作用：自动为客户端配置YUM源，为使用yum安装软件包提供便捷1、服务端配置yum模块（1）模块清单1234567891011[root@puppet ~]# tree /etc/puppet/modules/yum/。
/etc/puppet/modules/yum/├── files│ ├── yum.conf│ └── RPM-GPG-KEY-CentOS-6├── manifests│ ├── config.pp
│ ├── init.pp│ ├── install.pp│ └── params.pp└── templates说明：这里只针对centos 6.5版本测试，其他的可以此类推，需要注意的就是本地源的光盘加载问题（见测试环节）
（2）定义参数类12345678910111213141516171819[root@puppet ~]# vi /etc/puppet/modules/yum/manifests/params.ppclass yum::params {
case $operatingsystemrelease{ 6.5: { $yum_centos_descr = centos base rpm packages #本地仓库描述信息
$yum_centos_baseurl = file:///media/cdrom/ #IOS文件或光盘mount到本地的路径 $yum_centos_pki = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6 #YUMREPO文件中指定PKI文件路径
$yum_centos_pki_name = /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6 #PKI文件路径，复制一份到puppet的modules中 $yum_centos_pki_download = puppet:///modules/yum/RPM-GPG-KEY-CentOS-6
$yum_puppet_descr = puppet rpm packages for centos #puppet仓库描述信息 $yum_puppet_baseurl = http://yum.puppetlabs.com/el/6/products/$basearch #puppet仓库路径
$yum_163_descr = 163 rpm packages for centos #163仓库描述信息 $yum_163_baseurl = http://mirrors.163.com/centos/$releasever/contrib/$basearch/ #163仓库路径
} default: { fail(“Module yum is not supported on ${::operatingsystem}”) #6.5版本以外的会提示不支持，如有5.5、5.4这样的版本可按参考6.5进行参数定义
} }}注意：PKI文件RPM-GPG-KEY-CentOS-6是光盘中的存在的，系统不一样，名称也不一样，需要确认说明：变量$operatingsystemrelease是通过facter获取计算机的信息的，运行下面的命令可查看计算机相关信息：。
12[root@puppet ~]# facter | grep operatingsystemreleaseoperatingsystemrelease => 6.5（3）定义安装类123456789

