DNSサーバーを構築します。
そのためのソフトがbind（Berkeley Internet Name Domain）です。
詳しい内容の解説はインターネットで検索してください。
インストールするのは、bind　bind-chroot　caching-nameserverなのですが、yum install bind　bind-chroot　caching-nameserverと併記してうまく行かなかったような経験があるので、最近は１個づつインストール事が多くなりました。
ここでも、そのようにしています。

次にbind-chrootをインストールします。
bind-chrootを導入するとbindの設定ファイル類が階層を保ったまま移動しますので、bindがhackされた場合でもapacheに影響を与えません。
つまり、安全性が高まります。

caching-nameserverもインストールします。
caching-nameserverは、１度問い合わせを行った内容を一定期間ローカルに記憶しておきます。
検索が早くなるのとnameserverの負荷を軽減します。

これからの設定ファイルの作成が結構面倒です。
手入力をしていたのでは、時間が掛かるだけでなく入力ミスも発生し易いため、コピペすべきでしょう。
色々なサイトが解説を行っておりますが、記載する内容はほとんど同一です。
ファイル名を自分のサーバー用に変更するだけですから、作業はかなり楽になります。
他所（よそ）のサイトの内容をそのまま載せる訳にはいかないでしょうから、リンクだけしておきます。
Fedora で自宅サーバー構築さんの場合です。
ここの解説通りで特に問題無くインストールできました。
私のように動作をする事が確認できれば良いのであれば、このサイトの解説で十分です。

他を見るなら初めての自宅サーバー構築と言うサイトもあります。
深い所まで知ろうとすると、インターネット上には詳しい解説がいくらでもあります。

【2009年8月追記】
上記サイトの現在の設定の内容が玄箱HG＋Fedora6の以前の内容と大幅に異なっておりました。
以前の設定内容は以下の通りです。

以前のファイルをそのままコピー（Serialは増やす）して、BINDを起動しましたらエラー無く終了しました。
但し、正常に動作しているかの確認は十分にしておりません、
