我正在尝试使用chef-solo在我的服务器上安装postgresql。我通过自己做引导程序并在脚本中手动包含build-esential包来完成这项工作。现在我想使用knife-solo来处理引导，我在定义执行配方的顺序时遇到了问题。
我想在postgresql之前安装build-essential软件包。这是我正在建立的服务器的json文件
{
"dbuser": "myuser",
"dbpass": "mypassword",
"postgresql":{"password":{"postgres":"mypassword"}},
"passenger":{"version":"3.0.14", "max_pool_size":"2"},
"default_attributes":{"build_essential":{"compiletime": "true"}},
"run_list": [
"recipe[build-essential]",
"role[web_server]",
"recipe[sqlite]",
"recipe[postgresql::server]",
"recipe[pope::default]"
]
}
当我发出命令
时knife cook <user>@<my server's ip>
我收到此错误
WARNING: No knife configuration file found

最简单的解决方案是更新本地postgresql cookbook。您观察到的问题已在最近版本的cookbook中修复（所有版本＆gt; = 1.0.0）。
现在他们是如何解决的？首先，您会注意到客户端配方已分为client.rb和ruby.rb。前者只是安装操作系统包，后者是Ruby gem，用于后续的Chef运行。正如您所观察到的那样，安装该gem需要先安装build-essentials。这由名为node['build-essential']['compile_time']的{{3}}食谱使用的新属性控制。这确保在编译期间安装所需的包，即，在包含构建必需配方时直接安装。
要理解为什么这很重要，你必须先了解一下build-essential，即执行配方源代码的编译时间和后续转换的资源集合之间的差异，以下收敛，其中执行资源以将系统移向预期状态。
通常，大多数实际更改都是在收敛阶段完成的。然而，有时需要在编译阶段之前构建一些东西，以便能够使用它来确定哪些资源与此处的情况完全一致。当我们尽早安装到pg gem时，我们可以使用它早期与数据库通信，例如决定是否创建数据库。
