RabbitMQ is an open source message broker software that implements the Advanced Message Queuing Protocol (AMQP) and Streaming Text Oriented Messaging Protocol, Message Queuing Telemetry Transport, and other protocols via a Plugins.

The work of a Messaging broker is to receive messages from publishers (applications that publish them) and route them to consumers (applications that process them). AMQP is a messaging protocol that enables conforming client applications to communicate with conforming messaging middleware brokers.

You can confirm if the service is configured to start on boot using the command:

$ systemctl is-enabled rabbitmq-server.service 

If it returns disabled, enable it by running:

sudo systemctl enable rabbitmq-server

Step 3: 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 UFW firewall, open both ports 5672 and 15672:

sudo ufw allow proto tcp from any to any port 5672,15672

Access it by opening the URL http://[server IP|Hostname]:15672

install rabbitmq ubuntu 18.04 dashboard min

By default, the guest user exists and can connect only from localhost. You can login 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.

Step 4: Set RabbitMQ Cluster (Optional)

If you need to achieve high availability and higher throughput, consider configuring RabbitMQ cluster on your Ubuntu 18.04 servers by following the guide below:

How to Configure RabbitMQ Cluster on Ubuntu 18.04 LTS

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
