前言:
生产机器很多通常会新建nodes.pp文件和site.pp文件平级，存放于/etc/puppet/manifests/nodes.pp文件,这种方法比较常用.当然也有其他办法直接写入site.pp文件.
nodes.pp文件主机匹配,支持正则表达式和继承.
//:正则匹配
"":精确匹配
inherits:继承
实例:
先正则匹配然后在精确匹配.

node
/sh-
(proxy|web)\d+/ {
case
$::
hostname
{
"sh-proxy2"
: {
include apache
user {
"test1"
:
ensure => present,
}
}
"sh-web1"
: {
include nginx::nginxconf
}
}
}
|
比如sh-proxy不止sh-proxy2一台，有50台也可以匹配操作:

\d+/: {
#正则匹配
include apache
user {
"test1"
:
ensure => present,
}
}
"sh-web1"
: {
include nginx::nginxconf
}
}
}

测试agent端更新:

node节点继承(inherits)
1、新建一个admin模块,做selinux替换关闭.
/modules/admin/manifests/init.pp文件内容:
|
1

|
class admin {
exec
{
"selinux"
:
command
=>
"sed -i '/^SELINUX=/s/=.*/=disabled/g' /etc/sysconfig/selinux"
,
path => [
"/bin/"
,
"/sbin/"
,
"/usr/bin/"
,
"/usr/sbin/"
],
user => root,
group => root,
}
}
|
注意:尝试定义类名'base'报错，现象:svn无法提交,但却可以更新，update后获取到master主机ip地址目录等信息,不确实是否和系统内置变量冲突.

user {

}
}
"sh-web1"

}
}
}

注意:node节点名不能和模块名冲突,尝试定义为node admin，提交无报错，但是agent端无更新无修改无提示,修改为base以后agent端内容更新.
