exec命令管控资源
[root@centos7 ~]# cat exec.pp 执行密等的命令
exec{'mktemp':
command => 'mktemp -d /tmp/dir.XXX',
path => '/bin:/sbin:/usr/bin:/usr/sbin',
}
[root@centos7 ~]# cat exec.pp
exec{'mktemp':
command => 'mktemp -d /tmp/dir.XXX',
path => '/bin:/sbin:/usr/bin:/usr/sbin',
}
exec{'mkdir':
command => 'mkdir /tmp/mydir',
path => '/bin:/sbin:/usr/bin:/usr/sbin',
# create => '/tmp/mydir',
unless => 'test -d /tmp/mydir', 条件是执行命令
}
[root@centos7 ~]# puppet apply -v exec.pp 第一次执行两个资源都执行

command：要执行的任务；
ensure：present/absent；
hour：
minute:
monthday:
month:
weekday：
user：以哪个用户的身份运行命令
target：添加为哪个用户的任务
name：cron job的名称；
示例：
[root@centos7 ~]# vim ch.pp
cron{'timesync':
command => '/usr/sbin/ntpdate 172.16.0.1 &> /dev/null',
ensure => present,
minute => '*/3',
user => 'root',
}
[root@centos7 ~]# puppet apply -v --noop ch.pp
