openstack在centos7上安装与配置-折腾笔记

有一些小需求,需要搭建配置openstack服务。

物理机:Centos7 X64

一、openstack安装

详细过程见参考链接1

二、问题总结

1、新建images之后所有任务都显示正在排队,但是一直没有结束

问题猜想:rabbitmq挂了?

问题验证:

rabbitmqctl status

结果:

Error: unable to connect to node rabbit@cloud: nodedown

DIAGNOSTICS
===========

attempted to contact: [rabbit@cloud]

rabbit@cloud:
  * connected to epmd (port 4369) on cloud
  * epmd reports: node 'rabbit' not running at all
                  no other nodes on cloud
  * suggestion: start the node

current node details:
- node name: 'rabbitmq-cli-43@cloud'
- home dir: /var/lib/rabbitmq
- cookie hash: 5wXsOSwBK1y3NHOxZrkEJA==

解决方法:应该是由于hosts内没有解析cloud、cloud.claves.me域名导致的

编辑/etc/hosts,新建DNS解析后,解决!
