首先任意运行一条iptables防火墙规则配置命令如开通80端口:
" a% _) M/ f! M( `9 J
iptables -I INPUT 1 -p tcp --dport 80 -j ACCEPT
2 j0 I+ I7 |4 Z( q! N
然后对iptables服务进行保存:
. S+ ~3 }. | m% M
service iptables save
. r ~$ {. r) c# L5 N
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. 0 K+ P6 c4 }( p) M. z, K% O
解决方法:
) F5 ?, t1 c$ L7 R" Qsystemctl stop firewalld 关闭防火墙
# b8 b8 C2 F$ ?9 B2 \; nyum install iptables-services 安装或更新服务
! u3 h+ N0 n' u0 \+ _8 p; j再使用systemctl enable iptables 启动iptables
]# o/ q& O S1 G R1 s
最后 systemctl start iptables 打开iptables ! y7 y7 u' l$ T4 y/ O0 {& R
再执行service iptables save - O T2 S0 s/ U8 m- z
然后重启iptables服务:
, a: ]' G5 l" A Y2 W/ Y
service iptables restart
/ V5 F S) l" ^
执行完毕之后/etc/syscofig/iptables文件就有了
