尝试在 IIS 中启动我的 asp.net 应用程序池时出现部署问题答案

【问题标题】：Deployment issue when attempting to start my asp.net app pool in IIS尝试在 IIS 中启动我的 asp.net 应用程序池时出现部署问题

【问题描述】：

我的 ASP.NET C# 网站在部署到 IIS 时没有启动。我按照此页面上的步骤操作：

https://www.c-sharpcorner.com/article/access-website-hosted-on-iis/

我也尝试将我的应用程序部署为应用程序。我遇到的问题是应用程序池最终停止，并且在重新启动应用程序池 + iis 重置时尝试浏览它时出现错误

无法访问此网站

部署为网站时错误代码为 ERR_CONNECTION_REFUSED。

当部署为 Web 应用程序时，我收到以下堆栈跟踪错误。

我在我的应用程序池高级设置中启用了 32 位应用程序，因为这是一个 x86 编译的网络应用程序。它与在连接设置中配置为 localhost 的数据库相关联。

当通过 Visual Studio 运行我的网站时，它运行良好，包括数据库连接。

使用与部署我的 asp.net 应用程序相同的步骤部署一个简单的 HTML 应用程序时，网络会立即启动，甚至可以被外界看到（因此不是防火墙/iis 问题）。

在事件查看器中研究此问题时，应用程序事件日志似乎显示了我的实际问题。这似乎是我需要解决的问题。我希望能深入了解如何解决此问题：

就像我说的，过了一会儿，应用程序池由于故障而停止，网络完全离线。

非常感谢任何帮助。谢谢。

想通了...这是我的数据库连接。我将它设置为使用 win auth，但我的系统用户的安全性没有被授予访问权限。我决定只添加一个 Web 用户帐户来访问数据库并使用 sql auth，然后错误就消失了。我的网站现已上线。
