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:
node /sh-(proxy|web)\d+/ { case $::hostname { /sh-proxy\d+/: { #正则匹配 include apache user {"test1": ensure => present, } } "sh-web1": { include nginx::nginxconf } } }
测试agent端更新:
[[email protected] puppet]# puppet agent -t Info: Retrieving pluginfacts Info: Retrieving plugin Info: Caching catalog for sh-proxy2.localdomain Info: Applying configuration version ‘1505706252‘ Notice: /Stage[main]/Apache/Package[httpd]/ensure: created Notice: Finished catalog run in 8.69 seconds
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:
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.
manifests/nodes.pp文件内容. node base { include admin }
node /sh-(proxy|web)\d+/ inherits base { case $::hostname { /sh-proxy\d+/: { include apache user {"test1": ensure => present, } } "sh-web1": { include nginx::nginxconf } } }
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.
