情况：媒体服务器上传小文件没问题，大一点的文件报这个错误。

原因：这是因为nginx限制了请求体大小

方案：需要在nginx的虚拟机配置文件中添加：

client_max_body_size 50m;

server{
    listen 80;
    server_name jesus.weyomusic.com;
    location / {
        proxy_set_header HOST $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_pass  http://ip:81;
    }
}
server{
    listen 80;
    server_name weyomusic.com www.weyomusic.com;
    location / {
        proxy_set_header HOST $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_pass http://ip:81;
        client_max_body_size 50M; 
    }
}
