如何修复错误“ANCM In-Process Handler Load Failure"?

问题描述

我正在 Windows Server 2016 Standard 上的 IIS 中设置第一个站点.这是一个 NET Core 2.2 应用程序.我无法显示该网站.

I'm setting up the first site in IIS on Windows Server 2016 Standard.This is a NET Core 2.2 application. I cannot get the site to show.

我收到此错误:

HTTP 错误 500.0 - ANCM 进程内处理程序加载失败

我可以更改什么来清除此错误并显示我的网站?

What can I change to clear this error and get my site to display?

我的应用程序是一个 dll.

My application is a dll.

我通过命令提示符在服务器上测试了我的应用程序

I tested my application on the server through the Command Prompt with

dotnet ./MyApp.dll

它显示在浏览器中，但只显示在服务器上，带有 (localhost:5001/).

it displays in the browser but only on the server itself with (localhost:5001/).

使用此方法无法从任何其他服务器访问该站点.当我通过 IIS 设置站点时，我在服务器和尝试访问该站点的服务器上都收到了 In-Process 错误.

Using this method the site cannot be accessed from any other server.When I set up the site through IIS, I get the In-Process error both on the server and from servers attempting to access the site.

起初我收到了 Out-Process 错误.我读到的东西说要将此(hostingModel =inprocess")添加到我的 web.config所以我做了，但现在我收到了处理中错误.

At first I was receiving the Out-Process error. Something I read said to add this (hostingModel="inprocess") to my web.configso I did but now I receive the In-Process error.

该站点安装在我的开发服务器上后运行良好.

The site works fine when installed on my development server.

IIS AspNetCore 模块 V2"的事件查看器显示此错误:

The Event Viewer shows this error for "IIS AspNetCore Module V2":

无法启动应用程序/LM/W3SVC/2/ROOT"，错误代码0x8000ffff".

这是我的web.config:

<?xml version="1.0" encoding="utf-8"?>
    <configuration>
  <system.web>
    <customErrors mode="RemoteOnly"></customErrors>
        <identity impersonate="false" password="****" userName="****" />
  </system.web>
  <system.webServer>
    <handlers>
      <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
    </handlers>
    <aspNetCore processPath="dotnet" arguments=".MyApp.dll" stdoutLogEnabled="false" hostingModel="inprocess" stdoutLogFile=".logsstdout" forwardWindowsAuthToken="false">
      <environmentVariables />
    </aspNetCore>
  </system.webServer>
</configuration>

推荐答案

我在 .Net core 2.2 中遇到了同样的问题.当我更换

I had the same issue in .Net core 2.2. When I replace

web.config:

<handlers>
    <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
</handlers>

到

<handlers>
    <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" />
</handlers>

然后它工作正常.

注意:同样的解决方案也适用于 .Net core 2.2 和其他更高版本.

Note: The same solution also works for .Net core 2.2 and other upper versions as well.
