RabbitMQ is an open source most popular message broker software that implements the Advanced Message Queuing Protocol (AMQP). It is written in the Erlang programming language. RabbitMQ can be easily deployed in a distributed and federated configurations to meet high-scale, high-availability requirements.
In this article I will show you how to install RabbitMQ on CentOS 7.
Prerequisites
1. Needed CentOS 7 Operating system.
2. Need root access or sudo privileges.
Install RabbitMQ on CentOS 7
First of all you have to add the Erlang yum repository on your CentOS system. You can download the Erlang repository package from its official website and install it on your server like below.
Install Erlang

Now verify Erlang installation using below command.
# erl Erlang/OTP 20 [erts-9.1] [source] [64-bit] [smp:1:1] [ds:1:1:10] [async-threads:10] [hipe] [kernel-poll:false] Eshell V9.1 (abort with ^G)
Press Ctrl+c twice to exit the Erlang screen.
Install RabbitMQ Server
Next, after installing requirements now download and install RabbitMQ server.

Edit Firewall Rules
To access the the RabbitMQ remote management console you need to allow inbound TCP traffic on ports 4369, 25672, 5671, 5672, 15672, 61613, 61614, 1883, and 8883.
# firewall-cmd --zone=public --permanent --add-port=4369/tcp --add-port=25672/tcp --add-port=5671-5672/tcp --add-port=15672/tcp --add-port=61613-61614/tcp --add-port=1883/tcp --add-port=8883/tcp # firewall-cmd --reload
Now start the RabbitMQ server and enable it to start on the system boot.
# /etc/init.d/rabbitmq-server start
Starting rabbitmq-server: FAILED - check /var/log/rabbitmq/startup_{log, _err}
rabbitmq-server.
If you are getting above error, you will need to edit your /etc/hosts file as below to fix this.
# vim /etc/hosts 127.0.0.1 hostname
Save and close.
Then now start the rabbitmq service again and you will get success message like below.
# /etc/init.d/rabbitmq-server start Starting rabbitmq-server: SUCCESS rabbitmq-server.
Now you can check the RabbitMQ status using below command.
# rabbitmqctl status

Create Admin User and Password For RabbitMQ
By default rabbitmb create user and password named “guest” with password “guest”. Now create your own admin user and password for accessing the RabbitMQ server management console using bellow command.
# sudo rabbitmqctl add_user admin password # sudo rabbitmqctl set_user_tags admin administrator # sudo rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"
Setup RabbitMQ Web Management Console
You can also manage RabbitMQ using web management console. Follow the below command to enable the web management console.
# rabbitmq-plugins enable rabbitmq_management The following plugins have been enabled: mochiweb webmachine rabbitmq_web_dispatch amqp_client rabbitmq_management_agent rabbitmq_management
Applying plugin configuration to rabbit@mon… started 6 plugins.
# chown -R rabbitmq:rabbitmq /var/lib/rabbitmq/
Now open your web browser and type the below URL in browser.
http://your_server_ip_and_domain_name:15672
Use the username and password created before.
