Overview

The FastCGI module in IIS enables popular application frameworks that support the FastCGI protocol to be hosted on the IISweb server in a high-performance and reliable way. FastCGI provides a high-performance alternative to the CommonGateway Interface (CGI), a standard way of interfacing external applications with Web servers that has been supported aspart of the IIS feature-set since the very first release.

CGI programs are executables launched by the web server for each request in order to process the request and generatedynamic responses that are sent back to the client. Because many of these frameworks do not support multi-threadedexecution, CGI enables them to execute reliably on IIS by executing exactly one request per process. Unfortunately, itprovides poor performance due to the high cost of starting and shutting down a process for each request.

FastCGI addresses the performance issues inherent in CGI by providing a mechanism to reuse a single process over andover again for many requests. Additionally, FastCGI maintains compatibility with non-thread-safe libraries by providing a poolof reusable processes and ensuring that each process will only handle one request at a time.

Enabling FastCGI Support in IIS 7.0

Windows Server 2008

Add the CGI role service by going to Server Manager -> Roles -> Add Role Services. This enables both the CGI andFastCGI services:

Windows Vista SP1

Add the CGI feature by going to Control Panel -> Programs and Features -> Turn Windows features on or off. This enablesboth the CGI and FastCGI services.

IMPORTANT: Install the update for FastCGI module

The update for IIS 7.0 FastCGI module fixes several known compatibility issues with popular PHP applications. Install theupdate from one of the following locations:

Update for Windows Server 2008 Update for Windows Server 2008 x64 Edition Update for Windows Server 2008 for Itanium-based Systems Update for Windows Vista SP1 Update for Windows Vista SP1 for x64 based Systems

Install Administration Pack for IIS 7.0

NOTE: This step is optional.

Among other useful features Administration Pack for IIS 7.0 has a very convenient user interface for configuring FastCGIsettings. Administration Pack can be installed from these locations:

Administration Pack for IIS 7.0 - x86 Administration Pack for IIS 7.0 - x64

Install and Configure PHP

It is recommended to use a non-thread safe build of PHP with IIS 7.0 FastCGI. A non-thread safe build of PHP providessignificant performance gains over the standard build by not doing any thread-safety checks, which are not necessary, sinceFastCGI ensures a single threaded execution environment.

1. Download the latest non-thread safe zip package with binaries of PHP from http://www.php.net/downloads.php.2. Unpack the files to a directory of your choice (e.g. C:\PHP). Rename the php.ini-recommended to php.ini.3. Open the php.ini file, then uncomment and modify settings as follows:

o Set cgi.fix_pathinfo=1. cgi.fix_pathinfo provides *real* PATH_INFO/PATH_TRANSLATED support for CGI.PHP's previous behavior was to set PATH_TRANSLATED to SCRIPT_FILENAME, and to not care whatPATH_INFO is. For more information on PATH_INFO, see the cgi specs. Setting this to 1 will cause PHPCGI to fix its paths to conform to the spec

o Set cgi.force_redirect = 0.o Set fastcgi.impersonate = 1. FastCGI under IIS supports the ability to impersonate security tokens of the

calling client. This allows IIS to define the security context that the request runs under.o Set fastcgi.logging = 0.o Set open_basedir to point to a folder or network path where the content of the web site(s) is located.o Set extension_dir to point to a location where PHP extensions reside. Typically, for PHP 5.2.X that would

be set as extension_dir = "./ext"o Set date.timezone = Asia/Bangkok to work in Thailand location.o Enable the required PHP extension by un-commenting corresponding lines, for example:

extension=php_mssql.dllextension=php_mysql.dll

4. To test if the PHP installation is successful, run the following from the command line prompt:

C:\PHP>php –info

If PHP was installed correctly and all its dependencies are available on the machine, then this command will output thecurrent PHP configuration information.

Configure IIS 7.0 to Handle PHP Requests

In order for IIS 7.0 to host PHP applications, it is necessary to add a handler mapping that tells IIS to pass all PHP specificrequests to the PHP application framework via FastCGI protocol.

Using IIS Manager

Open IIS Manager and then select and open “Handler Mappings” at the server level:

Select the “Add Module Mapping” action and specify the configurations settings as below:

Request path: *.php Module: FastCgiModule Executable: "C:\[Path to your PHP installation]\php-cgi.exe" Name: PHP via FastCGI

Click OK. A dialog box appears asking if you want to create a FastCGI application for this executable. Click Yes.

