레일 앱이 ActiveRecord로 인해 프로덕션 환경에서 시작되지 않음

Question

nginx 및 unicorn을 사용하여 ec2 인스턴스에서 레일즈 앱을 설치하려고 반복적으로 시도했습니다. 나는 nginx와 unicorn이 모두 올바르게 설정되었음을 발견했다. 그러나 두 시스템 모두 내 레일 앱은 프로덕션 환경에서 시작하고 싶지 않습니다. 생산을 시작하려고 시도의 출력은 다음과 같습니다 비록

, 내가 분명히 내 database.yml 파일에서 PostgreSQL의 어댑터를 지정하십시오

# PostgreSQL. Versions 8.2 and up are supported. 
# 
# Install the pg driver: 
# gem install pg 
# On Mac OS X with macports: 
# gem install pg -- --with-pg-config=/opt/local/lib/postgresql84/bin/pg_config 
# On Windows: 
# gem install pg 
#  Choose the win32 build. 
#  Install PostgreSQL and put its /bin directory on your path. 
# 
# Configure Using Gemfile 
# gem 'pg' 
#

정말로 이상한 것은 성공적 모두에서 실행한다는 것입니다 개발 및 테스트 환경. StackOverflow에서 다른 문제를 확인했으며 대부분이 간격 문제라고했습니다. 그러나 동일한 결과로 database.yml 파일을 여러 번 다시 작성했습니다.

내 유니콘 및 nginx 파일은 표준 구성입니다.

도움을 주시면 감사하겠습니다. 이 때까지 나는 서있다. 미리 감사드립니다.

RAILS_ENV RAILS_ENV를 실행

RAILS_ENV=production rails c을 실행하여 레일 콘솔을 사용하여는 생산 :

Rails.env가 생성됩니다

=> "production" 

Answer 1

내 설정이 사용

를

production: 
    adapter: pg 
    encoding: utf8 
    reconnect: false 
    database: my_app_name_production 

Answer 2

database.yml의 어댑터는 postgresql이 아닌 pg 여야합니다.

production: 
    adapter: pg 
    encoding: unicode 
    host: localhost 
    database: study_development 

Answer 3

귀하의 database.yml 설정은 정상입니다. 이상한 건 없어요.

개발 모드가 예외없이 실행되면 문제가 DB에 없습니다.

database.yml을 정확하게 확인하십시오. 아마도 잘못되었거나 사용할 수없는 * 문자 일 수 있습니다.

Answer 4

오류를 포크 (fork)입니다! 일부 캐싱 또는 로그 문제 코드에 오류가 없음을 보여줍니다.

우리 팀이 해결합니다.

• 프로젝트를

• 자식 복제 데이터베이스를 config (설정) 프로젝트

• 을 삭제합니다.YML

• 시작 서버는

다 괜찮습니다!

동일한 프로젝트 오류가 사라졌습니다! 그래서 우리는 그것이 env 문제이거나 cach 또는 log라고 생각합니다.
