记录一次OpenStack-Train的创建实例错误。
问题描述
创建虚拟机实例的时候出现错误:
Unexpected API Error. Please report this at http://bugs.launchpad.net/nova/ and attach the Nova API log if possible. <class 'keystoneauth1.exceptions.http.Unauthorized'> (HTTP 500) (Request-ID: req-89a91418-1eff-497e-a3f6-e92d9a61cd9f)
问题分析
Nova-api日志
2021-08-07 18:51:10.263 20866 ERROR nova.network.neutronv2.api [req-7975a767-8612-4d8f-928f-fc56cdd079a4 8186828629f241ee98a33dd99edd1c2a 51054bfb82f24faa9e5f9647aa70821a - default default] The [neutron] section of your nova configuration file must be configured for authentication with the networking service endpoint. See the networking service install guide for details: https://docs.openstack.org/neutron/latest/install/
分析日志以后发现nova-api的错误而导致其他的网络服务器超时。
根据提示“The [neutron] section of your nova configuration file must be configured for authentication with the networking service endpoint.”大概意思是 必须将nova配置文件的[neutron]部分配置为与网络服务端点进行身份验证。
按照错误提示打开官方按照文档：
https://docs.openstack.org/neutron/latest/install/
解决方案
1、修改控制节点nova.conf文件，添加[neutron]相关配置
vim /etc/nova/nova.conf [neutron] # ... auth_url=http://controller:5000 auth_type=password project_domain_name=default user_domain_name=default region_name=RegionOne project_name=service username=neutron password=NEUTRON_PASS service_metadata_proxy=true metadata_proxy_shared_secret=METADATA_SECRET
2、在控制节点重启nova计算服务
systemctl restart openstack-nova-api.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service
再次重新创建虚拟机实例问题解决。
