即使在 mongoid.yml 中指定不同的地址后，Mongoid仍会在 27017 连接到本地主机
我正在 EC2 上运行 Rails 应用程序，并使用 mongoHQ 作为 DBMS。我在 mongoid.yml 中指定了以下值，
defaults: &defaults
host: staff.mongohq.com
port: 10082
username: CodeMaster123
password: 00000000
development:
<<: *defaults
database: app-development
test:
<<: *defaults
database: app-box-test
但是当我执行 rails s 时，它会抛出一个错误，指出
/home/ubuntu/.rvm/gems/ruby-1.9.2-p290/gems/mongo-1.4.0/lib/mongo/connection.rb:
526:in `connect': Failed to connect to a master node at localhost:27017(Mongo::ConnectionFailure)
是否有方法检查 mongoid 是否正在读取 mongoid.yml？
编辑：
如果我使用错误的端口号，则会显示错误
Failed to connect to a master node at spd.mongohq.com:10092 (Mongo::ConnectionFailure)
这意味着它忽略 mongoid.yml 中指定的连接选项并连接到 localhost:27017。为什么会发生这种情况？
I'm running a rails application on EC2, and I'm using mongoHQ as DBMS. I've specified following values in mongoid.yml
defaults: &defaults
host: staff.mongohq.com
port: 10082
username: CodeMaster123
password: 00000000
development:
<<: *defaults
database: app-development
test:
<<: *defaults
database: app-box-test
But when I execute rails s it throws an error saying
/home/ubuntu/.rvm/gems/ruby-1.9.2-p290/gems/mongo-1.4.0/lib/mongo/connection.rb:
526:in `connect': Failed to connect to a master node at localhost:27017(Mongo::ConnectionFailure)
Is there a way to check whether mongoid is reading mongoid.yml?
Edit:
If I use wrong port number then it show an error
Failed to connect to a master node at spd.mongohq.com:10092 (Mongo::ConnectionFailure)
It means that it ignore the the connection options specified in mongoid.yml and connects to localhost:27017. Why is it happening?

您能否尝试在 yaml 文件中编写完整的开发选项而不是使用指针？我相信这个部门存在错误。
Can you please try writing the full options under development: in yaml file rather then using pointers? I believe there has been bugs in this departement.
Mongoid 在其当前的公共版本（2.3.4）中似乎不支持正确的 YAML 加载。您可以查看此提交以了解更多详细信息：
将选项和环境重构到它们自己的模块中
将以下内容放入您的 Gemfile 中以从最近的代码中受益提交（对于我来说在 Sinatra 下）：
Mongoid does not seem to support correctly YAML loading in its current public version (2.3.4). You can take a look at this commit for more details:
Refactor options and env into their own modules
Put the following in your Gemfile to benefit from this recent commit (for me under Sinatra):
有两个指定 DBMS 详细信息的文件，我编辑了它们，我的应用程序运行良好。
There were two files specifying DBMS details, I edited them and my application worked fine.
