Experiment Configuration

It is recommended to close iptables and SELinux first

[email protected] ~]# mount/dev/cdrom/mnt //Mount CD to the MNT directory

Mount:block Device/dev/sr0 is write-protected, mounting read-only

[Email protected] ~]#

Installing the DNS Package

[Email protected] ~]# rpm-ivh/mnt/packages/bind-9.8.2-0.17.rc1.el6_4.6.x86_64.rpm

Modify the main distribution file, the master profile only needs to modify the optins{} entry

[Email protected] ~]# vi/etc/named.conf

650) this.width=650; "src=" Http://s5.51cto.com/wyfs02/M00/79/BF/wKioL1aaR8Hx5Bq8AAEh99IYhhE457.png "title=" 5fg_ z8v%wyexlq}b{p0$}) 0.png "alt=" Wkiol1aar8hx5bq8aaeh99iyhhe457.png "/>

Modifying a zone configuration file

[Email protected] ~]# Vi/etc/named.rfc1912.zones

The forward zone configuration file format is zone{};

Add a reverse region at the end of the configuration file with the same format as the forward region

Modify a record file

[[email protected] ~]# cd/var/named/ //The directory where the switch value record file is located

Copy the configuration template, record files for the forward zone, and reverse zone record files. "-P" preserves the file attributes,

[Email protected] named]# cp-p named.localhost test.com.zone

[Email protected] named]# cp-p named.localhost test.com.local

[Email protected] named]# vim Test.com.zone

Experimental environment

Then the above experiment starts a centos6.5 virtual machine to do from the server

Experiment Configuration

Configuring the primary server

To modify the server's zone configuration file

[Email protected] ~]# Vim/etc/named.rfc1912.zones

Only need to add the following 2 lines in the original configuration file, forward parsing
