Hi,
I am trying to run PHP via FastCGI on a Windows 2008 server. I followed this installation doc http://learn.iis.net/page.aspx/246/using-fastcgi-to-host-php-applications-on-iis7/ and have checked I completed the steps correclty numerous times. However when I try to execute a php page i am presented with the following error:
HTTP Error 500.0 - Internal Server Error
C:\PHP\php-cgi.exe - The FastCGI process exited unexpectedly
Detailed Error Information
Module: FastCgiModule
Notification: ExecuteRequestHandler
Handler: PHP via FastCGI
Error Code: 0x000000ff
Requested URL: localhost/test.php
Physical Path: C:\inetpub\wwwroot\test.php
Logon Method: Negotiate
Logon User: Domain\user
I had PHP working correctly without using FastCGI so im fairly sure its not the PHP installation. The only help i have found on this error is here http://blogs.iis.net/rickjames/archive/2007/10/16/fastcgi-debugging-quot-the-fastcgi-process-exited-unexpectedly-quot.aspx and as I am a novice at debugging something like this im not finding it much help.
I have changed the applictaionhost.config file locking down most sections as this server wiil be used for hosting, but i have doubled checked that the sites attempting to run php have access to all the modules and handlers they require i.e. the FastCGI handler shown above in the detailed error information.
Any ideas on why this error may be happening, or any simple tips for debugging it?
I am thinking a fresh install may be my only way of fixing this?
*****Update*****
After reading other posts I followed these steps mentioned by ruslany
"A possible way to isolate the problem is by running your script from the command line:
C:\php\php-cgi.exe C:\inetpub\wwwroot\phpinfo.php
If you get the same error then you will know that the error has nothing to do with web server or FastCGI module.
Another thing to try is to switch php handler mapping from FastCGI to CGI and see if the error goes away. This way you will know that the error is caused by FastCGI."
So I ran the script from the command line and it returned:
-----------------------------------------------------------------------------------
PHP Warning: PHP Startup: Unable to load dynamic library 'C:\Program Files (x86)\PHP\ext\php_gd.dll' - The specified module could not be found. in Unknown on line 0
Hello World!
----------------------------------------------------------------------------------
I then switched the php handler from FastCGI to CGI and tried my php page using IE which returned the "Hello World" text followed by the php warning above
So, bar the warning it appears to be working correctly. I dont think this warning is crashing FastCGI, however ill work on fixing it just to make sure.
