puppet.dll被添加到/usr/libexec/mcollective/mcollective/agent ，一旦服务重新启动，MCollective就会识别它。

问题
虽然主机已被识别，但使用MCollective在主机上运行Puppet是不可能的。
[vagrant@localhost ~]$ mco rpc puppet runonce Discovering hosts using the mc method for 2 second(s) .... 0 No request sent, we did not discover any nodes. [vagrant@localhost ~]$ mco ping localhost.localdomain time=106.18 ms ---- ping statistics ---- 1 replies max: 106.18 min: 106.18 avg: 106.18
更新
如果Puppet Agent正在运行，问题依然存在。
[root@localhost vagrant]# mco ping localhost.localdomain time=257.15 ms ---- ping statistics ---- 1 replies max: 257.15 min: 257.15 avg: 257.15 [root@localhost vagrant]# mco rpc puppet runonce Discovering hosts using the mc method for 2 second(s) .... 0 No request sent, we did not discover any nodes.

试着通过阅读本指南来解决这个问题。
看来Puppet插件不被客户端识别。
[root@localhost mcollective]# mco inventory localhost.localdomain Inventory for localhost.localdomain: Server Statistics: Version: 2.6.1 Start Time: Sun Nov 23 12:15:07 +0000 2014 Config File: /etc/mcollective/server.cfg Collectives: mcollective Main Collective: mcollective Process ID: 5110 Total Messages: 5 Messages Passed Filters: 3 Messages Filtered: 2 Expired Messages: 0 Replies Sent: 2 Total Processor Time: 11.05 seconds System Time: 4.09 seconds Agents: discovery rpcutil Data Plugins: agent fact fstat Configuration Management Classes: No classes applied Facts: mcollective => 1
这个问题是由于Puppet插件安装不正确造成的。
README.md
The plugin has been superseded by a new Puppet agent: https://github.com/puppetlabs/mcollective-puppet-agent and is available as packages from apt.puppetlabs.com and yum.puppetlabs.com as mcollective-puppet-agent This version will stay up here till a new Puppet Commander has been written and then it will be removed.
sudo yum -y install mcollective-puppet-agent并重新启动服务解决了这个问题。
