composer.phar安装问题(cloudinit与手动)

Question

我面临一个奇怪的问题。当厨师从用户数据（cloudinit）执行时，我下面的厨师食谱失败了。

它要求HOME/COMPOSER_HOME环境变量。

然而，如果我从SSH终端手动运行chef客户端（甚至直接在终端上运行命令），它运行得很好。

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

===配方代码段===

# 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===

将environment HOME: '/root'添加到script资源（或类似资源）中。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，它会由登录shell设置，然后继承到chef客户端进程。
