Я новичок в развертывании, у меня есть приложение rails с Ruby 2.4.1 и rails v 5.1.Я использовал развертывание mina с единорогом в качестве сервера приложений, а nginx - веб-сервер.Я развернул приложение, используя инструмент развертывания mina, и он показывает, что результаты успешны.Я проверил свои логи в единороге, в nginx, ошибки не найдено.я обновил mina и nginx.conf, основываясь на разных уроках, это не дает результата.Также nginx работает хорошо.Я использовал gcloud для провайдера развертывания.
