厨师食谱未能通过ohai undefined方法`[]'为nil:NilClass

标签: nginx chef cookbook ohai-gem

我正在制作一个厨师食谱,在我的流浪盒上设置一个带有nginx postgresql和独角兽的香草ubuntu 12.04.2,但是我遇到了nginx的麻烦,有一个例外

undefined method `[]' for nil:NilClass

安装时似乎与ohai配置有关。

我发布了我在这里的所有内容:

https://github.com/DonGiulio/mychef

这是chef-solo的输出:

更新1 我正在使用ruby-2.0.0-p247配置框,是否依赖于早期版本的ruby?

更新2 我已尝试使用ruby-1.9.3-p448,在新配置的盒子上,同样的问题,没有变化。

你能帮帮我吗?

谢谢,

您尚未说明您正在使用哪种版本的ohai和nginx食谱。

虽然我无法回答您的问题,但我可以通过使用依赖管理器(想想烹饪书的捆绑器)来提供有关管理烹饪书的一些建议。

安装Berkshelf

gem install berkshelf

创建一个Berkshelf文件

$ cat Berksfile

site :opscode

cookbook "nginx"

并使用它来下载与nginx相关的所有食谱:

$ berks install -p cookbooks
Using nginx (2.0.0)
Using apt (2.3.0)
Using bluepill (2.3.0)
Using rsyslog (1.9.0)
Using build-essential (1.4.2)
Using ohai (1.1.12)
Using runit (1.2.0)
Using yum (2.3.2)

“ - p”选项将它们放在“cookbooks”子目录中:

$ ls -d cookbooks/*
cookbooks/apt       
cookbooks/build-essential  
cookbooks/ohai     
cookbooks/runit
cookbooks/bluepill  
cookbooks/nginx            
cookbooks/rsyslog  
cookbooks/yum

我遇到了同样的错误。您可能会发现此问题的其他3个解决方案,并解释为什么它在堆栈溢出时发生here

为使用Vagrant的人提一个:只需通过Vagrantfile“chef.add_recipe()”包含食谱。

使用Berkshelf显然是在解决这个问题,我真的很喜欢它。试想一下,我们应该节省那些不想打扰安装新工具的人的时间。

尝试使用社区nexus cookbook。通过在metadata.rb中指定最新版本的nginx cookbook解决了这个问题: depends 'nginx', '>= 2.7.6'

nexus cookbook metadata.rb指定: depends "nginx", ">= 1.8.0"

除非你指定更新的版本,否则看起来厨师会在解析deps时选择1.8.0。

看起来像缺少ruby库,我通过运行安装了ruby 在Ubuntu上执行以下命令,它开始为我工作

apt-get install ruby
