Question

我需要在/etc/mongodb.conf中编辑一行

auth = true

Augeas有mongo lens，但它仅适用于augeas＆gt; 1.0

我完全停留在augeas 0.9上，因为它是epel repo中的最新版本，而我是来自github的can not compile augeas。

作为一种解决方法，我正在尝试编写自己的augeas镜头，该镜头可用于augeas 0.9

到目前为止我所拥有的是

module Spencer =

autoload xfm

let entry = key /[a-z]+/ . del /[ \t]*=[ \t]*/ "=" . store /[a-z]+/
let lns = [ entry . del "\n" "\n" ] *

test lns get "auth = false\nfoo = bar\n" = ?

let filter = incl "/etc/mongodb.conf"
let xfm = transform lns filter

当我尝试使用木偶类型将镜头应用到/etc/mongodb.conf时，我收到一个错误“迭代镜头匹配得比它应该少”。

镜头有什么问题？
如何从命令行测试镜头并将傀儡从等式中取出？

Answer 1

RHEL 6.4刚升级到Augeas 1.0。请参阅https://rhn.redhat.com/errata/RHSA-2013-1537.html。

您应该能够重建软件包，或者等待CentOS为您完成。

Answer 2

我和augeas＆amp;有过类似的问题。木偶。应用更改似乎每次都以错误Could not evaluate: Save failed with return code false结束。结果证明这是一个语法问题。我有：

set spec[user = '%somegroup']/host_group/command/tag  NOPASSWD

（注意tag和NOPASSWD之间的两个空格。当我用一个空的空间尝试相同的命令时，问题就解决了。查看模板/镜头（spencer.aug，第6.10-.37行）可能会提供一些问题的线索。
