CentOS 前端之家
前端之家收集整理的这篇文章主要介绍了centos配置dns服务器，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。

1、配置yum源

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

2、修改服务器的主机名：

  1. [root@MYDNS ~]# vi /etc/sysconfig/network
  1. NETWORKING=yes
  2. HOSTNAME=MYDNS
改成MYDNS

3、使用yum源安装dns服务包

  1. [root@MYDNS etc]# yum -y install bind-libs bind bind-utils
  2. Loaded plugins: fastestmirror,security
  3. Loading mirror speeds from cached hostfile
  4. Setting up Install Process

  72.  
  73. Complete!
  74. [root@MYDNS etc]#

4、配置dns主配置文件

原文件不需要备份掉：

  1. [root@MYDNS etc]# mv named.conf named.conf_bak
  1. [root@MYDNS etc]# vi named.conf
  2.  
  3. options {
  4.  
  5.         directory "/var/named";     // Base directory for named
  6.         allow-transfer {"none";};   // Slave serves that can pull zone transfer. Ban everyone by default
  7.  
  8.         };
  9.  
  10. zone "." IN {
  11.         type hint;
  12.         file "named.ca";
  13. };
  14.  
  15. include "/etc/named.rfc1912.zones";
  16.  
  17. zone "0.168.192.IN-ADDR.ARPA." IN { // Reverse zone.
  18.         type master;
  19.         notify no;
  20.         file "192.168.0.db";
  21. };
  22.  
  23. zone "taryartar.com." IN {
  24.         type master;
  25.         notify no;
  26.         file "taryartar.com.db";
  27. };

写入如下内容，保存。

5、进入上面配置的主目录中：

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

6、创建正向解析文件：

  1. [root@MYDNS named]# vi taryartar.com.db
  2.  
  3. $TTL 1H         ; Time to live
  4. $ORIGIN  taryartar.com.
  5. @       IN      SOA     mydns  root.taryartar.com.  (
  6.                         2013011201      ; serial (todays date + todays serial #)
  7.                         3H              ; refresh 3 hours
  8.                         1H              ; retry 1 hour
  9.                         1W              ; expire 1 week
  10.                         1D )            ; minimum 24 hour
  11.  
  12. @       IN              NS  mydns
  13. ;
  14.         IN              A 192.168.0.88
  15. mydns           IN A    192.168.0.88
  16. rac1            IN A    192.168.0.51
  17. rac2            IN A    192.168.0.52
  18. rac3            IN A    192.168.0.53
  19. rac4            IN A    192.168.0.54
  20. rac1-vip        IN A    192.168.0.55
  21. rac2-vip        IN A    192.168.0.56

  25. myscan          IN A    192.168.0.62
  26. myscan          IN A    192.168.0.63
  27. rac1-priv1      IN A    10.0.10.1
  28. rac1-priv2      IN A    10.0.10.2
  29. rac2-priv1      IN A    10.0.10.3
  30. rac2-priv2      IN A    10.0.10.4

  34. rac4-priv2      IN A    10.0.10.8
  35. ;

7、创建反向解析文件： 
  1. [root@MYDNS named]# vi 192.168.0.db
  2.  
  3. $TTL 1H
  4. @       IN      SOA     mydns  root.taryartar.com.  (
  5.                         2013011201      ; serial (todays date + todays serial #)
  6.                         3H              ; refresh 3 hours
  7.                         1H              ; retry 1 hour
  8.                         1W              ; expire 1 week
  9.                         1D )            ; minimum 24 hour
  10. ;
  11.                  NS       mydns.taryartar.com.
  12. 88      IN      PTR       mydns.taryartar.com.
  13. 89      IN      PTR       gnsvip.taryartar.com. ; reverse mapping for GNS
  14. 51      IN PTR  rac1.taryartar.com.
  15. 52      IN PTR  rac2.taryartar.com.
  16. 53      IN PTR  rac3.taryartar.com.
  17. 54      IN PTR  rac4.taryartar.com.
  18. 55      IN PTR  rac1-vip.taryartar.com.
  19. 56      IN PTR  rac2-vip.taryartar.com.
  20. 57      IN PTR  rac3-vip.taryartar.com.
  21. 58      IN PTR  rac4-vip.taryartar.com.
  22. 61      IN PTR  myscan.taryartar.com.
  23. 62      IN PTR  myscan.taryartar.com.
  24. 63      IN PTR  myscan.taryartar.com.
  25. 1       IN PTR  rac1-priv1.taryartar.com.
  26. 2       IN PTR  rac1-priv2.taryartar.com.
  27. 3       IN PTR  rac2-priv1.taryartar.com.
  28. 4       IN PTR  rac2-priv2.taryartar.com.
  29. 5       IN PTR  rac3-priv1.taryartar.com.
  30. 6       IN PTR  rac3-priv2.taryartar.com.
  31. 7       IN PTR  rac4-priv1.taryartar.com.
  32. 8       IN PTR  rac4-priv2.taryartar.com.

8、启动dns 
  1. [root@MYDNS named]# service named start
  2. Generating /etc/rndc.key:[确定]
  3. 启动 named：[确定]
  4. [root@MYDNS named]# ps -ef|grep name
  5. named     2492     1  0 11:22 ?        00:00:00 /usr/sbin/named -u named
  6. root      2500  2015  0 11:22 pts/1    00:00:00 grep name
9、添加开机自启动： 
  1. [root@MYDNS named]# chkconfig named on
  2. [root@MYDNS named]# chkconfig --list |grep name
  3. named           0:关闭  1:关闭  2:启用  3:启用  4:启用  5:启用  6:关闭
  4. [root@MYDNS named]#

10、配置客户端使用dns服务器

/etc/resolv.conf添加如下内容：

  1. [root@MYDNS etc]# vi /etc/resolv.conf
  2.  
  3. options attempts: 2 
  4. options timeout: 1
  5. search taryartar.com
  6. nameserver 192.168.0.88
11、测试正向解析： 
  1. [root@MYDNS etc]# nslookup rac1
  2. Server:         192.168.0.88
  3. Address:        192.168.0.88#53
  4.  
  5. Name:   rac1.taryartar.com
  6. Address: 192.168.0.51
  7.  
  8. [root@MYDNS etc]# host rac1
  9. rac1.taryartar.com has address 192.168.0.51
  10. [root@MYDNS etc]# host rac2
  11. rac2.taryartar.com has address 192.168.0.52
  12. [root@MYDNS etc]# host rac1.taryartar.com
  13. rac1.taryartar.com has address 192.168.0.51

12、测试反向解析： 
  1. [root@MYDNS etc]# nslookup 192.168.0.52
  2. Server:         192.168.0.88
  3. Address:        192.168.0.88#53
  4.  
  5. 52.0.168.192.in-addr.arpa       name = rac2.taryartar.com.
