安装所有bind套件以及其依赖的软件包

[root@dnsserver CentOS]# yum install bind*

查看安装了哪些
[root@dnsserver CentOS]# rpm -qa | grep bind
bind-chroot-9.3.6-4.P1.el5
bind-utils-9.3.6-4.P1.el5
bind-libs-9.3.6-4.P1.el5
ypbind-1.19-12.el5

kdebindings-3.5.4-6.el5
bind-libbind-devel-9.3.6-4.P1.el5
bind-devel-9.3.6-4.P1.el5
[root@dnsserver CentOS]#  yum install caching-nameserver-9.3.6-4.P1.el5.x86_64.rpm

由于chroot技术的使用，咱们BIND的配置文件name.conf还有区域文件都在/var/named/chroot/目录下

配置文件named.conf在/var/named/chroot/etc/下，而区域配置文件在/var/named/chroot/var/named/下

而在以前的默认路径/var/named下都是链接文件

ls -an /var/named/

drwxr-x---  6  0 25 4096 05-15 17:36 chroot

drwxrwx---  2 25 25 4096 02-23 06:35 data

lrwxrwxrwx  1  0 25   45 05-15 12:46 localdomain.zone -> /var/named/chroot//var/named/localdomain.zone

lrwxrwxrwx  1  0 25   43 05-15 12:46 localhost.zone -> /var/named/chroot//var/named/localhost.zone

lrwxrwxrwx  1  0 25   44 05-15 12:46 named.broadcast -> /var/named/chroot//var/named/named.broadcast

lrwxrwxrwx  1  0 25   37 05-15 12:46 named.ca -> /var/named/chroot//var/named/named.ca

lrwxrwxrwx  1  0 25   44 05-15 12:46 named.ip6.local -> /var/named/chroot//var/named/named.ip6.local

lrwxrwxrwx  1  0 25   40 05-15 12:46 named.local -> /var/named/chroot//var/named/named.local

lrwxrwxrwx  1  0 25   39 05-15 12:46 named.zero -> /var/named/chroot//var/named/named.zero

 

配置/var/named/chroot/etc/named.conf 主配置文件

1,cd /var/named/chroot/

2,cp etc/named.caching-nameserver.conf etc/named.conf

3,vim etc/named.conf

//改动地方红色标出

options {

        listen-on port 53 {any; };

        #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";

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

        // randomization

        // query-source    port 53;

        // query-source-v6 port 53;

        allow-query     { any; };

        allow-query-cache { localhost; };

};

logging {

        channel default_debug {

                file "data/named.run";

                severity dynamic;

        };

};

view localhost_resolver {

        match-clients      { any; };

        match-destinations { any; };

        recursion yes;

        include "/etc/named.rfc1912.zones";

};

 

修改etc/named.rfc1912.zones文件

vim etc/named.rfc1912.zones

zone "." IN {

        type hint;

        file "named.ca";

};

zone "localdomain" IN {

        type master;

        file "localdomain.zone";

        allow-update { none; };

};

zone "localhost" IN {

        type master;

        file "localhost.zone";

        type master;

        file "localhost.zone";

        allow-update { none; };

};

zone "0.0.127.in-addr.arpa" IN {

        type master;

        file "named.local";

        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 {

        type master;

        file "named.ip6.local";

        allow-update { none; };

};

zone "255.in-addr.arpa" IN {

        type master;

        file "named.broadcast";

        allow-update { none; };

};

        allow-update { none; };

};

 

zone "0.in-addr.arpa" IN {

        type master;

        file "named.zero";

        allow-update { none; };

};

zone "jason.net"{

        type master;

        file "jason.net.zone";

        allow-update {none;};

};

zone "16.168.192.in-addr.arpa" IN{

        type master;

        file "192.168.16.zone";

        allow-update {none;};

};

//我的局域网域名jason.net

新建/var/named/chroot/var/named/jason.net.zone 和192.168.16.zone

vim var/named/jason.net.zone

$TTL    86400

@               IN SOA  localhost root (

                                        42              ; serial (d. adams)

                                        3H              ; refresh

                                        15M             ; retry

                                        1W              ; expiry

                                        1D )            ; minimum

                IN NS           jason.net.

localhost       IN A            127.0.0.1

mail            IN A            192.168.16.176

master          IN A            192.168.16.173

vim var/named/192.168.16.zone

启动 service named start

 

我出现的错误

启动 named：
named配置错误：:
zone localdomain/IN: loaded serial 42
zone localhost/IN: loaded serial 42
zone 0.0.127.in-addr.arpa/IN: loaded serial 1997022700
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: loaded serial 1997022700

localhost_resolver/16.168.192.in-addr.arpa/IN: file not found

 

很明显找不着配置文件192.168.16.zone

 

原因在配置 etc/named.rfc1912.zones时

zone "16.168.192.in-addr.arpa" IN{

        type master;

        file "192.168.16.zone；";//多加了一个“；”

        allow-update {none;};

};
