This article mainly explains "the process of DNS forward parsing and master-slave replication script". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "the process of DNS forward parsing and master-slave copying scripts".

#! / bin/bash

# Test whether to install bind

[!-f / etc/named.conf] & & echo "DNS service is not installed, install now" & & yum-y install bind & > / dev/null

Echo "DNS package installed!"

# modify the main configuration file

Sed-ri's etc/named.conf 127.0.0.1 etc/named.conf 192.168.220.146

Sed-ri'/ allow-query/s/localhost/any/' / etc/named.conf

# modify zone configuration and zone configuration data file

[- f / etc/named.rfc1912.zones] & & cp / etc/named.rfc1912.zones / etc/named.rfc1912.zones.bak

While:; do

Read-p "Please enter the domain name:" a

Read-p "Zone data profile name:" b

Echo "

Zone\ "$a\" IN {

Type master

File\ "$b\"

Allow-update {none;}

}; "> > / etc/named.rfc1912.zones

Cp-p / var/named/named.localhost / var/named/$b

Sed-I '910d' / var/named/$b

Sed-I "/ SOA/s/A.*\. / A $a. Admin.$a./" / var/named/$b

Sed-I "/ NS/s/@/$a\. /" / var/named/$b

Read-p "Please enter the domain name resolution address:" e

Echo "A $e" > > / var/named/$b

While:; do

Echo-n "Please enter the hostname + IP address (for example: www 192.168.100.100 is divided by spaces, enter Q to exit):"

Read q w

If [$Q = "Q"]; then

Break

Else

Echo "$q IN A $w" > > / var/named/$b

Fi

Done

Read-p "whether to enter the next resolution domain name (enter to continue):" d

[! $d = ""] & & break

Done

Systemctl status named

If [$?-eq 0]; then

Systemctl restart named

Else

Systemctl start named

Fi

Systemctl stop firewalld.service
