能不能出一个自动配置nodejs的？

通过nginx分发到nodejs的端口。
 
[root@iZ94mgg0rkrZ oneinstack]# more /usr/local/nginx/conf/vhost/nodedemo.sitename.conf
server {
listen 80;
server_name nodedemo.happyfit.studio;
access_log /data/wwwlogs/javademo.sitename.com_nginx.log combined;
index index.html index.htm;
root /data/wwwroot/javademo.sitename.com;

location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|flv|ico)$ {
    root /public/;
    expires 30d;
    access_log off;
    }
location ~ .*\.(js|css)?$ {
    root /public/
    expires 7d;
    access_log off;
    }
location ~ {
    proxy_pass http://127.0.0.1:3102;
    include proxy.conf;
    }
}
