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

├── manifests
│ ├── config.pp
│ ├── init.pp
│ ├── install.pp
│ ├── params.pp
│ └── service.pp
└── templates
└── puppet.conf.erb
（2）定义参数类

# 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

# 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

# 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

# vi /etc/puppet/modules/puppet/template/puppet.conf.erb
### config bypuppet ###
logdir = /var/log/puppet
rundir = /var/run/puppet
ssldir = $vardir/ssl
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

# 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
1
2

4
# 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
# vi /etc/puppet/manifests/centostest.pp
node "centostest.ewin.com" {
include ntp, yum, puppet
}
（9）应用节点文件
1
2
# 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

# facter | grep operatingsystemmajrelease
operatingsystemmajrelease => 6
# rpm -aq|grep puppet
puppet-3.7.3-1.el6.noarch
# rpm -aq|grep facter
facter-2.3.0-1.el6.x86_64
（2）查看服务状态

# /etc/init.d/puppet status

# chkconfig --list | grep puppet

#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：

# rpm -aq|grep facter
facter-2.2.0-1.el6.x86_64
# rpm -aq|grep puppet
puppet-3.7.1-1.el6.noarch
查看服务状态：

# cat /etc/puppet/puppet.conf

logdir = /var/log/puppet
rundir = /var/run/puppet
ssldir = $vardir/ssl
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。
