安装和配置服务
1. 建库建用户
mysql -u root -p CREATE DATABASE glance; GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY ''; GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY ''; 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token openstack 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
openstack service create --name glance --description "OpenStack Image" image +-------------+----------------------------------+
| Field | Value |
+-------------+----------------------------------+
| description | OpenStack Image |
| enabled | True |
| id | c1334a6d30644f399acb9a40f6d7dac5 |
| name | glance |
| type | image |
+-------------+----------------------------------+
建端点

| Field | Value |
+--------------+----------------------------------+
| enabled | True |

+--------------+----------------------------------+
3. 安装软件
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_namespaces connection = mysql+pymysql://glance:123456@controller01/glance [keystone_authtoken] auth_url = http://controller01:5000 memcached_servers = controller01:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = glance password = 123456 [paste_deploy] flavor = keystone [glance_store] stores = file,http default_store = file filesystem_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
su -s /bin/sh -c "glance-manage db_sync" glance
7. 启动服务
systemctl enable openstack-glance-api.service openstack-glance-registry.service
systemctl start openstack-glance-api.service openstack-glance-registry.service
验证操作
