5.5.3　如何自动同步Puppet-Client端的yum源

Puppet-Master机器上更新了yum源后，可通过以下命令观察：

ls ll /etc/yum.repos.d/

-rw-r--r--. 1 root root 638 Feb 25 2013 CentOS-Debuginfo.repo

-rw-r--r--. 1 root root 630 Feb 25 2013 CentOS-Media.repo

-rw-r--r--. 1 root root 3664 Feb 25 2013 CentOS-Vault.repo

-rw-r--r--. 1 root root 957 Nov 4 03:46 epel.repo

-rw-r--r--. 1 root root 0 Nov 4 03:46 nginx.repo

-rw-r--r--. 1 root root 1250 Apr 12 2013 puppetlabs.repo

如果想通过Puppet-Master端将这些文件都推送到client.cn7788.com 及fabric.cn7788.com 对应的目录/etc/yum.repos.d/中去，该如何实现呢？步骤如下。

1）修改/etc/puppet/fileserver.conf文件，内容如下：

[files]

path /etc/yum.repos.d/

allow *

2）修改/etc/puppet/manifests/site.pp文件，内容如下：

file

{ "/etc/yum.repos.d/":

source => "puppet://server.cn7788.com/files/",

group => root,

owner => root,

mode => 644,

recurse => true,

force => true,

purge => true

}

客户端正确连接到Puppet服务器端后，大家可以发现，Puppet-Server会向Puppet-Client端推送文件了，分别在两台节点机器机上输入如下命令：

puppet agent --test --server server.cn7788.com

会看到两台机器的结果是一样的，输入命令的反馈结果如下：

同样，在Puppet-Client端用ll命令进行观察，可以发现客户端已经将Puppet-Server端/etc/yum.repos.d目录下的文件同步过来了，实现了此工作的需求，检查结果如下：
