glance对接cinder后端存储
案例准备
1.规划节点
| IP | 主机名 | 节点 |
|---|---|---|
| 192.168.100.10 | controller | Openstack Controller节点 |
2.基础准备
使用自行搭建的Openstack平台中修改相关参数，使glance可以使用cinder作为后端存储，将镜像存储于cinder卷中.
案例实施
(1)修改文件
修改glance配置文件
[root@controller ~]# vi /etc/glance/glance-api.conf
#show_multiple_locations = false
改为
show_multiple_locations = true
stores = file,http,
改为
stores = file,http,cinder
# 重启服务
[root@controller ~]# systemctl restart openstack-glance-*
修改cinder配置文件
[root@controller ~]# vi /etc/cinder/cinder.conf
# 使用cinder服务通过克隆创建镜像的新卷的配置是cinder
#allowed_direct_url_schemes =
改为
allowed_direct_url_schemes = cinder
#image_upload_use_internal_tenant = false
改为
image_upload_use_internal_tenant = True
# 重启服务
[root@controller ~]# systemctl restart openstack-cinder*
(2)创建镜像和卷
[root@controller ~]# openstack image create --disk-format qcow2 --container-format bare --file cirros-0.3.4-x86_64-disk.img cirros-image
