centos配置dns服务器

1、配置yum源

http://blog.csdn.net/kadwf123/article/details/78231694

2、修改服务器的主机名：

[root@MYDNS ~]# vi /etc/sysconfig/network

NETWORKING=yes
HOSTNAME=MYDNS

改成MYDNS

3、使用yum源安装dns服务包

[root@MYDNS etc]# yum -y install bind-libs bind bind-utils

Complete!
[root@MYDNS etc]# 

4、配置dns主配置文件

原文件不需要备份掉：

[root@MYDNS etc]# mv named.conf named.conf_bak

[root@MYDNS etc]# vi named.conf

options {

        directory "/var/named";     // Base directory for named
        allow-transfer {"none";};   // Slave serves that can pull zone transfer. Ban everyone by default

        };

zone "." IN {
        type hint;
        file "named.ca";
};

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

zone "0.168.192.IN-ADDR.ARPA." IN { // Reverse zone.
        type master;
        notify no;
        file "192.168.0.db";
};

zone "taryartar.com." IN {
        type master;
        notify no;
        file "taryartar.com.db";
};

写入如下内容，保存。

5、进入上面配置的主目录中：

[root@MYDNS etc]# cd /var/named

6、创建正向解析文件：

[root@MYDNS named]# vi taryartar.com.db

$TTL 1H         ; Time to live
$ORIGIN  taryartar.com.
@       IN      SOA     mydns  root.taryartar.com.  (
                        2013011201      ; serial (todays date + todays serial #)
                        3H              ; refresh 3 hours
                        1H              ; retry 1 hour
                        1W              ; expire 1 week
                        1D )            ; minimum 24 hour

@       IN              NS  mydns
;
        IN              A 192.168.0.88
mydns           IN A    192.168.0.88
rac1            IN A    192.168.0.51
rac2            IN A    192.168.0.52
rac3            IN A    192.168.0.53
rac4            IN A    192.168.0.54
rac1-vip        IN A    192.168.0.55
rac2-vip        IN A    192.168.0.56
rac3-vip        IN A    192.168.0.57

rac1-priv2      IN A    10.0.10.2
rac2-priv1      IN A    10.0.10.3
rac2-priv2      IN A    10.0.10.4
rac3-priv1      IN A    10.0.10.5
rac3-priv2      IN A    10.0.10.6
rac4-priv1      IN A    10.0.10.7
rac4-priv2      IN A    10.0.10.8
;

7、创建反向解析文件：

[root@MYDNS named]# vi 192.168.0.db

$TTL 1H
@       IN      SOA     mydns  root.taryartar.com.  (
                        2013011201      ; serial (todays date + todays serial #)
                        3H              ; refresh 3 hours
                        1H              ; retry 1 hour
                        1W              ; expire 1 week
                        1D )            ; minimum 24 hour
;
                 NS       mydns.taryartar.com.
88      IN      PTR       mydns.taryartar.com.
89      IN      PTR       gnsvip.taryartar.com. ; reverse mapping for GNS
51      IN PTR  rac1.taryartar.com.
52      IN PTR  rac2.taryartar.com.
53      IN PTR  rac3.taryartar.com.
54      IN PTR  rac4.taryartar.com.
55      IN PTR  rac1-vip.taryartar.com.
56      IN PTR  rac2-vip.taryartar.com.
57      IN PTR  rac3-vip.taryartar.com.
58      IN PTR  rac4-vip.taryartar.com.
61      IN PTR  myscan.taryartar.com.
62      IN PTR  myscan.taryartar.com.
63      IN PTR  myscan.taryartar.com.
1       IN PTR  rac1-priv1.taryartar.com.
2       IN PTR  rac1-priv2.taryartar.com.
3       IN PTR  rac2-priv1.taryartar.com.
4       IN PTR  rac2-priv2.taryartar.com.
5       IN PTR  rac3-priv1.taryartar.com.
6       IN PTR  rac3-priv2.taryartar.com.
7       IN PTR  rac4-priv1.taryartar.com.
8       IN PTR  rac4-priv2.taryartar.com.

8、启动dns

[root@MYDNS named]# service named start
Generating /etc/rndc.key:[确定]
启动 named：[确定]
[root@MYDNS named]# ps -ef|grep name
named     2492     1  0 11:22 ?        00:00:00 /usr/sbin/named -u named
root      2500  2015  0 11:22 pts/1    00:00:00 grep name

9、添加开机自启动：

[root@MYDNS named]# chkconfig named on
[root@MYDNS named]# chkconfig --list |grep name
named           0:关闭  1:关闭  2:启用  3:启用  4:启用  5:启用  6:关闭
[root@MYDNS named]#

10、配置客户端使用dns服务器

/etc/resolv.conf添加如下内容：

[root@MYDNS etc]# vi /etc/resolv.conf

options attempts: 2 
options timeout: 1
search taryartar.com
nameserver 192.168.0.88

11、测试正向解析：

[root@MYDNS etc]# nslookup rac1
Server:         192.168.0.88
Address:        192.168.0.88#53

Name:   rac1.taryartar.com
Address: 192.168.0.51

[root@MYDNS etc]# host rac1
rac1.taryartar.com has address 192.168.0.51
[root@MYDNS etc]# host rac2
rac2.taryartar.com has address 192.168.0.52
[root@MYDNS etc]# host rac1.taryartar.com
rac1.taryartar.com has address 192.168.0.51

12、测试反向解析：

[root@MYDNS etc]# nslookup 192.168.0.52
Server:         192.168.0.88
Address:        192.168.0.88#53

52.0.168.192.in-addr.arpa       name = rac2.taryartar.com.

13、都没问题，ok
