【1】puppet笔记 - file资源

puppet使用file资源可以对文件进行管理,可以对文件的内容、权限等管理。

定义一个资源，需要指定资源的类型和资源的title。

file资源语法：

file {
"/puppet/file/abc":
name=> "/puppet/file/abc",
content=>"test\n",
owner=> root,
mode=> 777;
}

第一行：指定资源是file类型

第二行：资源title，默认是与name的值一样。

执行后，会在/puppet/file目录下面创建abc文件，内容:test(换行)，属于root用户，文件权限:777

file类型：

}

ensure=>values
present:文件不存在，会自动创建
absent:删除存在的文件
directory:创建一个目录
link:链接文件

(file资源的文件，需要前面的路径是存在的，如下面的/puppet/file目录是存在的)
1、创建普通文件
在puppet/file目录创建文件名:1，内容为当前操作系统名称。
注：若是创建新文件，只要content有值，那么可以不需要ensure=>present。

file {
"/puppet/file/1":
ensure=>present,
content => $operatingsystem,
owner => root,
mode => 644;
}

2、创建目录

file {
"/puppet/file/mulu":
ensure=>directory,
mode=>644;
}

3、创建链接

file {
"/puppet/file/link":
ensure=>link,
target=>"/etc/passwd";
}

4、删除文件

file {
"/puppet/file/1":
ensure=>absent,
content => $operatingsystem,
owner => root,
mode => 644;
}

客户端可以直接运行本地manifest，命令：puppet apply -l /var/log/puppet/a.log 1.pp

[root@pclient test]# puppet apply -l /var/log/puppet/a.log 1.pp
Puppet apply 运行本地manifests
/var/log/puppet/ 这个目录是在/etc/puppet.conf配置  a.log自定义

执行后查看/var/log/puppet/a.log看到以下日志
