部署時Azure PHP Webrole隨機錯誤500

Question

我遇到過azure php webrole部署的奇怪行為，當我瀏覽頁面時每秒顯示錯誤500錯誤時都會發生奇怪的行為，但是如果我再次發布但未做任何更改，但我嘗試在事件查看器中找到某些內容沒什么

， 有什么建議么？

一些調試信息：發生該錯誤時，我使用遠程桌面檢查了IIS配置，我注意到PHP處理程序指定了錯誤的路徑，例如F：\\ wwwroot \\ bin \\ php \\ php-cgi.exe，但在服務器上的真實路徑為E： \\ wwwroot \\ bin \\ php \\ php-cgi.exe我認為驅動器號（F :)從我發布BUT的系統中傳來，因為我說奇怪的是，它一次可以工作，但是當我再次發布它時，錯誤發生...

setup_web.cmd（我已經從https://azure.microsoft.com/zh-cn/documentation/articles/cloud-services-php-create-web-role/復制了它）

@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

更新：解決此問題后，我認為問題出在以下地方：我第一次發布Azure時，我的項目文件夾位於E：\\驅動器上，當Azure創建E：\\驅動器並使用cmdlet設置php處理程序路徑時，但是當我再次發布Azure刪除時驅動器E：\\，並創建驅動器F：\\，並嘗試再次配置IIS，但它拋出以下錯誤：

所以我想它不能設置php的配置，因為它已經設置了，因此會引發重復的錯誤

因此，我需要這樣的事情：要么使驅動器號在發布時不發生更改，要么使用以下方案更改配置腳本：首先刪除現有的IIS配置，以避免重復的錯誤，然后再次添加。

Answer 1

您必須刪除配置中的前一個PHP路徑，然后設置新路徑，例如，必須放置以下行：

%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

Answer 2

在maxmayer建議之后，我更正了setup_script

腳本的完整工作副本：

@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 /-"[maxInstances='12',idleTimeout='60000',activityTimeout='3600',requestTimeout='60000',instanceMaxRequests='10000',protocol='NamedPipe',flushNamedPipe='False']" /commit:apphost
%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
