简介
本文档介绍如何在连接到RabbitMQ用户界面(UI)时解决问题。
先决条件
要求
本文档没有任何特定的要求。
使用的组件
本文档中的信息基于4.7.X和4.8.X。
本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您使用的是真实网络，请确保您已经了解所有命令的潜在影响。
问题
当您尝试通过浏览器连接到http://IP_address_of_AMQP:15672时，您会收到“拒绝连接”错误。
此外，在RabbitMQ控制台上，您会看到：
[root@amqp ~]# rabbitmqctl status
Status of node rabbit@amqp ...
Error: unable to connect to node rabbit@amqp: nodedown
DIAGNOSTICS
===========
attempted to contact: [rabbit@amqp]
rabbit@amqp:
* connected to epmd (port 4369) on amqp
* epmd reports: node 'rabbit' not running at all
no other nodes on amqp
* suggestion: start the node
current node details:
- node name: 'rabbitmq-cli-3496@amqp'
- home dir: /var/lib/rabbitmq
- cookie hash: gsXBP8HgENjwAKcRmvMU6A==
解决方案
1.重新配置虚拟机(VM)的主机名。
- 使用新主机名更新/etc/hosts和/etc/hostname。
请勿在新主机名中使用破折号。
2.重新安装Rabbit:
rm /etc/cliqr_modules.conf
yum remove -y wxGTK-g1-2.8.12-20.e17.x86_64
chmod +x core+installer.bin
./core_installer.bin <os> <platform> rabbit
java -jar cco-installer.jar conn_broker-response.xml
3.打开防火墙上的端口15672:
iptables -I INPUT 1 -p tcp --dport 15672 -j ACCEPT
service iptables save
service iptables restart
验证
预期输出为：
# netstat -atun | grep 15672
tcp 0 0 0.0.0.0:15672 0.0.0.0:* LISTEN
从另一台VM，使用此命令确认连接：
telent IP_address_of_AMQP 15672
# rabbitmqctl status
]Status of node rabbit@haamqp2 ...

现在，您应该能够打开Web浏览器访问http://IP_address_of_AMQP:15672并启动RabbitMQ GUI。默认登录名为cliqr/cliqr。
