python3搭建下载服务器很简单，在需要共享的目录键入
python -m http.server 8888
这样就搭建好了。在浏览器访问 ip:8888 即可访问
自带的服务器没有上传文件功能，今天要实现上传文件功能。

只需要在需要共享的目录键入去（后台运行）
nohup python /py/1.py > log.out 2>&1 &
其中 /py/1.py 是上面那段程序保存的文件
log.out是日志文件，后台进程输出，详情自己看我标的代码参考吧，懒得码了
使用
touch 1.py 可以在当前目录下创建一个名为 1.py 的文件
vim 1.py 可以编辑1.py(:wq是保存并退出，:wq!是强制保存退出，:q是退出，:q!是强制退出)
代码参考：https://blog.csdn.net/xiaojin21cen/article/details/88991768#4_nohup____79
即可后台运行
