廚師ruby_block執行導致錯誤

Question

我寫的一些chef代碼有問題。 ruby塊中的shell命令總是先於其他所有命令執行。 只要未安裝該軟件包，該垃圾箱將不可用。 每一次以這種方式進行連鎖的嘗試都以失敗告終。

錯誤：

Errno::ENOENT
-------------
No such file or directory - icinga2

  clean_icinga_version =         get_icinga_version_information.lines.first.chomp.scan(/version: [^)]*/).flatten.to_s.scan(/[0-9\.-]+/)[0].to_s.split('-')[0].gsub('.', '').to_i
  if clean_icinga_version < 280
          icinga_pki_path = '/etc/icinga2/pki'
  else
          icinga_pki_path = '/var/lib/icinga2/certs'
  end
end

任何想法如何做到這一點？

Answer 1

您還需要將代碼放在帶有block do ... end 。

Answer 2

您必須在下面的行中給出icinga2的完整路徑

get_icinga_version_information =％x [icinga2 -V]

或將此icinga2的父目錄添加到環境變量中

Answer 3

解決方案很有趣。 廚師拒絕適當的鏈接和設置條件。 它現在是一個Ohai插件，在安裝軟件包后會重新加載。
