作用：通过puppet模块自动控制客户端的puppet配置，当需要修改客户端的puppet配置时不用在客户端一一设置。
1、服务端配置puppet模块
（1）模块清单
[root@puppet ~]# tree /etc/puppet/modules/puppet/
/etc/puppet/modules/puppet/
├── files
├── manifests
│ ├── config.pp
│ ├── init.pp
│ ├── install.pp
│ ├── params.pp
│ └── service.pp
└── templates└── puppet.conf.erb
（2）定义参数类
[root@puppet ~]# vi /etc/puppet/modules/puppet/manifests/params.pp
class puppet::params {$puppetserver = "puppet.ewin.com"case $operatingsystemmajrelease{5: { #定义centos5系列的参数$puppet_release = '3.7.1-1.el5'$facter_release = '2.2.0-1.el5'}6: { #定义centos6系列的参数$puppet_release = '3.7.1-1.el6' #定义软件版本$facter_release = '2.2.0-1.el6' #定义软件版本}default: {fail("Module puppet is not supported on ${::operatingsystem}")}}
}
（3）定义安装类
[root@puppet ~]# vi /etc/puppet/modules/puppet/manifests/install.pp
class puppet::install {package { "puppet":ensure => $puppet::params::puppet_release,}package { "facter":ensure => $puppet::params::facter_release,}
}
说明：根据系统版本（centos5或centos6）来安装指定版本的puppet和facter
（4）定义配置类
[root@puppet ~]# vi /etc/puppet/modules/puppet/manifests/config.pp
class puppet::config {file { "/etc/puppet/puppet.conf":ensure => present,content => template("puppet/puppet.conf.erb"), #文件内容来源于模板owner => "root",group => "root",mode => '0644',require => Class["puppet::install"], #要求先完成install.ppnotify => Class["puppet::service"], #通知并触发service.pp}
}
说明：将配置模板传送到客户端的puppet.conf，设置用户、组、权限
（5）定义配置模板
[root@puppet ~]# vi /etc/puppet/modules/puppet/template/puppet.conf.erb
### config by puppet ###
[main]logdir = /var/log/puppetrundir = /var/run/puppetssldir = $vardir/ssl
[agent]classfile = $vardir/classes.txtlocalconfig = $vardir/localconfigserver = <%= scope.lookupvar('puppet::params::puppetserver') %> #参数调用格式<%= 参数 %>report = truepluginsync = falseruninterval = 10 #puppet 客户端默认连接到puppetmaster的时间间隔，默认30分钟，这里测试设为10秒，将会生成大量报告，建议测试完后改回1800
说明：模板调用了params.pp中的参数$puppetserver
（6）定义服务类
[root@puppet ~]# vi /etc/puppet/modules/puppet/manifests/service.pp
class puppet::service {service { "puppet":ensure => running, #确保服务puppet处于运行状态hasstatus => true, #是否支持service puppet status命令查看状态hasrestart => true, #是否支持service puppet restart命令重启服务enable => true, #是否开机启动服务require => Class["puppet::install"],}
}
（7）定义puppet主类
[root@puppet ~]# vi /etc/puppet/modules/puppet/manifests/init.pp
class puppet {include puppet::params,puppet::install,puppet::config,puppet::service
}
（8）定义节点文件，调用模块
[root@puppet ~]# vi /etc/puppet/manifests/centostest.pp
node "centostest.ewin.com" {
include ntp, yum, puppet
}
（9）应用节点文件
[root@puppet ~]# vi /etc/puppet/manifests/site.pp
import "centostest.pp"
2、测试：软件安装版本、配置文件、服务启动
（1）查看已安装版本
[root@centostest ~]# facter | grep operatingsystemmajrelease
operatingsystemmajrelease => 6
[root@centostest ~]# rpm -aq|grep puppet
puppet-3.7.3-1.el6.noarch
[root@centostest ~]# rpm -aq|grep facter
facter-2.3.0-1.el6.x86_64
（2）查看服务状态
[root@centostest ~]# /etc/init.d/puppet stop
Stopping puppet agent: [确定]
[root@centostest ~]# /etc/init.d/puppet status
puppet 已停
[root@centostest ~]# chkconfig --list | grep puppet
puppet 0:关闭 1:关闭 2:关闭 3:关闭 4:关闭 5:关闭 6:关闭
（3）查看配置文件
[root@centostest ~]# cat /etc/puppet/puppet.conf
[main]# The Puppet log directory.# The default value is '$vardir/log'.logdir = /var/log/puppet# Where Puppet PID files are kept.# The default value is '$vardir/run'.rundir = /var/run/puppet# Where SSL certificates are kept.# The default value is '$confdir/ssl'.ssldir = $vardir/ssl
[agent]# The file in which puppetd stores a list of the classes# associated with the retrieved configuratiion. Can be loaded in# the separate ``puppet`` executable using the ``--loadclasses``# option.# The default value is '$confdir/classes.txt'.classfile = $vardir/classes.txt# Where puppetd caches the local configuration. An# extension indicating the cache format is added automatically.# The default value is '$confdir/localconfig'.localconfig = $vardir/localconfig
（4）客户端执行测试
[root@centostest ~]# puppet agent --server puppet.ewin.com --test --noop

以上是重新获取YUM仓库后，第二次执行puppet agent的日志, 成功将puppet-3.7.3降为3.7.1版本，因此最好一开始指定好puppet版本安装。
（7）查看客户端测试结果
查看已安装版本：
[root@centostest ~]# rpm -aq|grep facter
facter-2.2.0-1.el6.x86_64
[root@centostest ~]# rpm -aq|grep puppet
puppet-3.7.1-1.el6.noarch
查看服务状态：
[root@centostest ~]# /etc/init.d/puppet status
puppet (pid 36125) 正在运行...
