Preparatory work:

Prepare 3 servers:

Http server:192.168.1.3

Dns server: 192.168.1.4

Dns client:192.168.1.5

3 servers, DNS and HTTP services should be turned on in the firewall

1. Simply build a http service on the http server for testing

(1) yum-y install httpd

(2) [root@client Desktop] # echo "welcome to china test" > / var/www/html/index.html

[root@client Desktop] # systemctl restart httpd

[root@client Desktop] # systemctl enable httpd

two。 Install the dns service on the dns server and configure the dns master configuration file

Here three places are changed to: any

3. Create a domain tianyun.com in the main configuration file and add 4 lines of code:

Zone "tianyun.com" {

Type master

File "tianyun.com.zone"

}

4. Edit zone configuration file: vim / var/named/tianyun.com.zone

@ IN SOA dns root (2020030700 1H 15m 1W 1D)

@ IN NS dns

Dns IN A 192.168.1.4

Www IN A 192.168.1.3

@ indicates the current domain name

IN:internet

Www.tianyun.com=www

SOA: starting authorization record mandatory

NS:DNS server record enforcement

A: host record

CNAME: alias record

2020030700: update serial number

1H update time 1 hour

15m retry delay 15 minutes

1W failure time 1 week

1D invalid resolution record cache time 1 day

[root@dns-server Desktop] # systemctl restart named restart service

5. test

Change the DNS of the http sever service to: 192.168.1.4

[root@http-sever Desktop] # vim / etc/resolv.conf

Nameserver 192.168.1.4

When ping www.tianyun.com, automatically parse to 192.168.1.3, so the experiment is successful.
