RHEL5下DNS配置

[align=center]RedHat EL5 DNS 配置[/align]
[align=left]在[b]RedHat EL5下配置DNS服务：[/b][/align]
[align=left]一、安装 bind（与 [b]RedHat EL4安装方法一样）[/b][/align]
[align=left]二、配置[/align]
[align=left] 1、在/etc没有了named.conf 文件，而是多了以下两个文件：[/align]
//
// 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";
memstatistics-file "/var/named/data/named_mem_stats.txt";
query-source port 53;
query-source-v6 port 53;
allow-query { localhost; };
};
logging {

};
};

recursion yes;
include "/etc/named.rfc1912.zones"; //调用named.rfc1912.zones
};
// named.rfc1912.zones: //添加解析区域
//
// Provided by Red Hat caching-nameserver package
//
// ISC BIND named zone configuration for zones recommended by
// RFC 1912 section 4.1 : localhost TLDs and address zones
//
// See /usr/share/doc/bind*/sample/ for example named configuration files.
//

};

file "localdomain.zone";
allow-update { none; };
};

allow-update { none; };
};

allow-update { none; };
};
zone "0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa" IN {

allow-update { none; };
};

zone "benet.com" IN {
type master;
file "named.benet";
allow-update { none; };
};
zone "0.168.192.in-addr.arpa" IN {
type master;
file "named.192";
allow-update { none; };
};

2、在/var/named/chroot/var/named 下建立解析库文件
三、注意事项
在建立解析库文件时，其文件所属用户和组均为root，在启动named时，日志提示“权限不够。。。”，后将两个解析库文件组改为named ，问题解决。
