heroku mongohq和mongoid Mongo :: ConnectionFailure [英] heroku mongohq and mongoid Mongo::ConnectionFailure

问题描述

UPDATE 2012年6月9日：

在heroku中使用mongoid 3.0.0.rc进行安装，请参阅以下要点： https://gist.github.com/2900804

UPDATE 22th Jan 2011：

>

Uri现在优先于mongoid.yml

https://github.com/mongoid/mongoid/issues/issue/266

更新2010年8月12日：虽然我从Jackues Crocker得到了可接受的答案，但是这个问题的一些方面使得它很容易搞砸！它又发生在我身上，我决定研究mongoid源代码。所以，这里是：

目前， 主机：端口：名称/数据库：设置在uri上使用PRECEDENCE ：设置。因此，由于对 localhost：xxxx 的请求而不是 flame.local.mongohq.com:xxxx，因此发生了非常无意义的错误消息

;默认
host：localhost< - 这是'OVERWRITES'主机在uri！

产量：
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<。主持人：从默认情况下将是一个应用，而不是你的主机。
uri：<％= ENV ['MONGOHQ_URL']％>

通过删除主机：修改默认值，和/或删除

---

ORIGINAL Q：

我已经添加了 mongoHQ a>插件，用于在heroku上 mongodb 。它崩溃了：

  connect_to_master'：无法连接到任何给定的主机：端口（Mongo :: ConnectionFailure）
  

在线说明（ mongoid 运行ruby 1.9.1和rails 3-beta。

我的感觉是说有一些 ENV ['MONGOHQ_URL'] ，它表示MongoHQ插件集，但我没有设置 MONGOHQ_URL 在我的应用程序中的任何位置。我猜这个问题在我的
mongoid.yml中？

 默认值：& defaults 
主机：localhost 
 
开发：
 <<：* defaults 
 database：aliado_development 
 
 test：
<<：* defaults 
 database：aliado_test 
 
 ＃在您的prod服务器上设置这些环境变量
生产：
 <：lt：：* defaults 
 host：<％= ENV ['MONGOID_HOST']％> 
 port：<％= ENV ['MONGOID_PORT']％> 
用户名：<％= ENV ['MONGOID_USERNAME']％> 
密码：<％= ENV ['MONGOID_PASSWORD']％> 
数据库：<％= ENV ['MONGOID_DATABASE']％> 
  

它可以在本地正常工作，但在heroku上失败，更多堆栈跟踪：

 ... .. 
  

这一切都可以在本地运行，包括测试和应用。我没有想法......任何建议？

PS：有高repu的人创建标签'mongohq'？

解决方案Mongoid（master）现在在mongoid.yml中有一个URI选项。所以你可以这样做：

 制作：
 uri：<％= ENV ['MONGOHQ_URL']％> 
  

要在您的项目中使用mongoid master，请在您的Gemfile中设置它。

  gemmongoid，：：git => [e-mail]：mongoid / mongoid.git
  

希望新宝石即将发布这将清理东西。

UPDATE 9th june 2012:

Setup with mongoid 3.0.0.rc at heroku, see this gist: https://gist.github.com/2900804

UPDATE 22th jan 2011:

Uri now takes precedence in mongoid.yml

https://github.com/mongoid/mongoid/issues/issue/266

UPDATE 12th aug 2010: Although I got an accepted answer 6th may from Jackues Crocker, there are aspects of this issue that makes it easy to mess up! It happened to me yet again and I decided to research the mongoid source code. So, here it goes:

Currently, host: port: name/database: settings TAKE PRECEDENCE OVER the uri: setting. Hence, the awfully uninformative error message is happening due to a request to localhost:xxxx and not to flame.local.mongohq.com:xxxx

This will break!

defaults: &defaults
  host: localhost  <- THIS 'OVERWRITES' host in the uri!

production:
  <<: *defaults    <- BE CAREFUL WITH WHAT YOU BRING IN. THE host: FROM DEFAULTS WILL BE THE ONE APPLIED, not your uri host.
  uri: <%= ENV['MONGOHQ_URL'] %>

fix it with either removing the host: in defaults, and/or removing the <<: *defaults

---

ORIGINAL Q:

I have added the mongoHQ addon for mongodb at heroku. It crashes with :

connect_to_master': failed to connect to any given host:port (Mongo::ConnectionFailure)

The descriptions online (heroku mongohq) are more directed towards mongomapper, as I see it. I'm running ruby 1.9.1 and rails 3-beta with mongoid.

My feeling says that there's something with ENV['MONGOHQ_URL'], which it says the MongoHQ addon sets, but I haven't set MONGOHQ_URL anywhere in my app. I guess the problem is in my mongoid.yml ?

defaults: &defaults
  host: localhost

development:
  <<: *defaults
  database: aliado_development

test:
  <<: *defaults
  database: aliado_test

# set these environment variables on your prod server
production:
  <<: *defaults
  host: <%= ENV['MONGOID_HOST'] %>
  port: <%= ENV['MONGOID_PORT'] %>
  username: <%= ENV['MONGOID_USERNAME'] %>
  password: <%= ENV['MONGOID_PASSWORD'] %>
  database: <%= ENV['MONGOID_DATABASE'] %>

It works fine locally, but fails at heroku, more stack trace:

==> crashlog.log <==
Cannot write to outdated .bundle/environment.rb to update it

.....

It all works locally, both tests and app. I'm out of ideas... Any suggestions?

PS: Somebody with high repu mind create the tag 'mongohq'?

解决方案

Mongoid (master) now has a URI option in mongoid.yml. So you could do:

production:
  uri: <%= ENV['MONGOHQ_URL'] %>

To use mongoid master in your project, set this in your Gemfile

gem "mongoid", :git => "[e-mail]:mongoid/mongoid.git"

Hopefully a new gem will be released soon which will clean things up.
