从虚拟机无法启动(HTTP500)到rabbitMQ的错误：Error: unable to connect to node 'rabbit@linux-node1': nodedown
我的问题的起因是在看赵班长的视频中，当启动虚拟机的时候报错（由于无法上传图片，我就把错误截图内容打字出来了），报错内容如下：
Error:The server has either erred or is incapable of performing the requested operation.(HTTP 500)(Request-ID:req-0e531ab4-0a80-473b-bb90-e937865b7a65)
Error: Unable to launch instance named "demo"
然后，查看nova的api.log日志，内容如下：
...(发贴子后，在提交时告诉我不允许发送站外链接，所以这部分的内容删除掉了，这里是些日志内容)
[b]2018-06-22 19:08:25.208 2260 ERROR nova.api.openstack [req-0e531ab4-0a80-473b-bb90-e937865b7a65 84ee8ed4a5154ceb891c3f5921abfa6e ce967fbddc0b4be08718773d0b1e68bc] Caught error: Timed out waiting for a reply to message ID 060a620bbf0448d6bb05a91c6647cf7f[/b]
... (发贴子后，在提交时告诉我不允许发送站外链接，所以这部分的内容删除掉了，这里是些日志内容)
上面粗体内容，说明是等待超时了，我怀疑是消息队列是否有问题，然后就查看rabbitMQ的相关内容。
下面是rabbitMQ日志文件内容：
...
[b]=ERROR REPORT==== 22-Jun-2018::19:10:19 ===
** Connection attempt from disallowed node 'rabbitmqctl2606@linux-node1' ** [/b]
日志里有个不允许的节点
然后我执行rabbitmqctl status后，报错如下：
[root@linux-node1 ~]# rabbitmqctl status
Status of node 'rabbit@linux-node1' ...
Error: unable to connect to node 'rabbit@linux-node1': nodedown
DIAGNOSTICS
===========
nodes in question: ['rabbit@linux-node1']
hosts, their running nodes and ports:
- linux-node1: [{rabbit,60831},{rabbitmqctl2606,19038}]
current node details:
- node name: 'rabbitmqctl2606@linux-node1'
- home dir: /root
- cookie hash: FYA1RzbUK6Toom04BLiG6Q==
下面是我的hosts文件内容：
[root@linux-node1 ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
10.0.0.149 linux-node1.example.com linux-node1
我在网上查找各种引起Error: unable to connect to node 'rabbit@linux-node1': nodedown
的原因，重启rabbitMQ、卸载重装rabbitMQ均无效，始终出现这个Error错误。
现在，想请教赵班长，这个问题要如何解决呢？？
