前一篇文章介绍了mcollective的shell插件，确实很强大http://kisspuppet.com/2013/12/13/mcollectivepluginsshell/

接下来介绍mcollective的其它plugins

首先去官网下载各个插件http://yum.puppetlabs.com

1、在mcollective client端和server端安装各种plugins

mcollective-client端

[root@linuxmaster1poc ~]# rpm -qa | grep mco mcollective-service-common-3.1.2-1.noarch mcollective-client-2.2.4-1.el6.noarch mcollective-service-client-3.1.2-1.noarch mcollective-common-2.2.4-1.el6.noarch mcollective-iptables-common-3.0.1-1.noarch mcollective-filemgr-client-1.0.1-1.noarch mcollective-nrpe-client-3.0.2-1.noarch mcollective-puppet-client-1.6.0-1.noarch mcollective-nrpe-common-3.0.2-1.noarch mcollective-filemgr-common-1.0.1-1.noarch mcollective-iptables-client-3.0.1-1.noarch mcollective-puppet-common-1.6.0-1.noarch mcollective-facter-facts-1.0.0-1.noarch mcollective-package-client-4.2.0-1.noarch mcollective-package-common-4.2.0-1.noarch

mcollecitve-server端

[root@linux57poc ~]# rpm -qa | grep mco mcollective-nrpe-common-3.0.2-1 mcollective-puppet-common-1.6.0-1 mcollective-iptables-common-3.0.1-1 mcollective-iptables-agent-3.0.1-1 mcollective-2.2.4-1.el5 mcollective-package-common-4.2.0-1 mcollective-service-common-3.1.2-1 mcollective-service-agent-3.1.2-1 mcollective-puppet-agent-1.6.0-1 mcollective-package-agent-4.2.0-1 mcollective-filemgr-common-1.0.1-1 mcollective-common-2.2.4-1.el5 mcollective-facter-facts-1.0.0-1 mcollective-filemgr-agent-1.0.1-1 mcollective-nrpe-agent-3.0.2-1

以上安装可写个package模块执行，以下只针对mcollective server端，安装完成之后记得重启服务，如果写了service模块可以自动刷新

plugins.pp

class mcollective::plugins{ include mcollective::plugins_puppet, mcollective::plugins_facter, mcollective::plugins_filemgr, mcollective::plugins_iptables, # mcollective::plugins_nettest, #这个安装需要依赖包 ruby-net-ping，没找到 mcollective::plugins_nrpe, mcollective::plugins_package, mcollective::plugins_service } #mco-client need install mcollective-puppet-client and mcollective-puppet-common class mcollective::plugins_puppet{ package { ['mcollective-puppet-agent','mcollective-puppet-common']: ensure => installed, require => Class["mcollective::install"] } } #mco-client need install mcollective-facter-facts class mcollective::plugins_facter{ package { 'mcollective-facter-facts': ensure => installed, require => Class["mcollective::install"] } } #mco-client need install mcollective-filemgr-client and mcollective-filemgr-common class mcollective::plugins_filemgr{ package { ['mcollective-filemgr-agent','mcollective-filemgr-common']: ensure => installed, require => Class["mcollective::install"] } } #mco-client need install mcollective-iptables-client and mcollective-iptables-common class mcollective::plugins_iptables{ package { ['mcollective-iptables-agent','mcollective-iptables-common']: ensure => installed, require => Class["mcollective::install"] } } #mco-client need install mcollective-nettest-client and mcollective-nettest-common class mcollective::plugins_nettest{ package { ['mcollective-nettest-agent','mcollective-nettest-common']: ensure => installed, require => Class["mcollective::install"] } } #mco-client need install mcollective-nrpe-client and mcollective-nrpe-common class mcollective::plugins_nrpe{ package { ['mcollective-nrpe-agent','mcollective-nrpe-common']: ensure => installed, require => Class["mcollective::install"] } } #mco-client need install mcollective-package-client and mcollective-package-common class mcollective::plugins_package{ package { ['mcollective-package-agent','mcollective-package-common']: ensure => installed, require => Class["mcollective::install"] } } #mco-client need install mcollective-service-client and mcollective-service-common class mcollective::plugins_service{ package { ['mcollective-service-agent','mcollective-service-common']: ensure => installed, require => Class["mcollective::install"] } }

