centos – Chef-Solo“undefined方法`[]’为nil：NilClass”

我刚刚安装了一个新的CentOS 6.3 VM并禁用了SE Linux.下面是我运行安装 Ruby,Chef Solo并尝试配置VM的确切脚本：

#!/bin/bash
#
# Install Chef-Solo if it doesn't exist,then provision the server.
#
CHEF_FILE="https://dl.dropbox.com/u/4204671/LiquidCompass/lc-chef.tar.gz"

if [ "$#" -eq 0 ]; then
    echo "You must provide the type of server this is. (Eg: production-api,qa-api,development)"
    exit 1
fi

if [ ! -x "/usr/bin/chef-solo" ]; then
    rpm -Uvh http://rbel.frameos.org/rbel6
    yum install -y ruby ruby-devel ruby-ri ruby-rdoc ruby-shadow gcc gcc-c++ automake autoconf make curl dmidecode

    cd /tmp
    curl -O http://production.cf.rubygems.org/rubygems/rubygems-1.8.10.tgz
    tar zxf rubygems-1.8.10.tgz
    cd rubygems-1.8.10
    ruby setup.rb --no-format-executable

    gem install chef --no-ri --no-rdoc
fi

if [ -d "/etc/chef" ]; then
    rm -rf /etc/chef
fi

if [ -d "/tmp/lc-chef" ]; then
    rm -rf /tmp/lc-chef*
fi

mkdir /etc/chef 

echo "file_cache_path \"/tmp/lc-chef/chef-solo\"
cookbook_path \"/tmp/lc-chef/cookbooks\"
role_path \"/tmp/lc-chef/roles\"
json_attribs \"/etc/chef/node.json\"" > /etc/chef/solo.rb

echo "{
    \"name\": \"$1\",\"normal\": {
        \"company\": \"Liquid Compass LLC\",\"tags\": []
    },\"chef_environment\": \"_default\",\"run_list\": [
        \"role[$1]\"
    ]
}" > /etc/chef/node.json

cd /tmp
curl -O $CHEF_FILE
tar zxf lc-chef.tar.gz

chef-solo -c /etc/chef/solo.rb

不幸的是,正如我收到的脚本运行：

[2012-12-05T17:39:27-07:00] INFO: Start handlers complete.

因此,在尝试加载节点[‘php’] [‘version’]时看起来很窒息.这是在我的/tmp/lc-chef/cookbooks/liquidcompass/attributes/default.rb中定义的：

default['php']['version']             = "5.4.9"

因此看起来Chef要么没有加载属性文件,要么出现其他错误.不完全确定如何找到这个.

运行：

> RubyGems 1.8.10
>厨师10.16.2

最好的祝福,

顺便说一句,这是堆栈跟踪：

chef solo不支持默认属性.

您将需要在node目录下放置一个node.json,该目录以.json形式列出属性.

所以在你的情况下：

{
    "php": {
      "version": "5.4.9"
     }
}

如果要使用.rb格式的默认属性/任何属性,则需要使用chef-server / chef-client.
