FastDFS：开源的高性能分布式文件系统；主要功能包括：文件存储，文件同步和文件访问，以及高容量和负载平衡
FastDFS：角色：跟踪服务器(Tracker Server)、存储服务器(Storage Server)和客户端(Client)
Tracker Server: 跟踪服务器，主要做调度工作，起到均衡的作用；负责管理所有的storage server和group，每个storage在启动后会连接 Tracker，告知自己所属 group 等信息，并保持周期性心跳。多个Tracker之间是对等关系，不存在单点故障
Storage Server: 存储服务器，主要提供容量和备份服务；以 group 为单位，每个 group 内可以有多台 storage server（高可用），组内的storage server上的数据互为备份
Client:客户端，上传下载数据的服务器
