Hello,
The install puts either HTTPs config, in the form of zzzkaltura.ssl.conf which points to /opt/kaltura/app/configurations/apache/kaltura.ssl.conf or none SSL config:
# ll /etc/httpd/conf.d/zzzkaltura.conf
lrwxrwxrwx. 1 root root 51 Mar 15 15:34 /etc/httpd/conf.d/zzzkaltura.conf -> /opt/kaltura/app/configurations/apache/kaltura.conf
If you want to redirect HTTP to HTTPs, I suggest you add that in a separate file under /etc/httpd/conf.d
reason why I say a separate one, is so that it is not overridden by upgrades.
So something like:
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}
in a file that is parsed first, should suffice.
