同步数据库
su -s /bin/sh -c "glance-manage db_sync" glance
启动glance服务
systemctl enable openstack-glance-api.service && systemctl start openstack-glance-api.service
systemctl enable openstack-glance-registry.service && systemctl start openstack-glance-registry.service
Glance服务注册
想要让别的服务可以使用Glance，就需要在Keystone上完成服务的注册。注意需要先source一下admin的环境变量。
source admin-openstack.sh
openstack service create --name glance --description "OpenStack Image service" image
openstack endpoint create --region RegionOne image public http://192.168.56.11:9292
openstack endpoint create --region RegionOne image internal http://192.168.56.11:9292
openstack endpoint create --region RegionOne image admin http://192.168.56.11:9292
测试Glance状态
source admin-openstack.sh
openstack image list
Glance镜像
在刚开始实施OpenStack平台阶段，如果没有制作镜像。可以使用一个实验的镜像进行测试，这是一个小的Linux系统。
cd /usr/local/src && wget http://download.cirros-cloud.net/0.3.5/cirros-0.3.5-x86_64-disk.img
openstack image create "cirros" --disk-format qcow2 --container-format bare --file cirros-0.3.5-x86_64-disk.img --public
openstack image list
