通过部署MCollective+ActiveMQ模块更安全高效的触发puppet更新-原创手记-慕课网

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

<users>

</users>

</simpleAuthenticationPlugin>

</transportConnectors>

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

completion Helper for shell completion systems

facts Reports on usage for a specific fact

find Find hosts using the discovery system matching filter criteria

help Application list and help

[root@agent1 ~]# yum install mcollective-puppet-agent mcollective-puppet-common

#[root@puppetserver ~]# yum install mcollective-package-client mcollective-package-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:

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 ----

[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

Discovering hosts using the mc method for 2 second(s) .... 3
