# Yum install-y bind * caching-nameserver


2. Open firewall ports
# 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. Disable selinux
# Vi/etc/selinux/config
SELINUX = disabled

# Vi/etc/named. conf

listen-on port 53 { any; };listen-on-v6 port 53 { any; };allow-query     { any; };

5. Add the domain to the bind main configuration file.

# 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 the zone File
# Vi baidu.com. zone
$TTL 86400@       IN SOA          ns.baidu.com. root (                                        1       ; serial                                        1D      ; refresh                                        1H      ; retry                                        1W      ; expire                                        3H )    ; minimum@       IN      NS      ns.baidu.com.ns      IN      A       115.239.211.110www     IN      A       115.239.211.110

# Vi doiido.com. zone
$TTL 86400@       IN SOA          ns.doiido.com. root (                                        1       ; serial                                        1D      ; refresh                                        1H      ; retry                                        1W      ; expire                                        3H )    ; minimum@       IN      NS      ns.doiido.com.ns      IN      A       1.1.1.1www     IN      A       1.1.1.1

# Vi 1.10.zone
$TTL 86400@       IN SOA           ns.doiido.com. ns.baidu.com. (                                        12         ; serial                                        28800      ; refresh                                        14400      ; retry                                        3600000    ; expire                                        86400 )    ; minimum@        IN      NS       ns.doiido.com.1        IN      PTR      www.doiido.com.110      IN      PTR      www.baidu.com.
