【问题描述】：

我最近使用 angular asp.net-core 和 SQLserver 完成了我的约会应用项目，我尝试将项目发布到 IIS。

当我在本地运行项目时，所有请求都会得到所需的响应，并且工作正常，但是当我从 IIS 服务器打开网站时，应用程序工作正常，但任何请求都会返回 500 代码响应。 在我的 web.config 文件中将 stdoutLogEnabled 设置为“true”后，我发现有多个错误：

fail: Microsoft.EntityFrameworkCore.Database.Command[20102]

      Failed executing DbCommand (11ms) [Parameters=[], CommandType='Text', CommandTimeout='60']

      CREATE DATABASE [Datingapp];

似乎所有错误都绑定到 ef 并且它无法连接到 sqlserver（如果重要的话，身份验证是基于 Windows 的......），正如我所说的，它在本地工作正常。

web.config：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location path="." inheritInChildApplications="false">
    <system.webServer>
      <handlers>
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
      </handlers>
      <aspNetCore processPath="dotnet" arguments=".\DatingApp.API.dll" stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout" hostingModel="inprocess" />
    </system.webServer>
  </location>
</configuration>

.NET 托管 IIS 已安装并且是最新的。

有什么想法吗？

【问题讨论】：

您的用户“IIS APPPOOL\约会应用”。无法登录并连接到数据库。所以设置它的凭据可以访问。

感谢您的快速响应，您能指导我如何配置该用户凭据吗？@abestrad

@IgalAchourov 你在服务器上有命令行（或 PowerShell）访问权限吗？ osql Utility; SQL-Server - Grant user DBO permission on database。为了安全起见，您可能希望之后将权限设置回“正常”。

【参考方案1】：

连接字符串指向错误的数据库或用于连接数据库的应用程序池标识没有足够的权限访问数据库。

尝试将应用程序池身份设置为具有访问 SQL Server 数据库（管理员用户）的完全权限的自定义帐户。

给他们一个服务器角色，它将给他们创建数据库的凭据。设置 db_owner 和 public。

更多详情请参考以下链接：

CREATE DATABASE permission denied in database 'master' (EF code-first)

【讨论】：

我虽然错误来自 Windows 身份验证，但我现在尝试通过我创建的具有所有权限的用户连接到数据库，但没有成功。连接字符串很好，因为它在本地工作，也许在 web.config 文件中我需要指定路径？（web.config 文件显示在帖子中）。

【参考方案2】：

感谢大家帮助解决问题，这是我第一次使用 IIS 进行发布，问题出在应用程序池标识中，如您所说，但也出现在需要指定“物理路径凭据”的站点中。

【讨论】：

如果您的问题得到解决，我请求您将有用的建议标记为答案，它将帮助面临类似问题的其他人。
