openstack学习（三）：glance配置以及使用

记录，方便查阅。

---

只需要在controller节点安装。

配置

建立数据库；

mysql -uroot -p123456 -e "create database glance;grant all privileges on glance.* to 'glance'@'192.168.23.11' identified by 'glance'; grant all privileges on glance.* to 'glance'@'%' identified by 'glance';"

创建keystone中的用户、服务等

source admin-openrc.sh 　　#导入管理员变量
keystone user-create --name glance --pass glance --email [email protected]

keystone user-role-add --user glance --tenant service --role admin
 
keystone service-create --name glance --type image --description "Openstack Image Service"

keystone endpoint-create \
--service-id $(keystone service-list | awk '/ image / {print $2}') \
--publicurl http://controller:9292 \
--internalurl http://controller:9292 \
--adminurl http://controller:9292 \
--region regionOne

安装配置

yum install openstack-glance python-glanceclient -y

编辑配置文件/etc/glance/glance-api.conf

[DEFAULT]
verbose=True
notification_driver = noop　　#配置为noop，禁用notification（通知）

[database]
connection=mysql://glance:glance@controller/glance

[keystone_authtoken]
auth_uri = http://controller:5000/v2.0
identity_uri = http://controller:35357
admin_tenant_name = service
admin_user = glance
admin_password = glance

[paste_deploy]
flavor=keystone

[glance_store]　　　　#镜像后端存储，使用本地文件系统
default_store = file
filesystem_store_datadir = /var/lib/glance/images/

 编辑配置文件registry.conf

[DEFAULT]
verbose=True

[database]
connection=mysql://glance:glance@controller/glance

[keystone_authtoken]
auth_uri=http://controller:5000/v2.0
identity_uri=http://controller:35357
admin_tenant_name=service
admin_user=glance
admin_password=glance

[paste_deploy]
flavor = keystone

同步数据表：

glance-manage db_sync

检验数据表：

  mysql -uglance -pglance -e 'use glance;show tables;'

+----------------------------------+

启动和自启动：

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

debug模式启动：

glance-api --config-file=/etc/glance/glance-api.conf
#出错，修改文件权限
chown glance:glance /var/log/glance/api.log
chown glance:glance /var/lib/glance/images/

使用

上传镜像并查看：

glance image-create --name cirros --is-public true --container-format bare --disk-format qcow2 < cirros-0.3.1-x86_64-disk.img

glance image-list

+--------------------------------------+---------+-------------+------------------+-----------+--------+
| ID | Name | Disk Format | Container Format | Size | Status |
+--------------------------------------+---------+-------------+------------------+-----------+--------+
| 34ffca7a-3182-4f37-a364-9f6e5ae0a5b2 | cirros | qcow2 | bare | 13147648 | active |
+--------------------------------------+---------+-------------+------------------+-----------+--------+

至此，glance安装完成，存储采用本地文件存储。

上传的镜像路径在/var/lib/glance/images/下：

[root@controller ~]# ll -h /var/lib/glance/images/
