ERROR oslo_service.service PlacementNotConfigured 解决办法

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

原因：官方文档中遗漏了-nova-placement-api的安装

安装步骤

1、先安装openstack octca版本的yum源

yum install https://rdoproject.org/repos/rdo-release.rpm

2、控制节点

yum install openstack-nova-placement-api

firewall-cmd --zone=public --add-port=8778/tcp --permanent

firewall-cmd --reload

systemctl restart httpd

3、计算节点

编辑 /etc/nova/nova.conf

增加

[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

重启 systemctl restart openstack-nova-compute.service
