Puppet/Augeas -- ins 命令在 RH6 上工作，在 RH7 上失败

  • 772

我在我的 puppet 模块中有这个构造，可以在/etc/sudoers最后一个“默认”行之后添加一行：

  augeas { "sudoers.ssh_auth_sock" :
    lens => "Sudoers.lns",
    incl => "/etc/sudoers",
    onlyif  => "match Defaults/env_keep/var[. = 'SSH_AUTH_SOCK'] size==0",
    changes => [
       # Create a new Defaults line for the two variables
       "ins Defaults after Defaults[last()]",
       # Make this Defaults line a += type
       "clear Defaults[last()]/env_keep/append",
       # assign values to the two variables
       "set Defaults[last()]/env_keep/var[1] SSH_AUTH_SOCK",
    ],
  }

它在我的 RedHat 6 机器上完美运行

 ## Next comes the main part: which users can run what software on

Notice: /Stage[main]/Sudoers/Augeas[sudoers.ssh_auth_sock]/returns: executed successfully

但它在我的 RedHat 7 机器上失败了：

Warning: Augeas[sudoers.ssh_auth_sock](provider=augeas): Loading failed for one or more files, see debug for /augeas//error output

有人可以帮助我了解发生了什么变化，或者我做错了什么，以便我可以让这个代码段在两种环境中都可以工作吗？

    谢谢@raphink

    augtool errors说

    Error in /etc/sudoers:96.12 (parse_failed)
  Iterated lens matched less than it should
  Lens: /usr/share/augeas/lenses/dist/sudoers.aug:530.10-.70:
    Last matched: /usr/share/augeas/lenses/dist/sep.aug:47.18-.40:
    Next (no match): /usr/share/augeas/lenses/dist/sudoers.aug:500.16-501.47:

    所以我检查了第 96 行/etc/sudoers，它说

    @includedir /etc/sudoers.d

    显然，@includedir现在是除了旧式语法之外的有效语法#includedir......但是（我的）augeas lens 无法识别新版本。

    (* View: includedir *)
let includedir =
  [ key /#include(dir)?/ . Sep.space . store Rx.fspath . eol ]

    我将其更改@为#in /etc/sudoers，这似乎解决了问题。
