How to install and work with RabbitMQ – Part 1

This blog is about installation and working with one of the most useful message queuing system called RabbitMQ.

Before beginning, it is important for us to know what it actually does. This is more like a server mainly used for better queuing of messages. It uses a protocol called AMQP Advanced Message Queuing Protocol which enables the data to queue in a better rate and then process them.

This RabbitMQ is built on a language which is most infamous now and its called Erlang and it is built on Open Telecom Platform Framework for clustering and failover.

Previously there was a disadvantage in using this RabbitMQ because everything has to be handled via command prompt. People who uses this server were not tech savvy to do that. Later in their version they created a management studio that enables even a layman to work better.

It is also important for us to understand that not only RabbitMQ but also apache has a similar feature of server. Apache’s distribution of queuing mechanism is called Apache Kafka. We will discuss more about the both in fore coming days.

INSTALLATION OF RABBIT-MQ:

Step 1: Install Erlang –  We need to install Erlang and its corresponding components first before installing RabbitMQ. RabbitMQ will not work if Erlang is not installed. Download the latest version of Erlang from here.

Step 2: Once the installation is done, you have to set the environment config of ERLANG_HOME. If you are using Windows 10 you don’t need to setup the environment variable. It will be automatically setup as shown below.rabbitmq-Setup

Step 3: Install the latest version of RabbitMQ from here. This installation is pretty straight forward. If the installation of the Erlang is done without any problem then this will also work as smooth as butter.

Step 4: RabbitMQ runs by default as a windows service. We don’t need to explicitly invoke it. But at this stage you will have to do everything in the command line interface. Which is a tedious task. So it is better to work with the web management console interface of this.

  • Open command line interface with Admin access.
  • Navigate to C:\Program Files (x86)\RabbitMQ Server\rabbitmq_server-3.3.4\sbin 
  • Run the command rabbitmq-plugins.bat enable rabbitmq_management to enable the plugin of web management
  • Once, the above command is done, then re-install the RabbitMQ  using following commands:
  • rabbitmq-service.bat stop
    rabbitmq-service.bat install
    rabbitmq-service.bat start
  • Note: you can remain in the same directory to perform this.

If everything works fine as shown above in the screenshot. Then you can now open the web console of the RabbitMQ. you can access the RabbitMQ using the url http://localhost:15672/ the default username and password for this console will be guest guest

Will post more POC’s integrating RabbitMQ with Mirthconnect in future posts.

Happy Integrations!!!!!
