Ubuntu搭建Openstack平台（kilo）(三.glance)

一.Glance环境
参考文档：http://www.aboutyun.com/thread-13080-1-1.html
http://docs.openstack.org/mitaka/install-guide-ubuntu/glance-install.html
1.创建glance的数据库并授权

• 创建

mysql -u root -p

CREATE DATABASE glance;

• 授权(自己设定密码，连接数据库时用，我的glance）

GRANT ALL PRIVILEGES ON glance.* TO ‘glance‘@‘localhost‘ IDENTIFIED BY ‘GLANCE_PASS‘;
GRANT ALL PRIVILEGES ON glance.* TO ‘glance‘@‘%‘ IDENTIFIED BY ‘GLANCE_PASS‘;

• 退出

exit

2.生效admin环境变量

source admin-openrc.sh

3.创建认证服务

• 创建glance用户

openstack user create --password-prompt glance
User Password:（我的设置glance)
Repeat User Password:
+-----------+----------------------------------+
| Field     | Value                            |
+-----------+----------------------------------+
| domain_id | e0353a670a9e496da891347c589539e9 |
| enabled   | True                             |
| id        | e38230eeff474607805b596c91fa15d9 |
| name      | glance                           |
+-----------+----------------------------------+

• 添加 admin 角色 到 glance 用户 和 service 租户(project)

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

• 创建glance的服务实例

openstack service create --name glance --description "OpenStack Image" image
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | OpenStack Image                  |
| enabled     | True                             |
| id          | 8c2c7f1b9b5049ea9e63757b5533e6d2 |
| name        | glance                           |
| type        | image                            |
+-------------+----------------------------------+

• 创建镜像服务的API endpoint

openstack endpoint create --publicurl http://controller:9292 --internalurl http://controller:9292 --adminurl http://controller:9292 --region RegionOne image
+--------------+----------------------------------+
| Field        | Value                            |
+--------------+----------------------------------+
| adminurl     | http://controller:9292           |
| id           | 340be3625e9b4239a6415d034e98aace |
| internalurl  | http://controller:9292           |
| publicurl    | http://controller:9292           |
| region_id    | RegionOne                        |
| service_id   | 8c2c7f1b9b5049ea9e63757b5533e6d2 |
| service_name | glance                           |
| service_type | image                            |
+--------------+----------------------------------+

二.安装Glance
1.安装

apt-get install glance python-glanceclient -y

2.修改配置

vim /etc/glance/glance-api.conf

[DEFAULT]
verbose = True
notification_driver = noop

[database]
connection = mysql://glance:GLANCE_DBPASS(glance数据库密码)@controller/glance

[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
project_name = service
username = glance
password = GLANCE_PASS（glance密码)

[paste_deploy]
flavor = keystone

[glance_store]
#配置本地文件系统存储和image文件路径
default_store = file
filesystem_store_datadir = /var/lib/glance/images/

保存退出。

vim /etc/glance/glance-registry.conf 

[DEFAULT]
verbose = True
notification_driver = noop

[database]
connection = mysql://glance:GLANCE_DBPASS(glance数据库密码)@controller/glance

[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
project_name = service
username = glance
password = GLANCE_PASS（glance密码)

[paste_deploy]
flavor = keystone

保存退出。

3.同步数据库（同步之后，可以看看数据库中是否存在表，有则成功，没有则表明可能sqlite数据库没删，删除后在同步rm -f /var/lib/glance/glance.sqlite）

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

4.重启glance服务

service glance-registry restart
service glance-api restart

三.Glance验证
1.在每一个客户端脚本,配置镜像服务客户端使用 API version 2.0

echo "export OS_IMAGE_API_VERSION=2" | tee -a admin-openrc.sh demo-openrc.sh

2.source admin环境变量

source admin-openrc.sh

3.创建一个临时目录，下载镜像

mkdir /tmp/images
wget -P /tmp/images http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img

4.上传镜像到glance，镜像使用qcow2 格式

glance image-create --name "cirros-0.3.4-x86_64" --file /tmp/
cirros-0.3.4-x86_64-disk.img --disk-format qcow2 --container-format bare --visibility public
progress

5.验证成功，并移除临时目录

glance image-list
+--------------------------------------+--------+
| ID                                   | Name   |
+--------------------------------------+--------+
| 38047887-61a7-41ea-9b49-27987d5e8bb9 | cirros |
+--------------------------------------+--------+

rm -r /tmp/images

注意：以前搭建的，可以运行，如果上面写的有一些问题，谢谢指出来。
