Hello. I am here again,Last time I have try to install Ocata on Cenots 7,get placement API problem and fix it at last. But I stil get placement API try to install Ocata on Ubuntu.
I have apt-get install nova-placement-api and apache2 site seems work.
Listen 8778
<virtualhost *:8778="">
WSGIScriptAlias / /usr/bin/nova-placement-api
Seems I should create service endbpoint like this:
openstack service create --name placement --description "OpenStack Placement" placement
openstack endpoint create --region RegionOne placement public http://controller:8778
openstack endpoint create --region RegionOne placement admin http://controller:8778
openstack endpoint create --region RegionOne placement internal http://controller:8778

But when I restart nova service, I get the follow error:
2017-03-08 15:16:00.930 22919 WARNING nova.scheduler.client.report [req-70d8f814-a975-4fb4-adf2-647152f94c5f - - - - -] The placement API endpoint not found. Placement is optional in Newton, but required in Ocata. Please enable the placement service before upgrading.

I even try endpoint like http://controller:8778/placement ,http://controller:8780/placement,http://controller:8780,but still get same issue. and tcpdump -i any portrange 8700-8799 show nothing.Is there any step for setup Ocata send Placement API request?

If you used the installation guide on docs.openstack.org, it seems to have gaps regarding cells and placement API.

followed openstack ocata installation on ubuntu from this link.I have multinode environment with 3 nodes.One controller node running network services too and two compute nodes

https://docs.openstack.org/ocata/install-guide-ubuntu/nova-controller-install.html (https://docs.openstack.org/ocata/inst...) (https://docs.openstack.org/ocata/inst...)

After following the instructions i could not get placement service up on controller node.I then had to follow https://review.openstack.org/#/c/438328/15/doc/install-guide/source/nova-controller-install.rst (https://review.openstack.org/#/c/4383...) (https://review.openstack.org/#/c/4383...) specifically for configuration related to placement service and made some changes related to creation of placement endpoints.I had to use http://controller:8778 instead of http://controller/placement as documented in the instllation guide

After making changes the placement api status is success on controller node but compute nodes still give errors that placement-api is

Finally it worked for me following https://ask.openstack.org/en/question/105800/ocatathe-placement-api-endpoint-not-found-placement-is-optional-in-newton-but-required-in-ocata-please-enable-the-placement-service-before-upgrading/#.There (https://ask.openstack.org/en/question...) is a line in default nova.conf that needs to be commented out!

On my packstack-based installation, Placement runs as follows:

$ ps -ef|grep placement
nova      2424   625  0 03:21 ?        00:00:53 placement_wsgi  -DFOREGROUND

If it doesn't run on your controller, check the Nova log files for startup errors.

Bernd Bausch ( 2017-04-24 22:22:27 -0500 )edit

If it does run, and you see it listening on port 8778, run openstack catalog list to see the placement API endpoint. Try to find out why the compute nodes can't access that endpoint (e.g. on the compute nodes, get a token using placement authentication and use it to access the endpoint via curl).

Bernd Bausch ( 2017-04-24 22:25:12 -0500 )edit

Perhaps debug logging provides more info. Enable it if you haven't done it yet.

hey there it not so complicated just open these ports on controller(s) 5000,5672,8778 (tcp & udp)

REMEMBER in centos 7 you (can't do that from iptables!) use:

firewall-cmd --zone=public --add-port=5000/tcp --permanent firewall-cmd --reload

under the placement section, project_domain_name has to be 'default' or 'Default'. Or is the case immaterial?
