RabbitMQ creating queues and bindings from command line

Tags:

rabbitmq

If I have RabbitMQ installed on my machine, is there a way to create a message queue from the command line and bind it to a certain exchange without using a client?

I think it is not possible, but I want to be sure.

How do you bind a queue in RabbitMQ?

The first queue is bound with binding key orange, and the second has two bindings, one with binding key black and the other one with green. In such a setup a message published to the exchange with a routing key orange will be routed to queue Q1. Messages with a routing key of black or green will go to Q2.

Does RabbitMQ automatically create queues?

Summary:

Other answers are good alternatives to what was asked for. Below are commands you can use from the command line.

First, do all the necessary prep work, e.g. install rabbit, rabbitmqadmin, and rabbitctl. The idea is to use commands from rabbitmqctl and rabbitmqadmin. You can see some command examples: https://www.rabbitmq.com/management-cli.html

Example Commands/Setup:

The following commands should give you the majority if not all of what you need:

# Get the cli and make it available to use.
wget http://127.0.0.1:15672/cli/rabbitmqadmin
chmod +x rabbitmqadmin
mv rabbitmqadmin /etc/rabbitmq

Add a user and permissions

rabbitmqctl add_user testuser testpassword
rabbitmqctl set_user_tags testuser administrator
rabbitmqctl set_permissions -p / testuser ".*" ".*" ".*"

Make a virtual host and Set Permissions

rabbitmqctl add_vhost Some_Virtual_Host
rabbitmqctl set_permissions -p Some_Virtual_Host guest ".*" ".*" ".*"

Make an Exchange

./rabbitmqadmin declare exchange --vhost=Some_Virtual_Host name=some_exchange type=direct

Make a Queue

./rabbitmqadmin declare queue --vhost=Some_Virtual_Host name=some_outgoing_queue durable=true

Make a Binding

./rabbitmqadmin --vhost="Some_Virtual_Host" declare binding source="some_exchange" destination_type="queue" destination="some_incoming_queue" routing_key="some_routing_key"

Alternative Way to Bind with Python

The following is an alternative to command line binding, as I've had issues with it sometimes and found the following python code to be more reliable.

#!/usr/bin/env python
import pika

rabbitmq_host = "127.0.0.1"
rabbitmq_port = 5672
rabbitmq_virtual_host = "Some_Virtual_Host"
rabbitmq_send_exchange = "some_exchange" 
rabbitmq_rcv_exchange = "some_exchange"
rabbitmq_rcv_queue = "some_incoming_queue"
rabbitmq_rcv_key = "some_routing_key"

outgoingRoutingKeys = ["outgoing_routing_key"]
outgoingQueues = ["some_outgoing_queue "]

# The binding area
credentials = pika.PlainCredentials(rabbitmq_user, rabbitmq_password)
connection = pika.BlockingConnection(pika.ConnectionParameters(rabbitmq_host, rabbitmq_port, rabbitmq_virtual_host, credentials))
channel = connection.channel()
channel.queue_bind(exchange=rabbitmq_rcv_exchange, queue=rabbitmq_rcv_queue, routing_key=rabbitmq_rcv_key)

for index in range(len(outgoingRoutingKeys)):
    channel.queue_bind(exchange=rabbitmq_send_exchange, queue=outgoingQueues[index], routing_key=outgoingRoutingKeys[index])

The above can be run as part of a script using python. Notice I put the outgoing stuff into arrays, which will allow you to iterate through them. This should make things easy for deploys.

Last Thoughts

I think the above should get you moving in the right direction, use google if any specific commands don't make sense or read more with rabbitmqadmin help subcommands. I tried to use variables that explain themselves. Good luck :)

Install the RabbitMQ management plugin. It comes with a command line tool which you can use to configure all of your queues/exchanges/etc.

Maybe a little late to the party but I've done so using CURL.

For queues:

curl -i -u RABBITUSER:RABBITPASSWORD -H "content-type:application/json" \
-XPUT -d'{"durable":true}' \
http://192.168.99.100:15672/api/queues/%2f/QUEUENAME

And for bindings

curl -i -u RABBITUSER:RABBITPASSWORD -H "content-type:application/json" \
-XPOST -d"{\"routing_key\":\"QUEUENAME\"}" \
http://192.168.99.100:15672/api/bindings/%2f/e/EXCHANGENAME/q/QUEUENAME

Note 192.168.99.100:15672 points to my RMQ Management

Create Exchange:

rabbitmqadmin -u {user} -p {password} -V {vhost} declare exchange name={name} type={type}

Create Queue:

rabbitmqadmin -u {user} -p {password} -V {vhost} declare queue name={name}

Bind Queue to Exchange:

rabbitmqadmin -u {user} -p {password} -V {vhost} declare binding source={Exchange} destination={queue}

If you are using Linux Debian, there's a package called "amqp-tools". Install it with

apt-get install amqp-tools

You can then use command line such as amqp-publish to send messages to your queue

amqp-publish -e exchange_name -b "your message"

Then you can collect message(s) from the queue using

amqp-get -q queue_name

or

amqp-consume -q queue_name

There are also (command line) examples from rabbitmq-c package / library. After you build it, you can send messages through command line such as

amqp_sendstring localhost 5672 amq.direct test "hello world"

Have fun ...

rabbitmqctl, the provided command line interface, doesn't expose the ability to create a queue and bind it.

It, however, is quite trivial to do it with a quick script though, and the RabbitMQ getting started guide shows several examples of it, both on the publisher as well as the consumer side.

#do some work to connect
#do some work to open a channel
channel.queue_declare(queue='helloworld')

I'm glossing over connecting, but it's a literal one liner to create a queue. The operation is also idempotent, meaning you can include the statement in a script and be safe, knowing that it won't keep recreating the queue or blowing out an existing one of the same name.

Create RabbitMq Exchange, Queue and Bindings dynamically from CLI on Windows

I already had a RabbitMQ Server installed and running with multiple queue and exchange and now wanted to create it on the fly from command line. I know it is an old question but I thought giving out this information will be helpful.

Following is what I did:

Setup

  1. Downloaded and installed Python 2.6.6-201008-24 Windows x86-64 MSI installer , any version of python greater than 2.X but not 3.X
  2. Download RabbitMqAdmin: RabbitMq Web User Interface has a link Command Line which navigates to http://server-name:15672/cli/ (server-name: server on which rabbitmq is installed) alternatively,use the above url and save the file as rabbitmqadmin.exe in the python exe location

eg: C:\Python26\ C:\Python26\python C:\Python26\rabbitmqadmin.exe

Code:in a batch file used the below commands

  1. Create exchange:

    c:\python26\python.exe rabbitmqadmin.exe declare exchange name=ExchangeName1 type=topic durable=true

  2. Create queue:

    c:\python26\python.exe rabbitmqadmin.exe declare queue name=NameofQueue1 durable=true

  3. Create binding:

    c:\python26\python.exe rabbitmqadmin.exe declare binding source=ExchangeName1 destination_type=queue destination=NameofQueue1 routing_key=RoutingKey1

by executing rabbitmqadmin.exe -help -subcommands it lists all the available commands

eg: c:\python26\python.exe rabbitmqadmin.exe -help -subcommands
