RabbitMQ is a message broker, the core principle: send messages, receive messages. RabbitMQ is mainly used for decoupling between components, and the message sender does not need to know the existence of the message consumer, and vice versa. RabbitMQ is used by almost all modules in OpenStack.

RabbitMQ can be managed through HTTP-based API, browser-based UI and CLI. This article introduces the most intuitive way: browser-based UI

1. Add user

Root@openstack-controller:~# rabbitmqctl add_user admin adminCreating user "admin"...

two。 Set the user role to administrator

Root@openstack-controller:~# rabbitmqctl set_user_tags admin administratorSetting tags for user "admin" to [administrator]...

3. Permission setting

Root@openstack-controller:~# rabbitmqctl set_permissions-p / admin ". *" Setting permissions for user "admin" in vhost "/".

4. Install the RabbitMQWeb Management snap-in

Root@openstack-controller:~# rabbitmq-plugins enable rabbitmq_managementThe following plugins have been enabled: mochiweb webmachine rabbitmq_web_dispatch amqp_client rabbitmq_management_agent rabbitmq_managementApplying plugin configuration to rabbit@openstack-controller... Started 6 plugins.

5. Plug-in View

Root@openstack-controller:~# rabbitmq-plugins list

6. Log in to web
