Linux__dns服务器搭建

一配置主机名

vi /etc/sysconf/network

http://

二配置host文件

192.168.202.10 http:// node1

192.168.202.11 http:// node2

192.168.2.10 http:// node1-priv

192.168.2.11 http:// node2-priv

192.168.202.90 http:// node1-vip

192.168.202.91 http:// node2-vip

192.168.202.135 http:// cluster

192.168.202.136 http:// cluster

三安装需求包

yum install bind*

也可以

rpm–Uvh bind-utils-*

rpm –Uvhkdebindings-*

rpm–Uvh bind-*

rpm–Uvhypbind-*

rpm–Uvh bind-libs-*

rpm–Uvh bind-chroot-*

rpm–Uvh caching-nameserver-*

四启动

servernamed start (stop restart)

查看进程

rndc status (stop)

五配置named.conf文件

#cd /usr/share/doc/bind-9.3.6/sample/etc

#cp /usr/share/doc/bind-9.3.6/sample/etc/* /var/named/chroot/etc

#ln–s /var/named/chroot/etc/named.conf /etc/named.conf

#ln–s /var/named/chroot/etc/named.root.hints /etc/named.root.hints

#cd /usr/share/doc/bind-9.3.6/sample/var/

#cp–r /usr/share/doc/bind-9.3.6/sample/var/* /var/named/chroot/var/

vi/var/named/chroot/etc/named.conf

view "localhost_resolver"

{

/* This view sets up named to be a localhost resolver ( caching only nameserver ).

* If all you want is a caching-only nameserver, then you need only define this view:

*/

match-clients { localhost; };

match-destinations { localhost; };

recursion yes;

# all views must contain the root hints zone:

include "/etc/named.root.hints";

/* these are zones that contain definitions for all the localhost

* names and addresses, as recommended in RFC1912 - these names should * ONLY be served to localhost clients:

*/

zone "http://" {

type master;

file "http://";

};

zone "202.168.192.in-addr.arpa" IN {

type master;

file "named.192.168.202";

};

include "/etc/rndc.key"; (这个目录里面的密匙后面的哪儿可以用到)

};

view "internal"

{

/* This view will contain zones you want to serve only to "internal" clients

that connect via your directly attached LAN interfaces - "localnets" .

*/

match-clients { localnets; };

match-destinations { localnets; };

recursion yes;

// all views must contain the root hints zone:

include "/etc/named.root.hints";

// include "named.rfc1912.zones";

// you should not serve your rfc1912 names to non-localhost clients.

// These are your "authoritative" internal zones, and would probably

// also be included in the "localhost_resolver" view above :

zone "http://" {

type master;

file "http://";

};

zone "202.168.192.in-addr.arpa" IN {

type master;

file "named.192.168.202";

};

zone "my.slave.internal.zone" {

type slave;

file "slaves/my.slave.internal.zone.db";

masters { /* put master nameserver IPs here */ 127.0.0.1; } ;

// put slave zones in the slaves/ directory so named can update them };

zone "my.ddns.internal.zone" {

type master;

allow-update { key ddns_key; };

file "slaves/my.ddns.internal.zone.db";

// put dynamically updateable zones in the slaves/ directory so named can update them

};

};

keyddns_key

{

algorithm hmac-md5;

secret "MNE1hiqdU52EOUbnxKfobZUG5y2S5BAqbvdHqHEygTCqEKtsbUWc2Yu2Key9"; };

view "external"

{

/* This view will contain zones you want to serve only to "external" clients

* that have addresses that are not on your directly attached LAN interface subnets:

*/

match-clients { any; };

match-destinations { any; };

recursion no;

// you'd probably want to deny recursion to external clients, so you don't

// end up providing free DNS service to all takers

allow-query-cache { none; };

// Disable lookups for any cached data and root hints

// all views must contain the root hints zone:

include "/etc/named.root.hints";

// These are your "authoritative" external zones, and would probably

Linux__dns服务器搭建

// contain entries for just your web and mail servers:

zone "my.external.zone" {

type master;

file "my.external.zone.db";

};

};

下面配置指定的两个文件：

#cd /var/named/chroot/var/named

http://

[root@node1 named]# cat http://

$TTL 300

@ SOA http://. http://. (

2003053013 ;serial (d. adams) 3600 ;refresh 900 ;retry 1209600 ;expiry 3600 ;minimum )

@ IN NS http://.

node1 IN A 192.168.202.10

cluster IN A 192.168.202.135

在创建配置另外一个：

vi name.192.168.202

[root@node1 named]# cat named.192.168.202

$TTL 300

@ SOA http://. http://. (

2003053013 ;serial (d. adams) 3600 ;refresh 900 ;retry 1209600 ;expiry 3600 ;minimum )

@ IN NS http://.

10 IN PTR http://.

135 IN PTR http://.

注：可以把这个文件再复制一份到/var/named/ 下面

六配置/etc/resolv.conf

domain http://

search http://

nameserver 192.168.202.10

host http://

host 192.168.202.10

七重启named 服务

#server named restart # rndc reload

八用nslookup测试

[root@node1 named]# nslookup

> 192.168.202.10

Server: 192.168.202.10

Address: 192.168.202.10#53

10.202.168.192.in-addr.arpa name = http://. >my

Server: 192.168.202.10

Address: 192.168.202.10#53

** server can't find my: SERVFAIL

> http://
