RabbitMQ is an open-source message-broker software built around AMQP protocol. In this guide, you will see how to install RabbitMQ server on CentOS 8.

    What is RabbitMQ?:

    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.

    The RabbitMQ server program 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 including Java, Erlang and .NET Framework. (Source: Wikipedia)

    The RabbitMQ source code is available on RabbitMQ GitHub Repository and it is distributed under Mozilla Public License.

    Update Your Linux Server:

    Use a ssh client to connect with rabbitmq-01.centlinux.com server as Linux root user.

    Update software packages in your Linux server to the latest stable releases by using dnf command.

    You may read our previous article, if you want to completely upgrade CentOS 7 to CentOS 8 operating system.

    [root@rabbitmq-01 ~]# dnf update -y ... Installed: centos-linux-release-8.3-1.2011.el8.noarch centos-linux-repos-8-2.el8.noarch crypto-policies-scripts-20200713-1.git51d1222.el8.noarch kernel-4.18.0-240.1.1.el8_3.x86_64 kernel-core-4.18.0-240.1.1.el8_3.x86_64 kernel-modules-4.18.0-240.1.1.el8_3.x86_64 libmodulemd-2.9.4-2.el8.x86_64 memstrack-0.1.11-1.el8.x86_64 Removed: kernel-4.18.0-193.14.2.el8_2.x86_64 kernel-core-4.18.0-193.14.2.el8_2.x86_64 kernel-modules-4.18.0-193.14.2.el8_2.x86_64 Complete!

    Check the Linux operating system and Kernel version of the virtual machine in use here.

    Install EPEL Yum Repository on Linux Server:

    Some of the required software packages by RabbitMQ server are available in EPEL (Extra Packages for Enterprise Linux) yum repository.

    Therefore, you are required to enable/install EPEL yum repository on your Linux server before installing RabbitMQ.

    [root@rabbitmq-01 ~]# dnf install -y epel-release Last metadata expiration check: 0:01:41 ago on Wed 23 Dec 2020 10:43:32 PM PKT.

    Install RabbitMQ Official Yum Repository on Linux Server:

    To install a latest version of RabbitMQ server, you can either compile the source code for your preferred Linux distro, or you can add the RabbitMQ official yum repository to install RabbitMQ software from pre-compiled RPM packages.

    RabbitMQ software provides a bash script for automated installation of their official yum repository.

    Execute the following command to install RabbitMQ yum repository on your Linux server.

    [root@rabbitmq-01 ~]# curl -s https://packagecloud.io/install/repositories/rabbitmq/rabbitmq-server/script.rpm.sh | sudo bash Detected operating system as centos/8. Checking for curl...

    Build cache for newly install yum repositories.

    Install RabbitMQ Server on CentOS 8:

    Now, you can easily install RabbitMQ server by using a dnf command. All the dependencies will be resolved automatically because you have already setup the EPEL yum repository on your Linux server.

    Install RabbitMQ Managment UI on CentOS 8:

    Although RabbitMQ software contains sufficient CLI (command line) tools for administration of RabbitMQ server.

    But you can optionally install the RabbitMQ management UI to perform GUI based administration.

    Execute following command to install RabbitMQ Management UI on your Linux server.

    [root@rabbitmq-01 ~]# rabbitmq-plugins enable rabbitmq_management Enabling plugins on node rabbit@rabbitmq-01: rabbitmq_management The following plugins have been configured: rabbitmq_management rabbitmq_management_agent rabbitmq_web_dispatch Applying plugin configuration to rabbit@rabbitmq-01... The following plugins have been enabled: rabbitmq_management rabbitmq_management_agent rabbitmq_web_dispatch started 3 plugins.

    Verify that the RabbitMQ Management UI service is running on default port 15672.

    [root@rabbitmq-01 ~]# ss -tulpn | grep 15672 tcp LISTEN 0 128 0.0.0.0:15672 0.0.0.0:* users:(("beam.smp",pid=2949,fd=98))

    To allow incoming traffic to RabbitMQ Management UI, you are required to allow the default service port 15672/tcp in Linux firewall.

    Further, RabbitMQ uses port 5672/tcp for AMQP protocol based queues. Therefore, you should also enable it in the Linux Firewall.

    Execute the following command to allow required ports in Linux firewall.

    [root@rabbitmq-01 ~]# firewall-cmd --permanent --add-port={5672,15672}/tcp success [root@rabbitmq-01 ~]# firewall-cmd --reload success

     

    Create Admin User for RabbitMQ Management UI:

    RabbitMQ software shipped with a default user guest with password guest. This guest user has administrative privileges but it can only be login to RabbitMQ server from localhost.

    Therefore, we need to create another admin user to access RabbitMQ Management UI remotely.

    First, check the already available users on RabbitMQ server.

    [root@rabbitmq-01 ~]# rabbitmqctl list_users Listing users ... user tags guest [administrator]

    Now, execute following command at Linux command line to create a new user for administration of RabbitMQ server.

    [root@rabbitmq-01 ~]# rabbitmqctl add_user admin Str0ngP@ssw0rd Adding user "admin" ... [root@rabbitmq-01 ~]# rabbitmqctl set_user_tags admin administrator Setting tags for user "admin" to [administrator] ...

    Open URL http://rabbitmq-01.centlinux.com:15672/ in a web browser.

    01-install-rabbitmq-server-on-centos-8-login

    Login as admin user that you have created in previous steps.

    02-install-rabbitmq-server-on-centos-8-dashboard

    After successful login, you may reach at the dashboard of RabbitMQ Management UI. You can perform complete administration of your RabbitMQ server from here.

    We strongly recommend that you should buy and read RabbitMQ in Depth by Manning Publications to grow your knowledge in this area and to use the RabbitMQ server for your applications.

     

    Conclusion:

    In this guide, you have successfully installed RabbitMQ server on CentOS 8.
