[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 openstack-glance-api openstack-glance-registry |
