cinder 就是 云硬盘
配置cinder步骤
1 安装软件包，然后到keystone注册
创建必要的用户名 密码
服务
endpoint
2 设置配置文件
yum install openstack-cinder -y keystone user-create --name cinder --pass hequan keystone user-role-add --user cinder --role admin --tennat services keystone service-create --name cinder --type volume --description cinderxxx 例子 关于cul keystone service-list | d1271040fa9144318a836a0b476d1e66 | cinder | volume | Cinder Service | keystone endpoint-list | grep d1271040fa9144318a836a0b476d1e66 | 8e18c46fc51c4a6287ea740a37537a59 | RegionOne | http://115.29.107.17:8776/v1/%(tenant_id)s | http://115.29.107.17:8776/v1/%(tenant_id)s | http://115.29.107.17:8776/v1/%(tenant_id)s | d1271040fa9144318a836a0b476d1e66 | keystone endpoint-create --service-id d1271040fa9144318a836a0b476d1e66 --publicul 'http://115.29.107.17:8776/v1/%(tenant_id)s' --internalurl 'http://115.29.107.17:8776/v1/%(tenant_id)s' --adminurl 'http://115.29.107.17:8776/v1/%(tenant_id)s' [root@hequan ~(keystone_admin)]# cd /etc/cinder/ [root@hequan cinder(keystone_admin)]# ls api-paste.ini policy.json rootwrap.d cinder.conf rootwrap.conf volumes [root@hequan cinder(keystone_admin)]# cp cinder.conf cinder.conf.bak ##备份 [root@hequan ~(keystone_admin)]# cp /usr/share/cinder/cinder-dist.conf /etc/cinder/cinder.conf ##复制配置文件 [root@hequan cinder(keystone_admin)]# chown root.cinder cinder.conf ##记得修改权限 [root@hequan cinder(keystone_admin)]# openstack-db --init -service cinder --password hequan --rootpw 123456 ##创建数据库
