错误信息如下:
- service iptables start
- Redirecting to /bin/systemctl start iptables.service
- Failed to start iptables.service: Unit iptables.service failed to load: No such file or directory.
- 解决方法如下:
因为centos7默认的防火墙是firewalld防火墙管理工具,不是使用iptables。因此需要先关闭firewalld服务,或者使用默认的firewalld防火墙。
(1)关闭firewalld:
systemctl stop firewalld
systemctl mask firewalld
(2) 使用iptables服务:
1.安装iptables-services:
yum install iptables-services
2.设置开机启动:
- systemctl enable iptables
-
3. iptables启动、关闭、保存:
- systemctl [stop|start|restart] iptables
- #or
- service iptables [stop|start|restart]
-
-
- service iptables save
- #or
- /usr/libexec/iptables/iptables.init save
