首先任意运行一条iptables防火墙规则配置命令如开通80端口: " \8 d" T+ J6 f
iptables -I INPUT 1 -p tcp --dport 80 -j ACCEPT % @8 B. `; F& h/ Y; K5 V
然后对iptables服务进行保存: 4 l+ _ [$ k$ q: N/ @4 r8 n
service iptables save
6 K" _+ n. J0 J5 x/ R
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. 3 ~# T) H5 y7 G
解决方法:, P( m5 M( \. g d1 M
systemctl stop firewalld 关闭防火墙 6 M/ i$ u$ C/ l3 b% ]
yum install iptables-services 安装或更新服务
% f! o, x5 |1 \6 {0 }) t9 `再使用systemctl enable iptables 启动iptables
8 _2 a) f! Y( e' n! p
最后 systemctl start iptables 打开iptables
u/ j5 U; T; A( T- f9 E1 n
再执行service iptables save
& Q7 J8 A' z2 O4 J8 T
然后重启iptables服务:
3 O% C. o+ l/ c( Z
service iptables restart 7 Z$ c4 F) E. p7 c5 D( i
执行完毕之后/etc/syscofig/iptables文件就有了
