【问题描述】：
部署我的 Rails 应用程序后（该应用程序在本地机器上运行良好），我收到 500 内部服务器错误，我不知道出了什么问题。我跑了rhc tail -a appname，所以它会生成以下日志：
[ 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"] %>
我服务器中的secrets.yml文件是一样的，只是生产是空的。
【问题讨论】：
-
您的 secrets.yml 文件中有 secret_key_base 值吗？
