.Net основной порт из Windows в Linux

0 голосов
/ 16 ноября 2018

В настоящее время я пытаюсь перенести проект .NET Core, созданный моими коллегами на компьютере с Windows, на виртуальную машину AWS Free Tier на базе Ubuntu. Я выбрал стандартный .NET Core 2.1 предварительно созданный AMI. Установил Apache2 и MySQL 5.7 вместе с phpMyAdmin и обновил все, кроме phpMyAdmin, в котором я сохранил версию репозитория. Я также выбрал именно этот AMI, потому что .NET Core 2.1 - это то, на чем был построен проект на ПК с Windows.

Теперь, когда я запускаю свой проект с:

dotnet Laboratory.Web.dll

Два экземпляра Kestrel запускаются, один на http://0.0.0.0:5000 и другой для SSL на https://0.0.0.0:5001.

Если я оставлю значение по умолчанию app.UseHttpsRedirection(); на Startup.cs и попытаюсь получить доступ к прокси, он перенаправит меня на https://IPOFSERVER:5001, и в консоли ничего не отобразится. Но если я прокомментирую и перекомпилирую проект, в браузере отобразится 500 Internal Server Error, и это будет вывод консоли:

^C^CApplication is shutting down...

Обратите внимание, что apache работает нормально, использую ли я его в качестве прокси-сервера или нет, если я редактирую свой .conf, я могу использовать его для доступа к phpMyAdmin, а если я использую dotnet new mvc и затем запустить Новый проект с dotnet run --urls "http://0.0.0.0:5000" работает нормально, через Apache.
