This article will explain in detail how to install bind on DNS. The content of the article is of high quality, so the editor shares it for you as a reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

Four test servers: mail, www, master dns, slave DNS

Main DNS: 192.168.1.27

Www: 192.168.1.28

Mail: 192.168.1.29

From DNS: 192.168.1.34

Install bind on master and slave dns

Yum install bind

Configure DNS by using the newly created configuration file

The following operations are implemented on the main DNS

1. Type the original configuration file as bak

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

2. Rebuild the main configuration file named.conf

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

Options {

Directory "/ var/named"

}

Zone "." IN {# Root Resolution

Type hint

File "named.ca"; # root parse file path

}

Zone "localhost." IN {# Native forward parsing

Type master

File "named.localhost"; # File path for native forward parsing

}

Zone "1.0.0.127.in-addr.arpa." IN {# Native reverse parsing

Type master

File "named.loopback"; # File path for local reverse parsing

}

3. Modify the master group and permissions of / etc/named.conf

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

[root@localhost ~] # chmod 640 / etc/named.conf

4. Check the configuration file for syntax errors

[root@localhost ~] # service named configtest

Zone localhost/IN: loaded serial 0

Zone 1.0.0.127.in-addr.arpa/IN: loaded serial 0

5. Start the named service

[root@localhost ~] # service named start

Generating / etc/rndc.key: [OK]

Start named: [OK]

6. Add zones to the configuration file / etc/named.conf

Zone "shamereedwine.com." IN {

Type master

File "shamereedwine.com.zone"

}

7. Create a zone file shamereedwine.com.zone

In the cd / var/named directory

Vim shamereedwine.com.zone

$TTL 600

@ IN SOA dns.shamereedwine.com. Admin.shamereedwine.com. (

2017061801

2H

10M

7D

1D)

@ IN NS dns

@ IN MX 10 mail

Dns IN A 192.168.1.27

Mail IN A 192.168.1.29

Www IN A 192.168.1.28

Pop IN CNAME mail

Ftp IN CNAME www

8. Modify the group and owner of the area file shamereedwine.com.zone

[root@localhost named] # chown root:named shamereedwine.com.zone

[root@localhost named] # chmod 640 shamereedwine.com.zone

9. Check for grammatical errors

[root@localhost named] # service named configtest

Zone localhost/IN: loaded serial 0

Zone 1.0.0.127.in-addr.arpa/IN: loaded serial 0

Zone shamereedwine.com/IN: loaded serial 2017061801

10. Restart named service

[root@localhost named] # service named restart

Stop named:. [OK]

Start named: [OK]

11. Use dig command to test dns parsing

[root@localhost named] # dig-t NS shamereedwine.com

; DiG 9.8.2rc1-RedHat-9.8.2-0.62.rc1.el6_9.2-t NS shamereedwine.com

8. Configure reverse parsing configuration file

Vim / etc/named.rfc1912.zones

Add the reverse parsing area parameters shown below

Zone "1.168.192.in-addr.arpa" IN {

Type master

File "192.168.1.zone"

}

9. Configure reverse parsing zone files

Cd / var/named

Vim 192.168.1.zone

$TTL 600

@ IN SOA dns.shamereedwine.com. Dnsadmin.shamereedwine.com. (

2017061801

1H

5M

3D

12H)

IN NS dns.shamereedwine.com.

27 IN PTR dns.shamereedwine.com.

28 IN PTR www.shamereedwine.com.

29 IN PTR mail.shamereedwine.com.

Chown root:named 192.168.1.zone # change ownership and group

Chmod 640 192.168.1.zone # set permissions

10. Test the correctness of the main configuration file and area file

Service named configtest

Zone localhost.localdomain/IN: loaded serial 0

Zone localhost/IN: loaded serial 0

Zone 1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa/IN: loaded serial 0

Zone 1.0.0.127.in-addr.arpa/IN: loaded serial 0

Zone 0.in-addr.arpa/IN: loaded serial 0

Zone shamereedwine.com/IN: loaded serial 2017061801

Zone 1.168.192.in-addr.arpa/IN: loaded serial 2017061801

11. Restart service

Service named reload

12. Test reverse parsing # parsing 192.168.1.27

[root@dns named] # dig-x 192.168.1.27

; DiG 9.8.2rc1-RedHat-9.8.2-0.62.rc1.el6_9.2-x 192.168.1.27
