Image Service 用于提供给用户用于快速启动虚拟机的镜像文件，这样的服务称为glance服务。
Glance服务数据库设定
在mysql中创建glance数据库:
root@JunoController:~# mysql -u root -p
Enter password:

创建Glance的user/role/tenant权限
用admin的权限，创建以下权限：
root@JunoController:~# source ~/openstack/admin-openrc.sh
创建glance用户:
root@JunoController:~# keystone user-create --name glance --pass engine
+----------+----------------------------------+
| Property | Value |
+----------+----------------------------------+
| email | |
| enabled | True |
| id | c706febbcc8843fb97383c9fdfba6214 |
| name | glance |
| username | glance |
+----------+----------------------------------+
用户glance属于admin角色，使用service tanant:
keystone user-role-add --user glance --tenant service --role admin
在keystone注册glance服务:
root@JunoController:~# keystone service-create --name glance --type image --description "OpenStack Image Service"
+-------------+----------------------------------+
| Property | Value |
+-------------+----------------------------------+
| description | OpenStack Image Service |
| enabled | True |
| id | 3d52d2992b9f423eb9868304e4405fab |
| name | glance |
| type | image |
+-------------+----------------------------------+
在keystone创建服务的end-point:
root@JunoController:~# keystone endpoint-create --service-id $(keystone service-list | awk '/ image / {print $2}') --publicurl http://10.17.17.211:9292 --internalurl http://10.17.17.211:9292 --adminurl http://10.17.17.211:9292 --region regionOne
+-------------+----------------------------------+
| Property | Value |
+-------------+----------------------------------+
| adminurl | http://10.17.17.211:9292 |
| id | f44400bebc07408d8e0f4e70a0d18475 |
| internalurl | http://10.17.17.211:9292 |
| publicurl | http://10.17.17.211:9292 |
| region | regionOne |
| service_id | 3d52d2992b9f423eb9868304e4405fab |

安装Glance服务
安装:
apt-get -y install glance python-glanceclient
配置:
# vim /etc/glance/glance-api.conf
[database]
# sqlite_db = /var/lib/glance/glance.sqlite
backend = sqlalchemy
connection = mysql://glance:engine@10.17.17.211/glance
[keystone_authtoken]
auth_uri = http://10.17.17.211:5000
auth_host = 10.17.17.211
auth_port = 35357
auth_protocol = http
admin_tenant_name = service
admin_user = glance
admin_password = engine
# vim /etc/glance/glance-registry.conf
[database]
# The file name to use with SQLite (string value)
#sqlite_db = /var/lib/glance/glance.sqlite
backend = sqlalchemy
connection = mysql://glance:engine@10.17.17.211/glance
[keystone_authtoken]
auth_uri = http://10.17.17.211:5000
auth_host = 10.17.17.211
auth_port = 35357
auth_protocol = http
admin_tenant_name = service
admin_user = glance
admin_password = engine
# rm -f /var/lib/glance/glance.sqlite
# su -s /bin/sh -c "glance-manage db_sync" glance
这里会碰到一个问题，解决方案如下:
root@JunoController:~# su -s /bin/sh -c "glance-manage db_sync" glance
2015-04-13 17:20:22.637 9455 CRITICAL glance [-] ValueError: Tables "migrate_version" have non utf8 collation, please make sure all tables are CHARSET=utf8

重启服务，
root@JunoController:~# service glance-registry restart
root@JunoController:~# service glance-api restart
验证Glance服务
首先下载镜像:
# wget http://cdn.download.cirros-cloud.net/0.3.3/cirros-0.3.3-x86_64-disk.img
创建Glance可见镜像:
# glance image-create --name "cirros-0.3.3-x86_64" --file cirros-0.3.3-x86_64-disk.img --disk-format qcow2 --container-format bare --is-public True --progress

好了，现在glance服务可以使用了，接下来将创建compute节点和网络节点。
