实验环境：
puppetserver.rsyslog.org
MCollective客户端+ACtiveMQ服务端+Puppet服务端
agent1.rsyslog.org
MCollective服务端+Puppet客户端
应用:apache
agent2.rsyslog.org
MCollective服务端+Puppet客户端
应用:apache+mysql
agent3.rsyslog.org
MCollective服务端+Puppet客户端
应用:php
实验过程:
一、定义服务器变量列表
所有服务器变量列表
MY_APPLY1=apache
MY_APPLY2=mysql
MY_APPLY3=php
建议添加到所有服务器的/etc/profile文件中，然后source
主机变量：agent1.rsyslog.org
vim /etc/profile
MY_APPLY1=apache
export MY_APPLY1
export FACTERLIB=/var/lib/puppet/lib/facter
[root@agent1 ~]# source /etc/profile
主机变量：agent2.rsyslog.org
vim /etc/profile
MY_APPLY1=apache
MY_APPLY2=mysql
export MY_APPLY1
export MY_APPLY2
export FACTERLIB=/var/lib/puppet/lib/facter
主机变量：agent3.rsyslog.org
vim /etc/profile
MY_APPLY3=php
export MY_APPLY3
export FACTERLIB=/var/lib/puppet/lib/facter
二、自定义facter
1、创建目录结构
[root@puppetserver modules]# mkdir public/{modules,manifests,files,lib/facter} -p
2、服务器和节点都打开模块中的插件功能
[root@puppetserver public]# vim /etc/puppet/puppet.conf
[main]
pluginsync = true
3、编写自定义fact
[root@puppetserver public]# vim /etc/puppet/modules/public/lib/facter/my_apply1.rb
# my_apply1.rb
#
Facter.add("my_apply1") do
setcode do
Facter::Util::Resolution.exec('/bin/echo $MY_APPLY1')
end
end
[root@puppetserver public]# vim /etc/puppet/modules/public/lib/facter/my_apply2.rb
# my_apply2.rb
#
Facter.add("my_apply2") do
setcode do
Facter::Util::Resolution.exec('/bin/echo $MY_APPLY2')
end
end
[root@puppetserver public]# vim /etc/puppet/modules/public/lib/facter/my_apply3.rb
# my_apply3.rb
#
Facter.add("my_apply3") do
setcode do
Facter::Util::Resolution.exec('/bin/echo $MY_APPLY3')
end
end
4、本地建立环境变量
[root@puppetserver public]# export FACTERLIB=/etc/puppet/modules/public/lib/facter
5、测试fact（如果不正常，会显示调试信息）因为本机并未定义，所有没有显示结果
[root@puppetserver facter]# facter my_apply1
[root@puppetserver facter]# facter my_apply2
[root@puppetserver facter]# facter my_apply3
6、服务器上运行一次puppet程序，只下放自定义的facter
[root@puppetserver facter]# mco puppet -v runonce
7、查看任意节点目录下是否下载了自定义的rb模版
[root@agent2 ~]# ll /var/lib/puppet/lib/facter
total 20
-rw-r--r-- 1 root root 125 Aug 26 11:19 backup_date.rb
-rw-r--r-- 1 root root 194 Aug 26 11:19 my_apply1.rb
-rw-r--r-- 1 root root 132 Aug 26 11:19 my_apply2.rb
-rw-r--r-- 1 root root 132 Aug 26 11:19 my_apply3.rb
8、重启所有节点的mcollective服务（可通过puppet资源实现）
/etc/rc.d/init.d/mcollective restart
三、测试自定义节点是否能够被使用
1、节点端测试
[root@agent1 ~]# facter my_apply1
apache
[root@agent1 ~]# facter my_apply2
[root@agent1 ~]# facter my_apply3
[root@agent2 ~]# facter my_apply3
[root@agent2 ~]# facter my_apply2
mysql
[root@agent2 ~]# facter my_apply1
apache
[root@agent3 ~]# facter my_apply1
[root@agent3 ~]# facter my_apply2
[root@agent3 ~]# facter my_apply3
php
2、MCollective客户端测试
[root@puppetserver facter]# mco inventory agent1.rsyslog.org | grep my_apply
my_apply1 => apache
[root@puppetserver facter]# mco inventory agent2.rsyslog.org | grep my_apply
my_apply1 => apache
my_apply2 => mysql
[root@puppetserver facter]# mco inventory agent3.rsyslog.org | grep my_apply
my_apply3 => php
3、通过自定义的facter进行过滤运行puppetd服务
3.1、只运行变量my_apply3='php'的所有节点
[root@puppetserver facter]# mco puppet -v runonce mco facts -v --with-fact my_apply3='php'
Discovering hosts using the mc method for 2 second(s) .... 1
* [ ============================================================> ] 1 / 1
agent3.rsyslog.org : OK
{:summary=> "Started a background Puppet run using the 'puppet agent --onetime --daemonize --color=false --splay --splaylimit 30' command"}
---- rpc stats ----

Discovery Time: 2020.83ms
Agent Time: 1368.84ms

3.2、只运行变量 my_apply1='apache'和 my_apply2='mysql'的所有节点
[root@puppetserver facter]# mco puppet -v runonce rpc --np -F my_apply1='apache' -F my_apply2='mysql'
Discovering hosts using the mc method for 2 second(s) .... 1
agent2.rsyslog.org : OK
