我已经经历了蔚蓝的PHP webrole部署的奇怪行为，在每一秒部署时，我眉头页它显示错误500错误，但如果我没有任何变化再次发布比它的作品，我已经尝试找到在事件查看器的东西，但没有什么Azure的PHP webrole随机误差500
，有什么建议？
一些调试信息： 当发生错误时，我使用远程桌面检查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但在服务器上真正的路径是E：\ wwwroot \ bin \ php \ php-cgi.exe我认为从我的系统发布 的驱动器号（F :)跟着我说奇怪的是有一次它工作但当我再次发布它比错误发生...
setup_web.cmd（我从https://azure.microsoft.com/en-us/documentation/articles/cloud-services-php-create-web-role/复制它）

UPDATE： 解决此问题的工作后，我觉得问题是以下几点： 我第E我的项目文件夹：\驱动器，当我发布首次蔚蓝创建E：\驱动器和使用的cmdlet设置PHP处理路径，但是当我发布再次蔚蓝删除驱动器E：\和创建驱动器F：\并尝试confugre IIS再次略高于它抛出以下错误：

所以我想它可以\'吨设置PHP的配置，因为它已经被设置因此引发重复错误
所以我需要的东西是这样的：要么使这样盘符不会更改在发布或使用followi更改配置脚本ng方案：首先删除现有的IIS配置，以避免重复的错误并重新添加。
云服务中使用的是什么PHP版本？并根据你的另一个问题http://stackoverflow.com/questions/35357846/change-document-root-on-azure-php-webrole，剂量这个问题发生在laracel应用程序？你使用哪个版本的laravel？因为在我这边重现这个问题有点困难。 –
是的，它发生在Laravel应用，我在使用PHP 5.6 – Phoebus
我注意到的一件事是，当我发布包和错误发生在IIS配置已经走错了路指定 – Phoebus
