首先任意运行一条iptables防火墙规则配置命令如开通80端口:
) R8 v9 v' D& N" b
iptables -I INPUT 1 -p tcp --dport 80 -j ACCEPT
" O/ [9 ~. }4 K$ \7 R
然后对iptables服务进行保存:
* Z0 n# z9 N! Q% f0 @+ `5 Y8 S9 A/ ~
service iptables save
' R. e* t. T1 i$ s5 y- [( |6 {7 W
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.
, z2 B) c! f+ o+ w
解决方法:; g( _0 f! e' o0 \6 J# z" G a5 ^
systemctl stop firewalld 关闭防火墙
6 U \: Z& _" \& f/ {$ ~6 }yum install iptables-services 安装或更新服务
1 a& S5 l4 X5 C6 ?0 t
再使用systemctl enable iptables 启动iptables
0 J# [+ d7 b; x# _' U% R- N( h) R最后 systemctl start iptables 打开iptables
+ P2 z$ `- O$ u
再执行service iptables save 0 M0 z2 L! P( o9 x7 R5 b3 |
然后重启iptables服务:
3 I6 {2 a) J5 H2 _/ i2 b8 q
service iptables restart
# [ G- A' Q9 J9 h9 Z6 j2 f
执行完毕之后/etc/syscofig/iptables文件就有了 5 B# c6 o3 }1 w; Q
