path:指定要管理的文件或目录,必须用引号引起来.
ensure:有5个值,分别是absent,present,file,directory,link.设置present值表示【匹配文件,它会检查path值中的路径文件是否存在,如果不存在就会创建;设置absent值,删除已经存在的文件;设置directory表示创建目录,但是要删除目录需增加参数force=>true,设置link时会根据path路径创建软连接文件.
示例:
删除目录

backup:文件的内容在修改前是否备份,目前puppet支持两种备份方式,一种是将文件备份在agent上被修改文件的目录中,另一种方式将资源文件通过filebucket备份在远程服务器上。备份在agent上的方式,buckup属性的值如果是以".bak"开头的字符串的话,puppet会将变更文件备份在agent资源文件的同一目录下,备份文件的扩展名就是"."值里面的字符串,另一种远程备份需要借助filebucket资源.

注意:agent端主动备份会在file当前目录下备份.
checksum:检查文件内容是否被修改过,通过它可以检查文件的一致性。包括:md5,mtime,ctime默认使用md5.
content:可以向文件中追加内容或者通过调用template函数向erb模板中追加内容.
force:可以将一个目录变成一个连接,可用的值是true、false、yes和no,其中true与yes参数在这里均表示创建目录连接,false与no参数均表示不创建目录连接.
group:可以指定该文件的用户组,值可以使gid或系统组名.
links:定义操作符合连接的文件,可以设置的值是follow和manage.设置follow值文件复制时,会赋值文件的内容,而不是只复制连接本身;如果设置为manage值,则只复制符合连接本身.
mode:用于设置文件的权限.
owner:文件的属主.
source:指定源文件的位置,值可以是指定的远程文件的uris或者本地完整路径.
示例:
通过source同步puppet数组中多个文件.

selinux_ignore_default:selinux系列功能,实现自定义selinux.
selrange:selinux系列功能,定义范围.
selrole:selinux系列功能,定义角色.
seltype:selinux系列功能,定义类型.
seluser:selinux系列功能,定义用户.
