Puppet模块(三)：puppet模块及file资源

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.pp
    notify  => 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/puppet
    rundir = /var/run/puppet
    ssldir = $vardir/ssl
[agent]
    classfile = $vardir/classes.txt
    localconfig = $vardir/localconfig
    server = <%= scope.lookupvar('puppet::params::puppetserver') %>  #参数调用格式<%= 参数 %>
    report = true
    pluginsync = false
    runinterval = 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

#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/puppet
    rundir = /var/run/puppet
    ssldir = $vardir/ssl
[agent]
    classfile = $vardir/classes.txt
    localconfig = $vardir/localconfig
    server = puppet.ewin.com
    report = true
    pluginsync = false
    runinterval = 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directory
  mode   => '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\none
  ctime        => , #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=absent
  owner        => , #指定文件的用户名或用户ID
  group        => , #指定文件的用户组名或组ID
  ignore       => , #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
}