[root@centostest ~]# chkconfig --list | grep puppet
puppet 0:关闭 1:关闭 2:启用 3:启用 4:启用 5:启用 6:关闭
查看配置文件：
[root@centostest ~]# cat /etc/puppet/puppet.conf
### config by puppet ###
[main]logdir = /var/log/puppetrundir = /var/run/puppetssldir = $vardir/ssl
[agent]classfile = $vardir/classes.txtlocalconfig = $vardir/localconfigserver = puppet.ewin.comreport = truepluginsync = falseruninterval = 10
结论：软件版本成功转变成指定版本；服务启动并添加到开机启动中；配备文件成功从模板获取，参数应用成功。
3、测试配置文件的变更影响
客户端修改配置文件导致puppet服务重启：
[root@centostest ~]# echo "#add a line" >> /etc/puppet/puppet.conf
[root@centostest ~]# tailf /var/log/message
Nov 6 15:33:57 centostest puppet-agent[57545]: (/Stage[main]/Puppet::Config/File[/etc/puppet/puppet.conf]/content) content changed '{md5}29acb66e2f297a5cf2ff6cbe731998f5' to '{md5}bb6d66a4b72890ef1bfa048c0cf179d8'
Nov 6 15:33:57 centostest puppet-agent[56826]: Caught HUP; calling restart
Nov 6 15:33:57 centostest puppet-agent[57545]: (/Stage[main]/Puppet::Service/Service[puppet]) Triggered 'refresh' from 1 events
Nov 6 15:33:57 centostest puppet-agent[57545]: Finished catalog run in 1.10 seconds
Nov 6 15:33:58 centostest puppet-agent[56826]: Caught HUP; calling restart
Nov 6 15:33:58 centostest puppet-agent[56826]: Restarting with '/usr/bin/puppet agent'
Nov 6 15:33:59 centostest puppet-agent[57782]: Reopening log files
Nov 6 15:34:00 centostest puppet-agent[57782]: Starting Puppet client version 3.7.1
Nov 6 15:34:02 centostest puppet-agent[57784]: Finished catalog run in 0.63 seconds
结论：成功改变配置文件内容，触发puppet服务重启，接下来是agent启动的信息。
4、file资源
file {'nginx.conf': ensure => file, #定义类型：文件file或目录directorymode => '0640', #权限owner => root, #属于用户group => root, #属于用户组
}
其他参数
{ensure => present|absent|file|directory|link, #present检查文件是否存在，如果存在则不创建backup => , #通过filebucket备份文件，可备份到其他设备checksum => , #检查文件是否被修改，默认检测法为MD5，其他有md5lite\mtime\ctime\nonectime => , #只读属性，文件的更新时间mtime => , #只读属性content => , #文件的内容 force => , #强制删除文件、软链接及目录，确保ensure=absentowner => , #指定文件的用户名或用户IDgroup => , #指定文件的用户组名或组IDignore => , #忽略指定的匹配文件，可以匹配目录结构link => , #软链接，类似于ln命令mode => , #文件权限配置path => '/tmp/test',#文件路径，使用双引号，可用标题代替purge => , #清空目录中未在manifest中定义的文件或目录，必须与recurse=>true使用recurse => true|false|inf|remote, #递归目录recurselimit => , #递归的目录的深度，值为数字replace => true|false, #是否允许覆盖文件内容，默认为true（覆盖）source => '/home/123.txt'|'http://'|'puppet:///', #源文件，本地路径或URL路径sourceselect => firest|all, #可设置多个source源文件，本参数指定只复制每一个有效文件还是全部文件到目标target => '/tmp/testlink', #指定目录，配合ensure => link使用type => , #只读状态检查文件类型
}