class yum::install{ #1、确保yum被安装 package { yum: ensure => installed, } #2、创建光盘挂载目录 file { /media/cdrom:
ensure => directory, owner => root, group => root, } #3、确保光盘被挂载#方法一：EXEC# exec { “mount_cdrom”:
# path => “/usr/bin:/usr/sbin:/bin”,# command => /bin/mount /dev/cdrom /media/cdrom/,# creates => /media/cdrom/RPM-GPG-KEY-CentOS-6,
# require => File[/media/cdrom],# }#方法二：MOUNT mount { mount_cdrom: name => “/media/cdrom”, #挂载到的目标目录
ensure => mounted, #要求被挂载状态 fstype => “iso9660”, #光盘的文件类型，使用mount命令或cat /etc/fstab查看
device => “/dev/cdrom”, #光盘的设备，是个链接，实际指向/dev/sr0 options => “ro”, #以只读方式挂载光盘
atboot => true, #允许开机启动时挂载上 remounts => true, #允许重新挂载 require => File[/media/cdrom], #要求挂载目标目录存在
} #4、安装源前先备份 file { /etc/yum.repos.d/bak: ensure => directory, owner => root, group => root,
} exec { “repos_bak”: path => “/usr/bin:/usr/sbin:/bin”, command => mv -f /etc/yum.repos.d/[^c]*.repo /etc/yum.repos.d/bak/, #将不是小写c开头的repo文件强制移动到备份目录
creates => /etc/yum.repos.d/bak/CentOS-Base.repo, #当备份目录存在这个文件时不再执行此资源 require => File[/etc/yum.repos.d/bak], #要求备份目录存在
}}说明：新生成的repo文件都是小写c开头的，因此将不是c开头（[^c]*）的repo文件移至bak，原文件都是CentOS开头的，外加一个puppetlabs.repo，可以将[^c]*.repo改成CentOS*.repo，只将原文件备份。
（4）定义配置类123456789101112131415161718192021222324252627282930313233343536373839404142434445464748495051
52535455565758596061626364656667686970717273[root@puppet ~]# vi /etc/puppet/modules/yum/manifests/config.pp
class yum::config{ include yum::params include yum::config_file,yum::config_key,yum::config_repo}#1、定义配置文件
class yum::config_file{ file { /etc/yum.conf: #yum主配置文件yum.conf路径 ensure => present, #要求文件处于存在状态
owner => root, #属主为root group => root, #属组为root mode => 0644, #文件权限为644
source => puppet:///modules/yum/yum.conf, #自动搜索yum模块下的files目录，因此省略/files require => Class[yum::install], #要求在配置之前先安装yum软件包
} file { /etc/yum.repos.d/centos-base.repo: #设置光盘repo的一些属性，文件名是yumrepo中的标题名定义的，必须一致 ensure => present,
owner => root, group => root, mode => 0644, require => Class[yum::config_repo], #要求设置之前yumrepo资源centos-base必须存在
} file { /etc/yum.repos.d/centos-puppet.repo: ensure => present, owner => root, group => root,
mode => 0644, require => Class[yum::config_repo], } file { /etc/yum.repos.d/centos-163.repo:
ensure => present, owner => root, group => root, mode => 0644, require => Class[yum::config_repo],
}}#2、定义pki证书文件class yum::config_key{ #设置pki证书的一些属性及下载位置 file { $yum::params::yum_centos_pki_name: #证书名称在参数类中定义
ensure => present, owner => root, group => root, mode => 0644, source => $yum::params::yum_centos_pki_download, #证书下载地址在参数类中定义
}}#3、定义基本yum仓库、puppet仓库和163仓库class yum::config_repo{ yumrepo { centos-base: #创建yumrepo资源cenos-base
descr => $yum::params::yum_centos_descr, #设置描述信息 baseurl => $yum::params::yum_centos_baseurl, #设置yum源下载地址
enabled => 1, #激活yum源 gpgcheck => 1, #设置要求通过pki校验
gpgkey => $yum::params::yum_centos_pki, #设置pki文件的位置 require => Class[yum::config_key], #要求pki文件必须存在
priority => 1, #设置repo的优先级为1(越小越高) } yumrepo { centos-puppet: descr => $yum::params::yum_puppet_descr,
baseurl => $yum::params::yum_puppet_baseurl, enabled => 1, gpgcheck => 0, #不要求通过pki校验
priority => 2, } yumrepo { centos-163: descr => $yum::params::yum_163_descr, baseurl => $yum::params::yum_163_baseurl,
enabled => 1, gpgcheck => 0, priority => 3, }}说明：创建了三个YUM源，都以centos(小写)开头的，客户端安装puppet时生成了puppetlabs.repo源，因此这里的centos-puppet源也可以省略。
（7）定义yum主类1234[root@puppet ~]# vi /etc/puppet/modules/yum/manifests/init.ppclass yum { include yum::params,yum::install,yum::config
}（8）定义节点文件，调用模块1234[root@puppet ~]# vi /etc/puppet/manifests/centostest.ppnode “centostest.ewin.com” {
include ntp, yum}（9）应用节点文件12[root@puppet ~]# vi /etc/puppet/manifests/site.ppimport “centostest.pp”
（10）复制文件将以下两个文件从客户端复制一份到服务端/etc/puppet/modules/yum/files下/etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6/etc/yum.conf
注意在文件头部加上以***释，测试的时候方便分辨1### config by puppet ###2、测试（1）客户端执行测试1234[root@centostest ~]# puppet agent –server puppet.ewin.com -test –noop
Info: Caching catalog for centostest.ewin.comInfo: Applying configuration version 1415332221Notice: Finished catalog run in 1.09 seconds
（2）查看客户端日志1234567891011[root@centostest ~]# tailf /var/log/messagesNov 7 11:50:20 centostest puppet-agent[8809]: (/Stage[main]/Yum::Install/File[/media/cdrom]/ensure) created

