rabbiit报错处理

一、ping不同download.yunwei.edu

　　内网服务地址必须在前面　

[root@localhost ~]# vim /etc/resolv.conf
# Generated by NetworkManager
nameserver 192.168.254.251
nameserver 223.5.5.5       

二、无法连接到主机

[root@localhost ~]# rabbitmqctl change_password guest admin
Error: unable to connect to node rabbit@localhost: nodedown

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

attempted to contact: [rabbit@localhost]

rabbit@localhost:
  * connected to epmd (port ) on localhost
  * epmd reports node 'rabbit' running on port
  * TCP connection succeeded but Erlang distribution failed
  * suggestion: hostname mismatch?
  * suggestion: is the cookie set correctly?
  * suggestion: is the Erlang distribution using TLS?

current node details:
- node name: 'rabbitmq-cli-35@jam0'
- home dir: /var/lib/rabbitmq
- cookie hash: f3vStYt4wn/ej6MSG0MD7A==

　　碰到这种情况可能是主机名没有修改过来，登出后重新登入即可

[root@jam0 ~]# rabbitmqctl change_password guest admin
Changing password for user "guest" ...

三、节点无法加入到集群中

先启动节点 ：rabbitmqctl start_app

再删除/var/lib/rabbitmq/下的文件

重启rabbitmq服务：systemctl restart rabbitmq-server.service

再次发送/etc/rabbitmq/rabbitmq-env.conf 到节点，并进行修改

重启rabbitmq服务
