nginxとunicornを使用してec2インスタンスでRailsアプリをセットアップしようと繰り返し試みました。nginxとunicornの両方が適切に設定されていることがわかりました。ただし、両方のマシンで、私のRailsアプリは本番環境で起動したくありません。本番環境で起動しようとした場合の出力は次のとおりです。

ただし、database.ymlファイルでpostgresqlアダプターを明確に指定しています。
# 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'
#
development:
adapter: postgresql
encoding: unicode
host: localhost
database: study_development
pool: 5
# Connect on a TCP socket. Omitted by default since the client uses a
# domain socket that doesn't need configuration. Windows does not have
# domain sockets, so uncomment these lines.
#host: localhost
#port: 5432
# Schema search path. The server defaults to $user,public
#schema_search_path: myapp,sharedapp,public
# Minimum log levels, in increasing order:
# debug5, debug4, debug3, debug2, debug1,
# log, notice, warning, error, fatal, and panic
# The server defaults to notice.
#min_messages: warning
# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
adapter: postgresql
encoding: unicode
host: localhost
database: study_test
pool: 5
production:
adapter: postgresql
encoding: unicode
host: localhost
database: study_production
pool: 5
本当に奇妙なのは、開発環境とテスト環境の両方で正常に実行されることです。StackOverflowで他の問題を確認しましたが、ほとんどの場合、これは間隔の問題であると言われています。database.ymlただし、ファイルを数回やり直したところ、同じ結果になりました。
私のユニコーンとnginxファイルは標準構成です。
どんな援助でも大歓迎です。これが実行されるまで、私は静止しています。前もって感謝します。
RAILS_ENV
Rails Consoleを実行して使用する場合RAILS_ENV=production rails c、を実行すると次のようになりRAILS_ENVます。
