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), Message Queuing Telemetry Transport (MQTT), and other protocols. It is written in the Erlang programming language and is built on the Open Telecom Platform framework for clustering and failover.
RabbitMQ is lightweight and easy to deploy on premises and in the cloud. It supports multiple messaging protocols. RabbitMQ can be deployed in distributed and federated configurations to meet high-scale, high-availability requirements.
Step 1: Install EPEL Repo
dnf -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
Step 2: Install Erlang
dnf -y install wget
wget https://github.com/rabbitmq/erlang-rpm/releases/download/v21.3.8.6/erlang-21.3.8.6-1.el7.x86_64.rpm
dnf install -y erlang-21.3.8.6-1.el7.x86_64.rpm
Verify your installation of Erlang:
erl
Press Ctrl+C twice to exit from Erlang shell.
Step 3: Add RabbitMQ Repository
Create a Repository file for RabbitMQ using below command
vi /etc/yum.repos.d/rabbitmq-server.repo
now add below lines in that file
[rabbitmq-server] name=rabbitmq-server baseurl=https://packagecloud.io/rabbitmq/rabbitmq-server/el/7/$basearch repo_gpgcheck=1 gpgcheck=0 enabled=1 gpgkey=https://packagecloud.io/rabbitmq/rabbitmq-server/gpgkey sslverify=1 sslcacert=/etc/pki/tls/certs/ca-bundle.crt metadata_expire=300
save changes to file and exit.
Step 4: Install RabbitMQ on RHEL 8 and CentOS 8
Run following commands to install RabbitMQ Server:
dnf makecache -y --disablerepo='*' --enablerepo='rabbitmq-server' dnf install -y rabbitmq-server
You can see package details by running below command.
rpm -qi rabbitmq-server
Step 5: Configure firewall and Start RabbitMQ
We have to allow inbound TCP traffic on ports 4369, 25672, 5671, 5672, 15672, 61613, 61614, 1883, and 8883
Run following commands to add ports in firewalld
firewall-cmd --zone=public --permanent --add-port={4369,25672,5671,5672,15672,61613,61614,1883,8883}/tcp
firewall-cmd --reload
Step 5: Enable and use the RabbitMQ management console
Start the RabbitMQ server and enable it on system boot:
systemctl start rabbitmq-server.service systemctl enable rabbitmq-server.service
Use following command if you want to check RabbitMQ Service status
systemctl status rabbitmq-server.service rabbitmqctl status
If you want to monitor RabbitMQ server processes from a web browser, enable RabbitMQ management console using below commands.
rabbitmq-plugins enable rabbitmq_management chown -R rabbitmq:rabbitmq /var/lib/rabbitmq/
Setup an administrator user account in order to access the RabbitMQ server management console by running following commands.
Note: replace “admin” with your desired username and replace “mypassword” with your desired password you want to set, in below commands.
rabbitmqctl add_user admin mypassword rabbitmqctl set_user_tags admin administrator rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"
In order to change user password you can use below command:
rabbitmqctl change_password user-name user-password
To delete a user use below command:
rabbitmqctl delete_user user-name
Step 6: Access RabbitMQ Web Managemnet Console:
Open your web browser and visit following URL:
http://YOUR-SERVER-IP:15672
You will see following login page, enter your login details to access console.
Once you enter your login details you will see below page on your browser.
Now You can see connections list, check channels, exchange and create a new queue or delete existing queues from the console.
