V 11 FastDFS

一、概念：

<a href="https://github.com/happyfish100/fastdfs" target="_blank">https://github.com/happyfish100/fastdfs</a>

FastDFS is an open source high performance distributed file system (DFS). It's major functions include: file storing, file syncing and file accessing, and design for high capacity and load balance.

FastDFS（fast distribution filesystem）是一款開源的輕量級分布式FS，純C實作，支援linux、freeBSD等類unix系統，類似googleFS，不是通用的FS，隻能通過專有API通路，目前提供了C、java、php、.NET的API，為網際網路應用量身定做，追求高性能和高擴充性，可看作是基于檔案的key-valu pair存儲系統，稱作分布式檔案存儲服務更為合适，更适合存儲中小檔案，如4KB-500MB；最早在ali，是易道用車架構師餘慶寫的，現應用在jd、taobao、58、uc、51cto；

分布式FS（支援FUSE；不支援FUSE）；

分布式FS（把檔案分片存放；按原本檔案存放）；

注：

fuse，FS in userspace，使用者空間檔案系統，是Linux中用于挂載某些網絡空間，如SSH，到本地檔案系統的子產品，在SourceForge上可以找到相關内容；三種模式：核心模式、使用者空間模式、mount工具；

fastdfs兩種角色（tracker、storage）：

tracker server（追蹤伺服器，主要做排程工作，在通路中起LB作用，在記憶體中記錄叢集中group和storage server的狀态資訊，是連接配接client和storage server的樞紐，因為相關資訊全部在記憶體中，tracker server的性能非常高（它本身所需負載很小），一個較大的叢集中（如上百個group）有3台就足夠）；

storage server（存儲伺服器，檔案和檔案屬性（如metadata）都儲存在該server上）；

storage裡同組内的兩個server裡存儲的内容完全相同（相當于raid1）；

storage叢集中，組（或叫卷）群組之間不通信是互相獨立的，storage主動向tracker彙報狀态，所有組的容量累加就是整個存儲系統中的檔案容量，一個組可由一台或多台storage server組成，一個組内的所有單個存儲伺服器中的檔案都是相同的，一組中的多台存儲伺服器起到了備援備份和負載均衡的作用，在組中增加伺服器時，同步已有的檔案由系統自動完成，同步完成後，系統自動将新增伺服器切換到線上提供服務，當存儲空間不足或即将耗盡時，可動态添加組，隻需要增加一台或多台伺服器，并将它們配置為一個新的組，這樣就擴大了存儲系統的容量；

client與tracker聯系，由tracker配置設定storage給client（類似http的301跳轉）；

擴充整個fastdfs叢集容量，在storage裡加group即可；

fastdfs上傳機制：

上傳檔案時，file_id由storage server生成并傳回給client，file_id包含了組名、磁盤、目錄、檔案名，storage server可直接根據file_id定位到檔案；

fastdfs存儲檔案位置file_id：

file_id包含了組名、磁盤、目錄、檔案名，storageserver可直接根據file_id定位到檔案；

fastdfs下載下傳機制：

fastdfs同步機制：

fastdfs查找檔案：

二、操作：

node1（test5；192.168.23.133）；

node2（test6；192.168.23.134）；

node{1,2}既作為tracker server也作為storageserver；

1、php_client：

配置LNMP環境；

[root@test5 ~]# cd fastdfs-5.08/php_client/

[root@test5 php_client]# /usr/local/php/bin/phpize

3、fastdfs-nginx-module：

注：生産中每個storage server上都要裝fastdfs-nginx-module；

[root@test5 ~]# git clone https://github.com/happyfish100/fastdfs-nginx-module

在LNMP環境上操作：

FastDFS is an open source high performancedistributed file system. It's major functions include: file storing, filesyncing and file accessing (file uploading and file downloading), and it canresolve the high capacity and load balancing problem. FastDFS should meet therequirement of the website whose service based on files such as photo sharingsite and video sharing site.

FastDFS has two roles: tracker and storage.The tracker takes charge of scheduling and load balancing for file access. Thestorage store files and it's function is file management including: filestoring, file syncing, providing file access interface. It also manage the metadata which are attributes representing as key value pair of the file. Forexample: width=1024, the key is "width" and the value is"1024".

The tracker and storage contain one or moreservers. The servers in the tracker or storage cluster can be added to orremoved from the cluster by any time without affecting the online services. Theservers in the tracker cluster are peer to peer.

The storarge servers organizing by the filevolume/group to obtain high capacity. The storage system contains one or morevolumes whose files are independent among these volumes. The capacity of thewhole storage system equals to the sum of all volumes' capacity. A file volumecontains one or more storage servers whose files are same among these servers.The servers in a file volume backup each other, and all these servers are loadbalancing. When adding a storage server to a volume, files already existing inthis volume are replicated to this new server automatically, and when thisreplication done, system will switch this server online to providing storageservices.

When the whole storage capacity isinsufficiency, you can add one or more volumes to expand the storage capacity.To do this, you need to add one or more storage servers.

The identification of a file is composed oftwo parts: the volume name and the file name.

Client test code use client library pleaserefer to the directory: client/test.
