使用Nginx搭建文件服务器及实现文件服务的步骤

sudo apt-get update
sudo apt-get install nginx

sudo systemctl start nginx

sudo nano /etc/nginx/sites-available/myfileserver

server {
    listen 80;
    server_name test.com;
    location / {
           #指向文件存放的位置
           root /path/to/file;
           autoindex on;
           autoindex_exact_size off;
           charset utf-8;
    }
}
