Home OpenStack-Ansible Installation Guide
RabbitMQ provides the messaging broker for various OpenStack services. The OpenStack-Ansible project configures a plaintext listener on port 5672 and a SSL/TLS encrypted listener on port 5671.
Customizing the RabbitMQ deployment is done within /etc/openstack_deploy/user_variables.yml.
The OpenStack-Ansible project provides the ability to secure RabbitMQ communications with self-signed or user-provided SSL certificates. Refer to Securing services with SSL certificates for available configuration options.
SSL communication between various OpenStack services and RabbitMQ is controlled via the Ansible variable rabbitmq_use_ssl:
rabbitmq_use_ssl: true
Setting this variable to true will adjust the RabbitMQ port to 5671 (the default SSL/TLS listener port) and enable SSL connectivity between each OpenStack service and RabbitMQ.
Setting this variable to false will disable SSL encryption between OpenStack services and RabbitMQ. The plaintext port for RabbitMQ, 5672, will be used for all services.
