In this tutorial we will show you how to install and configuration of RabbitMQ on your CentOS 7 server. For those of you who didn’t know, RabbitMQ is open source message broker software (sometimes called message-oriented middleware) that implements the Advanced Message Queuing Protocol (AMQP). The RabbitMQ server is written in the Erlang programming language and is built on the Open Telecom Platform framework for clustering and failover. Client libraries to interface with the broker are available for all major programming languages.
This article assumes you have at least basic knowledge of linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo’ to the commands to get root privileges. I will show you through the step by step installation RabbitMQ on a CentOS 7 server.
Install RabbitMQ in CentOS 7
Step 1. First let’s start by ensuring your system is up-to-date.
yum -y update
Step 2. Installing Erlang.
Install Erlang using command:
rpm -Uvh erlang-solutions-1.0-1.noarch.rpm
yum install erlang
Step 3. Installing RabbitMQ.
First thing to do is to go to RabbitMQ’s download page and download the latest stable version of RabbitMQ, At the moment of writing this article it is version 3.6.1:
rpm --import https://www.rabbitmq.com/rabbitmq-signing-key-public.asc
Installing RabbitMQ and related packages is now as simple as running just one command:
yum install rabbitmq-server-3.6.1-1.noarch.rpm
To start, stop, restart and check the RabbitMQ status, use the following:
# To start enable boot service:
systemctl enable rabbitmq-server
# To start the service:
systemctl start rabbitmq-server
# To stop the service:
systemctl stop rabbitmq-server
# To restart the service:
systemctl restart rabbitmq-server
# To check the status:
systemctl status rabbitmq-server
Step 4. Configuring SELinux and Firewall.
We must allow the following ports via SELinux, and Firewall in order to access RabbitMQ remote management console from the remote systems:
firewall-cmd --permanent --add-port=4369/tcp
firewall-cmd --permanent --add-port=25672/tcp
firewall-cmd --permanent --add-port=5671-5672/tcp
firewall-cmd --permanent --add-port=15672/tcp
firewall-cmd --permanent --add-port=61613-61614/tcp
firewall-cmd --permanent --add-port=8883/tcp
setsebool -P nis_enabled 1
Step 5. Access RabbitMQ management console.
RabbitMQ management console will allow you to monitor the server processes via a web browser:
rabbitmq-plugins enable rabbitmq_management
chown -R rabbitmq:rabbitmq /var/lib/rabbitmq/
RabbitMQ will be available on HTTP port 15672 by default. Open your favorite browser and navigate to http://yourdomain.com:15672 or http://server-ip:15672 and complete the required the steps to finish the installation.
