存储的分类：
块存储：
硬盘
LVM
DAS(Direct Attach Storage)
是直接连接于主机服务器的一种存储方式，每一台主机服务器有独立的存储设备，每台主机服务器的存储设备无法互通。
通常用单一网络环境下且数据交换量不大，性能要求不高的环境下，可以说是一种应用较早的技术实现
SAN
1、FC-SAN
2、IP-SAN
分布式存储-Ceph
Ceph是开源实现的PB级别的分布式文件系统，其分布式对象存储机制为上层提供了文件接口、块存储接口和对象存储接口
DAS(Direct Attach Storage)
文件存储：
FS
对象存储：
SAN(storage Area Network)
NAS
Cinder组件：
chnder-api。接受API请求并将请求路由到cinder-volume来执行。
cinder-volume。相应请求，读取或写向块存储数据库为维护状态，通过信息队列机制与其他进程交互（如cinder-scheduler），或直接与上层块存储提供的硬件或软件进行交互。通过驱动结构，他可以与众多的存储提供者进行交互。
cinder-scheduler。守护进程。类型于nova-scheduler，为存储卷的实例选取最优的块存储供应节点。
没有Cinder时候虚拟机磁盘存放位置；
[[email protected] linux-node2 ~]# ls /var/lib/nova/instances/
_base compute_nodes e7585ece-c8e9-4ad8-8796-8a58bca459bf locks snapshots
[[email protected] linux-node2 ~]# ls /var/lib/nova/instances/e7585ece-c8e9-4ad8-8796-8a58bca459bf/
console.log disk disk.info libvirt.xml安装Cinder控制节点：[[email protected] ~]# yum -y install openstack-cinder python-cinderclient
查看是否已创建cinder数据库，我这里在keystone安装时候已经创建；
[[email protected] ~]# mysql -uroot -psmoke520

Bye配置Cinder：
[[email protected] ~]# vim /etc/cinder/cinder.conf
[database]
connection = mysql://cinder:[email protected]/cinder同步数据库：[[email protected] ~]# su -s /bin/sh -c "cinder-manage db sync" cinder
