puppet agent向server拉取檔案進行同步

agent向server拉取檔案，進行同步。需要對server進行配置。

假如将server側的/etc/httpd/conf/httpd.conf同步到agent。server側/etc/puppet/manifests/site.pp内容如下：file後的“/etc/httpd/conf/httpd.conf”為agent側的位置，source後為準備同步下去的檔案在master伺服器上的位置

。

node default {

    notify{"Hello World":
        name => "welcome",
        message => "Hello World!",
    }

    file {"/etc/httpd/conf/httpd.conf":
    mode => '777',owner => 'nobody',group => 'nobody',
    backup => '.bak',
    source => "puppet:///mount_point/httpd.conf",
    }
}
           

在/etc/puppet/fileserver.conf的最後添加mount_point的配置，如下：

[[email protected] puppet]# tail fileserver.conf
# allow /^(.+)\.example\.com$/
# allow_ip 192.168.100.0/24
#
# If added to auth.conf BEFORE the "path /file" rule, the rule above
# will add stricter restrictions to the extra_files mount point.
#

[mount_point]
path /etc/httpd/conf
allow *
           

 在agent端驗證（生成了.bak檔案，也有hello world的輸出）：

[[email protected] puppet]# puppet agent -t

如果遇到故障，一定要冷靜思考。如果認證什麼都正常，但是agent不報錯，但無法同步，就需要檢查server側的配置檔案，環境了。
