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

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
