#### iptables开启警告 iptables: No config file. \[WARNING\]！ ####

*  **1、查看是/etc/sysconfig/iptables否存在**
    
        [root@iZ2ze3nze2sw4quaa8xor9Z sysconfig]# cd /etc/sysconfig/ && ls
        atd         clock      grub              iptables-config  modules     network-scripts  ntpdate        sandbox    sysstat                     udev
        auditd      console    i18n              irqbalance       netconsole  nginx            raid-check     saslauthd  sysstat.ioconf
        authconfig  crond      init              kernel           network     nginx-debug      readonly-root  selinux    system-config-firewall
        cbq         firstboot  ip6tables-config  keyboard         networking  ntpd             rsyslog        sshd       system-config-firewall.old
    
    > 出现上面错误，应该就是iptables不存在，如果不存在就生成iptables文件
 *  2、随便写一条iptables命令配置个防火墙规则，生成iptables文件  
    。如：iptables -P OUTPUT ACCEPT
    
        iptables -P OUTPUT ACCEPT
 *  **3、service iptables save保存**
    
        [root@iZ2ze3nze2sw4quaa8xor9Z sysconfig]# service iptables save
        iptables: Saving firewall rules to /etc/sysconfig/iptables:[  OK  ]
        
        [root@iZ2ze3nze2sw4quaa8xor9Z sysconfig]# ls
        atd         console    init              kernel      networking       ntpdate        saslauthd       system-config-firewall
        auditd      crond      ip6tables-config  keyboard    network-scripts  raid-check     selinux         system-config-firewall.old
        authconfig  firstboot  iptables          modules     nginx            readonly-root  sshd            udev
        cbq         grub       iptables-config   netconsole  nginx-debug      rsyslog        sysstat
        clock       i18n       irqbalance        network     ntpd             sandbox        sysstat.ioconf
 *  **4、启动防火墙**
    
        service iptables start //启动
        service iptables restart//重启
        service iptables stop //停止
        service iptables status //查看状态
