by On this article we will discuss how to install RabbitMQ with Erlang/OTP 23.x on Ubuntu 20.04 LTS
Introduction
If our work is related to message brokers, there are several software options that can be selected, including Apache Kafka and RabbitMQ. Selection of the right software depends on the characteristics of the system we are building. Apache Kafka is suitable for complex streams with processing data in multi-stage pipelines while RabbitMQ is suitable for applications that need to support legacy protocols, such as STOMP, MQTT. On this article we will discuss how to install RabbitMQ on Linux Ubuntu 20.04 LTS.
RabbitMQ is an open-source message-broker software (sometimes called message-oriented middleware) that originally implemented the Advanced Message Queuing Protocol (AMQP) and has since been extended with a plug-in architecture to support Streaming Text Oriented Messaging Protocol (STOMP), MQ Telemetry Transport (MQTT), and other protocols
RabbitMQ Installation on Ubuntu Steps
We will use the lastest stable version of RabbitMQ repository for our installation tutorial. The last stable RabbitMQ version is 3.8.3 which was released on September 3, 2020. The installation will be consist of several steps as described below :
- Prerequisite
- Add RabbitMQ Repository
- Install RabbitMQ on Ubuntu
- Enable RabbitMQ Management Dasboard
Prerequisite
RabbitMQ requires Erlang programming language. We have installed the Erlang/TOP on our Ubuntu system on the previous article. Here’s the Erlang installation on Ubuntu 20.04 LTS article. Another prerequistes are : A user account with sudo or root privileges and sufficient disk for RabbitMQ binnary files.
Add RabbitMQ Repository
After prerequisite are met, the next step is to add RabbitMQ repository ot our Ubuntu system. On this step we will do :
- Install RabbitMQ signing key, we will submit the command line :
curl -fsSL https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc | sudo apt-key add - - Add Bintray repository, we will submit the command line :
sudo tee /etc/apt/sources.list.d/bintray.rabbitmq.list
< deb https://dl.bintray.com/rabbitmq/debian bionic main> EOF
ramans@otodiginet:~$ curl -fsSL https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc | sudo apt-key add - [sudo] password for ramans: OK ramans@otodiginet:~$ sudo tee /etc/apt/sources.list.d/bintray.rabbitmq.list <<EOF deb https://dl.bintray.com/rabbitmq/debian bionic main EOF deb https://dl.bintray.com/rabbitmq/debian bionic main
3.Install HTTPS transport, bu submitting command line : sudo apt-get install apt-transport-https
ramans@otodiginet:~$ sudo apt-get install apt-transport-https Reading package lists… Done Building dependency tree Reading state information… Done apt-transport-https is already the newest version (2.0.2ubuntu0.1). 0 upgraded, 0 newly installed, 0 to remove and 329 not upgraded.
Install RabbitMQ on Ubuntu
On this step, we just install RabbitMQ. Before we do the installation, it is recommended if we update our Ubuntu system first, by submitting command line : sudo apt-get update -y then we hit the installation. For the installation we will use the command line : sudo apt-get install rabbitmq-server -y --fix-missing.
ramans@otodiginet:~$ sudo apt-get install rabbitmq-server -y --fix-missing Reading package lists… Done Building dependency tree Reading state information… Done The following additional packages will be installed: socat The following NEW packages will be installed: rabbitmq-server socat 0 upgraded, 2 newly installed, 0 to remove and 329 not upgraded.

The RabbitMQ services was started up when the installation process. To ensure, we will verify the RabbitMQ service by submitting command line : sudo systemctl status rabbitmq-server.

Enable RabbitMQ Management Dasboard
To facilitate the use of RabbitMQ, a web-based dashboard has been provided, where the admin can manage everything related to the RabbitMQ application. For this purpose, we have to enable the RabbitMQ management dashboard by submitting command line : sudo rabbitmq-plugins enable rabbitmq_management.
ramans@otodiginet:~$ sudo rabbitmq-plugins enable rabbitmq_management Enabling plugins on node rabbit@otodiginet: rabbitmq_management The following plugins have been configured: rabbitmq_management rabbitmq_management_agent rabbitmq_web_dispatch Applying plugin configuration to rabbit@otodiginet… The following plugins have been enabled: rabbitmq_management rabbitmq_management_agent rabbitmq_web_dispatch started 3 plugins.
The RabbitMQ management dashboard is using port 15672, we will verify it by checking the binding port on the system. For this purpose will submit command line : netstat -an | grep 15672.
ramans@otodiginet:~$ netstat -an | grep 15672 tcp 0 0 0.0.0.0:15672 0.0.0.0:* LISTEN
The RabbitMQ management dashboard will be live at URL : http://[server_rabbitmq_ipadress]:15672. For using this dashboard we will use the username : geust and password: guest for the firstime login, so we can configure (add) another user and setting their privileges.
Conclusion
Until here, the RabbitMQ installation on Ubuntu 20.04 LTS has been done successfully. For further tutorial about RabbitMQ, we can visit RabbitMQ official tutorials website.
