我刚刚创build了简单的.NET核心webapi项目使用https://github.com/omnisharp/generator-aspnet
然后尝试在Ubuntu子系统上运行应用程序。
当我正在运行dotnet start时出现错误：
Unhandled Exception: System.AggregateException: One or more errors occurred. (Error -98 EADDRINUSE address already in use) ---> Microsoft.AspNetCore.Server.Kestrel.Internal.Networking.UvException: Error -98 EADDRINUSE address already in use at Microsoft.AspNetCore.Server.Kestrel.Internal.Networking.Libuv.Check(Int32 statusCode) at Microsoft.AspNetCore.Server.Kestrel.Internal.Networking.UvTcpHandle.GetSockIPEndPoint() at Microsoft.AspNetCore.Server.Kestrel.Internal.Http.TcpListenerPrimary.CreateListenSocket() at Microsoft.AspNetCore.Server.Kestrel.Internal.Http.Listener.<>c.<StartAsync>b__6_0(Object state) --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Microsoft.AspNetCore.Server.Kestrel.Internal.Http.ListenerPrimary.<StartAsync>d__11.MoveNext() --- End of inner exception stack trace --- at System.Threading.Tasks.Task.ThrowIfExceptional(Boolean includeTaskCanceledExceptions) at System.Threading.Tasks.Task.Wait(Int32 millisecondsTimeout, CancellationToken cancellationToken) at Microsoft.AspNetCore.Server.Kestrel.Internal.KestrelEngine.CreateServer(ServerAddress address) at Microsoft.AspNetCore.Server.Kestrel.KestrelServer.Start[TContext](IHttpApplication1 application) at Microsoft.AspNetCore.Hosting.Internal.WebHost.Start() at Microsoft.AspNetCore.Hosting.WebHostExtensions.Run(IWebHost host, CancellationToken token, String shutdownMessage) at Microsoft.AspNetCore.Hosting.WebHostExtensions.Run(IWebHost host) at WebApp.Program.Main(String[] args)
但是，当我在Windows上使用相同的命令运行应用程序在所有的工作就好了。
任何想法如何解决？ WebApi使用端口5000作为默认值。
更新：
我只是使用.UseUrls("http://*:5000")指定内联的默认端口
var host = new WebHostBuilder() .UseConfiguration(config) .UseKestrel() .UseContentRoot(Directory.GetCurrentDirectory()) .UseIISIntegration() .UseStartup<Startup>() .UseUrls("http://*:5000") .Build();
所以现在它工作正常。 但是我没有改变端口值。 任何想法为什么端口5000不工作在Ubuntu时，它没有指定？
