九、安装对象存储服务（swift），不使用控制節點數據庫服務，而於各存儲節點使用分布式SQLite數據庫。
9.1对象存储服务包括的组件
Proxy servers (swift-proxy-server)代理服務，接收API或HTTP請求，執行上傳文件、修改源數據、WEB瀏覽時列表文件和創建容器等操作。通常使用CACHE技術（memcache）提高性能
Account servers (swift-account-server)賬戶服務，管理對象存儲中的賬戶定義。
Container servers (swift-container-server)容器服務，在對象存儲中管理容器或文件夾映……
Object servers (swift-object-server)對象服務，在存儲節點管理實際的對象，比如文件。
Various periodic processes執行各種週期性任務，比如複製服務確保群集中數據一致性和可用性。其他包括審計、更新、以及資源回收等。
WSGI middleware處理認證，通常使用OPENSTACK Identity
swift client為用戶提供命令行接口使用REST API
swift-init初始化和構建RING文件腳本
swift-recon一個命令行工具，用於檢索群集的各種度量和測試信息。
swift-ring-builder存儲RING構建和再平衡工具
9.2控制节点安裝配置代理服務（proxy service），用於處理用戶、容器以及對象操作請求，可以部署多個節點提高性能和冗余。可以不基於OPENSTACK其他組件安裝，自身可提供認證機制。
9.2.1創建用戶以及API訪問點
