Carrierwave で Fog を使用しようとしていますが、Unicorn ログにこのエラーが記録されています。gemfile と NodeImageUploader 呼び出しに霧があります

することbundle show fogは私に与えます /home/deployer/apps/allotrop/shared/bundle/ruby/1.9.1/gems/fog-1.3.1

また、本番環境のレーキ タスクで Carrierwave のremote_image_url方法を使用して、画像を S3 に正常に保存できます。しかし、アプリのページを取得しようとすると、このエラーが発生します。

アップローダを に切り替えると、開発storage :fileで使用する場合でも、アプリケーションは正常に動作しstorage :fogます。どこが間違っていますか？

1 日の大半でこの問題を修正しようとした後、ゼロ ダウンタイム デプロイに関する Ryan Bates の Railscasts エピソードの手順に従って修正しました。彼が言及した変更はpreload_app、ユニコーン テンプレートを追加し、ユニコーンの再起動に USR2 シグナルを使用することです。

ユニコーン.rb.erb 

# Load rails+github.git into the master before forking workers
# for super-fast worker spawn times
preload_app true

before_fork do |server, worker|

  # Disconnect since the database connection will not carry over
  if defined? ActiveRecord::Base
    ActiveRecord::Base.connection.disconnect!
  end

  ##
  # When sent a USR2, Unicorn will suffix its pidfile with .oldbin and
  # immediately start loading up a new version of itself (loaded with a new
  # version of our app). When this new Unicorn is completely loaded
  # it will begin spawning workers. The first worker spawned will check to
  # see if an .oldbin pidfile exists. If so, this means we've just booted up
  # a new Unicorn and need to tell the old one that it can now die. To do so
  # we send it a QUIT.
  #
  # Using this method we get 0 downtime deploys.

  old_pid = "#{server.config[:pid]}.oldbin"
  if File.exists?(old_pid) && server.pid != old_pid
    begin
      Process.kill("QUIT", File.read(old_pid).to_i)
    rescue Errno::ENOENT, Errno::ESRCH
      # someone else did our job for us
    end
  end
end

after_fork do |server, worker|
  ##
  # Unicorn master loads the app then forks off workers - because of the way
  # Unix forking works, we need to make sure we aren't using any of the parent's
  # sockets, e.g. db connection
  # Start up the database connection again in the worker

  if defined?(ActiveRecord::Base)
    ActiveRecord::Base.establish_connection
  end

  # Redis and Memcached would go here but their connections are established
  # on demand, so the master never opens a socket
end

unicorn_init.erb

restart|reload)
  sig USR2 && echo reloaded OK && exit 0
  echo >&2 "Couldn't reload, starting '$CMD' instead"
  run "$CMD"
  ;;

次に、実行する必要がありますcap:unicorn:setup unicorn:stop unicorn:start。誰かがこの問題に直面している場合は、Railscasts on Capistrano のレシピとゼロ ダウンタイム デプロイを確認することを強くお勧めします。
