Create vHost on Windows RabbitMQ node using command line

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 :)

Hostnames are case-insensitives when you are trying to resolve them. For example, LOCALHOST and localhost are the same host.

However, when Erlang constructs the name of a node (eg. rabbit@<hostname> in the case of RabbitMQ), this name is case-sensitive. So rabbit@LOCALHOST and rabbit@localhost are two different node names, even if they run on the same host.

Recently, we (the RabbitMQ team) found out that, on Windows, the node name constructed for RabbitMQ was inconsistent. Therefore, sometimes, RabbitMQ started as a Windows service could be named rabbit@MYHOST but rabbitmqctl would try to reach rabbit@myhost and fail.

Since RabbitMQ 3.6.0, the node name should be consistent.
