DNS setup for Linux

Install the bind package with Yum First (this package is the installation package for DNS)

Then close SELinux

Setenforce 0

After emptying the firewall

Iptables-f

After the installation is complete only

Vim to/etc/named.conf

Modify Options Area after entry

This is before the change.

This is how it's changed.

Then modify the Named.rfc1912.zones file, vi/etc/named.rfc1912.zones this file

Only these two areas are reserved for forward parsing and reverse parsing

Then modify the content as follows forward parsing area The domain I wrote is the zbl.com file name Zbl.localhost

Reverse parse 216.168.192 filename into zbl.loopback

Then modify the localhost configuration file,

Forward parsing:

CD to Directory

cd/var/named/

Copy files with attributes

Cp-p Named.localhost Zbl.localhost

Edit Zbl.localhost File

VI Szlpt.cn.zone

At first it was like this

I modified it after this is the DNS. Referring to my native mail mail service refers to another www pointing to itself

Reverse parsing:

CD to Directory

cd/var/named/

Copy template file with attribute copy

Cp-p Name.loopback Zbl.loopback

Edit File Zbl.loopback

Vim Zbl.loopback

After modification

The Restart DNS service is:

Service named restart

The Shutdown DNS service is:

Service named stop

The DNS service is turned on:

Service named start

Just restart here.

Then edit the NIC configuration file to point DNS to your own local resolution to do the experiment

Vim/etc/sysconfig/network-scripts/ifcfg-eth0

dns1= DNS native 115

Then restart the NIC

Service Network restart

Under test

Nslookup
