nodejs和Nginx共用80端口，原理也是反向代理。这根nodejs和apache共存是一样的。

[root@hatch ~]# cd /etc/Nginx/conf.d/

[root@hatch conf.d]# cp virtual.conf nodejs.conf

[root@hatch conf.d]# cat nodejs.conf
#
# A virtual host using mix of IP-,name-,and port-based configuration
#

server {
    listen       80;
    server_name  nodejs.stagingserver.com.au;

    location / {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-Nginx-Proxy true;
        proxy_pass http://localhost:8000/;    //反向代理到nodejs占用的8000端口
        proxy_redirect off;
    }
}

[root@hatch conf.d]# /etc/init.d/Nginx reload
