Fixing integration issues of manually installed WordPress, MySQL, Php using IIS on Windows Servers

Error#1:

Your PHP installation appears to be missing the MySQL extension which is required by WordPress.

Fix: Enable MySQL Extension for Php via php.ini as shown below:

;;;;;;;;;;;;;;;;;;;;;;
; Dynamic Extensions ;
;;;;;;;;;;;;;;;;;;;;;;

; If you wish to have an extension loaded automatically, use the following
; syntax:
;
;   extension=modulename.extension
;
; For example, on Windows:
;
;   extension=msql.dll
;
; … or under UNIX:
;
;   extension=msql.so
;
; … or with a path:
;
;   extension=/path/to/extension/msql.so
;
; If you only provide the name of the extension, PHP will look for it in its
; default extension directory.
;
; Windows Extensions
; Note that ODBC support is built in, so no dll is needed for it.
; Note that many DLL files are located in the extensions/ (PHP 4) ext/ (PHP 5)
; extension folders as well as the separate PECL DLL download (PHP 5).
; Be sure to appropriately set the extension_dir directive.
;

extension=php_mysql.dll

and also add up below locations to:

;;;;;;;;;;;;;;;;;;
; Fopen wrappers ;
;;;;;;;;;;;;;;;;;;

extension_dir = “C:\php55\ext\”
error_log = “C:\windows\Temp\php-5.5.12_errors.log”
upload_tmp_dir = “C:\windows\Temp\”
cgi.force_redirect = 0
cgi.fix_pathinfo = 1
fastcgi.impersonate = 1
fastcgi.logging = 0

Troubleshooting: Install Php Manager for IIS to see what’s going wrong with your Php.ini

Verify the FastCGI settings at Server level that gets inherits to the web sites

Fix:

Delete the Web.Config from your Web site root and Restart IIS to recreate it afresh. Ensure it has the Handler and Default document config entered as shown below

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <handlers>
            <add name="PhpWin55" path="*.php" verb="*" modules="FastCgiModule" scriptProcessor="C:\php55\php-cgi.exe" resourceType="Either" requireAccess="Script" />
        </handlers>
        <directoryBrowse enabled="false" />
        <defaultDocument>
            <files>
                <clear />
                <add value="index.php" />
                <add value="Default.htm" />
                <add value="Default.asp" />
                <add value="index.htm" />
                <add value="index.html" />
                <add value="iisstart.htm" />
                <add value="default.aspx" />
            </files>
        </defaultDocument>
    </system.webServer>
</configuration>
