首先说一下从零开始自己去搭一个fastdfs有多不顺，搭起来步骤繁琐,很麻烦，后来看到有人把做好的docker镜像传出来了，那搭建起来就很容易了
有服务器的可以自己在服务器上玩玩,没有的可以新建一个centos7.5虚拟机玩玩，遇到虚拟机不能上网和换阿里云的源的问题可以参考：
《解决centos7虚拟机不能上网并换成阿里云的源 》
在root权限下
yum install -y docker-io #安装docker
service docker star #启动docker
docker -v # 查看docker版本
docker pull qbanxiaoli/fastdfs
启动fastdfs
docker run -d --restart=always --privileged=true --net=host --name=fastdfs -e IP=192.168.127.131 -e WEB_PORT=80 -v ${HOME}/fastdfs:/var/local/fdfs qbanxiaoli/fastdfs
IP 后面是你的服务器公网ip或者虚拟机的IP，-e WEB_PORT=80 指定nginx端口
测试fastdfs是否搭建成功
docker exec -it fastdfs /bin/bash
echo "Hello FastDFS!">index.html
fdfs_test /etc/fdfs/client.conf upload index.html
图片能返回url就意见搭建成功
图片这样fastdfs就搭建好啦
加入依赖

在springboot启动类上加

运行测试类
图片返回的url就是能访问的地址
图片最后一张看效果
