Virtualmin: "PHP execution via fcgid requires the Apache mod_fcgid module"

I have a CentOS server with Virtualmin on it. I have configured PHP the way I want it, using Apache mod_fastcgi. However, when I click "Re-check Config" in Virtualmin, I get

PHP execution via fcgid requires the Apache mod_fcgid module

This post says to change Default PHP execution mode to CGI, but I can't find such an option anywhere!

• For now, I solved it by enabling mod_fcgid in Apache but just not configuring it. But that's wasting memory, and I'd love to know the "proper" way to solve this!

  Josh : UG. This solution is causing all sorts of other issues with the newest version of Virtualmin...
  From Josh

• mod_fastcgi (www.fastcgi.com) is a 3rd-party module whose directives have a "FastCgi" prefix.

  mod_fcgid http://httpd.apache.org/mod_fcgid/mod/mod_fcgid.html is an Apache module whose directives have a "Fcgid" prefix.

  I advise that you remove mod_fastcgi and go with mod_fcgid.

  That's great news for PHP, because then you can dump apache mpm-prefork and go with the better mpm-worker, by not installing mod_php, instead use php as fast cgi. For debian, this means:

  • Remove apache2-mpm-prefork and libapache2-mod-php5.

  • Add apache2-mpm-worker, libapache2-mod-fcgid, and php5-cgi. With php5-cgi, you don't need a custom fast cgi wrapper, you can use the php command-line itself directly (notice the /usr/lib/cgi-bin/php5) below.

  • For mod_fcgid with PHP, note that PHP as FastCGI has its own facility for terminating after handling so many requests (see PHP_FCGI_MAX_REQUESTS). FcgidMaxRequestsPerProcess helps avoid sending additional requests to the wrapper application after it has handled its limit.

  • Inside each virtual host or at global scope:

      FcgidInitialEnv PHP_FCGI_MAX_REQUESTS 200
      FcgidMaxRequestsPerProcess 200
  

  • Then inside Directory:

      AddHandler fcgid-script .php
      FcgidWrapper /usr/lib/cgi-bin/php5 .php
      Options +ExecCGI
  

  Josh : I'm using Apache mpm_worker. The issue is that I want mod_fastcgi and Virtualmin wants mod_fcgid. I have FastCGI working perfectly and don't want to switch it. The question was, how can I make Virtualmin run without installing mod_fcgid?
