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

实验步骤:

一、在Puppetserver端部署RabbitMQ
1、安装ACtiveMQ
[root@puppetserver yum.repos.d]# yum install tanukiwrapper activemq activemq-info-provider

2、配置ActiveMQ
         
           
             
               
           
         

       
           

           
       
3、启动ActiveMQ
[root@puppetserver activemq]# /etc/rc.d/init.d/activemq restart
Stopping ActiveMQ Broker...
ActiveMQ Broker was not running.
Starting ActiveMQ Broker...
[root@puppetserver activemq]# chkconfig activemq on
[root@puppetserver activemq]# netstat -nlatp | grep 61613
tcp        0      0 :::61613                    :::*                        LISTEN      3098/java

二、在Puppetserver端部署MCollective客户端
1、安装stomp gem包(也可以通过yum安装rubygem-stomp包)
[root@puppetserver ~]# gem install stomp
Successfully installed stomp-1.2.14
1 gem installed
Installing ri documentation for stomp-1.2.14...
Installing RDoc documentation for stomp-1.2.14...
2、安装Mcollective客户端
[root@puppetserver activemq]# yum install mcollective-common  mcollective-client
3、配置Mcollective连接ACtiveMQ
[root@puppetserver ~]# cat /etc/mcollective/client.cfg
topicprefix = /topic/
main_collective = mcollective
collectives = mcollective
libdir = /usr/libexec/mcollective
logger_type = console
loglevel = warn

# Plugins
securityprovider = psk
plugin.psk = 456.com

connector = stomp
#plugin.stomp.host = localhost
plugin.stomp.host = 172.16.200.100
plugin.stomp.port = 61613
plugin.stomp.user = mcollective
plugin.stomp.password = secret

# Facts
factsource = yaml
plugin.yaml = /etc/mcollective/facts.yaml


三、在所有节点上部署MCollective服务端
1、安装stomp gem包
[root@agent1 mcollective]# gem install stomp
Successfully installed stomp-1.2.14
1 gem installed
Installing ri documentation for stomp-1.2.14...
Installing RDoc documentation for stomp-1.2.14...
2、安装MCollective服务端
[root@agent1 yum.repos.d]# yum install mcollective  mcollective-common
 Installing     : ruby-irb                                                                                          1/6
 Installing     : ruby-rdoc                                                                                         2/6
 Installing     : rubygems                                                                                          3/6
 Installing     : rubygem-stomp                                                                                     4/6
 Installing     : mcollective-common                                                                                5/6
 Installing     : mcollective

2、配置MCollective服务端连接到ACtiveMQ
[root@agent1 yum.repos.d]# cat /etc/mcollective/server.cfg
topicprefix = /topic/
main_collective = mcollective
collectives = mcollective
libdir = /usr/libexec/mcollective
logfile = /var/log/mcollective.log
loglevel = info
daemonize = 1

# Plugins
securityprovider = psk
plugin.psk = 456.com

connector = stomp
plugin.stomp.host = 172.16.200.100
plugin.stomp.port = 61613
plugin.stomp.user = mcollective
plugin.stomp.password = secret

# Facts
factsource = yaml
plugin.yaml = /etc/mcollective/facts.yaml  
[root@agent1 rpms]# /etc/rc.d/init.d/mcollective restart
Shutting down mcollective:
Starting mcollective:                                      [  OK  ]

四、测试MCollective通讯是否正常
[root@puppetserver activemq]# mco help

五、部署MCollective-puppet插件
1、安装puppet插件
#[root@agent1 ~]# yum install mcollective-package-agent mcollective-package-common
[root@agent1 ~]# yum install mcollective-puppet-agent mcollective-puppet-common
#[root@puppetserver ~]# yum install mcollective-package-client mcollective-package-common
[root@puppetserver ~]# yum install mcollective-puppet-client mcollective-puppet-common

2、载入agent插件
[root@agent1 ~]# /etc/rc.d/init.d/mcollective reload-agents
Reloading mcollective agents:                              [  OK  ]

3、查看插件是否载入成功
[root@puppetserver sbin]# mco inventory agent1.rsyslog.org
Inventory for agent1.rsyslog.org:

     resource                                      

  Configuration Management Classes:
     No classes applied

  Facts:
     mcollective => 1
4、从MCollective中运行puppet进行测试（触发节点agent运行一次）
注意：所有节点puppetd服务必须关闭
[root@puppetserver sbin]# mco puppet -v runonce   #失败运行的结果
Discovering hosts using the mc method for 2 second(s) .... 0

No request sent, we did not discover any nodes.




---- rpc stats ----
          Nodes: 0 / 0
    Pass / Fail: 0 / 0
     Start Time: Sun Aug 25 14:55:29 +0800 2013
 Discovery Time: 2003.59ms
     Agent Time: 0.00ms
     Total Time: 2003.59ms

[root@puppetserver sbin]# mco puppet -v runonce #成功运行的结果
Discovering hosts using the mc method for 2 second(s) .... 1

* [ ============================================================> ] 1 / 1


agent1.rsyslog.org                     : OK  #成功启动了节点的puppetd进程
   {:summary=>      "Started a background Puppet run using the 'puppet agent --onetime --daemonize --color=false --splay --splaylimit 30' command"}

     Total Time: 3537.49ms

[root@agent1 ~]# tailf /var/log/messages   #查看同步情况
[root@agent1 ~]# watch -d /etc/rc.d/init.d/puppet status  #查看节点puppet服务变化情况

六、部署MCollective-facter插件
1、安装facter插件
[root@agent1 ~]# yum install mcollective-facter-facts
[root@agent1 ~]# ll /usr/libexec/mcollective/mcollective/facts/
total 24
-rw-r--r-- 1 root root  422 Feb 21  2013 facter_facts.ddl
-rw-r--r-- 1 root root  945 Feb 21  2013 facter_facts.rb
-rw-r--r-- 1 root root 1530 May 21 01:34 yaml_facts.rb

2、配置MCollective的facter插件
[root@agent1 ~]# vim /etc/mcollective/server.cfg
# Facts
#factsource = yaml
factsource = facter
plugin.yaml = /etc/mcollective/facts.yaml

3、重新启动MCollective服务激活facter
[root@agent1 ~]# /etc/rc.d/init.d/mcollective restart
Shutting down mcollective:
Starting mcollective:                                      [  OK  ]

4、测试facter插件
[root@puppetserver ~]# mco facts hostname -v  #查看所有节点的主机名

附加测试:部署多个节点一起测试

1、运行所有系统为RedHat，版本为6的所有节点puppetd服务
[root@puppetserver rhel5]# mco puppet -v runonce   rpc --np -F  lsbmajdistrelease='6' -F operatingsystem='RedHat'  
Discovering hosts using the mc method for 2 second(s) .... 1

agent3.rsyslog.org                     : OK

     Total Time: 3356.62ms

2、运行所有系统为RedHat，kernel版本为2.6.18的所有节点puppetd服务
[root@puppetserver rhel5]# mco puppet -v runonce   rpc --np -F  kernelversion='2.6.18'  - -F operatingsystem='RedHat'
