Chapter 3. Getting started
This chapter guides you through the steps to set up your environment and run a simple messaging program.
3.1. Prerequisites
- You must complete the installation procedure for your environment.
-
You must have an AMQP 1.0 message broker listening for connections on interface
localhostand port5672. It must have anonymous access enabled. For more information, see Starting the broker. -
You must have a queue named
examples. For more information, see Creating a queue.
3.2. Running Hello World on Red Hat Enterprise Linux
The Hello World example creates a connection to the broker, sends a message containing a greeting to the examples queue, and receives it back. On success, it prints the received message to the console.
Change to the examples directory and run the helloworld.rb example.
$ cd /usr/share/proton/examples/ruby/ $ ruby helloworld.rb amqp://127.0.0.1 examples Hello World!
