【1】puppet筆記 - file資源

puppet使用file資源能夠對文件進行管理,能夠對文件的內容、權限等管理。

定義一個資源，須要指定資源的類型和資源的title。

file資源語法：

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

第一行：指定資源是file類型

第二行：資源title，默認是與name的值同樣。

執行後，會在/puppet/file目錄下面建立abc文件，內容:test(換行)，屬於root用戶，文件權限:777

file類型：

ensure=>values
present:文件不存在，會自動建立
absent:刪除存在的文件
directory:建立一個目錄
link:連接文件

(file資源的文件，須要前面的路徑是存在的，以下面的/puppet/file目錄是存在的)

一、建立普通文件

在puppet/file目錄建立文件名:1，內容爲當前操做系統名稱。

注：如果建立新文件，只要content有值，那麼能夠不須要ensure=>present。

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

二、建立目錄

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

三、建立連接

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

四、刪除文件

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

客戶端能夠直接運行本地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 運行本地manifests
/var/log/puppet/ 這個目錄是在/etc/puppet.conf配置  a.log自定義

執行後查看/var/log/puppet/a.log看到如下日誌
