首先任意运行一条iptables防火墙规则配置命令如开通80端口:
2 h/ b5 h9 b! g2 a! J# i
iptables -I INPUT 1 -p tcp --dport 80 -j ACCEPT
' N. _# }5 I% Y9 ~4 I) }
然后对iptables服务进行保存: 4 m" I) v2 y+ H R5 W' i: Z2 o
service iptables save
! e$ B/ Y/ k& z/ E1 F# M
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.
( k9 X" d+ ^/ M0 m2 h
解决方法:
2 D' E# [4 X! h' ?# [- G, a, psystemctl stop firewalld 关闭防火墙 ! [% X: G: V C
yum install iptables-services 安装或更新服务 6 U- ^/ L) @5 ~7 { \( C
再使用systemctl enable iptables 启动iptables
; M- ^ e% e) Z+ h+ V最后 systemctl start iptables 打开iptables
9 N" ~1 y+ J- _: F9 l! z0 B7 d* r
再执行service iptables save
9 }/ Z6 `6 _- I* c' k9 O
然后重启iptables服务: . k; V1 P. U5 N9 s; {& S1 M
service iptables restart 2 M3 L5 {5 W# |" V+ D: @
执行完毕之后/etc/syscofig/iptables文件就有了 ! \8 |; @" w% D: ^
