b.配置镜像注册服务
# vim /etc/glance/glance-registry.conf [database]---配置数据库访问[用户名:密码@控制节点] connection = mysql+pymysql://glance:glance@192.168.30.145/glance [keystone_authtoken]---配置身份服务访问 auth_uri = http://192.168.30.145:5000 auth_url = http://192.168.30.145:35357 memcached_servers = 192.168.30.145:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = glance password = glance [paste_deploy] flavor = keystone # grep ^[a-z] /etc/glance/glance-registry.conf sqlite_db = /var/lib/glance/glance.sqlite backend = sqlalchemy connection = mysql+pymysql://glance:glance@192.168.30.145/glance auth_uri = http://192.168.30.145:5000 auth_url = http://192.168.30.145:35357 memcached_servers = 192.168.30.145:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = glance password = glance flavor = keystone
5.同步镜像服务数据库
# su -s /bin/sh -c "glance-manage db_sync" glance
6.重启服务
# service glance-registry restart # service glance-api restart # service glance-registry status # service glance-api status
7.验证操作
使用 CirrOS 对镜像服务进行验证
CirrOS是一个小型的Linux镜像，可以用来进行 OpenStack部署测试。
a.获取管理员权限
# . admin-openrc
b.下载源镜像
# wget http://download.cirros-cloud.net/0.3.5/cirros-0.3.5-x86_64-disk.img
c.使用 QCOW2 磁盘格式， bare 容器格式上传镜像到镜像服务并设置公共可见
# openstack p_w_picpath create "cirros"\ --file cirros-0.3.5-x86_64-disk.img \ --disk-format qcow2 --container-format bare \ --public +------------------+------------------------------------------------------+ | Field | Value | +------------------+------------------------------------------------------+ | checksum | f8ab98ff5e73ebab884d80c9dc9c7290 | | container_format | bare | | created_at | 2017-03-29T05:57:56Z | | disk_format | qcow2 | | file | /v2/p_w_picpaths/4b6ebd57-80ab-4b79-8ecc-53a026f3e898/file | | id | 4b6ebd57-80ab-4b79-8ecc-53a026f3e898 | | min_disk | 0 | | min_ram | 0 | | name | cirros | | owner | 2461396f6a344c21a2360a612d4f6abe | | protected | False | | schema | /v2/schemas/p_w_picpath | | size | 13267968 | | status | active | | tags | | | updated_at | 2017-03-29T05:57:56Z | | virtual_size | None | | visibility | public | +------------------+------------------------------------------------------+
d.确认镜像的上传并验证属性
# openstack p_w_picpath list +--------------------------------------+--------+--------+ | ID | Name | Status | +--------------------------------------+--------+--------+ | 4b6ebd57-80ab-4b79-8ecc-53a026f3e898 | cirros | active | +--------------------------------------+--------+--------+
