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 [, e4 r; S0 \
iptables -I INPUT 1 -p tcp --dport 80 -j ACCEPT
$ ~/ t( \& w, z1 R
然后对iptables服务进行保存: 8 g& J$ k% G/ \& j+ P0 K
service iptables save " t$ [* `1 ]/ D$ S
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. # `# w" ?/ L3 o1 `7 q& m6 U0 u
解决方法:
1 }5 U' Z8 X$ U# H5 Z0 o b$ [systemctl stop firewalld 关闭防火墙
: b* J% P/ }6 x; V6 pyum install iptables-services 安装或更新服务
m- h$ C W: }1 ]' m
再使用systemctl enable iptables 启动iptables
" X! Q8 m+ Q; f, A+ L9 u最后 systemctl start iptables 打开iptables
6 J# K. t- T8 @. p/ H4 }' c
再执行service iptables save
0 J. g5 @2 n" b: H) K G" H: I
然后重启iptables服务: 5 j, ?: ]1 p) e
service iptables restart # m0 g5 N Z+ B( T
执行完毕之后/etc/syscofig/iptables文件就有了
