IBM HTTP Server (Apache2) error - php

Question

I have configured IBM HTTP Server as follow:
<IfModule mod_fastcgi.c>
Options Indexes MultiViews ExecCGI
FastCGIServer "c:/php7.1/php-cgi.exe"
SetHandler fastcgi-script
</IfModule>
<Directory "C:/IBM/HTTPServer85/htdocs/public">
AddHandler fastcgi-script .php
Options FollowSymLinks Indexes MultiViews ExecCGI
AllowOverride None
Order allow,deny
Allow from all
</Directory>
I get the following errors:
[Mon Jan 29 12:17:22 2018] [notice] Child 8328: Starting 600 worker threads.

What is wrong with my http.conf?

Answer 1

It looks like you have a hybrid/partial config of multiple ways to configure fastcgi.
In the era of mod_fastcgi (IHS 8.5.5 and earlier), you'd typically see the "Action" directive here which results in a request for foo.php to be passed to the PHP interpreter as an argument.
Since you don't have action, and your SetHandler does not limit to
any particular extension, mod_fastcgi tries to invoke your php script
directly as an executable. On Windows, this association of what intepreter to use is the global one of the OS.
If you stick with mod_fastcgi, I'd suggest using the boilerplate examples with Action you see everywhere. But there's no reason to torture yourself with this when even IHS 9 has mod_proxy_fcgi and you could instead configure that and php-fpm instead.