Test that the handler mapping works correctly by creating a phpinfo.php file in the C:\inetpub\wwwroot folder that containsthe following code:

<?php phpinfo(); ?>

Open a browser and navigate to http://localhost/phpinfo.php. If everything was setup correctly, then you will see the standardPHP information page:

NOTE: If you do not see "FastCgiModule" in the "Modules:" drop-down list then it means that the module is not registered ornot enabled. To check if FastCGI module is registered open the IIS configuration file%WINDIR%\windows\system32\config\applicationHost.config and check that the following line is present in <globalModules>section:

<add name="FastCgiModule" image="%windir%\System32\inetsrv\iisfcgi.dll" />

Also, in the same file, check that the FastCGI module is added to the <modules> section:

<add name="FastCgiModule" />

Using command line

Alternatively, the above mentioned steps can be completed by using command line tool appcmd.

To create the FastCGI application process pool, run the following command:

C:\>%windir%\system32\inetsrv\appcmd set config /section:system.webServer/fastCGI /+[fullPath='c:\{php_folder}\php-cgi.exe']

After that, create the handler mapping:

C:\>%windir%\system32\inetsrv\appcmd set config /section:system.webServer/handlers/+[name='PHP_via_FastCGI',path='*.php',verb='*',modules='FastCgiModule',scriptProcessor='c:\{php_folder}\php-cgi.exe',resourceType='Unspecified']

Note: If you are using PHP version 4.X, instead of php-cgi.exe, you can use php.exe.

Best Practices for Configuring FastCGI and PHP

This download contains a summary presentation on Best Practices for hosting PHP in a shared hosting environment.

Security Isolation for PHP Web Sites

The recommendation for isolating PHP web sites in a shared hosting environment is consistent with all general securityisolation recommendations for IIS 7.0. In particular, it is recommended to:

Use one application pool per web site Use a dedicated user account as an identity for the application pool Configure anonymous user identity to use the application pool identity Ensure that FastCGI impersonation is enabled in the php.ini file (fastcgi.impersonate=1)

For more details about security isolation in a shared hosting environment, refer to Isolating Sites with Application Pools.

PHP Process Recycling Behavior

Make sure that FastCGI always recycles the php-cgi.exe processes before the native PHP recycling kicks in. The FastCGIprocess recycling behavior is controlled by the configuration property instanceMaxRequests. This property specifies howmany requests the FastCGI process will process before recycling. PHP also has a similar process recycling functionality thatis controlled by an environment variable PHP_FCGI_MAX_REQUESTS. By setting instanceMaxRequests to be smaller orequal to PHP_FCGI_MAX_REQUESTS, you can ensure that the native PHP process recycling logic will never kick in.

The FastCGI settings can be configured either by using IIS Manager or by using the command line tool appcmd.

Using IIS manager

To configure FastCGI recycling settings by using IIS Manager, you need to install Administration Pack for IIS 7.0 and thenselect FastCGI settings at the server level:

Next select the FastCGI application that you want to configure and click "Edit..." in the Actions pane on right hand side:

In the "Edit FastCGI application" dialog, set instanceMaxRequest to 10000 and then click on the browse button next to theEnvironmentVariables setting:

Add the PHP_FCGI_MAX_REQUESTS environment variable and set its value to 10000:

Note: If you do not configure these settings, then the following default settings are used: instanceMaxRequests = 200,PHP_FCGI_MAX_REQUESTS = 500 (on most PHP builds).

Using command line

To configure the recycling behavior of FastCGI and PHP via appcmd, use the following commands:

C:\>%windir%\system32\inetsrv\appcmd set config -section:system.webServer/fastCgi /[fullPath='c:\{php_folder}\php-cgi.exe'].instanceMaxRequests:10000

C:\>%windir%\system32\inetsrv\appcmd.exe set config -section:system.webServer/fastCgi /+"[fullPath='C:\{php_folder}\php-cgi.exe'].environmentVariables.[name='PHP_FCGI_MAX_REQUESTS',value='10000']"

PHP Versioning

Many PHP applications may rely on functions or features available only in certain versions of PHP. If such applications are tobe hosted on the same server then different PHP versions must be enabled and running side-by-side. The IIS 7.0 FastCGIhandler fully supports running multiple versions of PHP on the same web server.

