安装和配置服务
1. 建库建用户
mysql -u root -pCREATE DATABASE glance;GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY '123456';GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY '123456';flush privileges;
2. keystone认证操作
上面提到过：所有后续项目的部署都统一放到一个租户service里，然后需要为每个项目建立用户，建管理员角色，建立关联
. admin-openrc # 修改环境变量获取tokenopenstack user create --domain default --password-prompt glance+---------------------+----------------------------------+| Field | Value |+---------------------+----------------------------------+| domain_id | 135e691ebbb74fefb5086970eac74706 || enabled | True || id | e8febba19a724bc7b27e5f485f43104b || name | glance || options | {} || password_expires_at | None |+---------------------+----------------------------------+openstack role add --project service --user glance admin 建立服务实体

建端点

3. 安装软件
1 yum install openstack-glance -y
4. 初始化存放镜像的存储设备
# 此处我们暂时用本地存储，但是无论哪种存储，都应该在glance启动前就已经有了，否则glance启动时通过驱动程序检索不到存储设备，# 即在glance启动后 新建的存储设备无法被glance识别到，需要重新启动glance才可以，因此我们将下面的步骤提到了最前面# 新建目录mkdir -p /var/lib/glance/images/chown glance. /var/lib/glance/images/
5. 修改配置
vim /etc/glance/glance-api.conf
[database]# 这里的数据库连接配置是用来初始化生成数据库表结构,不配置无法生成数据库表结构# glance-api不配置database对创建vm无影响，对使用metada有影响# 日志报错:ERROR glance.api.v2.metadef_namespacesconnection = mysql+pymysql://glance:123456@controller01/glance[keystone_authtoken]auth_url = http://controller01:5000memcached_servers = controller01:11211auth_type = passwordproject_domain_name = defaultuser_domain_name = defaultproject_name = serviceusername = glancepassword = 123456[paste_deploy]flavor = keystone[glance_store]stores = file,httpdefault_store = filefilesystem_store_datadir = /var/lib/glance/images/
vim /etc/glance/glance-registry.conf
[database]#这里的数据库配置是用来glance-registry检索镜像元数据connection = mysql+pymysql://glance:123456@controller01/glance
6. 同步数据库
此处会报一些关于future的问题，自行忽略
1 su -s /bin/sh -c "glance-manage db_sync" glance
7. 启动服务
1 systemctl enable openstack-glance-api.service openstack-glance-registry.service2 systemctl start openstack-glance-api.service openstack-glance-registry.service
