首先任意运行一条iptables防火墙规则配置命令如开通80端口:
5 e1 V2 o* L7 G3 U8 ~' Q: H: ]7 s
iptables -I INPUT 1 -p tcp --dport 80 -j ACCEPT 9 T' l7 x8 ?, v" B' P9 A5 P
然后对iptables服务进行保存:
3 k7 T5 d/ L6 D! X7 |2 l
service iptables save
# s6 L9 ~4 M, x5 k+ ^9 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.
. t+ q# y$ t" a# l
解决方法:% J* F; V' z2 g) S
systemctl stop firewalld 关闭防火墙 R* D) ]- _: S. O7 ~ f
yum install iptables-services 安装或更新服务
6 b! I, L) k, Q6 K再使用systemctl enable iptables 启动iptables
: E9 @. l% V2 s" R3 H
最后 systemctl start iptables 打开iptables + A2 j, K: H/ ^0 }: j
再执行service iptables save
, `% s; L q$ a4 m( a7 H
然后重启iptables服务: 1 ]0 _- _# M0 P. R' F& J9 r! F! A
service iptables restart
" I# h% c3 P9 {# i
执行完毕之后/etc/syscofig/iptables文件就有了 ' s+ z5 |2 c3 f
