Enable HTTP2 for Centos 7 via Yum

By default the Centos 7 Apache version uses version 2.4.6. by default and cannot be downgraded or upgraded. Apache version 2.4.6 does not come with the mod_http2.so module which is a component for HTTP/2.

Here is how to enable HTTP2 on centos 7 via yum.

yum install centos-release-scl
yum install httpd24

Check if the mod_http2.so module has been updated.

grep -r http2 /opt/rh/httpd24/root/etc/httpd/ /opt/rh/httpd24/root/etc/httpd/conf.modules.d/00-base.conf:LoadModule http2_module modules/mod_http2.so

Then verify the syntax.

scl enable httpd24 -- bash -l

Then enable the new httpd.

systemctl disable --now httpd
systemctl enable --now httpd24-httpd

Congratulations! Your httpd is now equipped with the HTTP/2 module!
