防火墙命令(iptables)命令# systemctl restart iptables.service失效

 

Redirecting to /bin/systemctl restart iptables.ser

linux下执行防火墙相关指令报错:

Redirecting to /bin/systemctl restart iptables.service

1,安装systemctl:

yum install iptables-services

2,设置开机启动:

systemctl enable iptables.service

然后就可以执行以下指令了:

systemctl stop iptables
systemctl start iptables
systemctl restart iptables
systemctl reload iptables




CentOS 7.0默认使用的是firewall作为防火墙,这里改为iptables防火墙。
1、关闭firewall:

systemctl stop firewalld.service
systemctl disable firewalld.service
systemctl mask firewalld.service
2、安装iptables防火墙

yum install iptables-services -y
3.启动设置防火墙

systemctl enable iptables
systemctl start iptables

4.查看防火墙状态

systemctl status iptables
5编辑防火墙,增加端口

vi /etc/sysconfig/iptables #编辑防火墙配置文件
 

-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT

:wq! #保存退出

3.重启配置,重启系统

systemctl restart iptables.service #重启防火墙使配置生效
systemctl enable iptables.service #设置防火墙开机启动
