准备

在安装和配置Image服务之前，必须创建数据库、服务凭据和API端点。
数据库：

mysql

MariaDB [(none)]> CREATE DATABASE glance;
Query OK, 1 row affected (0.000 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%'    IDENTIFIED BY 'admin1234';
Query OK, 0 rows affected (0.000 sec)

获取admin凭据以获得对admin-only CLI命令的访问权限:

root@controller:~# mv /etc/keystone/admin-openrc.sh  /root/
root@controller:~# ls
admin-openrc.sh  snap

root@controller:~# . admin-openrc.sh

要创建服务凭据，请完成以下步骤:
创建glance用户:

root@controller:~# openstack user create --domain default --password-prompt glance
User Password:
Repeat User Password:
+---------------------+----------------------------------+
| Field               | Value                            |
+---------------------+----------------------------------+
| domain_id           | default                          |
| enabled             | True                             |
| id                  | 210c20735e8b4e23b042b1531f8eea37 |
| name                | glance                           |
| options             | {}                               |
| password_expires_at | None                             |
+---------------------+----------------------------------+

在glance用户和业务群组中添加admin角色:

root@controller:~# openstack role add --project service --user glance admin
root@controller:~# 
root@controller:~#

创建glance服务实体:

root@controller:~# openstack service create --name glance \
>   --description "OpenStack Image" image
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | OpenStack Image                  |
| enabled     | True                             |
| id          | d1c2d187563b4229920e7b6baf702d01 |
| name        | glance                           |
| type        | image                            |
+-------------+----------------------------------+

创建服务API端点：

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

root@controller:~# openstack endpoint create --region RegionOne \
>   image public http://controller:9292
