你没看明白我的问题
-------------------------------
没有 iptables 这个服务
我也不知道 oracle 怎么魔改的系统
[root@okx2 ~]# service iptables save
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.
[root@okx2 ~]# service iptables reload
Redirecting to /bin/systemctl reload iptables.service
Failed to reload iptables.service: Unit iptables.service not found.
