centos下/etc/sysconfig/下找不到iptables文件

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
异常
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.
It is possible to go back to a more classic iptables setup. First, stop and mask the firewalld service:
[html] view plain copy
systemctl stop firewalld
systemctl mask firewalld
Then, install the iptables-services package:
[html] view plain copy
yum install iptables-services
Enable the service at boot-time:
[html] view plain copy
systemctl enable iptables
Managing the service
[html] view plain copy
systemctl stop iptables
systemctl start iptables
systemctl |restart iptables
Saving your firewall rules can be done as follows:
[html] view plain copy
service iptables save
or
[html] view plain copy
/usr/libexec/iptables/iptables.init save
