人偶3文件递归速度非常慢 [英] Puppet 3 file recurse terribly slow

问题描述

我在Amazon Linux 2012.09上使用Puppet 3，我的清单之一是设置并重新配置一些目录.任务之一只是将文件夹所有者和组递归更改为另一个用户-但是，这需要60秒钟才能完成，并且目录中几乎没有任何内容-终端中的chown myuser:myuser/var/lib/jenkins不到一秒钟.

我的问题是:在Puppet中是否有更好/更快的方法来递归更改目录所有权?

谢谢

 file {'/var/lib/jenkins':
   ensure  => 'directory',
   owner   => myuser,
   group   => myuser,
   recurse => true,
   require => Package['jenkins'],
 }

解决方案

我也看到了这种缓慢现象，这似乎是由于Puppet单独检查了/var/lib/jenkins下的每个文件以确保其具有正确的所有者权限，这需要时间，因为$JENKINS_HOME下有很多文件.

我在Jenkins服务器上解决了这个问题，而是在顶级目录不属于所需用户的情况下，运行一个简单的chown -R命令(使用exec):

 define modify_owner() {
  exec { "modify_owner_${title}" :
    command => "/bin/chown -R ${user}:${user} '${title}'",
    onlyif => "/usr/bin/stat -c %U '${title}' | grep '^${default_user}$'"
  }
}

modify_owner { ['/var/lib/jenkins', '/var/log/jenkins', '/var/cache/jenkins']: }
 

$user/$user是我要归其所有的目录的所有者/组组合.这使我的木偶时间恢复到正常水平.

(注意:我使用了stat -c %U，但您可能需要根据操作系统来调整确切的格式设置选项.此命令打印所有者的文本名称，并在Linux上为我工作.)

I'm using Puppet 3 on Amazon Linux 2012.09, one of my manifests sets up and reconfigs some directories. One of the tasks is just changing the folder owner and group recursivelt to another user - however, this takes over a 60 seconds to complete and there is barely anything in the directory - the chown myuser:myuser /var/lib/jenkins in the terminal take less than a second.

My question is: Is there a better/faster way to change directory ownership recursively in Puppet?

Thanks

 file {'/var/lib/jenkins':
   ensure  => 'directory',
   owner   => myuser,
   group   => myuser,
   recurse => true,
   require => Package['jenkins'],
 }

解决方案

I see this slowness too, and it appears to be due to Puppet checking each file under /var/lib/jenkins individually to ensure it has the correct owner permissions, which takes time since there's a lot of files under $JENKINS_HOME.

I worked around it on our Jenkins server by instead running a simple chown -R command (with exec) whenever the top-level directory is not owned by the desired user:

define modify_owner() {
  exec { "modify_owner_${title}" :
    command => "/bin/chown -R ${user}:${user} '${title}'",
    onlyif => "/usr/bin/stat -c %U '${title}' | grep '^${default_user}$'"
  }
}

modify_owner { ['/var/lib/jenkins', '/var/log/jenkins', '/var/cache/jenkins']: }

$user/$user is the owner/group combo I want these directories to be owned by. This brought my Puppet times back down to normal levels.

(Note: I used stat -c %U but you may need to tweak the exact formatting options depending on your OS. This command printed the owner's textual name and worked for me on Linux.)
