站长资讯网FastDFS是一个开源的轻量级分布式文件系统，由跟踪服务器（tracker server）、存储服务器（storage server）和客户端（client）三个部分组成，主要解决了海量数据存储问题，特别适合以中小文件（建议范围：4KB < file_size <500MB）为载体的在线服务。
（1）每次上传文件后都会返回一个地址，用户需要自己保存此地址。
（2）为了支持大容量，存储节点（服务器）采用了分卷（或分组）的组织方式。存储系统由一个或多个卷组成，卷与卷之间的文件是相互独立的，所有卷的文件容量累加就是整个存储系统中的文件容量。一个卷可以由一台或多台存储服务器组成，一个卷下的存储服务器中的文件都是相同的，卷中的多台存储服务器起到了冗余备份和负载均衡的作用。
配置环境：
CentOS 7.5 x 64
tracker server: 192.168.5.71（tracker暂时一台，后续再添加一台做nginx+keepalived高可用）
storage server: 192.168.5.72 192.168.5.73（group1）
storage server: 192.168.5.74 192.168.5.75（group2）
