FastDFS是一个开源的轻量级分布式文件系统，它对文件进行管理，功能包括：文件存储、文件同步、文件访问（文件上传、文件下载）等，解决了大容量存储和负载均衡的问题。特别适合以文件为载体的在线服务，如相册网站、视频网站等等。

FastDFS为互联网量身定制，充分考虑了冗余备份、负载均衡、线性扩容等机制，并注重高可用、高性能等指标，使用FastDFS很容易搭建一套高性能的文件服务器集群提供文件上传、下载等服务。

搭建环境

docker-compose.yml 文件编写

docker-compose.yml 
version: '2'
services:
  fastdfs-nginx:
    image: season/fastdfs:1.2
    hostname: fastdfs-nginx
    environment:
      TRACKER_SERVER: 10.42.113.136:22122
    volumes:
    - /root/rancher/develop/fastdfs/nginx.conf:/etc/nginx/conf/nginx.conf
    - /root/rancher/develop/fastdfs/store_path:/fastdfs/store_path
    command:
    - nginx
  fastdfs-tracker:
    image: season/fastdfs:1.2
    hostname: fastdfs-tracker
    volumes:
    - /root/rancher/develop/fastdfs/tracker_data:/fastdfs/tracker/data
    command:
    - tracker
  fastdfs-storage:
    image: season/fastdfs:1.2
    hostname: fastdfs-storage
    environment:
      TRACKER_SERVER: 10.42.113.136:22122
    volumes:
    - /root/rancher/develop/fastdfs/storage_data:/fastdfs/storage/data
    - /root/rancher/develop/fastdfs/store_path:/fastdfs/store_path
    command:

启动服务

验证

进入docker，查看tracker地址，如果错误，请修改主机中的 storage.conf后重启服务

上传成功，访问nginx
