the solution simpler.
You can find a file
/etc/apache2/protocols.conf
which detects if apache2 has enabled http2 mod and been given HTTP2 flag. If both conditions are satisfied, Apache will enable HTTP/2 protocol.
Enabled mods and flags are stored in
/etc/sysconfig/apache2
You should avoid editing them directly. Use a2enmod/a2dismod and a2enflag/a2disflag commands instead.
