Question

我正在尝试将新的nova-compute节点（KUubuntu 12.04）添加到在Ubuntu 12.04 LTS上运行的单节点OpenStack（Essex版本）安装中。但是，我收到以下错误： -

错误的原因是什么以及如何解决此错误？

正如您所说，您的配置缺少--rabbit_host = ...标志，它指示在哪里可以找到OpenStack云的RabbitMQ服务。默认值为localhost。

新星接受的其他兔子旗帜：

--rabbit_host=...
--rabbit_port=...
--rabbit_virtual_host=/
--rabbit_use_ssl
--rabbit_userid=...
--rabbit_password=...
