(2)　設定

• （ⅰ）ブートファイルの設定

# vi /etc/sysconfig/named
ROOTDIR=/var/named/chroot　（chrootの確認）
# cp /usr/share/doc/bind-9.3.4/sample/etc/named.conf /var/named/chroot/etc/
# chown root:named /var/named/chroot/etc/named.conf
　（権限を変更しないと作動しない）
# chmod 640 /var/named/chroot/etc/named.conf

options
{
 query-source    port 53;
 query-source-v6 port 53;
 directory "/var/named";
 dump-file          "data/cache_dump.db";
 statistics-file    "data/named_stats.txt";
 memstatistics-file "data/named_mem_stats.txt";
};
logging
{
 channel default_debug {
 file "data/named.run";
 severity dynamic;
 };
};
view "internal"
{
 match-clients           { localnets; };
 match-destinations      { localnets; };
 recursion yes;
 include "/etc/named.rfc1912.zones";
 zone "0gino.jp" {
   type master;
   file "0gino.jp.zone";
 };
 zone "1.168.192.in-addr.arpa" {
   type master;
   file "1.168.192.in-addr.arpa.zone";
 };
};

view    "external"
{
 recursion no;
 allow-query { none; };
 zone "." {
   type hint;
   file "/dev/null";
   };
 zone "0gino.jp" {
   type master;
   file "0gino.jp.zone";
   allow-query { any; };
 };
 zone "1.168.192.in-addr.arpa" {
   type master;
   file "1.168.192.in-addr.arpa.zone";
   allow-query { any; };
 };
};

• （ⅱ）正引きゾーンファイルの設定

# vi /var/named/chroot/var/named/0gino.jp.zone

$TTL    86400
@ IN SOA ns.0gino.jp. root.0gino.jp. (
  2008080903      ; Serial
  10800           ; Refresh after 3 hours
  3600            ; Retry after 1 hours
  604800          ; Expire after 1 week