For example, let’s assume that on your web server you plan to support PHP 4.4.8, PHP 5.2.1 and PHP 5.2.5 non-threadsafe. To enable that, you must place corresponding PHP binaries in separate folders on the file system (e.g. C:\php448\,C:\php521\ and C:\php525nts) and then create FastCGI application process pools for each version:

C:\>%windir%\system32\inetsrv\appcmd set config /section:system.webServer/fastCGI /+[fullPath='c:\php448\php.exe']

C:\>%windir%\system32\inetsrv\appcmd set config /section:system.webServer/fastCGI /+[fullPath='c:\php521\php-cgi.exe']

C:\>%windir%\system32\inetsrv\appcmd set config /section:system.webServer/fastCGI /+[fullPath='c:\php525nts\php-cgi.exe']

Now, if you have 3 web sites (site1, site2, site3), where each site needs to use a different PHP version, you can definehandler mappings on each of those sites to reference a corresponding FastCGI application process pool.

Note: Each FastCGI process pool is uniquely identified by a combination of fullPath and arguments properties.

C:\>%windir%\system32\inetsrv\appcmd set config site1 –section:system.webServer/handlers/+”..[name=’PHP448_via_FastCGI’,path=’*.php’,verb=’*’,modules=’FastCgiModule’,scriptProcessor=’c:\php448\php.exe’,resourceType=’Either’]

C:\>%windir%\system32\inetsrv\appcmd set config site2 –section:system.webServer/handlers/+”..[name=’PHP521_via_FastCGI’,path=’*.php’,verb=’*’,modules=’FastCgiModule’,scriptProcessor=’c:\php521\php-cgi.exe’,resourceType=’Either’]

C:\>%windir%\system32\inetsrv\appcmd set config site3 –section:system.webServer/handlers/+”..[name=’PHP525nts_via_FastCGI’,path=’*.php’,verb=’*’,modules=’FastCgiModule’,scriptProcessor=’c:\php525nts\php-cgi.exe’,resourceType=’Either’]

PHP Security Recommendations

The following settings can be used to tighten the security of a PHP installation. To make the recommended changes locateand open the php.ini file and edit the configuration settings as described below:

Setting Description

allow_url_fopen=Offallow_url_include=Off

Disable remote URLs for file handling functions, which may cause code injectionvulnerabilities.

register_globals=Off Disable register_globals.

open_basedir="c:\inetpub\" Restrict where PHP processes can read and write on a file system.

safe_mode=Offsafe_mode_gid=Off Disable safe mode

max_execution_time=30max_input_time=60 Limit script execution time

memory_limit=16Mupload_max_filesize=2M Limit memory usage and file sizes

post_max_size=8Mmax_input_nesting_levels=64

display_errors=Offlog_errors=Onerror_log="C:\path\of\your\choice"

Configure error messages and logging

fastcgi.logging=0IIS FastCGI module will fail the request when PHP sends any data on stderr byusing FastCGI protocol. Disabling FastCGI logging will prevent PHP from sendingerror information over stderr, and generating 500 response codes for the client.

expose_php=Off Hide presence of PHP

Enabling per-site PHP configuration

The section describes the recommended way of enabling per-site PHP configuration . Note that this recommendation wasdiscovered and validated by Radney Jasmin with hosting provider GoDaddy.com who now offers PHP hosting on WindowsServer 2008 via FastCGI.

Per-site PHP process pools

When each web site has its own application pool (which is a recommended practice on IIS 7.0), it is possible to associate adedicated FastCGI process pool with each web site. A FastCGI process pool is uniquely identified by the combination offullPath and arguments attributes. So, if it is necessary to create several FastCGI process pools for the same processexecutable, such as php-cgi.exe, the arguments attribute can be used to distinguish process pools definitions. In addition,with php-cgi.exe processes the command line switch "-d" can be used to define an INI entry for PHP process. This switchcan be used to set a PHP setting that makes the arguments string unique.

For example, if there are two web sites "website1" and "website2" that need to have their own set of PHP settings, theFastCGI process pools can be defined as follows:

<fastCgi> <application fullPath="C:\PHP\php-cgi.exe" arguments="-d open_basedir=C:\Websites\Website1" /> <application fullPath="C:\PHP\php-cgi.exe" arguments="-d open_basedir=C:\Websites\Website2" />

</fastCgi>

In this example the PHP setting open_basedir is used to distinguish between process pool definitions. In addition it enforcesthat the PHP executable for each process pool can perform file operations only within the root folder of the correspondingweb site.

