前言：
最近在研究云原生里面的OpenStack，因此，使用脚本打算搭建一套测试学习用的OpenStack平台，但OpenStack平台搭建完成后，发现了非常多的错误。感觉就是错误套错误，因此，记录一下错误发生的情况和如何解决错误，或许，会帮助到他人，毕竟，一个坑一个人跳就好了，不要都跳坑。
错误一：
ResourceProviderCreationFailed，此错误的详细日志记录如下：

2022-04-27 07:59:10.845 1274 ERROR nova.compute.manager那么，日志茫茫多，怎么排查呢？请注意开始的两段话：
Error updating resources for node controller.: ResourceProviderCreationFailed: Failed to create resource provider controller这里说的是更新控制节点的资源，无法创建资源以提供给控制端，直觉是placement api有问题，是不是placement用户的权限问题？
[root@controller ~]# openstack user list
+----------------------------------+-----------+
| ID | Name |
+----------------------------------+-----------+
| 1f9634bdf2ec47c68920201a2ee8174d | admin |
| 404e46ced80441e49b913e13003c83d2 | nova |

| b7fb795d186840e7b0645d6ccf784a07 | placement |
+----------------------------------+-----------+因此， 将该用户加入到admin组，执行命令：
openstack role add --project service --user placement admin但很可惜，这个命令报了第二个错：
[root@controller nova]# openstack role add --project service --user placement admin
You are not authorized to perform the requested action: identity:list_roles. (HTTP 403) (Request-ID: req-92f671b0-79a7-49c7-8ee5-bb4154946f4f)第二个错误解决后，查看日志可以看到错误消失了，正常的日志是这样的：
2022-**** *****5.454 1271 INFO nova.compute.manager [req-e2b80b65-d3d5-4651-9513-c57863b1e482 - - - - -] Updating bandwidth usage cache错误二：
openstack role add --project service --user placement admin 这个命令输出错误如下（正常情况下，此命令是没有任何输出的）：
You are not authorized to perform the requested action: identity:list_roles. (HTTP 403) (Request-ID: req-92f671b0-79a7-49c7-8ee5-bb4154946f4f)
这个错误是身份验证失败，其原因很多，但主要的常见的原因是token失效了，针对此问题，解决方法为重新生成token即可，因此，执行命令：
ADMIN_TOKEN=$(openssl rand -hex 10)
crudini --set /etc/keystone/keystone.conf DEFAULT admin_token $ADMIN_TOKEN
source admin-openrc.sh
再次执行openstack role add --project service --user placement admin 进行用户提权，成功，命令没有任何输出。
总结：
错误很多，也是互相有依赖的，OpenStack有非常多的错误是密码和权限相关的，因此，在搭建部署的时候要多注意哦。
