我使用以下版本 独角兽4.9 Rails 4.2.1 Ruby 2.2.1 Nginx 1.4.6 Capistrano 3.4.0
当我将我的应用程序部署到生产服务器并尝试访问其中一个页面时，我在unicorn.log文件中看到错误：＆＃34;应用程序错误：缺少secret_token和secret_key_base ＆＃39;生产＆＃39;环境，在config/secrets.yml（RuntimeError）＆＃34;
我已经阅读了有关独角兽问题和阅读ENV变量的帖子，所以我把那些＆＃34;缺失＆＃34;密钥作为config/secrets.yml中的常量值：
production:
secret_key_base: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
secret_token: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
但是我仍然得到相同的错误信息，所以它可能不是unicorn + ENV变量问题。 你能猜出这里发生了什么吗？

我注意到它会转到名为ruby/2.2.0的目录，尽管ruby -v显示了ruby 2.2.1p85。 Dows有意义吗？

建议不要在secretts.yml文件中包含您的实际密钥。
因此，使用环境变量将其恢复到更安全的版本。
secret_key_base: <%= ENV["SECRET_KEY_BASE"] %>
etc.
然后将这两行添加到Unicorn环境配置文件 $ / etc / default / unicorn
# Application specific settings
export SECRET_KEY=XXXXXXXXXXXXXXXXXXXXXXXXX
export SECRET_KEY_BASE=XXXXXXXXXXXXXXXXXXXXXXXXXX
终止并重新启动Unicorn进程以加载这些环境变量。

部署应用程序时，安全性应该是首要任务。我知道这很难，但安全不应该是你之后实施的。
我已经编写了一份指南，帮助人们使用capistrano安全地部署rails应用程序。
设置为：Nginx +独角兽+零停机时间
步骤：
它使用dotenv-rails导出环境变量，使用上面的注释，您可以在需要时安全地在应用程序中使用环境变量。
希望它有所帮助。
