部署时出现Azure php webrole随机错误500

我曾经体验过azure php webrole部署的奇怪行为，当我浏览页面时，每一秒部署都会显示error 500 error，但如果我再次发布，并且没有任何更改，那么我会尝试在事件查看器中查找一些内容，但什么都没有

，有什么建议吗

一些调试信息： 当那个错误发生时，我使用远程桌面检查了IIS配置，我注意到PHP处理程序指定了错误的路径，例如F:\wwwroot\bin\PHP\PHP-cgi.exe，但在服务器上，实际路径是E:\wwwroot\bin\PHP\PHP-cgi.exe，我想驱动器号（F:）是从我发布的系统中跟随的 但是，正如我所说，奇怪的是，有一次它可以工作，但当我再次发布它时，错误就发生了

setup_web.cmd（我从中复制了它）

更新： 在解决了这个问题后，我认为问题如下： 当我第一次发布azure创建E:\drive并使用cmdlet设置php处理程序路径时，我的项目文件夹位于E:\drive上，但当我再次发布时，azure会删除驱动器E:\并创建驱动器F:\并再次尝试混淆IIS，但会引发以下错误：

F:\approot\bin>cd "F:\approot\bin\" 

F:\approot\bin>if "false" == "true" exit /b 0

所以我猜它不能设置php的配置，因为它已经设置好了，因此会抛出重复的错误

---

所以我需要这样的东西：要么使驱动器号在发布时不发生更改，要么使用以下场景更改配置脚本：首先删除现有IIS配置以避免重复错误，然后再次添加它。

您必须删除配置中以前的PHP路径，然后设置新路径，例如，你必须写这行：

%WINDIR%\system32\inetsrv\appcmd.exe set config -section:system.webServer/handlers /-"[name='PHP']" /commit:apphost

之前：

%WINDIR%\system32\inetsrv\appcmd.exe set config -section:system.webServer/handlers /+"[name='PHP',path='*.php',verb='GET,HEAD,POST,OPTIONS',modules='FastCgiModule',scriptProcessor='%PHP_FULL_PATH%',resourceType='Either',requireAccess='Script']" /commit:apphost

---

根据maxmayer的建议，我更正了设置脚本

脚本的完整工作副本：

@ECHO ON

if "%EMULATED%"=="true" exit /b 0

msiexec /i sqlncli.msi /qn IACCEPTSQLNCLILICENSETERMS=YES

SET NEW_PATH=%PATH%;%RoleRoot%\base\x86

云服务中使用的PHP版本是什么？根据你的另一个问题，这个问题是否发生在laracel应用程序中？您使用哪种版本的laravel？由于在我这边重现这个问题有点困难。是的，它发生在Laravel应用程序中，我使用的是PHP5.6，我注意到的一点是，当我发布软件包并出现错误时，IIS配置中的php处理程序指定了错误的路径我正在使用powershell命令从windows 10发布我在说明中添加了一些调试信息，如果没有答案，请向上投票问题..感谢您帮助我编写完整的安装脚本，所以我接受你的答案，我将用工作设置脚本更新我的问题。
