413 Request Entity Too Large nginx

用Nginx-proxy 的网站，上传文件时碰到413错误的解决方法
只是要加一个任意名字的conf 文件到 /etc/nginx/conf.d/ 里面。 注意扩展名一定要是 .conf
加一行client_max_body_size 100m; 在这个文件里面就可以了
然后重启nginx proxy
以下是我在ubuntu 服务器中的操作命令

#I have the nginx-proxy docker container named as nginx-proxy as well, modify to your own name 
sudo docker exec -it nginx-proxy bash 
# 100m is a big size, you may want to reduce it 
echo 'client_max_body_size 100m;' > /etc/nginx/conf.d/my_proxy.conf 
exit 
sudo docker stop nginx-proxy 
sudo docker start nginx-proxy