Then website1 can have the PHP handler mapping as follows:

<system.webServer> <handlers accessPolicy="Read, Script">

<add name="PHP via FastCGI" path="*.php" verb="*" modules="FastCgiModule" scriptProcessor="C:\PHP\php-cgi.exe|-d open_basedir=C:\Websites\Website1" resourceType="Unspecified" requireAccess="Script" />

</handlers></system.webServer>

and website2 can have the PHP handler mapping as follows:

<system.webServer> <handlers accessPolicy="Read, Script">

<add name="PHP via FastCGI" path="*.php" verb="*" modules="FastCgiModule" scriptProcessor="C:\PHP\php-cgi.exe|-d open_basedir=C:\Websites\Website2" resourceType="Unspecified" requireAccess="Script" />

</handlers></system.webServer>

Specifying php.ini location

When the PHP process starts it determines the location of the configuration php.ini file by using various settings. The PHPdocumentation provides detailed description of the PHP start up process. Note that one of the places where PHP processsearches for php.ini location is the PHPRC environment variable. If PHP process finds a php.ini file in the path specified inthis environment variable then it will use it, otherwise it will revert to default location of php.ini. This environment variable canbe used to allow hosting customers to use their own versions of php.ini files.

For example if there are two websites: website1 and website2; located at the following file paths: C:\WebSites\website1 andC:\WebSites\website2 then the php-cgi.exe process pools in the <fastCgi> section of applicationHost.config can beconfigured as below:

<fastCgi> <application fullPath="C:\PHP\php-cgi.exe" arguments="-d open_basedir=C:\Websites\Website1">

<environmentVariables> <environmentVariable name="PHPRC" value="C:\WebSites\website1" />

</environmentVariables> </application> <application fullPath="C:\PHP\php-cgi.exe" arguments="-d open_basedir=C:\WebSites\Website2">

<environmentVariables> <environmentVariable name="PHPRC" value="C:\WebSites\website2" />

</environmentVariables> </application>

</fastCgi>

This way website1 can have its own version of php.ini in the C:\WebSites\website1, while website2 can have its own versionof php.ini located in C:\WebSites\website2. This configuration also ensures that if there is no php.ini found in locationspecified by PHPRC environment variable then PHP will fall back to using the default php.ini file located in the same folderwhere php-cgi.exe is located.

Providing URL rewriting functionality for PHP applications

The majority of popular PHP applications rely on the URL rewriting functionality in web servers to enable user friendly andsearch engine friendly URL's. IIS 7.0 provides URL rewriting capabilities via the URL rewrite module.

Refer to the following articles for more information on how to use the URL Rewrite Module:

1.i couldn't use any of those commands ...2.i couldn't find any fastcgi module ! it was "CGI Module" for me ...3.when i open my php page it shows what i've entered but there're some garbages along ...it's like 15+ line and they are like this

"specified module could not be found. in Unknown on line 0 PHP Warning: PHP Startup: Unable to load dynamiclibrary 'C:\PHP\ext\php_radius.dll' - The specified module could not be found. in Unknown on line 0 PHP Warning:PHP Startup: Unable to load dynamic library 'C:\PHP\ext\php_rar.dll' ... "

i've installed PHP 5.2.6 on C:\PHP and i'm using Vista x64is that usual or i did something wrong ?

9. Submitted on Jun 17 2008 byscotteredu After some fiddling I was able to get it to work, mostly.

I am using PHP/MYSQL on my Vista box to demo so CMS products and when I go to install I get this:PHP Warning: session_start() [function.session-start]: open_basedir restriction in effect. File(C:\Windows\TEMP\) isnot within the allowed path(s): (c:\local) in C:\local\install\index.php on line 10 PHP Fatal error: session_start()[function.session-start]: Failed to initialize storage module: files (path: ) in C:\local\install\index.php on line 10

I think this is related to the 'open_basedir' line in the config steps above. Removing the reference to my website dir(c:\local) allows the install of the first CMS am testing to carry on.

