阿里云配置ngxin，为静态服务器

nginx.conf  配置

   当我请求 http://192.168.0.1/uploadPath/j001/a.jpg   

   实际上找的是 /usr/local/source/uploadPath/j001/a.jpg   

   还有一点就是 务必保证 /usr/local/source/uploadPath 有权限 

   如果不确定 就执行命令 chmod -R 777 /user

   因为每次需要创建新的文件夹 ，加上这句话可以赋予权限

  Runtime.getRuntime().exec("chmod -R 777 " + uploadPath);

   location /uploadPath/ {
            root /usr/local/source/;
            autoindex on;
        }

server {
        listen       80 default_server;
        listen       [::]:80 default_server;
        server_name  _;
        root         /usr/share/nginx/html;

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;


        location /uploadPath/ {
            root /usr/local/source/;
            autoindex on;
        }


        error_page 404 /404.html;
            location = /40x.html {
        }

        error_page 500 502 503 504 /50x.html;
            location = /50x.html {
        }
    }
