root@dlp ~(keystone)#
vi /etc/glance/glance-api.conf # add to the end [oslo_messaging_notifications] driver = messagingv2 # RabbitMQ connection info transport_url = rabbit://openstack:password@10.0.0.30
root@dlp ~(keystone)#
vi /etc/glance/glance-registry.conf # add to the end [oslo_messaging_notifications] driver = messagingv2 # RabbitMQ connection info transport_url = rabbit://openstack:password@10.0.0.30 systemctl restart glance-api glance-registry |