conf.pp

class mcollective::service{ service { 'mcollective': ensure => running, hasstatus => true, hasrestart => true, enable => true, subscribe => Class['mcollective::config'], subscribe => Class['mcollective::plugins'], } }

mcollective-client端安装好之后，可通过mco命令查看

[root@linuxmaster1poc ~]# mco The Marionette Collective version 2.2.4 usage: /usr/bin/mco command <options> Known commands: completion facts filemgr find help inventory iptables nrpe package ping plugin puppet rpc service shell Type '/usr/bin/mco help' for a detailed list of commands and '/usr/bin/mco help command' to get detailed help for a command

mcollective-server端安装好之后，可在mco-client端查看

[root@linuxmaster1poc ~]# mco inventory linux57poc Inventory for linux57poc: Server Statistics: Version: 2.2.4 Start Time: Fri Dec 13 08:15:46 +0800 2013 Config File: /etc/mcollective/server.cfg Collectives: mcollective Main Collective: mcollective Process ID: 23268 Total Messages: 16 Messages Passed Filters: 16 Messages Filtered: 0 Expired Messages: 0 Replies Sent: 15 Total Processor Time: 0.71 seconds System Time: 0.15 seconds Agents: #都加载上了 discovery filemgr nrpe package puppet rpcutil service shell Data Plugins: agent fstat nrpe puppet resource service Configuration Management Classes: No classes applied Facts: architecture => x86_64 augeasversion => 0.10.0 bios_release_date => 06/22/2012 bios_vendor => Phoenix Technologies LTD bios_version => 6.00 blockdevice_fd0_size => 4096 blockdevice_hdc_size => 3834736640 。。。

注意：接下来测试各种命令的操作组合，这里只举一些例子，更多信息可参考--help或者参考官网

2、组合mcollective各种plugins完成各种任务组合

2.1、停止操作系统为RHEL5.x服务器的crond任务

先查看5.x系统crond的状态，使用插件service、facts

[root@linuxmaster1poc ~]# mco service crond status -F operatingsystemmajrelease=5 * [ ============================================================> ] 2 / 2 linux57poc: running linux58poc: running Summary of Service Status: running = 2 Finished processing 2 / 2 hosts in 184.79 ms

然后通过service插件停止服务，使用插件 service、facts

[root@linuxmaster1poc ~]# mco service crond stop -F operatingsystemmajrelease=5 * [ ============================================================> ] 2 / 2 Summary of Service Status: stopped = 2 Finished processing 2 / 2 hosts in 914.76 ms

再次查看过滤的主机crond服务是否被停掉，使用插件 service、facts

[root@linuxmaster1poc ~]# mco service crond status -F operatingsystemmajrelease=5 * [ ============================================================> ] 2 / 2 linux57poc: stopped linux58poc: stopped Summary of Service Status: stopped = 2 Finished processing 2 / 2 hosts in 125.87 ms

也可以通过shell插件实现，使用到插件为shell、service、facts

[root@linuxmaster1poc ~]# mco shell "service crond status" -F operatingsystemmajrelease=5 Discovering hosts using the mc method for 2 second(s) .... 2 Host: linux57poc Statuscode: 3 Output: crond is stopped Host: linux58poc Statuscode: 3 Output: crond is stopped

2.2、使用mco对自定义fact_apply4=app的主机做一次变更，要求环境为testing，模式为noop

首先查看下那些主机具备有这个自定义fact，使用的插件为find、inventory

[root@linuxmaster1poc ~]# for i in `mco find` ; do echo $i; mco inventory $i | grep fact_apply4; done linux58poc fact_apply4 => app linux57poc linux64poc fact_apply4 => app

其次按要求做变更即可，使用到的插件为puppet，facts

[root@linuxmaster1poc ~]# mco puppet -v runonce --environment=testing --noop -F fact_apply4=app Discovering hosts using the mc method for 2 second(s) .... 2 * [ ============================================================> ] 2 / 2 linux64poc : OK {:summary=> "Started a background Puppet run using the 'puppet agent --onetime --daemonize --color=false --splay --splaylimit 30 --noop --environment testing' command"} linux58poc : OK {:summary=> "Started a background Puppet run using the 'puppet agent --onetime --daemonize --color=false --splay --splaylimit 30 --noop --environment testing' command"} ---- rpc stats ---- Nodes: 2 / 2 Pass / Fail: 2 / 0 Start Time: Fri Dec 13 09:10:50 +0800 2013 Discovery Time: 2003.32ms Agent Time: 884.34ms Total Time: 2887.67ms

