我在厨师食谱中跟随ruby_block
ruby_block "hosts" do
block do
rc = Chef::Util::FileEdit.new("/etc/login.defs")
rc.search_file_replace_line(
/^PASS_MAX_DAYS 99999$/,
"PASS_MAX_DAYS 150"
)
rc.write_file
end
end
当我运行chef-client时，我收到了以下错误
* ruby_block[hosts] action run[2014-11-20T18:35:17+00:00] INFO: Processing ruby_block[hosts] action run (my_cookbook::default line 31)

只是为了测试我使用上面的代码编辑/etc/hosts文件条目，它的工作原理！看起来像/etc/login.defs有点连线

写入的FileEdit无法处理多字节编码。您可以修复FileEdit并向Chef提交补丁，也可以不使用它。最简单的解决方案是将所有login.defs转换为cookbook_file或template资源，从而消除对FileEdit的需求。

虽然为时已晚。但是，如果有人来这里寻找解决此类问题的方法。
file '/etc/login.defs' do
action :create
owner 'root'
group 'root'
mode '0644'
content File.read("/etc/login.defs").gsub(/^PASS_MAX_DAYS\t99999$/, "PASS_MAX_DAYS\t150")
end
厨房试运行： -
* file[/etc/login.defs] action create
- update content in file /etc/login.defs from 11fa3a to 3d7172

line cookbook通常是我们推荐的。
@ mrigesh-priyadarshi在阅读文件的答案中使用的方法，进行字符串替换，然后将其作为内容传递给文件提供者，也是完全可以接受的。
使用哪一个可能会降低个人偏好，以及任何一种方法的复杂性和主观可读性。
上面的Chef::Util::FileEdit方法不仅对多字节编码不好，而且ruby_block每次都会触发，并且不是幂等的，并且不可能链接一个仅在文件内容时才会触发的通知实际上已经改变了。
