在搭建Ubuntu上的OpenStack过程中遇到了多个挑战，包括Horizon访问错误500和504，Apache2配置问题，Nova管理和计算节点错误，以及Keystone、Placement和Neutron服务的故障。通过修改配置文件，如openstack-dashboard.conf和keystone.conf，重启服务，以及解决数据库和transport_url问题，逐步解决了这些问题。此外，针对Nova-compute的FileNotFoundError，调整了instances_path配置并重启服务。在遇到服务列表为空或升级检查失败时，删除并重建了cell，解决了内部服务器错误。最后，针对创建VM时的权限问题，检查并调整了Neutron的日志配置。

搭建文档参考官网教程：
https://docs.openstack.org/install-guide/

访问controller/horizon出错500：internal server error；访问controller/horizon出错504：internal server error gateway timeout

WSGIApplicationGroup %{GLOBAL}

把上面这行添加到/etc/apache2/conf-available/openstack-dashboard.conf

搭建apache2过程遇到35357没起来，更新/etc/apache2/sites-available/keystone.conf，添加35357配置部分

vim /etc/apache2/sites-available/keystone.conf

重启服务

service apache2 restart

跑过一遍su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose " nova，但是发现有错误配置需要重跑时报错

--transport-url not provided in the command line, using the value [DEFAULT]/transport_url from the configuration file

--database_connection not provided in the command line, using the value [database]/connection from the configuration file

方案1：带上对应更改的参数重跑

root@master01:/var/lib/glance/images# su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose --transport-url rabbit://openstack:casa@master01:5672/ --database_connection mysql+pymysql://nova:casa@master01/nova_api" nova

a4b73290-01bb-4c48-b39d-8fff66cf264e

方案2：删除错误的cells，重新添加

root@master01:/var/lib/glance/images# nova-manage cell_v2 list_cells
+-------+--------------------------------------+----------------------------------------+-----------------------------------------------+----------+
|  Name |                 UUID                 |             Transport URL              |              Database Connection              | Disabled |

计算节点nova-compute报错

ERROR nova.compute.manager [req-d31bb39b-74c5-4228-970e-b19625cfab85 - - - - -] Error updating resources for node node01.: FileNotFoundError: [Errno 2] No such file or directory: '/usr/lib/python3/dist-packages/instances'

添加参数 instances_path=/var/lib/nova/instances 到以下配置文件

root@node01:/etc/nova# vim /etc/nova/nova.conf
[DEFAULT]
transport_url = rabbit://openstack:casa@master01:5672/
my_ip = 172.0.16.19
use_neutron = True
firewall_driver = nova.virt.firewall.NoopFirewallDriver
instances_path=/var/lib/nova/instances

重启nova服务

service nova-api restart
service nova-consoleauth restart
service nova-scheduler restart
service nova-conductor restart
service nova-novncproxy restart

当配置完计算节点后，在控制节点执行openstack compute service list返回空

查看计算节点日志
