The PHP/Apache configuration that is distributed in the Red Hat family is "FastCGI Process Manager" (FPM).
I don't know if anything else in the RHEL distributions use FastCGI.
$ rpm -qi php-fpm | grep ^Summary
Summary : PHP FastCGI Process Manager
What you're looking for is mod_proxy_fcgi, not FPM. It's included in Fedora's httpd-core package; I don't know about RHEL: https://packages.fedoraproject.org/pkgs/httpd/httpd-core/fed...
I'm not looking for anything. I use this now, and it works.
I don't really know anything about the FastCGI.
