首先任意运行一条iptables防火墙规则配置命令如开通80端口:
. t1 f1 o( }5 g2 l" K- n% r2 I. Y
iptables -I INPUT 1 -p tcp --dport 80 -j ACCEPT
, [, ]' u" |: L' y' H2 S6 |9 X
然后对iptables服务进行保存: 3 e+ ^/ c' z- C& N/ p b* C1 d$ w- z
service iptables save
3 i/ X& Q. l( ^+ z& G5 X! T4 K
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. $ y* P) o$ u0 i; } H
解决方法:! t2 t9 ~9 O& d. ?- N' \; P3 n5 Q
systemctl stop firewalld 关闭防火墙
- x N( _/ U+ i1 iyum install iptables-services 安装或更新服务
2 |' [$ y! J/ f" e; Q" [再使用systemctl enable iptables 启动iptables
7 y5 N2 I8 ], L5 ` S! G最后 systemctl start iptables 打开iptables
+ T; k* ^- o- F9 G
再执行service iptables save
# l/ X# i( N$ _% e; U9 ~( r& C/ j
然后重启iptables服务:
; ]+ |) \ r1 X2 ?' m
service iptables restart - {$ [0 @3 B! D; l1 d
执行完毕之后/etc/syscofig/iptables文件就有了
