Glance搭建

Glance搭建

1. 根据平台安装步骤安装至镜像服务，在控制节点使用提供的脚本 iaas-install-glance.sh 安装 glance 组件。使用镜像文件 CentOS_7.2_x86_64_XD.qcow2 创建 glance 镜像名为 CentOS7.2，格式为 qcow2， 将操作命令和执行结果提交到答题框。
   (glance help image-create)

[root@controller images]# glance image-create --name "CentOS7.2" --disk-format qcow2 --container-format bare --progress < /opt/iaas/images/CentOS_7.2_x86_64_XD.qcow2

2.使用 glance 相关命令查询 glance 镜像列表，并查询 CentOS7.2 镜像的详 细信息，将操作命令和返回结果提交到答题框。

[root@controller images]# glance image-list
+--------------------------------------+-----------+

+--------------------------------------+-----------+
| 6e1e8ce1-4776-4829-86c1-56f8cf5bffcc | CentOS7.2 |
+--------------------------------------+-----------+

[root@controller images]# glance image-show 6e1e8ce1-4776-4829-86c1-56f8cf5bffcc
+------------------+--------------------------------------+

| visibility       | private                              |
+------------------+--------------------------------------+

[root@controller images]#mysql –uroot –p000000
[root@controller images]#SHOW DATABASES;
[root@controller images]#USE glance
[root@controller images]#SHOW TABLES;
[root@controller images]#SELECT * FROM images;

3.使用 systemctl 相关命令，在一条命令中查询 glance 组件中所有服务的状 态信息，将操作命令和返回结果以文本形式提交到答题框.

[root@controller /]# systemctl status openstack-glance-registry.service openstack-glance-api.service
