How do I delete all messages from a single queue using the CLI?

Question

you can directly run this command

sudo rabbitmqctl purge_queue queue_name

rabbitmqadmin is the perfect tool for this

rabbitmqadmin purge queue name=name_of_the_queue_to_be_purged

RabbitMQ has 2 things under queue

1. Delete
2. Purge

Delete - will delete the queue

Purge - This will empty the queue (meaning removes messages from the queue but queue still exists)

To purge queue you can use following command (more information in API doc):

curl -i -u guest:guest -XDELETE http://localhost:15672/api/queues/vhost_name/queue_name/contents

RabbitMQ implements the Advanced Message Queuing Protocol (AMQP) so you can use generic tools for stuff like this.

On Debian/Ubuntu or similar system, do:

sudo apt-get install amqp-tools
amqp-delete-queue -q celery  # where celery is the name of the queue to delete

IMPORTANT NOTE: This will delete all users and config.

ALERT !!

ALERT !!

I don't suggest this answer until unless you want to delete data from all of the queues, including users and configs. Just Reset it !!!

rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl start_app

I guess its late but for others reference, this can be done with pika

import pika
host_ip = #host ip
channel = pika.BlockingConnection(pika.ConnectionParameters(host_ip,
                                                        5672,
                                                        "/",
credentials=pika.PlainCredentials("username","pwd"))).channel()
print "deleting queue..", channel.queue_delete(queue=queue_name)
