Question

部署后我的rails应用程序（应用程序在本地机器上工作正常），我收到500内部服务器错误，我不知道有什么问题。我运行了rhc tail -a appname，因此会生成以下日志：

[ pid=422497 thr=12099720 file=utils.rb:176 time=2014-05-18 08:19:34.762 ]: *** Exception RuntimeError in Rack application object (Missing `secret_key

我的.gitignore文件：

# See https://help.github.com/articles/ignoring-files for more about ignoring files.
#
# If you find yourself ignoring temporary files generated by your text editor
# or operating system, you probably want to add a global ignore instead:
#   git config --global core.excludesfile '~/.gitignore_global'

# Ignore bundler config.
/.bundle

# Ignore the default SQLite database.
/db/*.sqlite3
/db/*.sqlite3-journal

# Ignore all logfiles and tempfiles.
/log/*.log
/tmp

secrets.yml本地文件：

# Be sure to restart your server when you modify this file.

# Your secret key is used for verifying the integrity of signed cookies.
# If you change this key, all old signed cookies will become invalid!

# Make sure the secret is at least 30 characters and all random,
# no regular words or you'll be exposed to dictionary attacks.
# You can use `rake secret` to generate a secure secret key.

# Make sure the secrets in this file are kept private
# if you're sharing your code publicly.

development:
  secret_key_base: 374b50a3e7af4ac3c8805c7706a239c32e6885a9e0b4331ce0930e341f740c4a700b932166a473ff129cfdcfbbb156b2b75911fafac71

test:
  secret_key_base: 6bb2c6ac59f9857f5ed5bb11e42cfdacb29f91e8e80fd27362ff7eb06e0e53590be74a8f515ca7c3a6820904d75f55c56d12f2d4f1f7f2

# Do not keep production secrets in the repository,
# instead read values from the environment.
production:
  secret_key_base: <%= ENV["SECRET_KEY_BASE"] %>

我的服务器中的

secrets.yml文件是相同的，只是生产是空的。

Answer 1

尝试替换config/secrets.yml中的以下行：

secret_key_base: <%=ENV['SECRET_KEY_BASE']%>

使用：

 secret_key_base: <%=ENV['OPENSHIFT_SECRET_TOKEN']%>

Answer 2

事实证明，您的secrets.yml需要在生产环境变量中设置secret_key_base。

您可以在OpenShift指南之后执行此操作：https://www.openshift.com/developers/openshift-environment-variables

由于我不使用OpenShift，你必须自己解决这个问题。
