puppet资源yumrepo详细介绍（附案例）

2e232

The client-side description of a yum repository. Repository configurations are found by parsing /etc/yum.conf and the files indicated by the reposdir option in that file (see yum.conf(5) for details).
Most parameters are identical to the ones documented in the yum.conf(5) man page.
Continuation lines that yum supports (for the baseurl, for example) are not supported. This type does not attempt to read or verify the exinstence of files listed in the include attribute.

举例说明：
一、yum模块的目录结构树
[iyunv@linuxmaster1poc modules]# tree yum
yum
├── files
│   ├── etc
│   │   └── yum.conf
│   └── PM-GPG-KEY
│       ├── RPM-GPG-KEY-puppet-release
│       ├── RPM-GPG-KEY-redhat-release-rhel5
│       └── RPM-GPG-KEY-redhat-release-rhel6
├── manifests
│   ├── config.pp
│   ├── init.pp
│   ├── install.pp
│   └── params.pp
└── templates
5 directories, 8 files
二、yum模块source资源
[iyunv@linuxmaster1poc modules]# cat yum/files/etc/yum.conf
##---File Managed by Puppet---##
[main]
cachedir=/var/cache/yum
keepcache=0
debuglevel=2
logfile=/var/log/yum.log
distroverpkg=redhat-release
tolerant=1
exactarch=1
obsoletes=1
gpgcheck=1
plugins=1
# Note: yum-RHN-plugin doesn't honor this.
metadata_expire=1h
# installonly_limit = 3
# PUT YOUR REPOS HERE OR IN separate files named file.repo
# in /etc/yum.repos.d
三、yum模块pp文件
1、init.pp文件，包含模块其他类
[iyunv@linuxmaster1poc modules]# cat yum/manifests/init.pp
class yum{
  include yum::config,yum::install
}
2、install.pp文件，定义安装包的class
[iyunv@linuxmaster1poc modules]# cat yum/manifests/install.pp
class yum::install{
  package { 'yum':
    ensure => installed,
  }
}
3、config.pp文件，定义file、yumrepo资源
[iyunv@linuxmaster1poc modules]# cat yum/manifests/config.pp
class yum::config{
  include yum::params
  include yum::config_file,yum::config_key,yum::config_repo
}
class yum::config_file{
  file { '/etc/yum.conf':
    ensure  => present,
    owner   => 'root',
    group   => 'root',
    mode    => '0644',
    backup  => main,
    source  => 'puppet:///modules/yum/etc/yum.conf',
    require => Class['yum::install'],
  }
  file { '/etc/yum.repos.d/rhel-base.repo':
     ensure  => present,
     owner   => 'root',
     group   => 'root',
     mode    => '0644',
     backup  => main,
     require => Class['yum::config_repo'],
  }
  file { '/etc/yum.repos.d/puppet.repo':
    ensure  => present,
    owner   => 'root',
    group   => 'root',
    mode    => '0644',
    backup  => main,
    require => Class['yum::config_repo'],
  }
}
class yum::config_key{
  file { $yum::params::yum_redhat_pki_name:
    ensure => present,
    owner  => 'root',
    group  => 'root',
    mode   => '0644',
    backup => main,
    source => $yum::params::yum_redhat_pki_download,
  }
}
class yum::config_repo{
  yumrepo { rhel-base:
    descr     => $yum::params::yum_redhat_descr,
    baseurl   => $yum::params::yum_redhat_baseurl,
    enabled   => 1,
    gpgcheck  => 1,
    gpgkey    => $yum::params::yum_redhat_pki,
    require   => Class['yum::config_key'],
    priority  => 1,
  }
  yumrepo { rhel-puppet:
    descr     => $yum::params::yum_puppet_descr,
    baseurl   => $yum::params::yum_puppet_baseurl,
    enabled   => 1,
    gpgcheck  => 0,
    priority  => 2,
  }
}
4、定义params.pp文件，定义各种操作系统环境的变量，方便其他class调用
[iyunv@linuxmaster1poc modules]# cat yum/manifests/params.pp
class yum::params {
  case $operatingsystemrelease{
    5.7: {
      $yum_redhat_descr = 'rhel base rpm packages'
      $yum_puppet_descr = 'puppet rpm packages for rhel'
      $yum_redhat_pki = 'file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release-rhel5'
      $yum_redhat_baseurl = 'file:///media/cdrom/Server'
      $yum_puppet_baseurl = 'ftp://192.168.100.120/RHEL5U7'
      $yum_redhat_pki_name = '/etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release-rhel5'
      $yum_redhat_pki_download = 'puppet:///modules/yum/PM-GPG-KEY/RPM-GPG-KEY-redhat-release-rhel5'
    }
    5.8: {
      $yum_redhat_descr = 'rhel base rpm packages'
      $yum_puppet_descr = 'puppet rpm packages for rhel'
      $yum_redhat_pki = 'file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release-rhel5'
      $yum_redhat_baseurl = 'file:///media/cdrom/Server'
      $yum_puppet_baseurl = 'ftp://192.168.100.120/RHEL5U8'
      $yum_redhat_pki_name = '/etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release-rhel5'
      $yum_redhat_pki_download = 'puppet:///modules/yum/PM-GPG-KEY/RPM-GPG-KEY-redhat-release-rhel5'
    }
    6.4: {
      $yum_redhat_descr = 'rhel base rpm packages'
      $yum_puppet_descr = 'puppet rpm packages for rhel'
      $yum_redhat_pki = 'file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release-rhel6'
      $yum_redhat_baseurl = 'file:///media/cdrom'
      $yum_puppet_baseurl = 'ftp://192.168.100.120/RHEL6U4'
      $yum_redhat_pki_name = '/etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release-rhel6'
      $yum_redhat_pki_download = 'puppet:///modules/yum/PM-GPG-KEY/RPM-GPG-KEY-redhat-release-rhel6'
    }
  }
}
PS: yumrepo资源可以通过file资源进行管理，这个可以根据实际情况而定！
