puppet写ntp模块
实验1 ntpd的部署
实验基本环境
debian7
三台主机（没有域，已经做好认证）
debian（master 2.7.23，debian7），liuliancao（agent 2.7.23，debian7），luqixue（agent，3.6.2，Centos 7）
debian master写模块

root@debian:/etc/puppet# cat manifests/nodes/liuliancao.ppnode ‘liuliancao‘ { class {‘ntp‘:

}这个时候liuliancao端再进行同步发现

另一台机器，也一样奏效了，主文件的清单
root@debian:/etc/puppet# cat manifests/nodes/luqixue.ppnode ‘luqixue‘ { class {‘ntp‘:
enable => false, ensure => stopped,
}
}客户机luqixue执行的结果反馈：由于我版本兼容性问题，所以前面报错，忽略不计哈
