firewalld的基本使用
启动: systemctl start firewalld

查看状态: systemctl status firewalld
自启: systemctl enable firewalld
禁用: systemctl disable firewalld
启动一个服务:systemctl start firewalld.service
关闭一个服务:systemctl stop firewalld.service
重启一个服务:systemctl restart firewalld.service
显示一个服务的状态:systemctl status firewalld.service
在开机时启用一个服务:systemctl enable firewalld.service
在开机时禁用一个服务:systemctl disable firewalld.service
查看服务是否开机启动:systemctl is-enabled firewalld.service
查看已启动的服务列表:systemctl list-unit-files|grep enabled
查看启动失败的服务列表:systemctl –failed
配置firewalld-cmd
查看版本: firewall-cmd –version
查看帮助: firewall-cmd –help
显示状态: firewall-cmd –state
查看所有打开的端口: firewall-cmd –zone=public –list-ports
更新防火墙规则: firewall-cmd –reload
查看区域信息: firewall-cmd –get-active-zones
查看指定接口所属区域: firewall-cmd –get-zone-of-interface=eth0
拒绝所有包: firewall-cmd –panic-on
取消拒绝状态: firewall-cmd –panic-off
查看是否拒绝: firewall-cmd –query-panic
开启端口
firewall-cmd –zone=public –add-port=8080/tcp –permanent (–permanent永久生效,没有此参数重启后失效)
重新载入
firewall-cmd –reload
查看
firewall-cmd –zone= public –query-port=80/tcp
删除
firewall-cmd –zone= public –remove-port=80/tcp –permanent
开启端口区间
开启后需要重启服务
firewall-cmd --permanent --zone=public --add-port=100-500/tcp
firewall-cmd --permanent --zone=public --add-port=100-500/udp
firewall-cmd --reload
