php - Azure php webrole 部署时出现随机错误 500

Question

我遇到了 azure php webrole 部署的奇怪行为，当我浏览页面时，每秒都会显示错误 500 错误，但是如果我再次发布而不进行任何更改，那么我会尝试在事件中找到一些内容查看器，但什么也没有

，有什么建议吗？

一些调试信息:发生该错误时，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 但在服务器上的实际路径是 E:\wwwroot\bin\php\php-cgi.exe 我认为驱动器号 (F:) 是从我发布的系统开始的但是，正如我所说，奇怪的是，有一次它有效，但当我再次发布它时，错误发生了......

setup_web.cmd(我是从 https://azure.microsoft.com/en-us/documentation/articles/cloud-services-php-create-web-role/ 复制的)

@ECHO ON
cd "%~dp0"

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

msiexec /i sqlncli.msi /qn IACCEPTSQLNCLILICENSETERMS=YES

SET PHP_FULL_PATH=%~dp0php\php-cgi.exe
SET NEW_PATH=%PATH%;%RoleRoot%\base\x86

%WINDIR%\system32\inetsrv\appcmd.exe set config -section:system.webServer/fastCgi /+"[fullPath='%PHP_FULL_PATH%',maxInstances='12',idleTimeout='60000',activityTimeout='3600',requestTimeout='60000',instanceMaxRequests='10000',protocol='NamedPipe',flushNamedPipe='False']" /commit:apphost

%windir%\system32\inetsrv\appcmd.exe set config /section:urlCompression /doDynamicCompression:True /commit:apphost
%windir%\system32\inetsrv\appcmd.exe set config  -section:system.webServer/httpCompression /+"dynamicTypes.[mimeType='application/json; charset=utf-8',enabled='True']" /commit:apphost
%WINDIR%\system32\inetsrv\appcmd.exe set config -section:system.webServer/fastCgi /"[fullPath='%PHP_FULL_PATH%'].queueLength:50000"

更新:解决这个问题后，我认为问题如下:我的项目文件夹位于 E:\驱动器上，当我第一次发布时，azure 创建 E:\驱动器并使用 cmdlet 设置 php 处理程序路径，但是当我再次发布时，azure 会删除驱动器 E:\并创建驱动器 F:\并尝试再次配置 IIS，它会抛出以下错误:

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

所以我猜它无法设置 php 的配置，因为它已经设置，因此会抛出重复的错误

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

您必须删除配置中以前的 PHP 路径，然后设置新的路径，例如，您必须添加这一行:

%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
