V 11 FastDFS
一、概念：
https://github.com/happyfish100/fastdfs
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.
https://github.com/happyfish100/fastdfs-client-java
https://github.com/happyfish100/fastdfs-nginx-module
FastDFS（fast distribution filesystem）是一款开源的轻量级分布式FS，纯C实现，支持linux、freeBSD等类unix系统，类似googleFS，不是通用的FS，只能通过专有API访问，目前提供了C、java、php、.NET的API，为互联网应用量身定做，追求高性能和高扩展性，可看作是基于文件的key-valu pair存储系统，称作分布式文件存储服务更为合适，更适合存储中小文件，如4KB-500MB；最早在ali，是易道用车架构师余庆写的，现应用在jd、taobao、58、uc、51cto；
分布式FS（支持FUSE；不支持FUSE）；
分布式FS（把文件分片存放；按原本文件存放）；
注：
fuse，FS in userspace，用户空间文件系统，是Linux中用于挂载某些网络空间，如SSH，到本地文件系统的模块，在SourceForge上可以找到相关内容；三种模式：内核模式、用户空间模式、mount工具；
fastdfs两种角色（tracker、storage）：
tracker server（追踪服务器，主要做调度工作，在访问中起LB作用，在内存中记录集群中group和storage server的状态信息，是连接client和storage server的枢纽，因为相关信息全部在内存中，tracker server的性能非常高（它本身所需负载很小），一个较大的集群中（如上百个group）有3台就足够）；
storage server（存储服务器，文件和文件属性（如metadata）都保存在该server上）；
注：
storage里同组内的两个server里存储的内容完全相同（相当于raid1）；
storage集群中，组（或叫卷）和组之间不通信是相互独立的，storage主动向tracker汇报状态，所有组的容量累加就是整个存储系统中的文件容量，一个组可由一台或多台storage server组成，一个组内的所有单个存储服务器中的文件都是相同的，一组中的多台存储服务器起到了冗余备份和负载均衡的作用，在组中增加服务器时，同步已有的文件由系统自动完成，同步完成后，系统自动将新增服务器切换到线上提供服务，当存储空间不足或即将耗尽时，可动态添加组，只需要增加一台或多台服务器，并将它们配置为一个新的组，这样就扩大了存储系统的容量；
client与tracker联系，由tracker分配storage给client（类似http的301跳转）；
扩展整个fastdfs集群容量，在storage里加group即可；
fastdfs上传机制：
上传文件时，file_id由storage server生成并返回给client，file_id包含了组名、磁盘、目录、文件名，storage server可直接根据file_id定位到文件；
fastdfs存储文件位置file_id：
file_id包含了组名、磁盘、目录、文件名，storageserver可直接根据file_id定位到文件；
fastdfs下载机制：
fastdfs同步机制：
fastdfs查找文件：
二、操作：
node1（test5；192.168.23.133）；
node2（test6；192.168.23.134）；
node{1,2}既作为tracker server也作为storageserver；

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.
