一、添加任务计划

vim/etc/puppet/mainfests/site.pp

cron { 'ntp update':

        ensure => present,

        command => "ntpupdate ntp.time.com",

        user    => "root",

        minute  => "0",

        hour    => "0",

        monthday => "*",

        month    => '*',

        weekday  => '*',

}

二、删除任务计划

vim/etc/puppet/mainfests/site.pp

cron { 'ntp update':

        ensure => absent,

        command => "ntpupdate ntp.time.com",

        user    => "root",

        minute  => "0",

        hour    => "0",

        monthday => "*",

        month    => '*',

        weekday  => '*',

}
