一、正向解析
1.下载DNS软件包
[root@www ~]# yum indtall -y bind
注意：
下载软件前需要配置仓库，挂载
[root@www ~]# cd /etc/yum.repos.d/
[root@www ~]# vi rpm.repo仓库内容：
[BaseOS]
name=BaseOS
baseurl=/mnt/BaseOS
enable=1
gpgcheck=0
[AppStream]
name=AppStream
baseurl=/mnt/AppStream
enable=1
gpgcheck=0[root@www ~]# mkdir /mnt
[root@www ~]# mount /dev/sr0 /mnt需要在虚拟机中勾选“已连接”，否则挂载不成功
2.修改主配置文件
[root@www ~]# vim /etc/named.conf
options {listen-on port 53 { 192.168.198.142; };directory "/var/named";
};
zone "." IN {type hint;file "named.ca";
};
zone "haha.com." IN {type master;file "named.haha";
};
zone "198.168.192.in-addr.arpa" IN {type master;file "fanxiang";
};
3.创建区域文件
[root@www ~]# vim /var/named/named.haha
$TTL 1d
@ IN SOA @ admin.haha.com. ( 20240706011111)IN NS ns.haha.com.IN MX 10 mail.haha.com.
ns IN A 192.168.198.142
mail IN A 192.168.198.38
www IN A 192.168.198.140
ftp IN CNAME www
4.配置DNS
[root@www ~]# nmcli connection modify ens160 ipv4.dns 192.168.198.2
[root@www ~]# nmcli connection up ens160
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/5)
[root@www ~]# nmcli device show | grep DNS
IP4.DNS[1]: 192.168.198.2
5.测试
[root@www ~]# dig -t NS haha.com ; <<>> DiG 9.16.23-RH <<>> -t NS haha.com

1.修改主配置文件
[root@www ~]# vim /etc/named.conf
options {listen-on port 53 { 192.168.198.142; };directory "/var/named";forward only;forwarders { 61.134.1.4; };
};
zone "." IN {type hint;file "named.ca";
};
zone "haha.com." IN {type master;file "named.haha";
};
zone "198.168.192.in-addr.arpa" IN {type master;file "fanxiang";
};
2.创建区域文件
[root@www ~]# vim /var/named/named.haha
$TTL 1d
@ IN SOA @ admin.haha.com. ( 20240706011111)IN NS ns.haha.com.IN MX 10 mail.haha.com.
139 IN PTR ns.haha.com.
38 IN PTR mail.haha.com.
140 IN PTR www.haha.com.
140 IN PTR ftp.haha.com.
3.测试
