首先任意运行一条iptables防火墙规则配置命令如开通80端口: - z5 U4 E) K4 a, Z) b
iptables -I INPUT 1 -p tcp --dport 80 -j ACCEPT . e' `1 q$ {# f& r& _/ m: J
然后对iptables服务进行保存:
6 ~1 T/ a" e! k& v0 a4 q
service iptables save 0 _; O7 o5 U, j( P ]
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.
* n& l. P& a1 K
解决方法:- P/ d5 A& |+ c# c
systemctl stop firewalld 关闭防火墙
- S( g, k. \, j8 Z+ dyum install iptables-services 安装或更新服务
% `' T0 ?+ b$ a再使用systemctl enable iptables 启动iptables
9 Y! n+ m; d% }9 A
最后 systemctl start iptables 打开iptables
( y0 e% F+ j; o
再执行service iptables save 3 k8 [. o9 E, ~0 n8 q
然后重启iptables服务: ' n) h/ ?% {! X! j( b% A5 I
service iptables restart s: Z3 H4 i6 b1 V. W/ L7 ~
执行完毕之后/etc/syscofig/iptables文件就有了 4 j& y( s/ Q" z1 x
