首先任意运行一条iptables防火墙规则配置命令如开通80端口: ! @7 b" j: @5 J* y% z
iptables -I INPUT 1 -p tcp --dport 80 -j ACCEPT + w# f( S J* ?' }/ B4 K& h$ s+ v
然后对iptables服务进行保存:
7 O& ~5 V# d- E$ L9 V
service iptables save 1 K3 |1 y5 ]* t" |
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 t7 H6 f' F" n# u6 k$ W
解决方法:& \$ K7 F5 B, h# F) m5 j; z
systemctl stop firewalld 关闭防火墙
; G/ @9 L' ]% I( Pyum install iptables-services 安装或更新服务
0 p1 B9 H1 \- L7 V1 E
再使用systemctl enable iptables 启动iptables ; c+ ]8 |0 ~7 W W1 q( G
最后 systemctl start iptables 打开iptables - w0 W8 {3 o: F+ ]- a5 Y
再执行service iptables save
( M% L$ X3 J2 ?6 ]( y# g s
然后重启iptables服务: 2 I6 U$ S I! z: x% E/ ?
service iptables restart l4 }# H2 ~, {. F. Z2 C7 |7 a
执行完毕之后/etc/syscofig/iptables文件就有了 : k6 c( w5 y& t. s( n3 S7 f
