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
