为了通用目标或目的组织在一起的一个或多个资源叫类

[root@puppet manifests]# cat test.pp
class nginx {                                #定义类名package {'nginx':                    #定义资源ensure => present,}service {'nginx':ensure => true,require => Package['nginx'],}
}
include nginx                                 #声明类
#class {'nginx'}                              #这种方式也可以声明类

执行

puppet apply test.pp -v -d

一个带传参的类

[root@puppet manifests]# cat test1.pp
$webserver = $operatingsystem ? {                      /^(?i-mx:redhat|centos|fedora)/ => 'httpd',/^(?i-mx:ubuntu|debian)/   => 'apache2',
}class httpd ($pkgname='apache2') {package {"$pkgname":ensure=>present,}service {"$pkgname":ensure=>true,require=>Package["$pkgname"],}
}class {'httpd':pkgname => $webserver ,
}

执行

puppet apply test1.pp -v -d

类的继承

[root@puppet manifests]# cat test2.pp
class nginx {package {"nginx":ensure=>present,}
}class nginx::rproxy inherits nginx {file {'/etc/nginx/nginx.conf':ensure=>file,source=>'/tmp/nginx/nginx.rproxy.conf',notify=>Service['nginx'],}service {'nginx':ensure=>true,}}class nginx::web inherits nginx {file {'/ect/nginx/nginx.conf':ensure=>file,source=>'/tmp/nginx/nginx.web.conf',notify=>Service['nginx'],}service {'nginx':ensure=>true,}
}class {'nginx::rproxy'}  或者导入
[root@puppet manifests]# cat node.pp
import "/etc/puppet/manifests/test2.pp"
include nginx::rproxy

执行

puppet apply node.pp -v -d

模块

[root@puppet puppet]# cd modules/   #创建nginx模块
[root@puppet modules]# ls
nginx
[root@puppet modules]# mkdir -pv nginx/{manifests,files,templates,lib}  #必须包含的文件夹
[root@puppet nginx]# cd manifests/
[root@puppet manifests]# ls
init.pp  nginx.rproxy.pp  nginx.web.pp   #init.pp 必须包含的文件  声明类
[root@puppet manifests]# cat init.pp nginx.rproxy.pp nginx.web.pp   #查看3个文件内容 都是刚才定义的类
class nginx {package {"nginx":ensure=>file,}
}
class nginx::rproxy inherits nginx {file {'/etc/nginx/nginx.conf':ensure=>file,source=>'puppet:///modules/nginx/nginx.rproxy.conf',  #这个路径不需要files目录  会自动找notify=>Service['nginx'],}service {'nginx':ensure=>true,}}
class nginx::web inherits nginx {file {'/ect/nginx/nginx.conf':ensure=>file,source=>'puppet:///modules/nginx/nginx.web.conf',notify=>Service['nginx'],}service {'nginx':ensure=>true,}
}[root@puppet files]# cp /tmp/nginx/nginx.* .  #copy 文件到files  依赖或者额外的配置文件都要放到files
[root@puppet files]# ls
nginx.rproxy.conf  nginx.web.conf

单独
[root@puppet manifests]# cat init.pp
class nginx {package {"nginx":ensure=>present,}file {'/etc/nginx/nginx.conf':ensure=>file,source=>'puppet:///modules/nginx/nginx.web.conf',}service {'nginx':ensure=>true,}}测试
[root@puppet manifests]# puppet apply -e 'include nginx' -v -d

一个网络模型下的模块

class jdk{                                #声明类名  将相应的rpm包文件 放到模块路径下的files目录里file {'/opt/jdk-8u45-linux-x64.rpm':source=>'puppet:///modules/jdk/jdk-8u45-linux-x64.rpm',group=>'root',owner=>'root',}file{'/etc/profile.d/java.sh':# ensure=>present,source=>'puppet:///modules/jdk/java.sh',group=>'root',owner=>'root',}exec {'install':cwd=>'/opt',path=>'/usr/local/bin:/usr/bin:/bin:',command=>'rpm -ivh jdk-8u45-linux-x64.rpm',creates=>'/usr/java/jdk1.8.0_45/bin/java',subscribe=>File['/opt/jdk-8u45-linux-x64.rpm'],require=>File['/opt/jdk-8u45-linux-x64.rpm'],}exec {'sh':cwd=>'/etc/profile.d/',creates=>'/etc/profile.d/java.sh',path=>'/usr/local/bin:/usr/bin:/bin',command=>'sh java.sh',require=>File['/etc/profile.d/java.sh'],}
}

然后在site.pp里面声明

node 'agent.cc.com'{include jdk
}
