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
[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
[root@puppet ~]# vi /etc/puppet/modules/yum/manifests/params.pp class 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:
[root@puppet ~]# facter | grep operatingsystemrelease operatingsystemrelease => 6.5
(3)定义安装类
[root@puppet ~]# vi /etc/puppet/modules/yum/manifests/install.pp 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
[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
[root@puppet ~]# vi /etc/puppet/modules/yum/manifests/init.pp class yum { include yum::params,yum::install,yum::config }
(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 }
(9)应用节点文件
[root@puppet ~]# vi /etc/puppet/manifests/site.pp import "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
### config by puppet ###
2、测试
(1)客户端执行测试
[root@centostest ~]# puppet agent --server puppet.ewin.com -test --noop Info: Caching catalog for centostest.ewin.com Info: Applying configuration version '1415332221' Notice: Finished catalog run in 1.09 seconds
(2)查看客户端日志
[root@centostest ~]# tailf /var/log/messages Nov 7 11:50:20 centostest puppet-agent[8809]: (/Stage[main]/Yum::Install/File[/media/cdrom]/ensure) created Nov 7 11:50:20 centostest puppet-agent[8809]: (/Stage[main]/Yum::Install/Exec[mount_cdrom]/returns) executed successfully Nov 7 11:50:22 centostest puppet-agent[8809]: (/Stage[main]/Yum::Install/File[/etc/yum.repos.d/bak]/ensure) created Nov 7 11:50:22 centostest puppet-agent[8809]: (/Stage[main]/Yum::Install/Exec[repos_bak]/returns) executed successfully Nov 7 11:50:23 centostest puppet-agent[8809]: (/Stage[main]/Yum::Config_key/File[/etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6]/content) content changed '{md5}e8e57fd1a55dc5c6d82e60a444781b96' to '{md5}a27c559bf7660f101317ac3b41a7600b' Nov 7 11:50:23 centostest puppet-agent[8809]: (/Stage[main]/Yum::Config_repo/Yumrepo[centos-base]/ensure) created Nov 7 11:50:24 centostest puppet-agent[8809]: (/Stage[main]/Yum::Config_repo/Yumrepo[centos-puppet]/ensure) created Nov 7 11:50:24 centostest puppet-agent[8809]: (/Stage[main]/Yum::Config_repo/Yumrepo[centos-163]/ensure) created Nov 7 11:50:24 centostest puppet-agent[8809]: (/Stage[main]/Yum::Config_file/File[/etc/yum.conf]/content) content changed '{md5}5d8b0bf30a8ee9d66a9cb2642186ac37' to '{md5}8c1fab4142147877a3f77f89eb8ccb7c' 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
[root@centostest ~]# ls /media/cdrom/ CentOS_BuildTag isolinux RPM-GPG-KEY-CentOS-Debug-6 EFI Packages RPM-GPG-KEY-CentOS-Security-6 EULA RELEASE-NOTES-en-US.html RPM-GPG-KEY-CentOS-Testing-6 GPL repodata TRANS.TBL p_w_picpaths 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
[root@centostest ~]# ls /etc/yum.repos.d/bak/ CentOS-Base.repo CentOS-Media.repo CentOS-Vault.repo CentOS-Debuginfo.repo puppetlabs.repo
(5)查看客户端同步的文件
[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 list
[root@centostest ~]# yum clean all Loaded plugins: fastestmirror, refresh-packagekit, security Cleaning repos: base puppetlabs-deps puppetlabs-products Cleaning up Everything Cleaning up list of fastest mirrors [root@centostest ~]# yum list Loaded plugins: fastestmirror, refresh-packagekit, security Determining fastest mirrors centos-163 | 2.9 kB 00:00 centos-163/primary_db | 1.2 kB 00:00 centos-base | 4.0 kB 00:00 ... centos-base/primary_db | 4.4 MB 00:00 ... centos-puppet | 2.5 kB 00:00 centos-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。
[root@centostest ~]# yum list puppet Loaded plugins: fastestmirror, refresh-packagekit, security Loading mirror speeds from cached hostfile http://mirrors.163.com/centos/6/contrib/x86_64/repodata/repomd.xml: [Errno 12] Timeout on http://mirrors.163.com/centos/6/contrib/x86_64/repodata/repomd.xml: (28, 'Operation too slow. Less than 1 bytes/sec transfered the last 30 seconds') Trying other mirror. Installed Packages puppet.noarch 3.7.1-1.el6 @puppetlabs-products Available Packages puppet.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
yumrepo { "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 gpgcheck => "0", #是否检查仓库中的软件包GPG签名,可设置的值为0或者1. enabled => "1", #是否开启或者禁用仓库,可设置的值为1或者0.1为开启,0为禁用 }
{ enablegroups => , #是否可以使用yumgroup参数,如yumgroup list,yumgroup install等 exclude => , #排除那些软件的安装与更新,支持shell通配符。 failovermethod => , #可设置的值为priority,roundrobin. gpgkey => , #仓库的软件包签名,GPG密钥的URL。 include => , #包含配置url. includepkgs => , #只有匹配的软件包才能安装或者更新。 keepalive => , #设置http/1.1选项,可设置的为0或者1. metadata_expire => , #元组数据的过期时间,单位时间为秒。 miirorlist => , #仓库的镜像列表。 name => , #仓库名字。 priority => , #优先级,可设置的是从1-99. protect => , #启用或者禁用对这个仓库的保护。可设置的值为0或者1. proxy => , #设置代理 }
4、mount挂载资源
挂载共享文件夹
mount { "/mount": #挂载的目标目录,等同于name参数 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samba
mount {"/media": ensure => mounted, device => "//172.22.2.89/public", fstype => cifs, options => "username=perofu,password=123456"; }
参数说明
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 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:
[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。
[mount_cdrom]) Could not evaluate: Execution of '/bin/mount /media/cdrom' returned 32: mount: block device /dev/sr0 is write-protected, mounting read-only
