nginx怎么反向代理到node？

Question

node的地址是127.0.0.1:2336
该怎么设置？

这是/etc/nginx/nginx.conf的内容，要加什么吗？

user              nginx;

worker_processes  1;

error_log  /var/log/nginx/error.log;

#error_log  /var/log/nginx/error.log  notice;

#error_log  /var/log/nginx/error.log  info;

pid        /var/run/nginx.pid;

events {

    worker_connections  1024;

}

http {

    include       /etc/nginx/mime.types;

    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '

                      '$status $body_bytes_sent "$http_referer" '

                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;

    #tcp_nopush     on;

    #keepalive_timeout  0;

    keepalive_timeout  65;

    #gzip  on;

    # Load config files from the /etc/nginx/conf.d directory

    # The default server is in conf.d/default.conf

    include /etc/nginx/conf.d/*.conf;

}