My qestion is, first how unsecure is it to not have that line confi'd and second, if I do configure it like I did before -what else do I need to add to elminate the error?

very informative write up. Thanks.s

10. Submitted on Jun 24 2008 byruslany The open_basedir is a security protection measure which is useful when the PHP scripts that you deploy onyour server are not trusted. For example, this is important to use in shared hosting scenarios. If you know what yourscript does then you may turn off this setting. Or, alternatively you can configure the PHP session.save_path settingto use file path that is within the scope of the open_basedir restriction.

since php.net does not compile or create these x64 bit versions you have to get them form other sites. presentlyhttp://www.fusionxlan.com/PHPx64.php offers these files.

Please note installation is the same process as described above.

Hope this helps someone as i was tearing my hair to figure this out..26. Submitted on Sep 17 2008 by

shinshi360 FYI - READ THIS!

At the end of this article, there is an appcmd to set PHP_FCGI_MAX_REQUESTS to 10000. Beware of simplycopying and pasting the appcmd line used to set the environment variable for PHP_FCGI_MAX_REQUESTS.

1) As someone already mentioned, removing the extra space between the name and value parameters will allow thecommand to succeed. BUT:

2) If you look closely, the single-quote character used to delimit PHP_FCGI_MAX_REQUESTS is an actual singleclose quote (’) and not a keyboard apostrophe (') as needed by appcmd. The command will succeed but appcmdincorrectly parses the command line. If your console window uses the default system font, they look exactly thesame. The snippet below is the result of the issue:

C:\>%windir%\system32\inetsrv\appcmd list config -section:system.webServer/fastCgisystem.webServer>

fastCgi>application fullPath="C:\php\php-cgi.exe" instanceMaxRequests="10000">environmentVariables>environmentVariable name="10000" />/environmentVariables>/application>/fastCgi>/system.webServer>

Note how name is "10000" and not "PHP_FCGI_MAX_REQUESTS". This is clearly useless.

If you discover that you have this silent error in your configuration, you can edit your%windir%\system32\inetsrv\config\applicationHost.config file to change

environmentVariable name="10000" />

into

environmentVariable name="PHP_FCGI_MAX_REQUESTS" value="10000" />

or follow the commands below:

%windir%\system32\inetsrv\appcmd set config -section:system.webServer/fastCgi /-[fullPath='c:\php\php-cgi.exe'].environmentVariables.[name='10000']

%windir%\system32\inetsrv\appcmd set config -section:system.webServer/fastCgi /+[fullPath='c:\php\php-cgi.exe'].environmentVariables.[name='PHP_FCGI_MAX_REQUESTS',value='10000']

If the configuration has been updated correctly, you should see an entry for PHP_FCGI_MAX_REQUESTS set to10000 in your phpinfo under the Environment section.

Feel free to delete this comment if the article has been updated and this is no longer needed!29. Submitted on Oct 06 2008 by

ruslany Shinshi360, thanks for finding the error in the appcmd command! I have updated the article with the correctappcmd syntax.

30. Submitted on Oct 15 2008 byJohn_Scanlon Thanks to all you gurus for never answering the question about not finding the fastcgi module onVista SP1. Though thank you ruslany, without your almost accurate question about a iisfcg.dll file (it should beissfcgi.dll), I never would have worked this out. What the answer to the missing Fast CGI module seems to be (andI'm a novice, but I can display the phpinfo in IE7, and my machine hasn't crashed), is that if you don't have aFastCgiModule available in the "Handler Mappings" dialogue, you need to 1) go into "Modules" dialogue at the sameserver level, 2) Choose the "Configure Native Modules" option on the right pane, 3) Choose "Register" on the nextwindow, and 4) on the following window, insert "FastCgiModule" in the Name textbox and"c:\windows\system32\inetsrv\iisfcgi.dll" in the Path textbox (use the navigate option to protect against your windowsand system directory names being different than mine). Finish configuring this native module, and then the rest ofthe instructions in this otherwise well written article should work.

31. Submitted on Oct 16 2008 byruslany Hi John_Scanlon, sorry for not getting back to you on your question. I am glad you have worked it out. Weare revising this article and I will make sure to include the steps you described about registering FastCGI module.

35. Submitted on Dec 16 2008 bydavid.s Just a note for others that may encounter this problem. IIS7 is apparently not compatible with running PHPapps like WordPress or MediaWiki in wwwroot due to a problem with retrieving path information using functions likerealpath(). They run fine in subdirectories.

