实验环境:OS: RHEL6
Master DNS: 10.167.27.193
Slave DNS: 10.167.27.91
一、Rpm
1、软件包的安装
rpm -ivh bind-9.3.
rpm -ivh bind-utils
rpm -ivh caching-nameserver
2、配置文件的修改
修改named.conf文件,添加域zhang.com的正向反向解析!
vi /etc/named.conf
zone "zhang.com" IN {
type master;
file "zhang.zone";
allow-update { none; };
allow-transfer { 10.167.27.91;}; ##这一行表示允许10.167.27.91复制,如果不做slave可以去掉!
notify yes; ###开启通告,有更新就会通告给从服务器
also-notify{ 10.167.27.91;};
};
zone "27.167.10.in-addr.arpa" IN {
type master;
file "zhang.local";
allow-update { none; };
allow-transfer { 10.167.27.91;}; ##同上
notify yes; ###开启通告,有更新就会通告给从服务器
also-notify{ 10.167.27.91;};
};
3、
(1) cp /var/named/named.local /var/named/chroot/var/named/zhang.local
(2) cp /var/named/named.zone /var/named/chroot/var/named/zhang.zone
(3) chown named.named /var/named/chroot/var/named/zhang.*
ln -s /var/named/chroot/var/named/zhang.zone /var/named/zhang.zone
ln -s /var/named/chroot/var/named/zhang.local /var/named/zhang.local
###后面两步步做也可以,知识为了以后更好更改!
4、 修改zhang.zone文件的内容:
[root@localhost named]# vi /var/named/zhang.zone
$TTL 86400
@ IN SOA zhang.com. root.zhang.com. (
1997022700 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ) ; Minimum
@ IN NS zhang.com.
www IN A 10.167.27.91
5、 修改zhang.local文件的内容:
[root@localhost named]# vi /var/named/zhang.local
$TTL 86400
@ IN SOA zhang.com. root.zhang.com. (
1997022700 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ) ; Minimum
@ IN NS zhang.com.
91 IN PTR www.zhang.com.
6、/etc/rc.d/init.d/named restart
7、测试
[root@localhost named]# vi /etc/resolv.conf
nameserver 10.167.27.193
service network restart
host www.zhang.com
nslookup www.zhang.com
二、Slave DNS的配置
zone "zhang.com" IN {
type slave;
file "slaves/zhang.zone";
masters { 10.167.27.193; }; ##指定从服务器的地址
};
zone "27.167.10.in-addr.arpa" IN {
type slave;
file "slaves/zhang.local";
masters { 10.167.27.193; }; ##同上!
};
