首先任意运行一条iptables防火墙规则配置命令如开通80端口: + w$ C( Q1 w7 V; k- H
iptables -I INPUT 1 -p tcp --dport 80 -j ACCEPT
- [8 \: |9 V0 m% ^7 Z+ Y
然后对iptables服务进行保存:
5 j6 N: }( U5 I7 f
service iptables save
1 ^. \0 ~+ W0 s6 d& 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. " G: x3 r! l9 Z; V. w- }0 F
解决方法:: ^% C5 V, x2 T/ D
systemctl stop firewalld 关闭防火墙 + [+ i3 o# r( q& N
yum install iptables-services 安装或更新服务
; L7 U7 |' j" k* N4 o5 y再使用systemctl enable iptables 启动iptables
4 G6 k; Z/ g* J! Y2 D! L; ]最后 systemctl start iptables 打开iptables
5 H( f8 x/ R1 g# H! s. W: e
再执行service iptables save
) \8 }1 [0 ?- O8 x7 v- ]
然后重启iptables服务:
( n; ^% {9 _! u! q
service iptables restart 2 G1 K3 |( n! N) w2 v U; z7 u
执行完毕之后/etc/syscofig/iptables文件就有了
/ Y: ^2 u) C0 L* p; D |
