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

knife cook <user>@<my server's ip>

我收到这个错误

WARNING: No knife configuration file found

解决方法

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> = 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拆分为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.这是由build-essential食谱使用的一个名为node [‘build-essential’] [‘compile_time’]的新属性控制的.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,你必须要了解一下Anatomy of a Chef Run,即执行配方的源代码的编译时间和后续转换的资源集合是否构建之间的差异,以及资源的后续收敛执行以将系统移向预期状态.

通常,大多数实际变化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.当我们早期安装到pg gem时,我们可以使用它来尽早与数据库通信,例如决定是否创建数据库.
