Puppet基础篇8-编写第二个完整测试模块yum

[root@puppetmaster modules]# tree yumyum├── files├── manifests└── templates3 directories, 0 files

2、创建package资源

[root@puppetmaster manifests]# vim install.ppclass yum::install{  package { 'yum':    ensure => installed, #要求yum这个包处于安装状态  }}

3、创建params.pp

根据操作系统版本定义repo文件中的各项条目

eg.[root@agent1 ~]# facter | grep operatingsystemrelease   系统版本factoperatingsystemrelease => 5.7

由于RedHat存在多个版本，不同版本yum源的指向不同，对应的pki认证文件也不同，因此应当设置一些变量，然后进行引用。以下只定义了系统版本为5.7、5.8、和6.4的变量，如果有其它版本效仿即可。

[root@puppetmaster manifests]# vim params.ppclass yum::params {  case $operatingsystemrelease{    5.7: {      $yum_redhat_descr = 'rhel base rpm packages'  #定义redhat光盘源的描述信息      $yum_puppet_descr = 'puppet rpm packages for rhel' #定义puppet源的描述信息      $yum_redhat_pki = 'file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release-rhel5' #定义redhat光盘源的pki认证文件位置      $yum_redhat_baseurl = 'file:///media/cdrom/Server'  #定义redhat光盘源baseurl的下载位置      $yum_puppet_baseurl = 'ftp://puppetmaster.kisspuppet.com/RHEL5U7' #定义puppet源baseurl的下载位置      $yum_redhat_pki_name = '/etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release-rhel5' #定义puppet源pki认证文件位置      $yum_redhat_pki_download = 'puppet:///modules/yum/PM-GPG-KEY/RPM-GPG-KEY-redhat-release-rhel5' #定义pki文件的服务器下载地址    }    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://puppetmaster.kisspuppet.com/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://puppetmaster.kisspuppet.com/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'    }   default: {  #定义如果没有以上版本的系统，直接报以下错误，同时也是为了方便调试      fail("Module yum is not supported on ${::operatingsystem}")    }  }}

4、创建config.pp文件

config.pp文件用于管理yum主配置文件yum.conf，repo文件的属性，pki文件的属性及下载地址和yumrepo源

[root@puppetmaster manifests]# vim config.ppclass yum::config{  include yum::params  #引用class yum::params  include yum::config_file,yum::config_key,yum::config_repo}class yum::config_file{  file { '/etc/yum.conf':  #创建file资源管理yum主配置文件yum.conf    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/etc/yum.conf', #要求从puppetmaster服务器指定目录去下载    require => Class['yum::install'], #要求在配置之前先安装yum软件包  }  file { '/etc/yum.repos.d/rhel-base.repo':  #设置光盘repo的一些属性    ensure  => present,    owner   => 'root',    group   => 'root',    mode    => '0644',    require => Class['yum::config_repo'], #要求设置之前yumrepo资源rhel-base必须存在  }  file { '/etc/yum.repos.d/rhel-puppet.repo':  #设置puppet repo的一些属性    ensure  => present,    owner   => 'root',    group   => 'root',    mode    => '0644',    require => Class['yum::config_repo'],  #要求设置之前yumrepo资源puppet必须存在  }}class yum::config_key{  #设置pki证书的一些属性及下载位置  file { $yum::params::yum_redhat_pki_name:    ensure => present,    owner  => 'root',    group  => 'root',    mode   => '0644',    source => $yum::params::yum_redhat_pki_download,  }}class yum::config_repo{   yumrepo { rhel-base: #创建yumrepo资源rhel-base    descr    => $yum::params::yum_redhat_descr, #设置描述信息    baseurl  => $yum::params::yum_redhat_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_redhat_pki, #设置pki文件的下载位置    require  => Class['yum::config_key'], #要求这个文件必须存在    priority => 1, #设置repo的优先级为1(数字越小优先级越高)  }  yumrepo { rhel-puppet:    descr    => $yum::params::yum_puppet_descr,    baseurl  => $yum::params::yum_puppet_baseurl,    enabled  => 1,    gpgcheck => 0,    priority => 2,  }}

5、创建init.pp文件

由于params.pp文件中设置的变量名称引用太长，这里可以在init.pp中将变量名简化，方便引用。

class yum(  $yum_redhat_descr        = $yum::params::yum_redhat_descr, #  $yum_puppet_descr        = $yum::params::yum_puppet_descr,  $yum_redhat_pki          = $yum::params::yum_redhat_pki,  $yum_redhat_baseurl      = $yum::params::yum_redhat_baseurl,  $yum_puppet_baseurl      = $yum::params::yum_puppet_baseurl,  $yum_redhat_pki_name     = $yum::params::yum_redhat_pki_name,  $yum_redhat_pki_download = $yum::params::yum_redhat_pki_download  ) inherits yum::params {   #设置这些变量依赖于yum::params类  include yum::config,yum::install  #包含所有子class}

