Checklist

Before installation please check the following checklist provided by RabbitMQ: https://www.rabbitmq.com/production-checklist.html. Even when not installing RabbitMQ for a production environment, the following things need to be taken into account:

• Memory: Nodes hosting RabbitMQ should have at least 128MB of memory available at all times
• Memory: RabbitMQ will not accept any new messages when it detects that it's using more than 40% of the available memory
• Disk free space limit: The default limit for RabbitMQ to block all publishers is 50MB, this is low and should be changed to a more sensible value (follow the link below)

• 
  
• File handles limit: Make sure your environment allows for at least 50K open file descriptors for effective RabbitMQ user, including in development environments.

• Users: Delete the default user (guest). Default user only can connect from localhost by default, because it has well-known credentials
  

Downloading and installing RabbitMQ

Download and install RabbitMQ using the 

Terminology

• Exchange: An exchange is a very simple thing. On one side it receives messages from producers and the other side it pushes them to queues.
• Queue: They store messages that are consumed by applications.
• Message: An item that is put on the queue.Producer: Producing means nothing more than sending. A program that sends messages is a producer.
• Consumer: Consuming has a similar meaning to receiving. A consumer is a program that mostly waits to receive messages.

How to setup the queue

At this moment the only supported Queue is RabbitMQ. First you need to download the rabbitmq-server-3.6.14 from here, please choose the correct version for your operating system.

After RabbitMQ is installed we need to activate the management-plugin to be able to access the management user interface of RabbitMQ.so we can access RabbitMQ via a web interface. This is described in this article: https://www.rabbitmq.com/management.html, of which the main steps are outlined below:

1. Go to the /sbin folder of the installation folder of RabbitMQ  and open a command prompt

2. Enable the management plugin that is included with RabbitMQ server;
   run 'Open a command prompt and run rabbitmq-plugins enable rabbitmq_management' from the command prompt

3. The RabbitMQ dashboard should now be accessible through http://localhost:15672, default user is 'guest' with password 'guest'

   1. Info
      Be aware that by default, the guest user can only login from localhost

   2. add a new user so you can remove the guest user. please see: https://www.rabbitmq.com/access-control.html
