Openstack 无法访问本地主机5672上的AMQP服务器：[Errno 111]

我正在尝试将不同虚拟机上的其他计算节点添加到预安装的openstack中。我已禁用防火墙服务，启用ping其他虚拟机。。但计算节点仍无法向控制器节点上运行的Rabbitmq服务注册。。 这是我的nova.conf文件

[glance]

[oslo_concurrency]

这是我的nova-compute.log：

2016-09-20 19:08:57.701 7201 INFO oslo.messaging._drivers.impl_rabbit [-] Reconnecting to AMQP server on localhost:5672

请给我一些建议，以便我能解决这个问题。。。

提前谢谢你

我在扩展nova compute estate时遇到了这个问题（尽管我没有使用Devstack）

在我新创建的计算服务器中，在/var/log/nova/nova-compute.log中可以看到以下内容：-

2017-11-14 11:40:53.287 52408奥斯陆消息错误。127.0.0.1:5672上的AMQP服务器无法访问[req-adfd6dc7-fe8c-4de5-8401-58d325c3b4a8----][be6e0302-dfc8-4512-8b48-0d824fc6ea14]。1秒钟后再试一次。客户端端口：无

解决办法很简单。我检查了/var/log/sysinfo（我在Redhat系统上运行ubuntu；/var/log/messages），可以看到以下几行：-