36. Submitted on Dec 18 2008 bycoreygo Also this guide suggests using the ZIP package of PHP to install. Because of this when I first set upFastCGI with PHP I ran into this: http://forums.iis.net/t/1149374.aspx. I ran into this page:http://www.thewebhostinghero.com/tutorials/windows2008-iis7-fastcgi-php.html. Which actually noted that a registryentry should be added for PHP: HKEY_LOCAL_MACHINE\SOFTWARE\PHP\IniFilePath = C:\PHP. After I createdthis, I got the Hello World and PHPInfo pages to run correctly.

37. Submitted on Jan 01 2009 byfestuc I will be great to have a guide on how to do:

Use one application pool per web site

Use a dedicated user account as an identity for the application pool

Configure anonymous user identity to use the application pool identity

ruslany david.s IIS7 can run fine with WordPress and MediaWiki in wwwroot. Here is an example: http://ruslany.net.39. Submitted on Jan 09 2009 by

ruslany coreygo. If you look at the phpinfo.php output in this tutorial(http://www.thewebhostinghero.com/tutorials/windows2008-iis7-fastcgi-php.html) you will see that the loaded php.inipath is C:\php\php.ini. This is where the php configuration is loaded from by default when using fastcgi. You canchange this path by using the registry entry, but much less invasive way of changing it is to define an environmentvariable PHPRC for a fastcgi process pool:environmentVariables>environmentVariable name="PHPRC" value="C:\My\Location\To\phpini\" />/environmentVariables>This way the environment variable will be set only for the php-cgi.exe executable.

41. Submitted on Jan 31 2009 byAntG Hi, First, thanks for a really helpful and clear article. With your guidance I have fully installed PHP on IIS and Ihad a working installation with a single php.ini. However I want a per-site configuration. I have three sites on myVista Ultimate/IIS 7.0 machine each with their own root and pool. After some trial and error I think I have theapplicationHost.config file in good shape - with the code that you give for "website1", "website2" etc modified andinside separate location> tags. My outstanding problem is that only one web site works, the other two return 503"Service Unavailable" and I can't see any unintended differences between the one that works and the two that don't.Any ideas please! I have run out.

49. Submitted on Mar 10 2009 byscubak1w1 Hey Ant,

We are having exactly the same problem as you - that is, the PHP only works for one of the sites in II7...

You mentioned that you "just needed to refresh IIS"...

Can you better define "refresh"?

It works like a charm on the one (the first) site, but not the other two I have now set up...

I tried restarting all the relevant services, a server reboot, etc, etc... still the same issue... (although I am getting a404 rather than a 503...)

Thanks in advance - as you say in your original post, "Any ideas please? I have run out!!!!", although I added a fewmore explainaton points! smile>

(note that the directory for the FIRST site is'wwwroot' and the other sites have different names.) *** ASP is working as you would expect - and so I set thehandler mapping for 'PHP via Fast CGI' to have the same Path Type as 'ASP', namely 'File.' *** I am thinking that'PHP via Fast CGI' is somehow erroneously defaulting to the always 'calling' the PHP of the same name in'wwwroot'?? *** Any advice or suggestions would be GREATLY appreciated! *** Cheers" GREG...

Found the issue! Hindsight is a wonderful thing of course, but still "d'oh!!"

I was using a php.ini file, a little adjusted, from the test server on IIS5.1 on an XP box, to help ensure I kept mysettings as I had tweaked them for all my extensions and so forth...

In this 'carry over' php.ini file I had

doc_root = "C:\inetpub\wwwroot"

I just REMed this out, rebooted the server, viola!

Phew! I thought I was going nuts - and have learnt to check my .ini file in *much* great detail! grin>

Onward...

blazingbiz Hi thanks for the write up, I have a few comments:

1. The link for details on the App Pool isolation didn't work but I found this article online:http://www.adopenstatic.com/cs/blogs/ken/archive/2008/01/29/15759.aspx This article seems to suggest a betterway to isolate the App Pools and content of the sites, for those who read this article and can answer this question:"even though the web sites are given read permissions for their respective app pool identities, isn't the fact that theapp pools still run in the Network Service context still allow them to read the files of the other sites?" - please do.

