python - flask-gunicorn-supervisor-nginx 配置无法启动nginx 8000端口

1. 使用flask-gunicorn-supervisor-nginx搭建web站.外网ip:8000无法访问.启动gunicorn+supervisor.服务器本地curl IP:8000端口返回主页数据.外网IP:8000无法返回数据.报错:port 8000: Connection refused

2. nginx配置如下:

nginx配置路径:/etc/nginx/sites-available/default

配置如下:

 server {
  1     listen 127.0.0.1;
  2     server_name localhost;
  3     root /home/nemo/openvideo/;
  4     access_log /home/nemo/openvideo/logs/access.log;
  5     error_log /home/nemo/openvideo/logs/access.log;
  6     location / {
  7         proxy_pass http://127.0.0.1:8000;
  8         proxy_set_header Host $host;
  9         proxy_set_header X-Real-IP $remote_addr;
 10     }
 11     location /static {
 12         alias  /home/nemo/openvideo/app/static/;
 13     }
 14 }

请帮忙看看配置是否有问题.或者其他方面的问题.谢谢!
