具有身份的应用程序在 Ubuntu 服务器 20.04LTS 上启动时崩溃

问题描述

在服务器上部署我的 MVC Web 应用程序时，应用程序崩溃。 它在我的本地 Visual Studio 上运行良好，但在我的 Ubuntu 20.04 LTS 上启动时崩溃。

错误是它在我添加身份模块之前启动时没有启动...... 须藤 systemctl 停止 myapp.service

● myapp .service - myapp app
 Loaded: loaded (/etc/systemd/system/myapp .service; enabled; vendor preset: enabled)
 Active: activating (auto-restart) (Result: exit-code) since Mon 2021-01-11 11:54:21 UTC; 4s ago
Process: 17943 ExecStart=/usr/bin/dotnet /var/www/myapp .be/net5.0/myapp .be.dll (code=exited,status=1/FAILURE)

主 PID：17943（代码=退出，状态=1/失败）

我怀疑身份管理器崩溃了。虽然它在我的 Visual Studio Windows 开发环境中托管时运行良好 最烦人的是它没有崩溃它甚至没有启动显示没有错误...

我的 startup.cs 文件。

                app.UseHsts();
            }
            app.UseHttpsRedirection();
            app.UseStaticFiles();

            app.UseRouting();

            app.UseAuthentication();
            app.UseAuthorization();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllerRoute(
                    name: "default",pattern: "{controller=Home}/{action=Index}/{id?}");
                endpoints.MapRazorPages();
            });

 
        }
    }
}

更新 1： 仍在调查，但我从我在 github 等上看到的内容来看......在 Linux 上身份可能会被破坏......所以我切换到 Windows 服务器，一切正常......

解决方法

您可以在终端中使用以下命令运行您的项目

dotnet run

如果您的项目已发布，您可以在终端中使用以下命令

dotnet YourProject.dll

我认为您可以在 Linux 服务器中为您的 .net 核心项目使用 Nginx 反向代理

server {
    listen        80;
    server_name   example.com *.example.com;
    location / {
        proxy_pass         http://localhost:5000;
        proxy_http_version 1.1;
        proxy_set_header   Upgrade $http_upgrade;
        proxy_set_header   Connection keep-alive;
        proxy_set_header   Host $host;
        proxy_cache_bypass $http_upgrade;
        proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Proto $scheme;
    }
}