2. I read some comments in the IIS 7 PHP blog about the new improved team work between the PHP team andMicrosoft and they recommend using the windows PHP msi installer that can be used with the Web PI tool and I didthat, what should I be aware of since this is different from the usual way of doing a manual install with the PHP zipfiles, I had it set up that way before but would like to use the Web PI tool going forward.

3. I like the individual php.ini set up outlined towards the end of this article and am setting this up right now on myserver, my concern though is that the php.ini file would be in a web accessible folder online on a live production site,following the examples given here. How would I mitigate this without causing read permission problems on thephp.ini file?

Thanks58. Submitted on Jun 05 2009 by

blazingbiz Also when I set up the individual handler mappings for each site to get the individual site php.ini file I usethe IIS Manager and get an error about entering the exe path and -d arguement within double quotation marks, whenI do it proceeds without error and asks me to if I want to create a FastCGI application for this local mapping, which Ianswered Yes in the dialouge box.

Then I check in the Fast CGI section of the server node and see the new Fast CGI application created, I hadpreveiously created Fast CGI applications for each of the sites I'm doing this for, the difference between them andthe ones created for me via the local site Handler Mapping process is that the new ones have double quotationmarks. I also checked the newly created web.config in my local site and see the Handler Mapping as outlined in theabove article, the php-cgi.exe with the -d arguement. So based on this I have two questions:

1. Can I just manually create the web.config files for each of these local websites and have them point the FastCGIApplications I've already set up without any regard to the double quotation marks or not?

2. The Error Message stated that using a file path with spaces in it, such as the default Program Files/PHP file pathused when installing the php with the windows installer that the Web PI tool uses, would cause an error withoutdouble quotation marks being used. But I set this up with file path under Program Files without quotation marks andit worked fine, why is that?

dvd212 Hello

Im getting this error:

HTTP Error 500.0 - Internal Server ErrorC:\php5\php-cgi.exe - The FastCGI process exited unexpectedly

62. Submitted on Jul 09 2009 bymformigo Hello.

I'm a web developer specialized in php & mysql, on a Windows enviroment with IIS.I used to have XP Pro with IIS 5, with php and mysql working fine.Some time ago i bought a new laptop which came with Vista Home Premium, so i decided to give it a try. I folloedthis tutorial in order to install IIS 7, php 5.2.x and mysql. Everything went fine, aparently, an the ?php phpinfo(); ?>worked ok.

My actual configuration is as follows:Windows Vista Home Premium SP1IIS 7.0 SP1php 5.2.10 ntsmysql 5.1.31

My problem is that IIS began sudently showing a HTTP 500 Internel Server Error.It states as most likely causes the website under maintainance or a programming error.Well, under maintainance naturally doesn't apply, for obvious reasons.And regarding the programming error, i find that very unlikely, because of the following:1st. it doesn't happen when i code something wrong on purpose.2nd. last time this HTTP 500 error occurred was about 2 days ago when i first turned on the laptop to work stillhaving done nothing that day. the curious thing is that the day before, working on that same project, it was renderingthe site just fine just before i shut down the computer.

Sometimes i can get the site to work fine again, but generally i just create a new blank file, copy the content of theoriginal to the new, delete the original and rename the new to the original's name.In other words, I don't change absolutelly nothing in the coding, just replace the file itself and that's it. The problem isthat the site requires many separate files and going around doing this everytime the IIS "gets crazy" like this, it's notvery helpful for the work process.

I've been trying to resolve this situation, but with no sucess until now.I already cleaned and reconfigured php on IIS all over again, just in case.I searched the web for any reference to this problem, but didn't find any other HTTP 500 errors with this simptons.

Sincerelly, i'm running out of ideas....i already thought if this could be some kind of timeout which is preventing the page script from being correctlyprocessed.I also found some topics regarding a certain instability on the use of FastCGI on IIS 7, but again none quitedescribed the simptons i ran across.

An option i'm considering is replacing the fastcgi configuration for the isapi.It may not be so fast, but perhaps can be more stable when dealing with this problem.Another option is to completely replace IIS with Apache (the problema is i tend to prefer IIS so i would rather not

have to come to this).In last case scenario, I can downgrade and return to XP Pro with IIS 5.. but once again i would prefer to solve thisand be able to continue with Vista and IIS 7.

Any help will be deeply apreciated.Thank you all in advance for your time.

Best regards,Michael
