防火墙的开启与关闭
?
centos7的防火墙设置和以前不一样了,一定要注意。</br>
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|start|restart] iptables
Saving your firewall rules can be done as follows:
service iptables save
or
/usr/libexec/iptables/iptables.init save
2.开启端口
开启端口
firewall-cmd --zone=public --add-port=80/tcp --permanent
命令含义:
--zone #作用域
--add-port=80/tcp #添加端口,格式为:端口/通讯协议
--permanent #永久生效,没有此参数重启后失效
重启防火墙
firewall-cmd --reload
