Rails App in Staging 시작 - Unicorn

그래서 Nginx + Unicorn을 실행하는 AWS EC2 인스턴스에 Rails 4 앱을 배포했습니다. 요청이 레일즈 애플리케이션에 영향을 미치기 때문에 모든 것이 유니콘의 끝에서 잘 돌아가고 있다고 생각하지만,이 이상한 500 오류가 발생하고 어디에서 오는지 알 수 없습니다.Rails App in Staging 시작 - Unicorn

다음은 내 staging.log에서 얻은 것입니다. 무슨 일이 일어나고 있는지 전혀 모르겠다. 어떤 도움도 좋을 것이다.

저는 Ruby 전문가입니다. 그러나 오류 로그에서 이와 같은 백 트레이스 덤프는 나에게도 도움이된다. 가장 중요한 몇 줄을 살펴 보는 것이 핵심입니다.

500 오류는 내부 서버 오류가 있음을 의미합니다. PHP, Perl, Ruby 등의 코드에 문제가 있다는 것을 의미합니다. 이는 서버를 완전히 죽이는 것입니다. 그리고 여기에서 볼 수있는 열쇠는 다음과 같습니다.

TypeError (no implicit conversion of Array into String):

배열을 문자열로 지정하려고합니다. 이것이 바로 전체 과정을 죽이는 것입니다. 어디에? 로그를 보지 못했습니다. 하지만 이것이이 모든 일에 실패하는 열쇠입니다. 나머지 덤프는 기본적으로 응용 프로그램을 지원하는 모든로드 된 라이브러리 & 등의 보고서입니다.

분명히 내 코드에 문제가있었습니다. 내 bashrc에서 char가 잘못되어 환경 변수가 제대로 읽히지 않았다. – Cristian

나는 같은 장소에서 비슷한 오류가 발생했습니다 : TypeError (no implicit conversion of Fixnum into String). 사실은 config/secrets.yml에 순전히 숫자로 된 secret_key_base를 설정했기 때문입니다. 아마도 yaml의 해당 속성이 배열로 해석되고 있습니까?

형식은 다음과 같아야합니다 물론

staging: 
    secret_key_base: 61a6fa38260a0fdfecac5c088aadd91e87

, 단지 모든 사람들이 당신의 비밀을 알고 것이며, 그 안전하지 않을 것이기 때문에, 위의 복사/붙여 넣기하지 않습니다.
