Puppet整合Foreman(六)：Mcollective命令
一、测试
[root@puppetmaster ~]# mco find puppetagent.ewin.com [root@puppetmaster ~]# mco ping puppetagent.ewin.com time=91.49 ms ---- ping statistics ---- 1 replies max: 91.49 min: 91.49 avg: 91.49
windows客户端查看日志
C:\mcollective\mcollective.log E, [2015-05-14T14:58:24.057800 #2608] ERROR -- : agents.rb:71:in `rescue in loadagent' Loading agent puppet failed: Could not create instance of plugin MCollective::Agent::Puppet: cannot load such file -- puppet
分析问题是ruby加载puppet插件未成功报错，最终找到原因是mcollective主配置文件server.cfg中 libdir = C:\mcollective\plugins中只指向了mcollective的lib库，并没有找到puppet和facter的lib库导致！因此需要在libdir中添加puppet和facter的lib库路径libdir = C:\mcollective\plugins;C:\Puppet Labs\ Puppet\puppet\lib;C:\Puppet Labs\Puppet\facter\libdir
二、命令
mco facts #使用fact信息显示报告 mco inventory #来自nodes\collectives\subcollectives报告工具 mco nettest #测试节点网络和连接 mco nrpe #调用NRPE工具，返回监控信息 mco package #软件包的安装卸载升级 mco plugin #MC插件 mco puppet #管理puppet agent程序 mco rpc #利用RPC程序进行交互 mco service #管理系统服务
三、过滤
mco rpc service status service=puppet -S "environment=development" #-S可使用and or ! mco ping --with-agent service #--with-agent 或 -A mco ping --with-class apache #--with-class 或 -C mco ping -C /service/ mco ping --with-fact country=uk #--with-fact 或 -F mco ping -I hostname01 -I hostname02
四、管理
1、验证Agent插件
mco inventory puppetagent.ewin.com
Inventory for puppetagent.ewin.com: Server Statistics: Version: 2.8.1 Start Time: Thu Apr 23 14:35:39 +0800 2015 Config File: /etc/mcollective/server.cfg Collectives: mcollective Main Collective: mcollective Process ID: 12301 Total Messages: 14 Messages Passed Filters: 14 Messages Filtered: 0 Expired Messages: 0 Replies Sent: 13 Total Processor Time: 5.69 seconds System Time: 1.8 seconds Agents: discovery puppet rpcutil service Data Plugins: agent collective fact fstat puppet resource service Configuration Management Classes: No classes applied Facts: mcollective => 1
Data Plugins下列出了puppet说明插件安装成功。
2、查看puppet状态信息
mco puppet status
* [ ==========================================================> ] 1 / 1 puppetagent.ewin.com: Currently stopped; last completed run 27 seconds ago Summary of Applying: false = 1 Summary of Daemon Running: stopped = 1 Summary of Enabled: enabled = 1 Summary of Idling: false = 1 Summary of Status: stopped = 1 Finished processing 1 / 1 hosts in 70.91 ms
3、查看agent的puppet状态
mco rpc puppet status
* [ ==========================================================> ] 1 / 1 puppetagent.ewin.com Applying: false Daemon Running: false Lock Message: Enabled: true Idling: false Last Run: 1429771233 message: Currently stopped; last completed run 1 minutes 18 seconds ago Since Last Run: 78 Status: stopped
4、强制让所有客户端运行agent
mco puppet runonce -v
Discovering hosts using the mc method for 2 second(s) .... 1
* [ ==========================================================> ] 1 / 1
puppetagent.ewin.com : OK
{:initiated_at=>1429771209, :summary=> "Started a Puppet run using the 'puppet agent --onetime --no-daemonize --color=false --show_diff --verbose --splay --splaylimit 30' command"}
---- rpc stats ----
Nodes: 1 / 1
Pass / Fail: 1 / 0
Start Time: Thu Apr 23 14:40:13 +0800 2015
Discovery Time: 2004.83ms
Agent Time: 89.65ms
Total Time: 2094.48ms
5、强制让指定客户端运行agent
mco puppet runonce -I puppetagent.ewin.com -v
五、shell插件
shell插件可以远程执行客户端的shell命令，例如：
mco shell "cat /etc/passwd | grep puppet"
