Linux DNS Server 配置

1， 首先查看是否安装以下的软件包
bind-libs- 9.3.3-10.el5
bind-devel-9.3.3-10.el5
bind-9.3.3-10.el5
bind-chroot-9.3.3-10.el5
bind-utils-9.3.3-10.el5
caching-nameserver-9.3.3-10.el5
2，对配置文件配置
vi named.caching-nameserver.conf
如：
options {
# listen-on port 53 { 10.6.0.156; }; 这个是本机的IP。
# listen-on-v6 port 53 { ::1; };
listen-on-v6 port 53 {any;}; any 和：：1的区别是什么？
listen-on port 53 {any;};
directory "/var/named"; 定义dns mapping 文件的目录
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;}
allow-query { any; };

dnssec-enable yes;
dnssec-validation yes;
dnssec-lookaside auto;

/* Path to ISC DLV key */
bindkeys-file "/etc/named.iscdlv.key";

managed-keys-directory "/var/named/dynamic";
};

};
logging {
channel default_debug {
file "data/named.run";
severity dynamic;
};
};
view localhost_resolver {
match-clients { 10.6.0.156t; };
match-destinations { 10.6.0.156; };
recursion yes;
include "/etc/named.rfc1912.zones";
}; #也可以把有关zone的配置放在/etc/named.caching-nameserver.conf目录下。

3. vi /etc/named.rfc1912.zones
如下：
zone "test.com" IN {
type master;
file "test.com.zero";
allow-update { none; };
};

zone "0.6.10.in-addr.arpa" IN {
type master;
file "10.6.0.ptr";
allow-update { none; };
};
#IN 可以省略。zone内容不可以重复。
4，再在/var/named/目录中创建相应的正反解析文件
正向解析：
[root@test ~]# cat /var/named/test.com.zone
$TTL 30
@ IN SOA @ root (
42 ; serial (d. adams)
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum
IN NS @
www IN A 10.6.0.156
polo IN A 10.6.0.156
test IN A 10.6.0.156
smtp IN MX 10 10.6.0.156
mail IN CNAME smtp.test.com

反向解析：
[root@test ~]# cat /var/named/10.6.0.ptr
$TTL 86400
@ IN SOA @ root (
42 ; serial (d. adams)
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum
IN NS @
156 IN PTR www.test.com.
156 IN PTR polo.test.com.
156 IN PTR ftp.test.com.
156 IN PTR mail.test.com.

注意：域名后面都要以“.”结束。
把两个正反解析文件CP到/var/named/chroot/var/named目录下，注意文件属于组，以及权限。
/etc/resolv.conf 添加nameserver 10.6.0156
