有人能帮我解决这个问题吗？

Answer 1

问题解决了。

根据日志，mod_wsgi中出现了错误。用于身份服务的Web服务网关接口(WSGI)中间件管道配置在keystone-paste.ini文件中，从而用openstack docs keystone-paste.ini文件验证了我的文件，从而改变了管道配置并解决了问题。

我编辑了/etc/keystone/keystone-paste.ini文件

1. 在pipeline:public_api下 管道=健康检查的cors，大小，http_proxy_to_wsgi，渗透剖面仪，url_normalize，request_id

将行上方更改为：

pipeline = healthcheck cors sizelimit http_proxy_to_wsgi osprofiler url_normalize request_id build_auth_context token_auth json_body ec2_extension public_service 

1. 相同方式编辑pipeline:admin_api 管道=健康检查的cors，大小，http_proxy_to_wsgi，渗透剖面仪，url_normalize，request_id

将管道改为：

pipeline = healthcheck cors sizelimit http_proxy_to_wsgi osprofiler url_normalize request_id build_auth_context token_auth json_body ec2_extension s3_extension admin_service 

1. 也在pipeline:api_v3中做了修改 管道=健康检查的cors，大小，http_proxy_to_wsgi，渗透剖面仪，url_normalize，request_id

将行上方更改为：

pipeline = healthcheck cors sizelimit http_proxy_to_wsgi osprofiler url_normalize request_id build_auth_context token_auth json_body ec2_extension_v3 s3_extension service_v3 

通过做以下改变，问题得到了解决。
