一、基本概念
1.1、概述：OpenStack块存储服务(cinder)为虚拟机添加持久的存储，块存储提供一个基础设施为了管理卷，以及和OpenStack计算服务交互，为实例提供卷。此服务也会激活管理卷的快照和卷类型的功能。
1.2、基本组件
cinder-api 接受API请求，并将其路由到``cinder-volume``执行。
cinder-volume：与块存储服务和例如``cinder-scheduler``的进程进行直接交互。它也可以与这些进程通过一个消息队列进行交互。``cinder-volume``服务响应送到块存储服务的读写请求来维持状态。它也可以和多种存储提供者在驱动架构下进行交互。
cinder-scheduler守护进程：选择最优存储提供节点来创建卷。其与``nova-scheduler``组件类似。
cinder-backup守护进程：cinder-backup服务提供任何种类备份卷到一个备份存储提供者。就像``cinder-volume``服务，它与多种存储提供者在驱动架构下进行交互。
二、控制节点安装服务
1、创库授权
mysql -u root -pADMIN_PASS CREATE DATABASE cinder; GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'ADMIN_PASS'; GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'ADMIN_PASS';
2、在keysonte上创建系统用户
openstack user create --domain default --password ADMIN_PASS cinder openstack role add --project service --user cinder admin
3、在keysonte上创建服务和注册api
openstack service create --name cinderv2 --description "OpenStack Block Storage" volumev2 创建cinderv2服务实体 创建块设备存储服务的 API 入口点 openstack endpoint create --region RegionOne volumev2 public http://controller:8776/v2/%(tenant_id)s openstack endpoint create --region RegionOne volumev2 internal http://controller:8776/v2/%(tenant_id)s openstack endpoint create --region RegionOne volumev2 admin http://controller:8776/v2/%(tenant_id)s openstack service create --name cinderv3 --description "OpenStack Block Storage" volumev3 openstack endpoint create --region RegionOne volumev3 public http://controller:8776/v2/%(tenant_id)s openstack endpoint create --region RegionOne volumev3 internal http://controller:8776/v2/%(tenant_id)s openstack endpoint create --region RegionOne volumev3 admin http://controller:8776/v2/%(tenant_id)s
4、安装服务
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo yum makecache yum install centos-release-openstack-queens.noarch -y yum install openstack-cinder -y

6、配置计算节点以使用块设备存储
[cinder]
os_region_name = RegionOne
7、同步数据库
su -s /bin/sh -c "cinder-manage db sync" cinder
8、重启服务
控制节点重启计算API 服务
systemctl restart openstack-nova-api.service
计算节点重启openstack-nova-compute服务
systemctl restart openstack-nova-compute.service
9、启动服务
systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service
systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service
10、验证服务，web页面会多出一个卷管理
cinder service-list
三、存储节点安装服务