因此、上面定义的class yum::config_key和yum::config_repo可以写成以下格式

class yum::config_key{  #设置pki证书的一些属性及下载位置  file { $yum_redhat_pki_name:    ensure => present,    owner  => 'root',    group  => 'root',    mode   => '0644',    source => $yum_redhat_pki_download,  }}class yum::config_repo{   yumrepo { rhel-base: #创建yumrepo资源rhel-base    descr    => $yum_redhat_descr, #设置描述信息    baseurl  => $yum_redhat_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_redhat_pki, #设置pki文件的下载位置    require  => Class['yum::config_key'], #要求这个文件必须存在    priority => 1, #设置repo的优先级为1(数字越小优先级越高)  }  yumrepo { rhel-puppet:    descr    => $yum_puppet_descr,    baseurl  => $yum_puppet_baseurl,    enabled  => 1,    gpgcheck => 0,    priority => 2,  }}

6、创建puppet.conf和pki文件

[root@puppetmaster yum]# tree filesfiles├── etc│   └── yum.conf  #可以从节点/etc/目录下copy一个yum.conf文件进行配置管理└── PM-GPG-KEY    ├── RPM-GPG-KEY-puppet-release  #自己做一个pki文件，如何做，请google    ├── RPM-GPG-KEY-redhat-release-rhel5  #在RHEL5系统/etc/pki/rpm-gpg/目录下面有对应的pki文件，将其命个别名即可    └── RPM-GPG-KEY-redhat-release-rhel6  #在RHEL6系统/etc/pki/rpm-gpg/目录下面有对应的pki文件，将其命个别名即可2 directories, 4 files

7、应用到节点上

[root@puppetmaster modules]# vim /etc/puppet/manifests/site.pp$puppetmaster = 'puppetmaster.kisspuppet.com'class environments{  include motd,puppet,yum}node default{   include environments}

8、在agent1上进行测试

[root@agent1 yum.repos.d]# mv * /tmp/  #将所有的repo文件移动到/tmp目录下[root@agent1 yum.repos.d]# puppet agent -t #运行一次puppet更新动作，可以通过以下日志看出更新info: Caching catalog for agent1_cert.kisspuppet.cominfo: Applying configuration version '1395696487'info: create new repo rhel-puppet in file /etc/yum.repos.d/rhel-puppet.reponotice: /Stage[main]/Yum::Config_repo/Yumrepo[rhel-puppet]/descr: descr changed '' to 'puppet rpm packages for rhel'notice: /Stage[main]/Yum::Config_repo/Yumrepo[rhel-puppet]/baseurl: baseurl changed '' to 'ftp://puppetmaster.kisspuppet.com/RHEL5U7'notice: /Stage[main]/Yum::Config_repo/Yumrepo[rhel-puppet]/enabled: enabled changed '' to '1'notice: /Stage[main]/Yum::Config_repo/Yumrepo[rhel-puppet]/gpgcheck: gpgcheck changed '' to '0'notice: /Stage[main]/Yum::Config_repo/Yumrepo[rhel-puppet]/priority: priority changed '' to '2'info: changing mode of /etc/yum.repos.d/rhel-puppet.repo from 600 to 644info: create new repo rhel-base in file /etc/yum.repos.d/rhel-base.reponotice: /Stage[main]/Yum::Config_repo/Yumrepo[rhel-base]/descr: descr changed '' to 'rhel base rpm packages'notice: /Stage[main]/Yum::Config_repo/Yumrepo[rhel-base]/baseurl: baseurl changed '' to 'file:///media/cdrom/Server'notice: /Stage[main]/Yum::Config_repo/Yumrepo[rhel-base]/enabled: enabled changed '' to '1'notice: /Stage[main]/Yum::Config_repo/Yumrepo[rhel-base]/gpgcheck: gpgcheck changed '' to '1'notice: /Stage[main]/Yum::Config_repo/Yumrepo[rhel-base]/gpgkey: gpgkey changed '' to 'file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release-rhel5'notice: /Stage[main]/Yum::Config_repo/Yumrepo[rhel-base]/priority: priority changed '' to '1'info: changing mode of /etc/yum.repos.d/rhel-base.repo from 600 to 644notice: Finished catalog run in 0.51 seconds[root@agent1 yum.repos.d]# lsrhel-base.repo  rhel-puppet.repo[root@agent1 yum.repos.d]# cat rhel-base.repo  #查看更新的光盘源文件[rhel-base]name=rhel base rpm packagesbaseurl=file:///media/cdrom/Serverenabled=1gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release-rhel5priority=1[root@agent1 yum.repos.d]# cat rhel-puppet.repo #插件更新的puppet源文件[rhel-puppet]name=puppet rpm packages for rhelbaseurl=ftp://puppetmaster.kisspuppet.com/RHEL5U7enabled=1gpgcheck=0priority=2
