来源：blog.csdn.net/qq_37759106/article/details/82981023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 yum install -y docker-io #安装dockerservice docker star #启动dockerdocker -v # 查看docker版本
docker pull qbanxiaoli/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docker exec -it fastdfs /bin/bashecho 'Hello FastDFS!'>index.htmlfdfs_test /etc/fdfs/client.conf upload index.html
