三 验证

一 简单架构图示参考

二 部署glance

yum install memcached python-memcached

systemctl enable memcached.service

systemctl start memcached.service

step 1：glance关于数据库的操作

1. mysql -u root -p #登入数据库
2. CREATE DATABASE glance; #新建库keystone
3. GRANT ALL PRIVILEGES ON glance.* TO ‘glance’@’localhost’ \
4.   IDENTIFIED BY ‘123’; #新建本地访问glance库的账号
5. GRANT ALL PRIVILEGES ON glance.* TO ‘glance’@’%’ \
6.   IDENTIFIED BY ‘123’; #新建远程访问glance库的账号

复制代码
step 2：glance关于keystone的操作

1. soure admin-openrc #执行管理员脚本
2. #为glance的使用者创建用户
3. openstack user create –domain default –password-prompt glance
4. #对glance-service添加role角色,提示：用户glance只有在一个确定的项目service内才有角色的概念，单独的用户或者单独的项目都是无法绑定角色的。
5. openstack role add –project service –user glance admin
6. #创建glance服务的catalog：service+endpoint
7. openstack service create –name glance \
8. –description “OpenStack Image” image
9. openstack endpoint create –region RegionOne \
10. image public http://192.168.31.57:9292
11. openstack endpoint create –region RegionOne \
12. image internal http://192.168.31.57:9292
13. openstack endpoint create –region RegionOne \
14. image admin http://192.168.31.57:9292

复制代码
step 3：安装软件包

1. yum -y install openstack-glance

复制代码
step 4：配置/etc/glance/glance.conf

大前提：每一条配置都应该新增到文件中，一定不要打开注释在原有的基础上修改。

创建本地存储：

1.一定要在opesntack-glance-api.service服务启动之前部署好存储设备，因为该服务在启动时会加载存储驱动检索存储设备，如果事先不存在，就意味着该服务没有识别到任何可用的存储设备，即便是后来你又新增了存储，仍然是无效的，最终导致你上传镜像失败；

2.一定要赋予opesntack-glance-api.service服务对存储设备的可写权限。

1. mkdir -p /var/lib/glance/images
2. chown -R glance.glance /var/lib/glance/images

复制代码 配置/etc/glance/glance-api.conf

1. [database]
2. connection = mysql+pymysql://glance:123@192.168.31.57/glance
3. [keystone_authtoken]
4. auth_uri = http://192.168.31.57:5000
5. auth_url = http://192.168.31.57:35357
6. memcached_servers = 192.168.31.57:11211
7. auth_type = password
8. project_domain_name = Default
9. user_domain_name = Default
10. project_name = service
11. username = glance
12. password = 123
13. [paste_deploy]
14. flavor = keystone
15. [glance_store]
16. stores = file,http
17. default_store = file
18. filesystem_store_datadir = /var/lib/glance/images/

复制代码 配置/etc/glance/glance-registry.conf

1. [database]
2. connection = mysql+pymysql://glance:123@192.168.31.57/glance
3. [keystone_authtoken]
4. auth_uri = http://192.168.31.57:5000
5. auth_url = http://192.168.31.57:35357
6. memcached_servers = 192.168.31.57:11211
7. auth_type = password
8. project_domain_name = Default
9. user_domain_name = Default
10. project_name = service
11. username = glance
12. password = 123
13. [paste_deploy]
14. flavor = keystone

复制代码
step 5: 初始化数据库glance

1. su -s /bin/sh -c “glance-manage db_sync” glance
2. ”’
3. 忽略以下打印，此乃正常X：
4. Option “verbose” from group “DEFAULT” is deprecated for removal.  Its value may be silently ignored in the future.
5. /usr/lib/python2.7/site-packages/oslo_db/sqlalchemy/enginefacade.py:1171:…… oslo_db.sqlalchemy.enginefacade
6. …… a future release.”)
7.   result = self._query(query)
8. ”’

复制代码
step 6：启动glance且设置开机启动

1. systemctl enable openstack-glance-api.service \
2. openstack-glance-registry.service
3. systemctl start openstack-glance-api.service \
4. openstack-glance-registry.service

复制代码
三 验证

1. source admin-openrc
2. #如果没有wget则必须yum -y install wget
3. wget http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img
4. openstack image create “cirros” \
5.   –file cirros-0.3.4-x86_64-disk.img \
6.   –disk-format qcow2 –container-format bare \
7.   –public
8. openstack image list
