HTTP/2

• Modul Apache HTTP/2 aktivieren:

a2enmod http2

• Protokoll für HTTP/S Site aktivieren:

<VirtualHost *:80>
   Protocols h2 h2c http/1.1
...
<VirtualHost *:443>
   Protocols h2 h2c http/1.1
...

• Apache neu starten:

systemctl restart apache2

• Kontrolle:

curl -vso /dev/null --http2 https://<site>
...
* Using HTTP2, server supports multi-use
* Connection state changed (HTTP/2 confirmed)
* Copying HTTP/2 data in stream buffer to connection buffer after upgrade: len=0
* Using Stream ID: 1 (easy handle 0x7ffa00805200)
> GET / HTTP/2
...

• PHP Unterstützung bei Umstellung mpm-prefork nach mpm-event (Stand Debian Stretch):

apt install libapache2-mod-fcgid php7.0-fpm
a2dismod php7.0
a2dismod mpm_prefork
a2enmod mpm_event
a2enmod actions fcgid proxy_fcgi alias setenvif
a2enconf php7.0-fpm
systemctl reload apache2
