centos是不允许监听1024以上的端口，所以需要修改nginx端口成8080，然后使用防火墙转发到80端口到8080

1、 首先应该做的是/etc/sysctl.conf配置文件的 net.ipv4.ip_forward = 1 默认是0  这样允许iptalbes FORWARD。2、 service iptables stop  关闭防火墙3、 重新配置规则vi /etc/sysconfig/iptables在COMMIT之前添加：-A PREROUTING -p tcp --dport 80 -j REDIRECT --to-ports 8080-A OUTPUT -p tcp --dport 80 -j REDIRECT --to-ports 80805、 启动iptables 服务, service iptables restart
