May 23, 2007

I was wondering whether anyone can help me, I'm having some major performance problems running PHP on IIS using Shane Caraveo's php_fcgi.dll

PHP: 5.1.1.
IIS: 6

Basically I'm getting to the point where the isapi requests jump rapidly to 400+ requests from a meagre 2 -5 requests. Given the high number of requests this is essentially bringing the server to a standstill.

Does anyone have any ideas how I can begin getting to the bottom of this either through network monitoring or application debugging?

Microsoft FastCGI :: The FastCGI Handler Was Unable To Process The Request

Jan 6, 2008

I installed FastCGI and configured it via fcgiconfig.js using this command

cscript fcgiconfig.js -add -section:"PHP" -extension:php -path:"C:PHPphp-cgi.exe"
It configured fcgiext.ini and added the .php extension to the sites and what not.

When accessing a php script, I get the following error though:

FastCGI Error

The FastCGI Handler was unable to process the request.
Error Details:The FastCGI process exited unexpectedly
Error Number: -2147467259 (0x80004005).
Error Description: Unspecified error
HTTP Error 500 - Server Error.
Internet Information Services (IIS)
I did not do anything special with the PHP. It is the zip 5.2.5 from the site. I configured php.ini and move it to c:/windows. I granted IUSR permission on php-cgi.exe

Am I missing something? I followed the guide here

Windows 2003 / IIS6 / PHP 5.2.5

installing PHP fastcgi on my Centos VPS. I have already Googled for this and tried most of the tutorials but nothing seems to work.

I have already compiled PHP with --enabled-fastcgi. What I ca't figure out is what to put in my .htaccess file.

Almost every tutorial on this compes up with a different way and none of these seem to work for me.

Mod_php Vs. Fastcgi

Jul 6, 2009

I'm looking at optimizing our dynamic content delivery process and there are some interesting claims regarding fastcgi vs. mod_php.

What I am wondering about is assuming apache serving ONLY php content, why would fastcgi perform any better than mod_php? The memory footprint of spawned workers exists in both solutions.

Wouldn't context switches and buffering in fastcgi actually lower performance?

What could be gained by using a different web server (nginx/lighty) ? The primary bottleneck would still be physical memory (assuming <255 workers) ?

PHP 5.25 And Microsoft FastCGI

Dec 7, 2007

I've already posted this over at the vBulletin forums and with their tech support team, but so far no one has been able to find a solution. Someone suggested I post here as well.

I am currently running vB using PHP 4.3.9 with Zend WinEnabler on a windows 2003 server. I have a seperate database server and a web server. This current configuration works fine, but I am moving to an upgraded web server and this is where the problems start.

Due to intermitant issues with Zend WinEnabler (now a discontinued product) I wanted to move to the latest version of PHP (5.2.5 NTS) and Microsoft FastCGI. The problem is that I am getting blank pages when clicking the Today's Post link from the top menu and immediately following the submission of a new post. I've gone through all of the vBulletin listed suggestions about trouble shooting blank pages and none apply.

Because I have a seperate database sever, I am accessing the same database with the new server vB configuration I am migrating to. As such I suspect the issue has to be related to web server given there are no issues on the current live site and the only changes are the PHP version and acceleration app.

If anyone has some suggestions, please let me know. I am running out of time on my server migration window before I am going to be billed for two servers.

FastCGI Hello World Test?

Jun 20, 2009

Just moved to a 1and1 managed server in which FastCGI is enabled.

But I'm having problems getting Movable Type to run under fastcgi - which has never been a problem before, even on shared hosts.

Is there a 'hello world'-type test for fastcgi - so I can check if it is enabled?

Security Implications Of FastCGI

Jan 31, 2008

I recently changed one of my development servers from suPHP to FastCGI. I will admit, FastCGI is much quicker at PHP page generation and the system seems much more responsive.

However, I am looking into how FastCGI differs from suPHP in terms of security. Both run as a form of CGI outside of Apache itself -- which in theory is more secure. However, suPHP prevented users from setting insecure permissions (for instance, the max for files was 644, and for folders it was 755) -- something which FastCGI does not appear to do (although it could due to how it runs as a user).

Does anyone have any comments on this? Is there a way to force these same restrictions via FastCGI?

Also, any other comments in regards to the security of FastCGI vs. suPHP? I have run numerous searches and I don't seem to be able to find much. Google just returns a bunch of providers whose 'customers' are celebrating due to the provider choosing to implement FastCGI.

PHP As Apache Module Or As FastCGI

Jan 22, 2007

I have a server running Apache 2 with PHP as an Apache module. There are a few php scripts that use lots of cpu when they run and have lots of hits, but Apache is still running fine and pages and php scripts load pretty fast. I was just wondering if running PHP as fastcgi would use less cpu or make php scripts load faster.

Plesk 12.x / Linux :: PHP 5.3 Run As FastCGi Application

Nov 13, 2014

I setup PHP support to Run as FastCGi Application, and i setup the memory_limit=32M in DOMAIN/etc/php.ini, then i create a php program with ini_set('memory_limit','128M'), it does not according to my settings are limited. How can i limit it , only just use the disable_function = 'ini_set' ? or Was there other methods ? Because, When PHP runs as apache module , i can use the php_admin_value in vhost.conf to limit what i want , it does not limit everything like this (disable_function).

But in "Apache Module" I only can select PHP 5.3.3:

My WebSite doesn't work with FastCGI, only with "Module Apache".

Why I cannot select 5.3.29 with "Module Apache".

FastCGI :: Aborted: (first Read) Idle Timeout (30 Sec)

May 21, 2008

I've got a server with FastCGI that at random produces 500 internal server errors. In the specific account the errors are as follows in the error_log:

[Wed May 21 12:01:29 2008] [error] [client] FastCGI: comm with (dynamic) server "/usr/local/apache2/htdocs/user/php-wrapper" aborted: (first read) idle timeout (30 sec)
[Wed May 21 12:01:29 2008] [error] [client] FastCGI: incomplete headers (0 bytes) received from server "/usr/local/apache2/htdocs/user/php-wrapper"
As you can see this unfortunately does not tell me anything.

Now viewing the apache error_log I see this

[Wed May 21 12:51:11 2008] [warn] FastCGI: scheduled the restart of the last (dynamic) server "/usr/local/apache2/htdocs/user/php-wrapper" process: reached dynamicMaxClassProcs (10)

All warnings so I'm assuming these don't mean anything.

Here's the php-wrapper:

export PHPRC
exec /usr/local/bin/php-cgi

Not a particularly well setup system for users and such but it worked for the user.

The software versions are as follows:

Apache 2.2.8 with Suexec on the FCGI
FastCGI (Latest stable and also tried a CVS version)
PHP 5.2.6
64 bit system

how to go about debugging this?

Plesk 12.x / Linux :: PHP 5.5 FastCGI - Premature End Of Script
