DNS正向解析和

1.挂载

[root@localhost ~]# mount /dev/sr0 /mnt
2.安装bind软件包

[root@localhost ~]# yum install bind -y

3.关闭防火墙

[root@localhost ~]# systemctl disable firewalld --now
[root@localhost ~]# setenforce 0

4.在配置文件里编辑

[root@localhost ~ named]# vim /etc/named.conf
options {
listen-on port 53 192.168.61.129; };
directory "var/named";
allow-query {localhost;};
};
logging {
channel default debug {
file "data/named.run";
severity dynamic;
};
zone"openlab.com" IN {
type master;
file "named.openlab .com";
};
zone "88.168.192.in-addr.arpa" IN [
type master;
file"named.openlab .com";
};

5.更改/var/named/named.openlab.com文件和/etc/resolv.conf文件

[root@localhost ~]# vim /var/named/named.openlab.com

@ IN SOA ns.openlab.com. admin.qq.com. (
2023051002
1M
1M
1M
3M )
NS ns.openlab.com.
ns A 192.168.61.131
ftp A 192.168.61.132
www A 192.168.61.133
http CNAME www

[root@localhost ~]# vim /etc/resolv.conf

# Generated by NetworkManager
search localdomain
nameserver 192.168.88.129

6.测试

[root@localhost ~]# host www.openlab.com
www.openlab.com has address 192.168.61.133

二.DNS反向解析
1.安装bind

[root@localhost ~]# yum install bind -y

2.关闭防火墙

[root@localhost ~]# systemctl disable firewalld --now
[root@localhost ~]# setenforce 0
3.更改配置文件/etc/name.conf

[root@localhost ~]# vim /etc/named.conf

options {
listen-on port 53 { 192.168.61.131; };
directory "/var/named";
allow-query { any; };
recursion yes;
};

#正向解析
zone "openlab.com" IN {
type master;
file "named.openlab.com";
};

#反向解析
zone "88.168.192.in-addr.arpa" IN {
type master;
file "named.openlab.com";
};

4.更改/var/named/named.openlab.com文件和/etc/resolv.conf文件

[root@localhost ~]# vim /var/named/named.openlab.com

$TTL 1D
@ IN SOA ns.openlab.com. admin.qq.com. (
2023051002
1M
1M
1M
3M )
NS ns.openlab.com.
ns A 192.168.61.131
ftp A 192.168.61.132
www A 192.168.61.133
http CNAME www
130 PTR ns.openlab.com.
131 PTR www.openlab.com.
132 PTR ftp.openlab.com.

[root@localhost ~]# vim /etc/resolv.conf

# Generated by NetworkManager
search localdomain
nameserver 192.168.61.128

5.客户端测试，反向测试结果如下：

[root@localhost ~]# nslookup 192.168.61.132
132.61.168.192.in-addr.arpa   name = ftp.openlab.com.

[root@localhost ~]# nslookup 192.168.61.133
133.61.168.192.in-addr.arpa   name = www.openlab.com.

[root@localhost ~]# nslookup 192.168.61.131
131.61.168.192.in-addr.arpa   name = ns.openlab.com
