云计算之openstack-newton版搭建（四）
镜像服务镜像服务（glance）是用户能够发现，注册和检索虚拟机的镜像，它提供了一个REST API，使您能够查询虚拟机映像元数据并检索实际映像。可以将通过Image服务提供的虚拟机映像存储在各种位置，从简单文件系统到对象存储系统（如OpenStack对象存储）。镜像默认放在/var/lib/glance/images/。
下面说一下glance服务的安装及配置
1.创建数据库
# mysql -uroot -p123456
mysql> CREATE DATABASE glance;
mysql> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' \
IDENTIFIED BY 'GLANCE_DBPASS';
mysql> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' \
IDENTIFIED BY 'GLANCE_DBPASS';
2.获取admin权限
# . admin-openrc
3.创建glance用户
# openstack user create --domain default --password-prompt glance
User Password:123456
Repeat User Password:123456
+---------------------+----------------------------------+
| Field | Value |
+---------------------+----------------------------------+
| domain_id | default |
| enabled | True |
| id | 09d8b7bbfe9748ffadff25bffc1b46cd |
| name | glance |
| password_expires_at | None |
+---------------------+----------------------------------+
将admin角色添加到glance用户和服务项目中
1
# openstack role add --project service --user glance admin
创建glance服务实例
# openstack service create --name glance \
--description "OpenStack Image" image
# openstack service create --name glance \
> --description "OpenStack Image" image
+-------------+----------------------------------+
| Field | Value |
+-------------+----------------------------------+
| description | OpenStack Image |
| enabled | True |
| id | d6319246d7e3486d86b54634f07c1cb8 |
| name | glance |
| type | image |
+-------------+----------------------------------+
4.创建image服务API端点
# openstack endpoint create --region RegionOne \
image public http://controller:9292
# openstack endpoint create --region RegionOne \
> image public http://controller:9292
+--------------+----------------------------------+
| Field | Value |
+--------------+----------------------------------+
| enabled | True |
| id | 621b1c8dabc9472591690d4dadbd4dff |
| interface | public |
| region | RegionOne |
| region_id | RegionOne |
| service_id | d6319246d7e3486d86b54634f07c1cb8 |
| service_name | glance |
| service_type | image |
| url | http://controller:9292 |
+--------------+----------------------------------+
# openstack endpoint create --region RegionOne \
image internal http://controller:9292
# openstack endpoint create --region RegionOne \
> image internal http://controller:9292
+--------------+----------------------------------+
| Field | Value |
+--------------+----------------------------------+
| enabled | True |
| id | f2d4366f844d415e9745c6d7d817d859 |
| interface | internal |
| region | RegionOne |
| region_id | RegionOne |
| service_id | d6319246d7e3486d86b54634f07c1cb8 |
| service_name | glance |
| service_type | image |
| url | http://controller:9292 |
+--------------+----------------------------------+
# openstack endpoint create --region RegionOne \
image admin http://controller:9292
# openstack endpoint create --region RegionOne \
> image admin http://controller:9292
+--------------+----------------------------------+
| Field | Value |
+--------------+----------------------------------+
| enabled | True |
| id | 48114b387628482f9ae11d0cdb29dce2 |
| interface | admin |
| region | RegionOne |
| region_id | RegionOne |
| service_id | d6319246d7e3486d86b54634f07c1cb8 |

+--------------+----------------------------------+
5.安装服务
# yum install openstack-glance -y
6.配置服务
修改/etc/glance/glance-api.conf
# cd /etc/glance/
# cp glance-api.conf glance-api.conf.bak
# egrep -v "^#|^$" glance-api.conf.bak > glance-api.conf
# vim glance-api.conf
...
connection = mysql+pymysql://glance:GLANCE_DBPASS@controller/glance
...
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = glance
password = 123456
...
flavor = keystone
...
stores = file,http
default_store = file
filesystem_store_datadir = /var/lib/glance/images/
修改/etc/glance/glance-registry.conf
# cd /etc/glance/
# cp glance-registry.conf glance-registry.conf.bak
# egrep -v "^#|^$" glance-registry.conf.bak glance-registry.conf
...
connection = mysql+pymysql://glance:GLANCE_DBPASS@controller/glance
...
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = glance
password = 123456
...
flavor = keystone
7.填充数据库
# su -s /bin/sh -c "glance-manage db_sync" glance
8.启动服务
# systemctl enable openstack-glance-api.service openstack-glance-registry.service
#systemctl start openstack-glance-api.service openstack-glance-registry.service
9.验证
下载镜像
# wget http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img
导入镜像
# openstack image create "cirros" \
--file cirros-0.3.4-x86_64-disk.img \
--disk-format qcow2 --container-format bare \
--public
# openstack image create "cirros" \
> --file cirros-0.3.4-x86_64-disk.img \
> --disk-format qcow2 --container-format bare \
> --public
