nginx二级域名配置到文件夹

user root;
worker_processes  ;

events {
    worker_connections  ;
}

http {
    include       mime.types;
    default_type  application/octet-stream;
sendfile        on;
    keepalive_timeout  ;
        upstream nifd.cn {
                server 127.0.0.1: weight=;
                #server 123.57.254.32: weight=;
        }
    server {
        listen       ;
        server_name  *.nifd.cn;
        if ( $host ~* (.*)\.(.*)\.(.*) )
        {
                set $domain $;
        }

        location / {
                proxy_pass http://nifd.cn/$domain/$request_uri;
                index index.html index.php;
        }

        error_page        /50x.html;
        location = /50x.html {
            root   html;
        }
   }
}
