我面临一个奇怪的问题。从用户数据（cloud-init）执行厨师时，我的以下厨师食谱失败。

它要求 HOME/COMPOSER_HOME 环境变量。

但是，如果我从 SSH 终端执行手动厨师客户端运行（甚至直接在终端上运行命令），它运行良好。

PS：composer.phar 和 composer.json 由开发者提供（捆绑在 wordpress zip 中）

== 食谱片段 ==

# Install Composer

script "install_composer" do
    interpreter "bash"
    user "root"
    cwd "#{node.apache.default_docroot}/html"
    code <<-EOH
    /opt/rh/rh-php56/root/usr/bin/php composer.phar install
    EOH
    not_if {File.exists?("#{node.default_docroot}/html/composer.lock")}
end

== 从 SSH 终端运行时 ==

  * script[install_composer] action run
    - execute "bash"  "/tmp/chef-script20160722-5397-1sjwxg9"

== Cloud-Init-Output.log 片段 ==

添加environment HOME: '/root'到您的script资源（或类似资源）。这是必需的，因为 Chef 不会为您设置此变量。当您通过 SSH 登录时，它由您的登录 shell 设置，然后继承到 chef-client 进程。
