Inleiding
Dit document beschrijft hoe u problemen kunt oplossen wanneer u verbinding maakt met de RabbitMQ User Interface (UI).
Voorwaarden
Vereisten
Er zijn geen specifieke vereisten van toepassing op dit document.
Gebruikte componenten
De informatie in dit document is gebaseerd op 4.7.X en 4.8.X.
De informatie in dit document is gebaseerd op de apparaten in een specifieke laboratoriumomgeving. Alle apparaten die in dit document worden beschreven, hadden een opgeschoonde (standaard)configuratie. Als uw netwerk live is, moet u de potentiële impact van elke opdracht begrijpen.
Probleem
Wanneer u probeert om verbinding te maken met http://IP_address_of_AMQP:15672 via uw browser, ontvangt u een "geweigerd om verbinding te maken" fout.
Ook op RabbitMQ-console zie je dit:
[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==
Oplossing
1. Herstel de hostnaam van de virtuele machine (VM's).
2. Installeer konijn opnieuw:
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 poort 15672 op firewall:
iptables -I INPUT 1 -p tcp --dport 15672 -j ACCEPT
service iptables save
service iptables restart
Verifiëren
De verwachte productie zou zijn:
# netstat -atun | grep 15672
tcp 0 0 0.0.0.0:15672 0.0.0.0:* LISTEN
Gebruik deze opdracht van een andere VM om de connectiviteit te bevestigen:
telent IP_address_of_AMQP 15672
# rabbitmqctl status
]Status of node rabbit@haamqp2 ...

Nu zou u een webbrowser moeten kunnen openen naar http://IP_address_of_AMQP:15672 en de RabbitMQ GUI moeten kunnen lanceren. De standaardlognaam is kliqr/cliqr.
