Openstack(十七）部署快存儲cinder
官方部署文檔：https://docs.openstack.org/ocata/zh_CN/install-guide-rdo/cinder.html
OpenStack的存儲組件—Cinder和Swift—讓你在你的私有雲裏構建塊存儲和對象的存儲系統，Openstack從Folsom開始使用Cinder替換原來的Nova-Volume服務，為Openstack雲平臺提供塊存儲服務，Cinder接口提供了一些標準功能，允許創建和附加塊設備到虛擬機，如“創建卷”，“刪除卷”和“附加卷”。還有更多高級的功能，支持擴展容量的能力，快照和創建虛擬機鏡像克隆，主要涉及到的組件如下：
cinder-api：接受API請求，並將其路由到“cinder-volume“執行，即請求cinder要先請求此對外API。
cinder-volume：與塊存儲服務和例如“cinder-scheduler“的進程進行直接交互。它也可以與這些進程通過一個消息隊列進行交互。“cinder-volume“服務響應送到塊存儲服務的讀寫請求來維持狀態。它也可以和多種存儲提供者在驅動架構下進行交互。
cinder-scheduler守護進程：選擇最優存儲提供節點來創建卷。其與“nova-scheduler“組件類似。
cinder-backup守護進程：“cinder-backup“服務提供任何種類備份卷到一個備份存儲提供者。就像“cinder-volume“服務，它與多種存儲提供者在驅動架構下進行交互。
消息隊列：在塊存儲的進程之間路由信息。
17.1創建cinder數據庫
# mysql -uroot –p
> CREATE DATABASE cinder;
> GRANT ALL PRIVILEGES ON cinder.* TO ‘cinder‘@‘%‘ IDENTIFIED BY ‘cinde
r123‘;
> flush privileges;
17.2控制端數據訪問驗證
