【4】puppet笔记 - 数组、类

数组：http://docs.puppetlabs.com/puppet/latest/reference/lang_datatypes.html#arrays

类：http://docs.puppetlabs.com/puppet/latest/reference/lang_classes.html

数组：

[]：内用,分隔开，就组成一个数组，如：$a = [1,"one",'two'] ，$a[0] = 1

$arr = ['one',"two","three"]
notice $arr[0]

如下，执行代码后，会在file目录下面创建f1、f2文件，并把权限改成777

$files = ["/puppet/file/f1","/puppet/file/f2"]
file {
        $files:
        ensure => present,
        mode => 777,
}

类：

class 类名 {

  puppet代码，一般多个资源放在一起，比如安装软件、配置文件、运行状态

}

include 类名 ;执行类

注：类的命名很多类似：class base , class base::linux 这二个是不同类。

class ntp {
        file {
                "/etc/ntp.conf":
                mode => 644,
                owner => root,
                group => hxw,
        }
}
class ntp::run {
        service {
                "ntpd":
                ensure => running,
        }
}
include ntp,ntp::run

[root@pclient test]# puppet apply 5.pp

类继承：

class ntp {
        file {
                "/etc/ntp.conf":
                mode => 644,
                owner => root,
                group => root,
        }
}
class ntp::autorun inherits ntp {
        service {
                "ntpd":
                ensure => running,
                enable => true,
        }
}
include ntp::autorun

[root@pclient test]# puppet apply 5.pp
Notice: Scope(Class[main]): one
Notice: Compiled catalog for pclient.onepc.com in environment production in 0.16 seconds

[root@pclient test]# chkconfig | grep ntpd
ntpd            0:关闭  1:关闭  2:启用  3:启用  4:启用  5:启用  6:关闭

class ntp::autorun inherits ntp

使用 inherits继承类
