1. Install related packages
# yum Install-y bind* Caching-nameserver


2. Firewall Port Open
# Vi/etc/sysconfig/iptables
-ainput-m State--state new-m tcp-p TCP--dport 53-j ACCEPT
-ainput-m State--state new-m udp-p UDP--dport 53-j ACCEPT
-ainput-m State--state new-m tcp-p TCP--dport 953-j ACCEPT

# Service Iptables Restart
#/etc/rc.d/init.d/iptables Save


3. Turn off SELinux
# Vi/etc/selinux/config
Selinux=disabled


4. Modify Named.conf
# vi/etc/named.conf

Listen-on Port: (any;}; LISTEN-ON-V6 Port: (any;}; Allow-query     {any;};

5. Add the domain in the main configuration file of bind

# Vi/etc/named.rfc1912.zones

Zone "baidu.com" in{    type master;    File "Baidu.com.zone";}; Zone "doiido.com" in{    type master;    File "Doiido.com.zone";}; Zone "1.10.in-addr.arpa" in {    type master;    File "1.10.zone";};

6. Create a zone file for the domain
(The file name here must be the same as above)
# cd/var/named
# Touch Baidu.com.zone
# Touch Doiido.com.zone
# Touch 1.10.zone


7. Edit Zone File
# VI Baidu.com.zone

8. Modify the permissions of the domain file you just added
# chmod o+r/var/named/*


9. Modify the resolv.conf file
# vi/etc/resolv.conf
NameServer 192.168.100.100


10. Test the configuration file
# Named-checkzone Doiido.com/var/named/doiido.com.zone
# Named-checkzone Baidu.com/var/named/baidu.com.zone


11. Restart the named service

# Service named restart
