尽管主机已被识别，但无法使用 MCollective 在主机上运行 Puppet。
[vagrant@localhost ~]$ mco rpc puppet runonce

更新
如果 Puppet Agent 正在运行，问题仍然存在。

尝试通过阅读来解决问题本指南眼下。
看起来 Puppet 插件无法被客户端识别。
[root@localhost mcollective]# mco inventory localhost.localdomain

答案1
该问题是由于 Puppet 插件未正确安装引起的。
The plugin has been superseded by a new Puppet agent: https://github.com/puppetlabs/mcollective-puppet-agent and is available as packages from apt.puppetlabs.com and yum.puppetlabs.com as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该问题。
