openstack 的glance组件使用cinder作为后端存储？求配置案例

cinder和glance的角色一样，都是存储服务，前者focuse volume，后者focuse image。

但两者都不负责具体的数据存储。

glance / cinder 都支持多种后端存储方案，比如ceph。

所以，我理解你的问题应该是“求glance使用ceph等分布式存储方案作为后端存储的配置案例”。

/etc/glance/glance-api.conf配置案例如下，供参考：

[code class=\"lang-Command\" lang=\"Command\"][DEFAULT]

show_image_direct_url = True
image_cache_dir = /***/openstack/glance/image-cache
