首先任意运行一条iptables防火墙规则配置命令如开通80端口: & `* v }8 y+ i l
iptables -I INPUT 1 -p tcp --dport 80 -j ACCEPT
' J3 P4 c- T: q) `6 c
然后对iptables服务进行保存: : M, b2 x) [4 u3 u+ }" j: q. ~, @
service iptables save
3 d& Y6 u. \: d" E
如果失败报出:The service command supports only basic LSB actions (start, stop, restart, try-restart, reload, force-reload, status). For other actions, please try to use systemctl. 4 d, A5 {& a0 o
解决方法:
7 |$ a' }" j7 a/ ysystemctl stop firewalld 关闭防火墙
$ N7 c2 U/ _9 A0 ?& w1 e0 Wyum install iptables-services 安装或更新服务
, ?' g8 P$ h0 m, t2 b再使用systemctl enable iptables 启动iptables
& g2 p A! o$ x$ G' n0 }" \7 K1 Q
最后 systemctl start iptables 打开iptables
+ @0 }$ `/ X9 L3 L6 ^7 R
再执行service iptables save 1 v% d% o. T0 ~
然后重启iptables服务:
& t; b" u: {1 t. J
service iptables restart 1 a) l: d( Y @2 m6 E& ~/ {' ?
执行完毕之后/etc/syscofig/iptables文件就有了 & q* @, [1 E+ \% p+ }
