创建openstack镜像的时候报错。HTTP 500 Internal Server Error: The server has either erred or is incapable of performing the requested operation
查看 cat /var/log/glance/api.log日志显示如下。

尝试过
(1)重新配置glance-api.conf 和glance-registry.conf文件，
(2)同步数据库 su -s /bin/sh -c "glance-manage db_sync" glance
(3)用root用户更新权限，flush priviledegs
(4)配置cat /etc/httpd/conf.d/wsgi-keystone.conf文件，监听35357和5000端口
(5)重启环境变量admin.sh admin-openrc等
还有其他一些尝试，都不行。
最后我在错误日志里看到主机名和ip，我想会不会是因为公私网的ip顺序不对。

我打开/etc/hosts文件
是这样的
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
10.10.10.10 controller
10.10.10.12 compute
192.168.100.101 controller
192.168.100.102 compute
我把顺序调整一下之后。
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.100.101 controller
192.168.100.102 compute
10.10.10.10 controller
10.10.10.12 compute运行
成功
