Now you can enable it on boot

sudo systemctl enable rabbitmq

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
/usr/lib/erlang/erts-12.1.5/bin/beam.smp: /usr/lib/libncursesw.so.6: no version information available (required by /usr/lib/erlang/erts-12.1.5/bin/beam.smp)
Enabling plugins on node [email protected]:
rabbitmq_management
The following plugins have been configured:
  rabbitmq_management
  rabbitmq_management_agent
  rabbitmq_web_dispatch
Applying plugin configuration to [email protected]
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      1024            0.0.0.0:15672      0.0.0.0:*

Access it by opening the URL http://[server_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

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
