5. Starting and enabling rabbitmq-server service

Start rabbitmq

# service rabbitmq onestart
Starting rabbitmq.

Then check the status to confirm its running

service rabbitmq onestatus

Now you can enable it on boot

# sysrc rabbitmq_enable="YES"
rabbitmq_enable:  -> YES

You can get status of rabbitmq internals:

# rabbitmqctl status

6. Optional: Enabling RabbitMQ Dashboard

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

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

set 3 plugins.
Offline change; changes will take effect at broker restart.

You need to restart the service to apply the changes

# service rabbitmq restart
Stopping rabbitmq.
Starting rabbitmq.

The web service is up listening on port 15672

Access it by opening the URL <a href="https://computingforgeeks.com/" target="_blank" rel="noreferrer noopener">http://[server</a> 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:

# 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.

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