azure - 角色遇到错误并已停止

Question

我面临的问题与我们在 this 中遇到的问题非常相似问题。

我们有一个标准的 MVC5 应用程序，我们已使用 webrole 将其部署在 Windows Azure 上。

部署后，我可以在 Visual Studio 的“Microsoft Azure 事件日志”窗口中看到以下错误消息

Your role instances have recycled a number of times during an update or upgrade operation. This indicates that the new version of your service or the configuration settings you provided when configuring the service prevent the role instances from running. Verify your code does not throw unhandled exceptions and that your configuration settings are correct and then start another update or upgrade operation.

我可以在管理控制台上看到以下错误消息。

Restarting (Role has encountered an error and has stopped. Sites were deployed. [2014-10-22T04:46:57Z])

我在事件查看器中发现以下错误消息。 (虚拟机内部)

 The description for Event ID 1007 from source Windows Azure Runtime 2.4.0.0 cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event: 

    2232
    WaIISHost
    Role entrypoint could not be created: System.TypeLoadException: Unable to load the role entry point due to the following exceptions:
    -- System.IO.FileLoadException: Could not load file or assembly 'System.Web.Mvc, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

我不知道为什么它指的是版本4.0.0.0我的 web.config 文件部分如下所示。

 <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">

Answer 1

您的 web.config 控制 w3wp.exe，但您的调用堆栈表明您在 WaIISHost.exe 中崩溃。您有几个选择:

1. 为什么要在角色入口点 DLL(通常是 WebRole.cs)中引用 System.Web.Mvc？如果您可以重构这部分代码，那么您就不必担心在 WaIISHost 进程中加载​​此 DLL 及其所有依赖项。
2. 使用与 web.config 中相同的绑定(bind)重定向创建 app.config。
