FastDFS是一個開源的輕量級分散式檔案系統,它對檔案進行管理,功能包括:檔案儲存、檔案同步、檔案訪問(檔案上傳、檔案下載)等,解決了大容量儲存和負載均衡的問題,同時也能做到在叢集環境下一臺機子上傳檔案,同時該組下的其他節點下也備份了上傳的檔案。做分散式系統開發時,其中要解決的一個問題就是圖片、音視訊、檔案共享的問題和資料備份,分散式檔案系統正好可以解決這個需求。FastDFS的服務主要有兩個角色Tracker和Storage,Tracker服務用於負責排程storage節點與client通訊,在訪問上起負載均衡的作用,和記錄storage節點的執行狀態,是連線client和storage節點的樞紐,Storage用於儲存檔案

到此,FastDFS伺服器叢集部署和整合客戶端到SpringBoot中已經完成,以後我們就可以愉快的使用FastDFS服務儲存我們的圖片等並備份。如果文章中有寫得不對的地方,請給我留言指出,大家一起學習進步。如果覺得我的文章給予你幫助,也請給我一個喜歡和關注。
