架設 DNS for CentOS 5

我示範的版本是 CentOS 5，當然也適用於 RHLE 5

安裝這些套件 bind，bind-chroot，bind-utils，system-config-bind
# yum -y install bind bind-chroot bind-utils system-config-bind

拷貝 named.conf 示範檔到 /var/named/chroot/etc/
# cp /usr/share/system-config-bind/profiles/default/named.conf /var/named/chroot/etc/

編輯一下 named.conf
# vi /var/named/chroot/etc/named.conf

options {
directory “/var/named”
dump-file “/var/named/data/cache_dump.db”
statistics-file “/var/named/data/named_stats.txt”
forwarders { 168.95.1.1; 139.175.10.20; };
allow-query { any; };

};

zone “.” IN {
type hint;
file “named.root”
};

zone “localdomain.” IN {
type master;
file “localdomain.zone”
allow-update { none; };
};

zone “localhost.” IN {
type master;
file “localhost.zone”
allow-update { none; };
};

zone “0.0.127.in-addr.arpa.” IN {
type master;
file “named.local”
allow-update { none; };
};

zone “vblog.tw” IN {
type master;
file “vblog.tw.zone”
allow-update { none; };
};

include “/etc/rndc.key”

拷貝 localdomain.zone，localhost.zone，named.local，這些預設檔案到 /var/named/chroot/var/named/
# cd /usr/share/system-config-bind/profiles/default/named
# cp localdomain.zone localhost.zone named.local /var/named/chroot/var/named/

拷貝 named.root 這個重要檔案到 /var/named/chroot/var/named/
# cp /usr/share/doc/bind-9.3.3/sample/var/named/named.root /var/named/chroot/var/named/

再來就設定自已網域設定檔
# cd /var/named/chroot/var/named
# vi vblog.tw.zone
