首先任意运行一条iptables防火墙规则配置命令如开通80端口:
! n' _* Y; V' [7 Y- i3 t
iptables -I INPUT 1 -p tcp --dport 80 -j ACCEPT o4 b6 ~4 k. k6 t% i
然后对iptables服务进行保存: D0 z8 A. l/ h: r# v' A
service iptables save
) R2 b8 `9 m9 |3 v% 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. 1 M# i' h# j0 B; P& F
解决方法:
* r3 _; j$ r# H( Zsystemctl stop firewalld 关闭防火墙
5 |5 C$ X9 V0 }yum install iptables-services 安装或更新服务
' ]- ?! @& L7 r. g1 W# U/ b% _; ^再使用systemctl enable iptables 启动iptables
2 v, `3 F+ A# Q8 N; H
最后 systemctl start iptables 打开iptables
. U Q! X0 Q$ Q% W6 M; g# K
再执行service iptables save & c$ e/ O2 h8 w. X, w- n4 ~
然后重启iptables服务: & m5 L( Q- s+ c" C6 W* F) T
service iptables restart
$ z8 c/ M5 @% B, R
执行完毕之后/etc/syscofig/iptables文件就有了
