IIS 和 NET Core HTTP 错误 500.30 - ANCM 进程内启动失败 .net core 3.1

Question

我已经从模板在 .NET Core 中创建了应用程序 - 使用 Angular 和身份验证。 .NET 核心 3.1 在属性->调试-> IIS 配置文件中，我将托管模型设置为进程外。但在 Web.config 中，我仍然在处理中。 我已经从这个站点安装了 ASP Core Runtime：https://dotnet.microsoft.com/download/dotnet/current 当我以 IIS Express 运行我的项目时，它可以工作。 但是当我将已发布的文件复制到 IIS 文件夹时出现错误：

HTTP Error 500.30 - ANCM In-Process Start Failure
Common solutions to this issue:
The application failed to start
The application started but then stopped
The application started but threw an exception during startup
Troubleshooting steps:
Check the system event log for error messages
Enable logging the application process' stdout messages
Attach a debugger to the application process and inspect

我已经尝试了许多来自互联网的解决方案，因为错误是众所周知的，但没有结果。

我已将 InProcess 更改为 OutOfProcess，现在我的配置如下所示：

<system.webServer>
    <handlers>
      <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
    </handlers>
    <aspNetCore processPath="dotnet" arguments=".\WebApplication2.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="OutOfProcess" />
  </system.webServer>

我得到错误：

An error occurred while starting the application.

Answer 1

整整一天后，我找到了一个很好的解决方案，请注意以下几点：-

1. 通过 cmd 进入您的项目文件夹。
2. type dotnet publish --e/:output（注意这会在e盘输出中发布代码 文件夹）
3. 通过 cmd 进入输出文件夹
4. 键入 dotnet （这将在 localhost:5003 中运行应用程序）
5. 如果上述步骤出现任何问题，这将显示在 cmd 中，我曾遇到过以下问题， 缺少一个文件夹的地方。添加文件夹后，问题就解决了。

Answer 2

您可以在 ASP.NET Core 应用程序文件夹中编辑您的 web.config。默认情况下，它位于wwwroot 文件夹内。

将AspNetCoreHostingModel 或hostingModel 的值更改为OutOfProcess。

<?xml version="1.0" encoding="utf-8"?> 
<configuration> 
  <location path="." inheritInChildApplications="false"> 
    <system.webServer>
      <handlers> 
        <add name="aspNetCore" path="" verb="" modules="AspNetCoreModule" resourceType="Unspecified" /> 
      </handlers> 
      <aspNetCore processPath=".\fad.exe" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="OutOfProcess" /> 
    </system.webServer> 
  </location> 
</configuration>

Answer 3

您是否注意到您的发布配置文件显示为

所以请到你项目的根目录，用记事本打开.csproj。

然后修改<AspNetCoreHostingModel>InProcess</AspNetCoreHostingModel>

到

<AspNetCoreHostingModel>OutOfProcess</AspNetCoreHostingModel>

并重新发布。

或者您可以尝试将发布配置文件从<MSDeployPublishMethod>InProcess</MSDeployPublishMethod> 修改为<MSDeployPublishMethod>OutofProcess</MSDeployPublishMethod> 然后修改

hostingModel="inprocess" 到 hostingModel="OutOfProcess" 从 IIS web.config 中的 asp.net 核心处理程序。