变更完成后，迅速查看节点运行情况，使用到的插件为puppet

[root@linuxmaster1poc ~]# mco puppet status * [ ============================================================> ] 3 / 3 linux64poc: Currently idling; last completed run 54 seconds ago linux58poc: Currently applying a catalog; last completed run 1 minutes 12 seconds ago linux57poc: Currently stopped; last completed run 22 minutes 57 seconds ago Summary of Applying: false = 2 true = 1 Summary of Daemon Running: running = 2 stopped = 1 Summary of Enabled: enabled = 3 Summary of Idling: false = 2 true = 1 Summary of Status: idling = 1 stopped = 1 applying a catalog = 1 Finished processing 3 / 3 hosts in 263.72 ms

3、远程改所有系统为RHEL6.4主机root的密码，使用到的插件为shell，facts

[root@linuxmaster1poc ~]# mco shell "echo redhat | passwd root --stdin" -F operatingsystemrelease=6.4 Discovering hosts using the mc method for 2 second(s) .... 1 Host: linux64poc Statuscode: 0 Output: Changing password for user root. passwd: all authentication tokens updated successfully.

4、查看所有节点puppet和facter安装包的版本信息，使用到的插件为package

[root@linuxmaster1poc ~]# mco package status puppet * [ ============================================================> ] 3 / 3 linux64poc: puppet-2.7.23-1.el6.noarch linux57poc: puppet-2.7.23-1.el5.noarch linux58poc: puppet-2.7.23-1.el5.noarch Summary of Arch: noarch = 3 Summary of Ensure: 2.7.23-1.el5 = 2 2.7.23-1.el6 = 1 Finished processing 3 / 3 hosts in 635.21 ms [root@linuxmaster1poc ~]# mco package status facter * [ ============================================================> ] 3 / 3 linux58poc: facter-1.7.3-1.el5.x86_64 linux64poc: facter-1.7.3-1.el6.x86_64 linux57poc: facter-1.7.3-1.el5.x86_64 Summary of Arch: x86_64 = 3 Summary of Ensure: 1.7.3-1.el5 = 2 1.7.3-1.el6 = 1 Finished processing 3 / 3 hosts in 124.99 ms

更多的功能可通过以下方式查看：

[root@linuxmaster1poc ~]# mco puppet -h Schedule runs, enable, disable and interrogate the Puppet Agent Usage: mco puppet [OPTIONS] [FILTERS] <ACTION> [CONCURRENCY|MESSAGE] Usage: mco puppet <count|enable|status|summary> Usage: mco puppet disable [message] Usage: mco puppet runonce [PUPPET OPTIONS] Usage: mco puppet resource type name property1=value property2=value Usage: mco puppet runall [--rerun SECONDS] [PUPPET OPTIONS] The ACTION can be one of the following: count - return a total count of running, enabled, and disabled nodes enable - enable the Puppet Agent if it was previously disabled disable - disable the Puppet Agent preventing catalog from being applied resource - manage individual resources using the Puppet Type (RAL) system runall - invoke a puppet run on matching nodes, making sure to only run CONCURRENCY nodes at a time runonce - invoke a Puppet run on matching nodes status - shows a short summary about each Puppet Agent status summary - shows resource and run time summaries --force Bypass splay options when running --server SERVER Connect to a specific server or port --tags, --tag TAG Restrict the run to specific tags --noop Do a noop run --no-noop Do a run with noop disabled --environment ENVIRONMENT Place the node in a specific environment for this run --splay Splay the run by up to splaylimit seconds --no-splay Do a run with splay disabled --splaylimit SECONDS Maximum splay time for this run if splay is set --ignoreschedules Disable schedule processing --rerun SECONDS When performing runall do so repeatedly with a minimum run time of SECONDS --np, --no-progress Do not show the progress bar -1, --one Send request to only one discovered nodes --batch SIZE Do requests in batches --batch-sleep SECONDS Sleep time between batches --limit-seed NUMBER Seed value for deterministic random batching --limit-nodes, --ln, --limit COUNT Send request to only a subset of nodes, can be a percentage -j, --json Produce JSON output --display MODE Influence how results are displayed.
