10.21 firewalld关于zone的操做

Linux防火墙-firewalld

• firewall-cmd --set-default-zone=work //设定默认zone
• firewall-cmd --get-zone-of-interface=ens33 //查指定网卡
• firewall-cmd --zone=public --add-interface=lo //给指定网卡设置zone
• firewall-cmd --zone=dmz --change-interface=lo //针对网卡更改zone
• firewall-cmd --zone=dmz --remove-interface=lo //针对网卡删除zone
• firewall-cmd --get-active-zones //查看系统全部网卡所在的zone

firewall-cmd设定默认zone

• firewall-cmd --set-default-zone=work //设定默认的zone

[root@hf-01 ~]# firewall-cmd --set-default-zone=work
success
[root@hf-01 ~]# firewall-cmd --get-default-zone
work
[root@hf-01 ~]#

firewall-cmd查看指定网卡

• firewall-cmd --get-zone-of-interface=ens16777736 //查指定网卡

[root@hf-01 ~]# firewall-cmd --get-zone-of-interface=eno16777736
work
[root@hf-01 ~]# firewall-cmd --get-zone-of-interface=lo
no zone
[root@hf-01 ~]#

• 如果后续添加的网卡ens36，显示no zone，就须要把eno16777736的网卡配置环境复制一份，命令为ens36，并修改配置文件，最后重启网络服务，在从新加载firewalld服务（systemctl restart firewalld），在来查看ens36的zone
  • 若仍是没有zone，咱们就去增长给ens36增长一个zone
    • firewall-cmd --zone=public --add-interface=ens36 //给指定网卡设置zone

[root@hf-01 ~]# firewall-cmd --get-zone-of-interface=ens36
no zone
[root@hf-01 ~]# cd /etc/sysconfig/network-scripts/
[root@hf-01 network-scripts]# ls

[root@hf-01 network-scripts]# cp /etc/sysconfig/network-scripts/ifcfg-eno16777736 /etc/sysconfig/network-scripts/ens36
[root@hf-01 network-scripts]# vi !$        //编辑配置文件

[root@hf-01 network-scripts]# systemctl restart network.service    //重启网络服务
[root@hf-01 network-scripts]# systemctl restart firewalld    //从新加载firewalld服务
[root@hf-01 network-scripts]# firewall-cmd --get-zone-of-interface=ens36    //查看ens36网卡的zone
no zone
[root@hf-01 network-scripts]# firewall-cmd --zone=work --add-interface=ens36    //给ens36网卡设置zone
success
[root@hf-01 network-scripts]# firewall-cmd --get-zone-of-interface=ens36    //查看ens36网卡的zone
work
[root@hf-01 network-scripts]#

firewall-cmd给指定网卡设置zone

• firewall-cmd --zone=public --add-interface=lo //给指定网卡设置zone

[root@hf-01 network-scripts]# firewall-cmd --zone=public --add-interface=lo    给lo网卡设置zone 
success
[root@hf-01 network-scripts]# firewall-cmd --get-zone-of-interface=lo
public
[root@hf-01 network-scripts]#

firewall-cmd给指定网卡设置zone

• firewall-cmd --zone=dmz --change-interface=lo //针对网卡更改zone

[root@hf-01 network-scripts]# firewall-cmd --get-zone-of-interface=lo
public
[root@hf-01 network-scripts]# firewall-cmd --zone=dmz --change-interface=lo    //针对网卡更改zone
success
[root@hf-01 network-scripts]# firewall-cmd --get-zone-of-interface=lo
dmz
[root@hf-01 network-scripts]#

firewall-cmd针对网卡删除zone

• firewall-cmd --zone=block --remove-interface=ens37 //针对网卡删除zone

[root@hf-01 network-scripts]# firewall-cmd --zone=block --change-interface=ens36    给ens36网卡设置zone 
success
[root@hf-01 network-scripts]# firewall-cmd --zone=block  --remove-interface=ens36    //针对ens36网卡删除zone 
success
[root@hf-01 network-scripts]# firewall-cmd --get-zone-of-interface=ens36
no zone
[root@hf-01 network-scripts]#

• 在remove删除zone后，恢复默认的zone——>本身在删除后，就显示no zone，而并非恢复默认的zone！！！

firewall-cmd查看系统全部网卡所在的zone

• firewall-cmd --get-active-zones //查看系统全部网卡所在的zone

[root@hf-01 network-scripts]# firewall-cmd --get-active-zones        //查看系统全部网卡所在的zone
dmz
  interfaces: lo
work
  interfaces: eno16777736
[root@hf-01 network-scripts]#
