在 CentOS 7 上使用 Letsencrypt 的 Net Core 2.2

Question

我正在尝试在我的 asp.net core 2.2 中使用letsencrypt证书 Letencrypt 证书已安装并正常工作..（SSL 实验室测试）

== 抛出异常 ==

[FTL] Unable to start Kestrel. Interop+Crypto+OpenSslCryptographicException: error:2006D002:BIO routines:BIO_new_file:system lib at Interop.Crypto.CheckValidOpenSslHandle(SafeHandle handle) at Internal.Cryptography.Pal.CertificatePal.FromFile(String fileName, SafePasswordHandle password, X509KeyStorageFlags keyStorageFlags) at System.Security.Cryptography.X509Certificates.X509Certificate..ctor(String fileName, String password, X509KeyStorageFlags keyStorageFlags) at System.Security.Cryptography.X509Certificates.X509Certificate2..ctor(String fileName, String password) at Microsoft.AspNetCore.Server.Kestrel.KestrelConfigurationLoader.LoadCertificate(CertificateConfig certInfo, String endpointName) at Microsoft.AspNetCore.Server.Kestrel.KestrelConfigurationLoader.Load() at Microsoft.AspNetCore.Server.Kestrel.Core.KestrelServer.ValidateOptions() at Microsoft.AspNetCore.Server.Kestrel.Core.KestrelServer.StartAsync[TContext](IHttpApplication`1 application, CancellationToken cancellationToken)

我的 appsettings.json

...
,
  "Kestrel": {
    "EndPoints": {
      "Http": {
        "Url": "http://localhost:5000"
      },
      "HttpsInlineCertFile": {
        "Url": "https://localhost:5001",
        "Certificate": {
          "Path": "/etc/myletsencrypt/cert.pfx"  // ==> this is converted from .pem to pfx
        }
      }
    }
  }

== 程序.cs==

public static void Main(string[] args)
        {
            CreateWebHostBuilder(args).Build().Run();
        }

        public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
        WebHost.CreateDefaultBuilder(args)

        .UseStartup<Startup>()   
        .UseUrls("http://0.0.0.0:5000","https://0.0.0.0:5001");

== 启动.cs ==

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory) { loggerFactory.AddSerilog();

        // linux setting
        app.UseForwardedHeaders(new ForwardedHeadersOptions
        {
            ForwardedHeaders = ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto
        });

        app.UseAuthentication();
        app.UseHttpsRedirection();

        app.UseMvc(routes =>
        {
            routes.MapRoute(
                name: "default",
                template: "{api}/{controller}/{action}");
        });

}

}

我错过了什么？ 有没有人有过这方面的经验？

需要建议

提前非常感谢 唐

Answer 1

最后，我通过在 apache 中设置反向代理解决了这个问题：

我只使用端口 5000 并为 /api/ 设置 proxypass 所以如果用户访问https://dev.myexample.com/api/xxxx，那么它会转到http://localhost:5000/api/xxxx 我觉得挺好的，不用我做NAT 5000端口

如果有更好的想法请告诉我

感谢和问候 唐
