一、Cinder块存储组件说明：
### --- Cinder块存储组件说明：
~~~ OpenStack块存储服务为云主机提供块存储设备。支持不同后端（针对于操作系统区分，可以是Windows，也可以是linux）
~~~ The Block Storage API和scheduler服务运行在controller节点（接口和调度服务）
~~~ The volume service运行在一个或多个存储节点；存储节点可以通过本地磁盘，SAN/NAS等后端设备为云主机提供卷存储。
~~~ cinder-api允许API请求，并路由他们到cinder-volume
~~~ cinder-volume直接与快存储服务交互，处理想cinder-scheduler这样的服务，通过消息队列相互通信，支持多种存储类型：iscsi协议执行的。
~~~ cinder-scheduler daemon选择最右的存储节点创建卷，类似于novascheduler
~~~ Messaging queue在块存储进程中传递信息。二、Cinder块存储代码构建
### --- Cinder块存储代码构建
~~~ OpenStack Block Storage(cinder)
~~~ 安装并配置controller节点
~~~ 配置先决条件
~~~ 安装并配置块存储控制组件
~~~ 完成安装一、配置先决条件
### --- 创建数据库，并完成下列步骤：
### --- 以数据库管理员root的身份连接数据库；
[root@controller ~]# mysql -uroot -p
Enter password:### --- 创建cinder数据库
MariaDB [(none)]> CREATE DATABASE cinder;
Query OK, 1 row affected (0.03 sec)### --- 创建数据库用户cinder，并授予cinder用户cinder数据库的完全控制权限：管理员权限，本地的权限
### --- 退出数据库连接
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'CINDER_DBPASS';
Query OK, 0 rows affected (0.06 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'CINDER_DBPASS';
Query OK, 0 rows affected (0.00 sec)### --- 执行admin环境变量脚本
[root@controller ~]# source admin-openrc.sh ### --- 在认证服务中心创建块存储服务认证信息，完成下列步骤：
### --- 创建cinder用户
[root@controller ~]# keystone user-create --name cinder --pass CINDER_PASS
