@Chris, Thanks for replying. When I tried to configure placement-api, I met following problems, AH01630: client denied by server configuration: /usr/bin/nova-placement-api I will read the links you pointed out.

As placement-api is required since Ocata, is there any detailed document about how to install and configure placement-api? There are two different things which might be useful to you. Some nova "in-tree" docs about placement: https://docs.openstack.org/developer/nova/placement.html https://docs.openstack.org/developer/nova/placement_dev.html and some in progress documents about installing placement: https://review.openstack.org/#/c/438328/ That latter has some errors that are in the process of being fixed, so make sure you read the associated comments. __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: OpenStack-dev-request at lists.openstack.org?subject:unsubscribe<mailto:OpenStack-dev-request at lists.openstack.org?subject:unsubscribe> http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev -------------- next part -------------- An HTML attachment was scrubbed...