Nov 7 11:50:24 centostest puppet-agent[8809]: Finished catalog run in 4.27 seconds结论：可看到cdrom目录创建、挂载命令执行成功、备份命令成功、同步了PKI文件和CON文件、创建了三个YUMREPO
（3）查看客户端挂载的光盘目录123456[root@centostest ~]# ls /media/cdrom/CentOS_BuildTag isolinux RPM-GPG-KEY-CentOS-Debug-6
EFI Packages RPM-GPG-KEY-CentOS-Security-6EULA RELEASE-NOTES-en-US.html RPM-GPG-KEY-CentOS-Testing-6
GPL repodata TRANS.TBLimages RPM-GPG-KEY-CentOS-6结论：挂载成功，如果用的EXEC方法将会判断RPM-GPG-KEY-CentOS-6存在时不会再执行Exec，而且此文件是原文件，不是新建的空文件。
经测试umount /media/cdrom卸载光盘后会自动重启挂载上，甚至卸载再删除/media/cdrom目录，也会恢复，有兴趣的可以试试（4）查看YUM源备份123[root@centostest ~]# ls /etc/yum.repos.d/bak/。
CentOS-Base.repo CentOS-Media.repo CentOS-Vault.repoCentOS-Debuginfo.repo puppetlabs.repo（5）查看客户端同步的文件
123456789[root@centostest ~]# cat /etc/yum.conf### config by puppet ###[main]…[root@centostest ~]# cat /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
### config by puppet ###—–BEGIN PGP PUBLIC KEY BLOCK—–Version: GnuPG v1.4.5 (GNU/Linux)…结论：从文件头部注释信息可以确认文件同步成功
（6）查看YUM list1234567891011121314[root@centostest ~]# yum clean allLoaded plugins: fastestmirror, refresh-packagekit, security
Cleaning repos: base puppetlabs-deps puppetlabs-productsCleaning up EverythingCleaning up list of fastest mirrors

centos-puppet | 2.5 kB 00:00centos-puppet/primary_db 13% [=- ] 5.9 B/s | 17 kB –:– ETA
结论：YUM三个仓库都能成功加载，通过yum clean all再yum list可观察1234567891011[root@centostest ~]# yum list puppetLoaded plugins: fastestmirror, refresh-packagekit, security。
Loading mirror speeds from cached hostfilehttp://mirrors.163.com/centos/6/contrib/x86_64/repodata/repomd.xml:

Trying other mirror.Installed Packagespuppet.noarch 3.7.1-1.el6 @puppetlabs-products
Available Packagespuppet.noarch 3.7.3-1.el6 centos-puppet结论：可以看到从163的源查找puppet超时，已安装的包是从@puppetlabs安装的，有效的包是在centos-puppet源中。
3、yum仓库资源123456yumrepo { “repo163”: #YUM源文件.repo的文件名 descr => “163 repo”, #仓库的描述 baseurl => “http://mirrors.163.com/centos/$releasever/contrib/$basearch/”, #仓库的url

device => “192.168.0.1:/share/nfs”, #挂载的来源设备 fstype => “nfs”, #文件系统类型 options => “_netdev,vers=3,tcp,rsize=8192,wsize=8192,noauto”, #其他选项
}挂载samba123456mount {“/media”: ensure => mounted, device => “//172.22.2.89/public”, fstype => cifs,
options => “username=perofu,password=123456”;}参数说明12345678910mount { mount_cdrom: name => “/media/cdrom”, #挂载到的目标目录
ensure => mounted, #要求被挂载状态 fstype => “iso9660”, #光盘的文件类型 device => “/dev/cdrom”, #光盘的设备，是个链接，指向/dev/sr0
options => “ro”, #以只读方式挂载光盘 atboot => true, #允许开机启动时挂载上 remounts => true, #允许重新挂载 require => File[/media/cdrom], #要求挂载目标目录存在
}查看文件系统类型：12345[root@centostest ~]# mount/dev/mapper/vg_centostest-lv_root on / type ext4 (rw)/dev/sda1 on /boot type ext4 (rw)
/dev/mapper/vg_centostest-lv_home on /home type ext4 (rw)/dev/sr0 on /media/cdrom type iso9660 (ro)发现以下报错，是因为没有加上options => “ro”，因为光盘是只读的。
12[mount_cdrom]) Could not evaluate: Execution of /bin/mount /media/cdrom returned 32:mount: block device /dev/sr0 is write-protected, mounting read-only
