Introduction
This document describes how to resolve issues when you connect to the RabbitMQ User Interface (UI).
Prerequisites
Requirements
There are no specific requirements for this document.
Components Used
The information in this document is based on 4.7.X and 4.8.X.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
Problem
When you try to connect to http://IP_address_of_AMQP:15672 via your browser, you receive a "refused to connect" error.
Also on RabbitMQ console, this is what you see:
[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==
Solution
1. Reconfigure the Virtual Machine's (VM's) hostname.
2. Reinstall Rabbit:
rm /etc/cliqr_modules.conf
yum remove -y wxGTK-g1-2.8.12-20.e17.x86_64
- Download core_installer.bin:
chmod +x core+installer.bin
./core_installer.bin <os> <platform> rabbit
java -jar cco-installer.jar conn_broker-response.xml
3. Open port 15672 on firewall:
iptables -I INPUT 1 -p tcp --dport 15672 -j ACCEPT
service iptables save
service iptables restart
Verify
Expected output would be:
# netstat -atun | grep 15672
tcp 0 0 0.0.0.0:15672 0.0.0.0:* LISTEN
From another VM, make use of this command to confirm connectivity:
telent IP_address_of_AMQP 15672
# rabbitmqctl status
]Status of node rabbit@haamqp2 ...

Now you should be able to open a web browser to http://IP_address_of_AMQP:15672 and launch the RabbitMQ GUI. The default login is cliqr/cliqr.
