Windows Azure SQL Database Marketplace
One of our goals for MIX was to give our developers more flexibility while ensuring they still benefit from the unique time-saving deployment, monitoring, and management features of Windows Azure. One way in which we went about this was to enable IIS FastCGI module in the Web role. This module enables developers to deploy and run applications written with 3rd party programming languages such as PHP.
1) As with the .NET full trust example, the first step is to set the enableNativeCodeExecution attribute to true in your Service Definition file:
<?xml version="1.0" encoding="utf-8"?>
<ServiceDefinition name="MyService" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceDefinition">
<WebRole name="WebRole" enableNativeCodeExecution="true">
<InputEndpoint name="HttpIn" protocol="http" port="80" />
2) Install the following required fix for FastCGI in the Windows Azure Development Fabric: http://support.microsoft.com/kb/967131.
3) To enable FastCGI, include a Web.roleconfig file in the root of your project, telling us which FastCGI application you will be using. For example, for PHP:
<?xml version="1.0" encoding="utf-8" ?>
<application fullPath="%RoleRoot%\php\php-cgi.exe" />
Note: The FastCGI application must be xcopy-deployable and contained in your project. In this case, it is in the “php” subdirectory and specified via the special %RoleRoot% environment variable. An xcopy-deployable version of PHP for Windows can be downloaded from http://php.net.
4) Finally, modify your Web.config to configure your handlers. This tells us which paths (e.g. *.php) map to the FastCGI application:
<add name="PHP via FastCGI"
Now, you should be able to invoke your FastCGI application. Here is an example of a multi-instance PHP-based application that has been one-click deployed to the Development Fabric (a simulation of the cloud environment). It has been configured to use three Web role instances via a simple modification to the Service Configuration file:
