使用 .NET core 3 / 3.1 的 Linux CentOS 8 中没有显示日志

Question

我很想提供错误消息，但这就是我得到的全部......

我错过了什么吗？ .NET core 3.1 与 2.1/2.2 中的 Linux 部署有什么额外变化吗？

我尝试尽快退出...

程序.cs

public class Program
    {
        public static void Main(string[] args)
        {
            bool dev = Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT") == "Development";
            var logPath = dev ? "/Logs/gweb_log.txt" : "/var/log/gweb/gweb.log";

            Log.Logger = new LoggerConfiguration()
                .MinimumLevel.Debug()
                //.MinimumLevel.Override("Microsoft", LogEventLevel.Information)
                .Enrich.FromLogContext()
                //.WriteTo.AzureApp()
                .WriteTo.File(logPath, rollingInterval: RollingInterval.Day, fileSizeLimitBytes: 10485760, rollOnFileSizeLimit: true, retainedFileCountLimit: 3)
                .CreateLogger();

            try
            {
                Log.Information($"Garos_Web Started Utc: {DateTime.UtcNow}!");
                CreateHostBuilder(args).Build().Run();
            }

            catch (Exception e)
            {
                Log.Error($"Something went wrong. UTC: {DateTime.UtcNow}");
                Log.Error(e.Message);
                if (e.InnerException != null && !string.IsNullOrEmpty(e.InnerException.Message))
                {
                    Log.Error(e.InnerException.Message);
                }

                Log.Error(e.StackTrace);
            }
            finally
            {
                Log.CloseAndFlush();
            }

        }

        public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .ConfigureWebHostDefaults(webBuilder =>
                {
                    webBuilder.UseSerilog()
                    .UseStartup<Startup>()
                    .UseKestrel(options =>
                    {
                        options.Listen(System.Net.IPAddress.Loopback, 5000);
                    });
                }
            );
    }

确保添加签名证书是新的，但我认为框架的一个很好的要求......

如何将.WriteTo.Console() 添加到该 serilog 设置中？您还需要在相关的 csproj 文件中包含此包：https://www.nuget.org/packages/serilog.sinks.console/
