原因:在新安装的Linux系统中,防火墙默认是被禁掉的,一般也没有配置过任何防火墙的策略,所有不存在/etc/sysconfig/iptables文件。
解决办法:
1、随便写一条iptables命令配置个防火墙规则:如:
iptables -P OUTPUT ACCEPT
2,进行保存
service iptables save
3,service iptables restart

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.
解决
With RHEL 7 / CentOS 7, firewalld was introduced to manage iptables. IMHO, firewalld is more suited for workstations than for server environments.

systemctl stop firewalld
systemctl mask firewalld
Then, install the iptables-services package:
Enable the service at boot-time:
Managing the service
Saving your firewall rules can be done as follows:
