配置Cento6.4 iptables防火墙。
1. 查看防火墙状态
# service iptables status或：
# /etc/init.d/iptables status
说明：下面也可以用此方法操作。
2.关闭 /开启/重启防火墙
# service iptables stop
# service iptables start
# service iptables restart
4.永久关闭防火墙
# chkconfig --level 35 iptables off
然后重启系统使其生效：
# shutdown -r now
5.设置开启80端口访问
>先查看防火墙状态：
[root@localhost nginx]# service iptables status
