openstack报错：

[root@controller ~]# openstack volume service list
The server is currently unavailable. Please try again at a later time.<br /><br />
The Keystone service is temporarily unavailable.(HTTP 503)

操作：做cinder
报错原因：未在控制节点中的/etc/cinder/cinder.conf中配置[keystone_authtoken]内容：

[keystone_authtoken]
www_authenticate_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_id = default
user_domain_id = default
project_name = service
username = cinder
password = 123456

初始化数据库：

[root@controller cinder]# su -s /bin/sh -c "cinder-manage db sync" cinder

重启服务：控制节点

# systemctl restart openstack-nova-api.service
# systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service
# systemctl restart openstack-cinder-api.service openstack-cinder-scheduler.service
