首先任意运行一条iptables防火墙规则配置命令如开通80端口: : b5 z, W; D& S6 [% @5 J7 U
iptables -I INPUT 1 -p tcp --dport 80 -j ACCEPT & z8 n/ T* W; f( y
然后对iptables服务进行保存:
' }3 s, O% t, z
service iptables save
% \7 j& P n; m5 W* b ?* l l
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.
+ x0 ^2 W% t( X) O: U
解决方法:
$ J( B/ ^1 m: G' Wsystemctl stop firewalld 关闭防火墙
$ m& M2 k6 m) R7 E% i: Lyum install iptables-services 安装或更新服务
; L" Q) p6 X3 C再使用systemctl enable iptables 启动iptables
" [- C/ f2 b5 A. p/ G最后 systemctl start iptables 打开iptables
2 n$ g! a, A4 S
再执行service iptables save
Q, L4 T4 b& [+ G0 B: H' r
然后重启iptables服务:
$ X) ?3 k2 m+ _3 V! j
service iptables restart " s: f& `& l9 O" o9 C
执行完毕之后/etc/syscofig/iptables文件就有了
