openstack glance組件上傳鏡像時報錯

[root@controller ~]# glance image-create --name "examimage" --disk-format "qcow2" --container-format bare --progress < /root/CentOS-68.qcow2

下面是執行上面命令所報錯：
You must provide a username via either --os-username or env[OS_USERNAME]
此時須要執行：source /etc/keystone/admin-openrc.sh

[root@controller ~]# glance image-create --name "examimage" --disk-format "qcow2" --container-format bare --progress < /root/CentOS-68.qcow2
public endpoint for image service not found

此時執行：openstack service create --name glance --description "OpenStack Image" image
openstack endpoint create --region RegionOne image public http://controller:9292
openstack endpoint create --region RegionOne image internal http://controller:9292
openstack endpoint create --region RegionOne image admin http://controller:9292
systemctl restart openstack-glance-api.service
