Controller节点：
1、创建glance数据库，授予权限：

$ mysql -u root -p
MariaDB [(none)]> CREATE DATABASE glance;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY '123456';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY '123456';
MariaDB [(none)]> exit;

2、创建glance用户：

$ . admin-openrc

$ openstack user create --domain default --password-prompt glance
User Password: 123456
Repeat User Password: 123456
+---------------------+----------------------------------+
| Field               | Value                            |
+---------------------+----------------------------------+
| domain_id           | default                          |
| enabled             | True                             |
| id                  | 5b7e76213b4b4945b7c702be5b595c0e |
| name                | glance                           |
| options             | {}                               |
| password_expires_at | None                             |
+---------------------+----------------------------------+

$ openstack role add --project service --user glance admin

3、创建glance服务实体：

$ openstack service create --name glance --description "OpenStack Image" image
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | OpenStack Image                  |
| enabled     | True                             |
| id          | b9cfd97d134e4ec2bf19d78306e85a5a |
| name        | glance                           |
| type        | image                            |
+-------------+----------------------------------+

4、创建API端点：

$ openstack endpoint create --region RegionOne image public http://controller:9292
+--------------+----------------------------------+
| Field        | Value                            |
+--------------+----------------------------------+
| enabled      | True                             |
| id           | b9c90172de704ea4a867190ba44fc931 |
| interface    | public                           |
| region       | RegionOne                        |
| region_id    | RegionOne                        |
| service_id   | b9cfd97d134e4ec2bf19d78306e85a5a |
| service_name | glance                           |
| service_type | image                            |
| url          | http://controller:9292           |
+--------------+----------------------------------+

$ openstack endpoint create --region RegionOne image internal http://controller:9292
+--------------+----------------------------------+
| Field        | Value                            |
+--------------+----------------------------------+
| enabled      | True                             |
| id           | 074bde7662044e93830f4eca15d9c887 |
| interface    | internal                         |
| region       | RegionOne                        |
| region_id    | RegionOne                        |
| service_id   | b9cfd97d134e4ec2bf19d78306e85a5a |
| service_name | glance                           |
| service_type | image                            |
| url          | http://controller:9292           |
+--------------+----------------------------------+

$ openstack endpoint create --region RegionOne image admin http://controller:9292
+--------------+----------------------------------+
| Field        | Value                            |
+--------------+----------------------------------+
| enabled      | True                             |
| id           | 17030061f9b84301ac515765706933b2 |
| interface    | admin                            |
| region       | RegionOne                        |
| region_id    | RegionOne                        |
| service_id   | b9cfd97d134e4ec2bf19d78306e85a5a |
| service_name | glance                           |
| service_type | image                            |
| url          | http://controller:9292           |
+--------------+----------------------------------+

5、安装和配置：

# yum install openstack-glance

# vi /etc/glance/glance-api.conf
[database]
connection = mysql+pymysql://glance:123456@controller/glance
[glance_store]
stores = file,http
default_store = file
filesystem_store_datadir = /var/lib/glance/images/
[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = glance
password = 123456
[paste_deploy]
flavor = keystone


# vi /etc/glance/glance-registry.conf
[database]
connection = mysql+pymysql://glance:123456@controller/glance
[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = glance
password = 123456
[paste_deploy]
flavor = keystone

# su -s /bin/sh -c "glance-manage db_sync" glance

6、完成安装

# systemctl enable openstack-glance-api.service openstack-glance-registry.service
# systemctl start openstack-glance-api.service openstack-glance-registry.service

7、验证操作

$ . admin-openrc

$ wget http://download.cirros-cloud.net/0.3.5/cirros-0.3.5-x86_64-disk.img

$ openstack image create "cirros" \
  --file cirros-0.3.5-x86_64-disk.img \
  --disk-format qcow2 --container-format bare \
  --public
