服务启动起来了，但是http://127.0.0.1:3000/不能访问。后台log里的消息是：
ArgumentError (A secret is required to generate an integrity hash for cookie session data. Use config.secret_token = "some secret phrase of at least 30 characters"in config/initializers/secret_token.rb):
解决办法：
rake generate_secret_token
或者
rake secret
原因是需要加密的字符串。
