openstack octca 缺乏 placement Service 解決辦法

根據官方文檔安裝，當啓動nova-compute時會報錯

PlacementNotConfigured: This compute is not configured to talk to the placement service

緣由：官方文檔中遺漏了-nova-placement-api的安裝

我總結的安裝步驟

一、控制節點

yum install openstack-nova-placement-api

openstack service create --name placement --description "OpenStack Placement" placement

openstack endpoint create --region RegionOne placement public http://<ip>:8778

openstack endpoint create --region RegionOne placement admin http://<ip>:8778

openstack endpoint create --region RegionOne placement intenal http://<ip>:8778

systemctl restart httpd

二、計算節點

編輯 /etc/nova/nova.conf

增長

[placement]

auth_uri = http://controller:5000

auth_url = http://controller:35357

memcached_servers = controller:11211

auth_type = password

project_domain_name = default

user_domain_name = default

project_name = service

username = nova

password = ******

os_region_name = RegionOne

 重啓 systemctl restart openstack-nova-compute.service
