拉取镜像并启动

docker run -d --restart=always --privileged=true --net=host --name=fastdfs -e IP=106.54.238.xxx -e WEB_PORT=8000 -v ${HOME}/fastdfs:/var/local/fdfs registry.cn-beijing.aliyuncs.com/tianzuo/fastdfs

 需要开放3个端口, fastdfs-tracker(22122)  fastdfs-storage(23000)  fastdfs-nginx(8000)

firewall-cmd --zone=public --add-port=8000/tcp --permanent

firewall-cmd --reload

$HOME是用户的主目录，登录后缺省进入的目录, cd ~进入

其中-v ${HOME}/fastdfs:/var/local/fdfs是指：将${HOME}/fastdfs这个目录挂载到容器里的/var/local/fdfs这个目录里。

所以上传的文件将被持久化到${HOME}/fastdfs/storage/data里，IP 后面是自己的服务器公网ip或者虚拟机ip，

-e WEB_PORT=8000 指定nginx端口

如果有问题可以看一下是否占用8000端口或是否开启22122 23000端口

• 引入依赖

  <dependency>
            <groupId>com.github.tobato</groupId>
            <artifactId>fastdfs-client</artifactId>
        </dependency>

•  配置

fdfs:
  so-timeout: 1501  #超时时间
  connect-timeout: 601  #连接超时时间
  thumb-image:  #上传原图和缩略图，可返回缩略图url给前端
    width: 60
    height: 60
  tracker-list:  #tracker地址
    - 106.54.238.xxx:22122   #多个 trackerServer中间以逗号分隔
