Installation of RabbitMQ

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 installation guides: https://www.rabbitmq.com/download.html.

After RabbitMQ is installed we need to activate the management-plugin 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. Open a command prompt and run rabbitmq-plugins enable rabbitmq_management

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

   1. 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
