解决CentOS出现Unit iptables.service failed to load

一直用CentOS 6 习惯了,一下没适应过来。防火墙配置后执行service iptables save 出现”Failed to restart iptables.service: Unit iptables.service failed to load: No such file or directory.”错误,在CentOS 7或RHEL 7或Fedora中防火墙由firewalld来管理,当然你可以还原传统的管理方式。或则使用新的命令进行管理。

假如采用传统请执行一下命令:

 
1
2
systemctl stop firewalld
systemctl mask firewalld

 

并且安装iptables-services:

 
1
yum install iptables-services

设置开机启动:

 
1
systemctl enable iptables

 

 
1
2
3
systemctl [stop|start|restart] iptables
#or
service iptables [stop|start|restart]

 

 
1
2
3
service iptables save
#or
/usr/libexec/iptables/iptables.init save
