У меня проблемы с развертыванием моих собственных shiny приложений на сервере AWS.Я следовал этим инструкциям до тройника.Я смог установить shiny и увидеть примеры приложений, работающих на моем сервере.Однако, когда я пытаюсь запустить свое собственное приложение, я вижу сообщения об ошибках:
"Произошла ошибка
Не удалось запустить приложение.
Приложение завершилось во время инициализации. "
Согласно многим форумам, например этот , мне нужно изменить разрешения в файле /etc/shiny-server/shiny-server.conf с run_as shiny; до run_as myusername shiny.Я попробовал это, но это не сработало.
Мой журнал выглядит так:
cat /var/log/shiny-server.log

Также, когда я набираю shiny-server, я вижу:
Using config file "/etc/shiny-server/shiny-server.conf"

Любая помощь будет принята с благодарностью.Мне кажется, что я так близок к тому, чтобы наконец запустить свое приложение!
