错误提示

创建消息队列用户,用于controler和node节点连接rabbitmq的认证（关联）

[root@controller ~]# rabbitmqctl add_user openstack RABBIT_PASS
Error: unable to connect to node rabbit@localhost: nodedown

DIAGNOSTICS

attempted to contact: [rabbit@localhost]

rabbit@localhost:

• connected to epmd (port 4369) on localhost

• epmd reports node ‘rabbit’ running on port 25672

• TCP connection succeeded but Erlang distribution failed

• Hostname mismatch: node “rabbit@controller” believes its host is different. Please ensure that hostnames resolve the same way locally and on “rabbit@controller”

current node details:

• node name: ‘rabbitmq-cli-72@controller’
• home dir: /var/lib/rabbitmq
• cookie hash: PBg4z2VOVcLh7Tuei+Frgw==

报错解释：

错误:无法连接到节点rabbit@localhost: nodedown
诊断

===========
试图联系:[rabbit@localhost]
rabbit@localhost:
*连接到本地主机的epmd(端口4369)

• epmd报告节点’rabbit’在端口25672上运行
• TCP连接成功，但Erlang分发失败
  主机名不匹配:节点“rabbit@controller”认为它的主机不一样。请确保主机名在本地和“rabbit@controller”上以相同的方式解析
  当前节点的详细信息:
  -节点名称:“rabbitmq-cli-72@controller”
  —home dir:“/var/lib/rabbitmq”
  —cookie hash: PBg4z2VOVcLh7Tuei+Frgw==

解决思路：

杀死RabbitMQ
重启虚拟机 重启RabbitMQ服务

解决

[root@controller ~]# rabbitmqctl add_user openstack RABBIT_PASS
Creating user “openstack”
