主从DNS配置流程示例

实验环境：主服务器A：10.1.1.6
从服务器B：10.1.1.5
1.安装DNS域名解析服务
#yum install bind-* -y
2.主服务器A配置：
#vim /var/named/chroot/etc/named.conf
options {
directory "/var/named";
allow-recursion {10.1.1.5/24; };
};
#zone "." IN {
# type hint;
# file "named.ca";
#};
#zone "localost" IN {
# type master;
# file "named.localhost";
# allow-transfer {none; };
#};
#zone "0.0.127.in-addr.arpa" IN {
# type master;
# file "named.loopback";
# allow-transfer {none; };
#};
zone "swht.com" IN {
type master;
file "swht.com.zone";
# masters {10.1.1.6; };
allow-transfer {10.1.1.5; };
};
zone "1.1.10.in-addr.arpa" IN {
type master;
file "10.1.1.zone";
allow-transfer {10.1.1.5; };
};
#chmod 640 /var/named/chroot/etc/named.conf 修改文件的权限
#chown root:named /var/named/chroot/etc/named.conf 修改文件的属组
#vim /var/named/chroot/var/named/swht.com.zone
$TTL 600
@ IN SOA master.swht.com. root (
2014091901
1H
5M
2D
6H)
IN NS master
IN MX 10 mail
master IN A 10.1.1.6
mail IN A 10.1.1.6
www IN A 10.1.1.6
ftp IN CNAME www
#chmod 640 /var/named/chroot/var/named/swht.com.zone
#chown root:named /var/named/chroot/var/named/swht.com.zone
#vim /var/named/chroot/var/named/10.1.1.zone
$TTL 600
@ IN SOA master.swht.com. root (
2014091901
1H
5M
2D
6H)
IN NS master
6 IN PTR master
6 IN PTR mail
6 IN PTR www
6 IN PTR ftp
#chmod 640 /var/named/chroot/var/named/10.1.1.zone
#chown root:named /var/named/chroot/var/named/10.1.1.zone
#service named restart
3.从服务器B配置：
#vim /var/named/chroot/etc/named.conf
options {
directory "/var/named";
allow-recursion {10.1.1.6/26; };
notify yes;
};
#zone "." IN {
# type hint;
# file "named.ca";
#};
#zone "localost" IN {
# type master;
# file "named.localhost";
# allow-transfer {none; };
#};
#zone "0.0.127.in-addr.arpa" IN {
# type master;
# file "named.loopback";
# allow-transfer {none; };
#};
zone "swht.com" IN {
type slave;
file "slaves/swht.com.zone";
masters {10.1.1.6; };
};
zone "1.1.10.in-addr.arpa" IN {
type slave;
file "slaves/10.1.1.zone";
masters {10.1.1.6; };
};
#chmod 640 /var/named/chroot/etc/named.conf
#chown root:named /var/named/chroot/etc/named.conf
#service named restart
4.验证：
#dig -t NS www.swht.com
#host 10.1.1.6
#cd /var/named/chroot/var/named/slaves
#ls
10.1.1.zone swht.com.zone
#vim 10.1.1.zone
$ORIGIN .
$TTL 600 ; 10 minutes
1.1.10.in-addr.arpa IN SOA master.swht.com. root.1.1.10.in-addr.arpa. (

3600 ; refresh (1 hour)
300 ; retry (5 minutes)
172800 ; expire (2 days)
21600 ; minimum (6 hours)
)

#vim swht.com.zone
