composer.phar 安装问题（cloudinit 与手动）

Question

我遇到了一个奇怪的问题。当从用户数据 (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（甚至运行直接在终端上执行命令）手动执行 chef-client 运行就没问题了。

PS：composer.phar 和 composer.json 由开发人员提供（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

== 当来自 SSH 终端的运行 ==

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

== Cloud-Init-Output.log 片段 ==

Answer 1

将 environment HOME: '/root' 添加到您的 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，它由您的登录设置 shell，然后继承到 chef-client 进程。
