Chapter 3. Getting started
This chapter guides you through a simple exercise to help you get started using AMQ Python.
3.1. Preparing the broker
The example programs require a running broker with a queue named examples. Follow these steps to define the queue and start the broker:
Procedure
- Install the broker.
- Create a broker instance. Enable anonymous access.
Start the broker instance and check the console for any critical errors logged during startup.
$ <broker-instance-dir>/bin/artemis run ... 14:43:20,158 INFO [org.apache.activemq.artemis.integration.bootstrap] AMQ101000: Starting ActiveMQ Artemis Server ... 15:01:39,686 INFO [org.apache.activemq.artemis.core.server] AMQ221020: Started Acceptor at 0.0.0.0:5672 for protocols [AMQP] ... 15:01:39,691 INFO [org.apache.activemq.artemis.core.server] AMQ221007: Server is now live
Use the
artemis queuecommand to create a queue calledexamples.<broker-instance-dir>/bin/artemis queue create --name examples --auto-create-address --anycast
You are prompted to answer a series of questions. For yes or no questions, type
N. Otherwise, press Enter to accept the default value.
3.2. Running Hello World
The Hello World example sends a message to the examples queue on the broker and then fetches it back. On success it prints Hello World! to the console.
Using a new terminal window, change directory to the AMQ Python examples directory and run the helloworld.py example.
$ cd /usr/share/proton-0.24.0/examples/python/ $ python helloworld.py Hello World!
