テストサーバーを構築した時のメモ。CentOS5.4 。公開サーバーではないので、外部向けの設定は行っていません。
インストール
[root@centos ~]# yum -y install bind bind-chroot caching-nameserver
BIND設定ファイル所有グループ変更。
[root@centos ~]# chgrp named /var/named/chroot/etc/named.conf
色を付けた所を追加。
[root@localhost ~]# vi /var/named/chroot/etc/named.conf
//
// named.caching-nameserver.conf
//
// Provided by Red Hat caching-nameserver package to configure the
// ISC BIND named(8) DNS server as a caching only nameserver
// (as a localhost DNS resolver only).
//
// See /usr/share/doc/bind*/sample/ for example named configuration files.
//
// DO NOT EDIT THIS FILE - use system-config-bind or an editor
// to create named.conf - edits to this file will be lost on
// caching-nameserver package upgrade.
//
options {
# listen-on port 53 { 127.0.0.1; };
# listen-on-v6 port 53 { ::1; };
directory "/var/named";
dump-file "/var/named/data/cache_dump.db";
statistics-file "/var/named/data/named_stats.txt";

// Those options should be used carefully because they disable port

logging {
channel default_debug {
file "data/named.run";

view localhost_resolver {

ゾーンファイル作成。
[root@localhost ~]# vi /var/named/chroot/etc/named.localhost.com.zone
zone "localhost.com" {
type master;
file "localhost.com.db";
};
zone "0.168.192.in-addr.arpa" {
type master;
file "0.168.192.in-addr.arpa.db";
};
内部向け正引き用ファイル作成。
[root@localhost ~]# vi /var/named/chroot/var/named/localhost.com.db
$TTL 86400
@ IN SOA localhost.com. root.localhost.com.(
2004031901 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ) ; Minimum
IN NS localhost.com.
IN MX 10 localhost.com.
@ IN A 192.168.0.250
* IN A 192.168.0.250
内部向け逆引き用ファイル作成
[root@localhost ~]# vi /var/named/chroot/var/named/0.168.192.in-addr.arpa.db
$TTL 86400
@ IN SOA localhost.com. root.localhost.com.(
2004031901 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ) ; Minimum
IN NS localhost.com.
250 IN PTR localhost.com.
起動、自動起動設定
[root@localhost ~]# service named start named を起動中: [ OK ] [root@centos ~]# chkconfig named on [root@localhost ~]# chkconfig --list named named 0:off 1:off 2:on 3:on 4:on 5:on 6:off
nslookup などで、正引き、逆引きを確認。 複数のレコードを設定するときは、ゾーンファイルに zone{} を追加して、参照先のレコードを書いたファイルを作成。
