* RabbitMQ Troubleshooting

Check if RabbitMQ is running or not:

rabbitmqctl status

rabbitmqctl environment

Check if any crash file exists here:

cd /var/lib/rabbitmq/

Restart the RabbitMQ service on the first controller node:

service rabbitmq-server stop

service rabbitmq-server start

If the service refuses to stop, then run the pkill command to stop the service, then restart the service:

pkill -KILL -u rabbitmq

service rabbitmq-server start

Verify RabbitMQ processes are running:

ps -ef | grep rabbitmq

rabbitmqctl list_queues

rabbitmqctl list_queues 2>&1 | grep -i error

If there are errors, run the cluster_status command to make sure there are no partitions:

rabbitmqctl cluster_status
