如何使用Chef递归更改目录上的所有者和组？ [英] How to recursively change the owner and group on a directory with Chef?

问题描述

资源目录只有两个可用操作：创建和删除

the resource_directory has only 2 actions available: create and delete

我需要递归更新目录的所有者和组。

I need to update the owner and group of a directory recursively.

我该怎么办

使用简单的 resource_execute ？

execute "chown-data-www" do
  command "chown -R www-data:www-data /var/www/myfoler"
  user "root"
  action :run
end

推荐答案

您可以将默认操作设置为不执行任何操作，然后拥有可能使事情搞砸的资源，通知烫发修复程序：

You can set the default action to nothing then have resources that may screw things up notify the perm fixer:

execute "chown-data-www" do
  command "chown -R www-data:www-data /var/www/myfoler"
  user "root"
  action :nothing
end

resource "that may screw up perms" do
  stuff "one two three"
  notifies :run, execute "chown-data-www"
end

使用更多选项，您可以操作：运行，但如果父文件夹已经是正确的权限，则不运行。您可以更改它以包含更深/问题的文件/目录，或者使用类似于此

with more options you could have the action :run but not if the parent folder is already the correct perms. You could alter this to include a deeper/problem file/directory, or with a find command similar to this

execute "chown-data-www" do
  command "chown -R www-data:www-data /var/www/myfoler"
  user "root"
  action :run
  not_if '[ $(stat -c %U /var/www/myfolder) = "www-data" ]'
end
