firewalld的9个zone、firewalld关于zone的操作、firewalld关于service的操作

一、firewalld的9个zone

1. 启动firewalld

1. [[email protected] ~]# systemctl disable iptables                                                                   停止iptables

    Removed symlink /etc/systemd/system/basic.target.wants/iptables.service.             

2. [[email protected] ~]# systemctl stop iptables                                                                        停止iptables

3. [[email protected] ~]# systemctl enable firewalld                                                                   #启用firewalld

    Created symlink from /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service to /usr/lib/systemd/system/firewalld.service.

    Created symlink from /etc/systemd/system/multi-user.target.wants/firewalld.service to /usr/lib/systemd/system/firewalld.service.

4. [[email protected] ~]# systemctl start firewalld                                                                      #启动firewalld

2. firewall-cmd --get-zones     查看所有的zone,firewalld默认有9个zone，

[[email protected] ~]# firewall-cmd --get-zones                                     

block dmz drop external home internal public trusted work

 3. firewall-cmd --get-default-zone   查询默认的zone，默认zone为public

[[email protected] ~]#firewall-cmd --get-default-zone           

public

二、firewalld关于zone的操作

1. firewall-cmd --set-default-zone=             更改默认的zone

[[email protected] ~]# firewall-cmd --set-default-zone=work         #更改默认的zone为work

success

[[email protected] ~]# firewall-cmd --get-default-zone                    #可以查询到默认的zone已经变更为work

work

2. firewall-cmd --get-zone-of-interface=       查看网卡设置的zone

[[email protected] ~]# firewall-cmd --get-zone-of-interface=ens33

work

[[email protected] ~]# firewall-cmd --get-zone-of-interface=ens37           #如果显示no zone，那么可能就是网卡没有配置文件

no zone

3.firewall-cmd --zone=dmz --add-interface=              设置网卡的zone

[[email protected] network-scripts]# firewall-cmd --zone=dmz --add-interface=ens37    #设置网卡ens37的zone

The interface is under control of NetworkManager, setting zone to 'dmz'.

success

[[email protected] network-scripts]# firewall-cmd --get-zone-of-interface=ens37

dmz

4. firewall-cmd --zone=block --change-interface=    更改网卡的zone

[[email protected] network-scripts]# firewall-cmd --zone=block --change-interface=ens37    #更改网卡ens37的zone

The interface is under control of NetworkManager, setting zone to 'block'.

success

[[email protected] network-scripts]# firewall-cmd --get-zone-of-interface=ens37

block

5.firewall-cmd --zone=block --remove-interface=     针对网卡删除zone

[[email protected] network-scripts]# firewall-cmd --zone=block --remove-interface=ens37      #删除block zone里面的ens37

The interface is under control of NetworkManager, setting zone to default.

success

[[email protected] network-scripts]# firewall-cmd --get-zone-of-interface=ens37         #ens37的zone变为work，因为work是默认的zone

work

6. firewall-cmd --get-active-zones        查看系统所有网卡所在的zone

[email protected] network-scripts]# firewall-cmd --get-active-zones

work

  interfaces: ens33 ens37

三、 firewalld关于service的操作

1.  firewall-cmd --get-services         查看系统所有的services

[[email protected] network-scripts]# firewall-cmd --get-services

RH-Satellite-6 amanda-client amanda-k5-client bacula bacula-client bitcoin bitcoin-rpc bitcoin-testnet bitcoin-testnet-rpc ceph ceph-mon cfengine condor-collector ctdb dhcp dhcpv6 dhcpv6-client dns docker-registry dropbox-lansync elasticsearch freeipa-ldap freeipa-ldaps freeipa-replication freeipa-trust ftp ganglia-client ganglia-master high-availability http https imap imaps ipp ipp-client ipsec iscsi-target kadmin kerberos kibana klogin kpasswd kshell ldap ldaps libvirt libvirt-tls managesieve mdns mosh mountd ms-wbt mssql mysql nfs nrpe ntp openv*n ovirt-imageio ovirt-storageconsole ovirt-vmconsole pmcd pmproxy pmwebapi pmwebapis pop3 pop3s postgresql privoxy proxy-dhcp ptp pulseaudio puppetmaster quassel radius rpc-bind rsh rsyncd samba samba-client sane sip sips smtp smtp-submission smtps snmp snmptrap spideroak-lansync squid ssh synergy syslog syslog-tls telnet tftp tftp-client tinc tor-socks transmission-client vdsm vnc-server wbem-https xmpp-bosh xmpp-client xmpp-local xmpp-server

2.  firewall-cmd --list-service      查看当前默认的zone下有哪些service

[[email protected] network-scripts]# firewall-cmd --list-service

ssh dhcpv6-client

3.  firewall-cmd --zone=     --list-service     查看指定zone的service

[[email protected] network-scripts]# firewall-cmd --zone=public --list-service    #查看public zone里面的service

ssh dhcpv6-client

4.firewall-cmd --zone=zonename  --add-service= 服务名    将一个服务添加到一个zone里面

[[email protected] network-scripts]# firewall-cmd --zone=public --add-service=http    #将http服务添加到public zone里面

success

[[email protected] network-scripts]# firewall-cmd --zone=public --list-service           #可以看到添加成功

ssh dhcpv6-client http #将http服务添加到public zone里面

5. --permanent     将更改写入配置文件，不加这个参数只保存在内存中，没有写配置文件   /etc/firewalld/zones/public.xml

[[email protected] network-scripts]# firewall-cmd --zone=public --add-service=http --permanent         #在public zone里面添加http服务       

success

[[email protected] network-scripts]# cat /etc/firewalld/zones/public.xml            #查看配置文件

<?xml version="1.0" encoding="utf-8"?>

<zone>

  <short>Public</short>

  <description>For use in public areas. You do not trust the other computers on networks to not harm your computer. Only selected incoming connections are accepted.</description>

  <service name="ssh"/>

  <service name="dhcpv6-client"/>

  <service name="http"/>

</zone>

6.模板文件的放置地址

zone的配置文件放置在/etc/firewalld/zones这个目录下。

service的配置文件放置在 /etc/firewalld/service目录下。

zone的模板文件放置在 /usr/lib/firewalld/zones 下  

service 的模板文件放置在/usr/lib/firewalld/service下

7. 需求：ftp服务自定义端口1121，需要在work zone下面放行ftp

1. [[email protected] ~]# cp /usr/lib/firewalld/services/ftp.xml /etc/firewalld/services/ftp.xml           # 拷贝ftp service的配置模板

2. [[email protected] ~]# vim /etc/firewalld/services/ftp.xml                                              # 编辑配置文件，自定义端口1121

                  <port protocol="tcp" port="1121"/>

3. [[email protected] ~]# cp /usr/lib/firewalld/zones/home.xml /etc/firewalld/zones/home.xml               # 拷贝home zone的配置模板

4. [[email protected] ~]# vim /etc/firewalld/zones/home.xml                                                   # 编辑home的配置文件，将<service name="ftp"/>这一行添加上去

                <service name="ftp"/>

5. [[email protected] ~]# firewalld --reload                                                                                 # 重新加载firewald服务

6. [[email protected] ~]# firewall-cmd --zone=home --list-service                                          # 查看ftp service在home zone里是否添加成功

    ssh mdns samba-client dhcpv6-client ftp
