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—讓你在你的私有云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，爲Openstack雲平臺提供塊存儲服務，Cinder接口提供了一些標準功能，容許建立和附加塊設備到虛擬機，如「建立卷」，「刪除卷」和「附加捲」。還有更多高級的功能，支持擴展容量的能力，快照和建立虛擬機鏡像克隆，主要涉及到的組件以下：

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。它也能夠與這些進程經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。它也能夠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建立卷。其與「nova-scheduler「組件相似。

cinder-backup守護進程：「cinder-backup「服務提供任何種類備份捲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建立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

# mysql -ucinder -h192.168.10.100 -pcinder123
