RabbitMQ, a lightweight open-source message broker, can be installed on Ubuntu 16.04, 17.10, and 18.04 by first installing Erlang/OTP, as RabbitMQ requires this to run. Once both are installed, user can enable RabbitMQ to start upon server boot up and activate RabbitMQ Web Console for easier management. Note that for Ubuntu 18.04, users have to manually install Erlang/OTP and RabbitMQ at the time of writing.
