获取 sh：pvdisplay：升级到 Chef 客户端 16 后找不到命令

Question

最近我们将 chef-client 从 12.8.1 升级到 16.1.16.. 将 chef-client 从 12.8.1 升级到 16.1.16 后，出现以下错误。为了测试，我将 chef-client 恢复到 12.8.1 并且部署在 12.8.1 上工作正常。是否有任何我缺少的代码重构需要升级到 Chef 16.1.16 版本。

Answer 1

出现此问题是因为在 Chef 14.2 中向 execute 资源添加了一个新的属性。

default_env

Ruby Type: true, false | Default Value: false

When true this enables ENV magic to add path_sanity to the PATH and force the locale to English+UTF-8 for parsing output

New in Chef Client 14.2

这就是为什么 /sbin/pvcreate 是运行（尽管它失败了），而不是 pvdisplay。

在 client.rb 配置中对此有进一步的解释。

enforce_path_sanity

Turn on path sanity in resources that shellout so that expected paths like /sbin or /bin are added to the PATH. Disabled by default.

您可以用不同的方式修复它：

在您的 execute/bash 资源中为命令使用绝对路径。示例：

not_if "/sbin/pvdisplay | grep #{node['il']['ReportTomcat']['pvcreate']['drive']}"

sudo /sbin/sysctl -w net.core.somaxconn=1024

将 default_env true 添加到您的执行资源。示例：

execute 'pvcreate' do
  command "pvcreate #{node['il']['ReportTomcat']['pvcreate']['drive']}"
  default_env true
  not_if "pvdisplay | grep #{node['il']['ReportTomcat']['pvcreate']['drive']}"
end

在client.rb中启用enforce_path_sanity，这将对ShellOut的所有Chef资源生效。示例：
```
enforce_path_sanity true
```

Answer 2

enforce_path_sanity 替换为 enforce_default_paths。 github 厨师有一个未解决的问题。
