centos + chef + vagrant 出现“网络不可达”

2024-5-29 • tag-icon

我正在尝试编写一个 Vagrantfile 来在 CentOS 6.4 图像上安装 nginx。

在我的 Vagrantfile 中我有（ip 已删除）：

  config.vm.provision :shell,
   :inline => "echo \"export http_proxy=http://10.0.0.1:3128\; export https_proxy=https://10.0.0.1:3128\" >> /etc/profile"

  config.vm.provision :shell,
   :inline => "echo \"export HTTP_PROXY=http://10.0.0.1:3128\; export HTTPS_PROXY=https://10.0.0.1:3128\" >> /etc/profile"

   config.vm.provision :shell,
    :inline => "echo \"proxy=http://10.0.0.1:3128\" >> /etc/yum.conf"

  config.vm.provision "chef_solo" do |chef|
    chef.add_recipe "nginx"
    chef.json = {
      "http_proxy" => "http://10.0.0.1:3128",
      "https_proxy" => "https://10.0.0.1:3128",
      "nginx" => {
        "install_method" => "package"
      }
    }
  end

当我运行它时，一切都很顺利，直到它尝试运行 yum 并尝试安装 GPG 文件时，我收到错误：

当我通过 ssh 进入盒子、检查代理并尝试卷曲密钥时，我没有遇到任何问题。

我也可以愉快地在盒子里使用 yum 而不会出现任何问题。

我在公司网络中的代理服务器后面，所以我想 Chef 可能没有注意代理设置。我的问题是，有没有人遇到过这种情况，或者对在代理后面运行 Chef 时无法访问网络有任何见解？

我在想如果我无法修复它，只需在厨师运行之前下载并安装密钥，但我想知道这里是否还有其他事情发生。

答案1

我认为 chef-solo 不支持代理配置。 http://docs.opscode.com/config_rb_solo.html

您可以尝试创建另一个半空的厨师配方，它将在“vagrant up”环境中获取您的http_proxy变量。

就像是：

  ENV['http_proxy'] = "http://10.0.0.1:3128"
  ENV['https_proxy'] = "https://10.0.0.1:3128"

然后将该配方添加到 vagrant 文件执行的第一步中：

  chef.add_recipe '[my_http_recipe]'

希望这可以帮助

答案2

您需要直接在 chef 对象上设置属性：

config.vm.provision :chef_solo do |chef|
  chef.http_proxy = $http_proxy
  chef.https_proxy = $https_proxy
  chef.no_proxy = $no_proxy

此外，我建议不要手动调用 shell 脚本来设置环境变量，而是使用vagrant-proxyconf插件。请注意，这确实不是传播到 chef_solo，不要从上面的代码片段中删除配置。

配置如下：

$http_proxy  = "http://10.10.1.1:4128/"
$https_proxy = "http://10.10.1.1:4128/"
$no_proxy    =  "localhost,127.0.0.1,.ag.hermle.de"

Vagrant.configure("2") do |config|
  config.proxy.http     = $http_proxy
  config.proxy.https    = $https_proxy
  config.proxy.no_proxy = $no_proxy

更新：vagrant-proxyconf 将来可能会支持 chef 代理配置，请参阅https://github.com/tmatilai/vagrant-proxyconf/issues/19。
