centos下/etc/sysconfig/下找不到iptables檔案
阿新 • • 發佈:2019-02-05
原因:在新安裝的Linux系統中,防火牆預設是被禁掉的,一般也沒有配置過任何防火牆的策略,所有不存在/etc/sysconfig/iptables檔案。
解決辦法:
1、隨便寫一條iptables命令配置個防火牆規則:如:
iptables -P OUTPUT ACCEPT
2,進行儲存
service iptables save
3,service iptables restart
異常
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.
解決
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:
systemctl stop firewalld systemctl mask firewalld
Then, install the iptables-services package:
yum install iptables-services
Enable the service at boot-time:
systemctl enable iptables
Managing the service
systemctl stop iptables
systemctl start iptables
systemctl |restart iptables
Saving your firewall rules can be done as follows:
service iptables save
or
/usr/libexec/iptables/iptables.init save
