I’ll take you through the installation of RabbitMQ on CentOS 7 / Fedora 29 / Fedora 28.

RabbitMQ is an open source message broker software that implements the Advanced Message Queuing Protocol (AMQP).

It receives messages from publishers (applications that publish them) and routes them to consumers (applications that process them).

Follow the steps below to install RabbitMQ on Fedora 29 / Fedora 28.

Step 1: Install Erlang
Before installing RabbitMQ, you must install a supported version of Erlang/OTP. The version of Erlang package available on EPEL repository should be sufficient.

sudo dnf -y install erlang
Confirm installation by running the erlcommand:

$ erl
Erlang/OTP 20 [erts-] [source] [64-bit] [smp:1:1] [ds:1:1:10] [async-threads:10] [hipe] [kernel-poll:false]

Eshell V9.3.3.3 (abort with ^G)
Step 2: Add PackageCloud Yum Repository
A Yum repository with RabbitMQ packages is available from PackageCloud.

Create a new Repository file for RabbitMQ.

sudo vim /etc/yum.repos.d/rabbitmq_rabbitmq-server.repo




Step 3: Install RabbitMQ on Fedora 29 / Fedora 28
The last step is the actual installation of RabbitMQ:

sudo dnf makecache -y –disablerepo=’*’ –enablerepo=’rabbitmq_rabbitmq-server’
sudo dnf -y install rabbitmq-server
Confirm version of RabbitMQ installed:

$ rpm -qi rabbitmq-server

Step 4: Start RabbitMQ Service
Now that you have RabbitMQ installed on your Fedora, start and enable the service to start on system boot.

sudo systemctl start rabbitmq-server
sudo systemctl enable rabbitmq-server

Step 5: Enable the RabbitMQ Management Dashboard (Optional)
You can optionally enable the RabbitMQ Management Web dashboard for easy management.

sudo rabbitmq-plugins enable rabbitmq_management
The Web service should be listening on TCP port 15672

ss -tunelp | grep 15672

tcp LISTEN 0 128* users:((“beam.smp”,pid=9525,fd=71)) uid:111 ino:39934 sk:9 <->
If you have an active Firewalld service, allow ports 5672 and 15672

sudo firewall-cmd –add-port={5672,15672}/tcp –permanent

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:

rabbitmqctl add_user admin StrongPassword
rabbitmqctl set_user_tags admin administrator
Login with this admin username and the password assigned.

RabbitMQ User Management Commands
Delete User:

rabbitmqctl delete_user user
Change User Password:

rabbitmqctl change_password user strongpassword
Create new Virtualhost:

rabbitmqctl add_vhost /my_vhost
List available Virtualhosts:

rabbitmqctl list_vhosts
Delete a virtualhost:

rabbitmqctl delete_vhost /myvhost
Grant user permissions for vhost:

rabbitmqctl set_permissions -p /myvhost user “.” “.” “.*”
List vhost permissions:

rabbitmqctl list_permissions -p /myvhost
To list user permissions:

rabbitmqctl list_user_permissions user
Delete user permissions:

rabbitmqctl clear_permissions -p /myvhost user
The next article to read is:

sudo firewall-cmd –reload
Access it by opening the URL http://[server IP|Hostname]:15672
