How to install RabbitMQ in Fedora 35

In this guide we will explore how to install the latest release of RabbitMQ in Fedora 35 server or Workstation

RabbitMQ is an open source message broker software that implements the Advanced Message Queuing Protocol (AMQP). RabbitMQ works by receiving messages from publishers (applications that publish them) and routes them to consumers (applications that process them).

1. Updating the system

Before proceeding, ensure that the server packages are up to date. Use this command to achieve that:

sudo dnf -y update

2. Adding PackageCloud Yum Repository

The RabbitMQ package is distributed via Yum repositories on PackageCloud. Install the PackageCloud Yum repository using this command:

curl -s https://packagecloud.io/install/repositories/rabbitmq/rabbitmq-server/script.rpm.sh | sudo bash

This is the output on my server:

$ curl -s https://packagecloud.io/install/repositories/rabbitmq/rabbitmq-server/script.rpm.sh | sudo bash

3. Installing Erlang

RabbitMQ requires Erlang/OTP to run. The rabbitmq/erlang-rpm project provides a zero dependency 64-bit Erlang RPM package that provides just enough to run RabbitMQ. Get the latest from the releases here https://github.com/rabbitmq/erlang-rpm/releases.

curl -LO -C - https://github.com/rabbitmq/erlang-rpm/releases/download/v24.1.4/erlang-24.1.4-1.el8.x86_64.rpm

Then install the downloaded file

sudo dnf install ./erlang-24.1.4-1.el8.x86_64.rpm

This is the output on my server

$ sudo dnf install ./erlang-24.1.4-1.el8.x86_64.rpm

5. Starting and enabling rabbitmq-server service

Start the service

sudo systemctl start rabbitmq-server

Then check the status to confirm its running

$ sudo systemctl status rabbitmq-server
● rabbitmq-server.service - RabbitMQ broker
     Loaded: loaded (/usr/lib/systemd/system/rabbitmq-server.service; disabled; vendor preset: disabled)

Now you can enable it on boot

sudo systemctl enable rabbitmq-server

You can get status of rabbitmq internals:

$ sudo rabbitmqctl status

6. Optional: Enabling RabbitMQ Dashboard

Use the rabbitmq-plugins enable command to enable the management dashboard:

$ sudo rabbitmq-plugins enable rabbitmq_management
Enabling plugins on node rabbit@cloudsrv:
rabbitmq_management
The following plugins have been configured:
  rabbitmq_management
  rabbitmq_management_agent
  rabbitmq_web_dispatch
Applying plugin configuration to rabbit@cloudsrv...
The following plugins have been enabled:
  rabbitmq_management
  rabbitmq_management_agent
  rabbitmq_web_dispatch

started 3 plugins.

The web service is up listening on port 15672

$ ss -tunlp | grep 15672
tcp   LISTEN 0      128          0.0.0.0:15672      0.0.0.0:*

If you have an active Firewalld service, allow ports 5672 and 15672

$ ss -tunlp | grep 15672
tcp   LISTEN 0      1024         0.0.0.0:15672      0.0.0.0:*

Access it by opening the URL <a href="https://computingforgeeks.com/" target="_blank" rel="noreferrer noopener">http://[server</a>&nbsp;IP]:15672 like http://127.0.0.1:15672

By default, the guest user exists and can connect only from localhost. You can log in with this user locally with the password “guest”

To be able to login on the network, create an admin user like below:

$ sudo rabbitmqctl add_user admin Secr3t
Adding user "admin" ...
Done. Don't forget to grant the user permissions to some virtual hosts! See 'rabbitmqctl help set_permissions' to learn more.

$ sudo rabbitmqctl set_user_tags admin administrator
Setting tags for user "admin" to [administrator] ...

Login with this admin username and the password assigned. You should see an interface similar to below:

citizix - Rabbitmq Dashboard

citizix – Rabbitmq Dashboard

To use rabbitmqadmin command line tool, copy it to your $PATH.

sudo dnf install -y mlocate
sudo updatedb
sudo cp `locate rabbitmqadmin` /usr/local/bin/rabbitmqadmin
sudo chmod +x /usr/local/bin/rabbitmqadmin

You need to have python installed and configured to run rabbitmqadmin. Use this command to ensure that python is installed:

sudo dnf install -y python3

7. Basic RabbitMQ User Management Commands

Delete User:

sudo rabbitmqctl delete_user user

Change User Password:

sudo rabbitmqctl change_password user strongpassword

Create new Virtualhost:

sudo rabbitmqctl add_vhost /my_vhost

List available Virtualhosts:

sudo rabbitmqctl list_vhosts

Delete a virtualhost:

sudo rabbitmqctl delete_vhost /myvhost

Grant user permissions for vhost:

sudo rabbitmqctl set_permissions -p /myvhost user ".*" ".*" ".*"

List vhost permissions:

sudo rabbitmqctl list_permissions -p /myvhost

To list user permissions:

rabbitmqctl list_user_permissions user

Delete user permissions:

rabbitmqctl clear_permissions -p /myvhost user
