【问题描述】：

我在 vagrant box 上安装了 ChecfDK。

Brekshelf 无法正常工作。无法连接无法连接

我检查了 Iptables 等，但在网络上找不到问题。 URL 可以通过 curl 访问，并且可以在 ubuntu 盒子上正常工作。

【解决方案1】：

在尝试使用 Berkshelf 工作流程后，我发现它实际上不适用于在 Windows 主机上运行的 vagrant（或者我猜是 Virtual Box？）CentOS 来宾。这是因为上面指出的超时问题。我的hacky修复是这样的。我知道它可能会更好地推动允许您将其作为变量传递的增强功能。

现在我假设您使用的是 ChefDK 的嵌入式 ruby 和 berkshelf gem。如果不是，这些位置可能在其他地方。

在此处阅读有关特定课程的更多信息：

http://ruby-doc.org/gems/docs/b/berkshelf-api-client-1.2.0/Berkshelf/APIClient/Connection.html

[vagrant@vagrant-centos65 apache-acquity]$ cd /opt/chefdk/embedded/lib/ruby/gems/2.1.0/gems/berkshelf-api-client-1.2.0/
lib/berkshelf/api_client
[vagrant@vagrant-centos65 api_client]$ vim connection.rb

找到这个：

def initialize(url, options = {})
  options         = options.reverse_merge(retries: 3, retry_interval: 0.5,
    open_timeout: 3, timeout: 30)

改成这样：

def initialize(url, options = {})
  options         = options.reverse_merge(retries: 3, retry_interval: 0.5,
    open_timeout: 30, timeout: 30)

保存并关闭，然后重试。

这看起来可能是 berkshelf-api-client 选项的问题。默认情况下，open_timeout 选项设置为 3 秒。通过增加此超时时间，我能够成功连接。

1.9.3-p547 :010 > source = Berkshelf::Source.new("http://berkshelf.example.come")
 => #<Berkshelf::Source uri: "http://berkshelf.example.com">
1.9.3-p547 :011 > api = source.send(:api_client)
 => #<Berkshelf::APIClient::Connection:0x00000001b613f8 @url="http://berkshelf.example.com", @retries=3, @retry_interval=0.5, @parallel_manager=nil, @headers={"User-Agent"=>"Faraday v0.9.0"}, @params={}, @options=#<Faraday::RequestOptions timeout=30, open_timeout=3>, @ssl=#<Faraday::SSLOptions (empty)>, @default_parallel_manager=nil, @builder=#<Faraday::RackBuilder:0x00000001b612b8 @handlers=[Ridley::Middleware::ParseJson, Ridley::Middleware::Gzip, Faraday::Request::Retry, Faraday::Adapter::NetHttp]>, @url_prefix=#<URI::HTTP:0x000000023938a0 URL:http://berkshelf.example.com/>, @proxy=nil>
1.9.3-p547 :012 > api.universe

错误：

Berkshelf::APIClient::TimeoutError: Unable to connect to: http://berkshelf.example.com

现在，如果我修改 APIClient 使用的选项如下：

1.9.3-p547 :012 > opts = api.options
 => #<Faraday::RequestOptions timeout=30, open_timeout=3>
1.9.3-p547 :013 > opts.open_timeout = 30
 => 30
1.9.3-p547 :014 > api.instance_eval { @options = opts }
 => #<Faraday::RequestOptions timeout=30, open_timeout=30>

成功：

1.9.3-p547 :015 > api.universe
 => [#<Berkshelf::APIClient::RemoteCookbook:0x00000002a30320 @blah=blah @etc=true>]

我对红宝石不熟悉。如果你运行命令，你想尝试你的方式吗？我忘记推送示例代码。只是推。
这是显示 ruby 交互式 shell 或“irb”。因此，只需从命令行运行“irb”，然后在 irb 打开时输入“require berkshelf”。然后你就可以完成上面的练习了。
