1、系统环境说明

[[email protected] etc]# cat /etc/redhat-release

CentOS Linux release7.3.1611(Core)

防火墙和Selinux关闭

[[email protected]-server etc]# systemctl status firewalld.service

● firewalld.service- firewalld -dynamic firewall daemon

Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)

Active: inactive (dead)

Docs:man:firewalld(1)

Oct11 09:46:22 localhost.localdomain systemd[1]: Starting firewalld -dynamic firewall daemon...

Oct11 09:46:23 localhost.localdomain systemd[1]: Started firewalld -dynamic firewall daemon.

Oct11 09:48:35 localhost.localdomain systemd[1]: Stopping firewalld -dynamic firewall daemon...

Oct11 09:48:35 localhost.localdomain systemd[1]: Stopped firewalld -dynamic firewall daemon.

[[email protected]-server etc]# getenforce

Permissive

[[email protected]-server etc]# hostname -I10.0.3.57

2、安装bind

[[email protected] ~]# yum install bind* -ql bind/etc/named.conf # 主配置文件/etc/named.rfc1912.zones # 区域解析库文件/var/log/named.log #日志文件/var/named #服务根目录

3、修改配置文件

[[email protected] ~]# cp /etc/named.conf{,.bak}

[[email protected]-server ~]# vim /etc/named.conf

#删除IPv6地址，修改监听地址options { listen-on port 53 { 10.0.3.57; };

.... allow-query { localhost;any; }; //允许DNS查询客户端

...

}

4、启动bind服务

named.conf

#启动bind服务

[[email protected]-server ~]# systemctl start named

[[email protected]-server ~]# netstat -lntup|grep 53tcp0 0 10.0.3.57:53 0.0.0.0:* LISTEN 8053/named

tcp0 0 127.0.0.1:953 0.0.0.0:* LISTEN 8053/named

tcp60 0 ::1:953 :::* LISTEN 8053/named

udp0 0 10.0.3.57:53 0.0.0.0:* 8053/named

#测试DNS服务器 dig @表示指定NDS服务器

[[email protected]-server ~]# dig baidu.com @10.0.3.57;<<>> DiG 9.9.4-RedHat-9.9.4-61.el7_5.1 <<>> baidu.com @10.0.3.57;; global options:+cmd

5、搭建内网DNS服务器

让当前的DNS解析qipai.com域名

/etc/named.conf

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

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

主配置文件中指定了/etc/named.rfc1912.zones文件

01.将域名 IP 关系存储在DNS上，在/etc/named.rfc1912.zones 文件中进行添加

[[email protected]~]# vim /etc/named.rfc1912.zones

zone"qipai.com"IN { # qipai.com是域名

type master; # 表示权威DNS，即第一个file "qipai.com.zone"; # 域数据库，默认位于/var/named/下面，只需告知文件名qipai.com.zone是库文件名

};

02.以/var/named目录下的named.localhost为模板，创建nmtui.com.zone文件，创建区域数据库

[[email protected] ~]# cd /var/named/

[[email protected] named]#cp -av named.localhost qipai.com.zone‘named.localhost‘ -> ‘nmtui.com.zone‘ ## 注意cp -a 保持原有属性

03.解析区域数据库格式，存放域名与IP的对应关系[[email protected] named]# catqipai.com.zone$TTL 1D

@ IN SOA @ qipai.top. (30; serial 1M ; refresh 1M ; retry 1M ; expire 3M ) ; minimum NS @ admin A10.0.3.10gm2.admin A10.0.3.10@ A10.0.3.10

6、检查配置文件，重启bind服务

[[email protected] named]# named-checkzone qipai.com /var/named/qipai.com.zone

zone qipai.com/IN: loaded serial 30

7、测试DNS是否生效

Linux测试

[[email protected] named]# dig qipai.com @10.0.3.57;<<>> DiG 9.9.4-RedHat-9.9.4-61.el7_5.1 <<>> qipai.com @10.0.3.57;; global options:+cmd

;; Got answer:

;;->>HEADER<

; EDNS: version:0, flags:; udp: 4096;; QUESTION SECTION:

;qipai.com. IN A

;; ANSWER SECTION:

qipai.com.86400 IN A 10.0.3.10;; AUTHORITY SECTION:

qipai.com.86400IN NS qipai.com.

;; Querytime: 1msec

;; SERVER:10.0.3.57#53(10.0.3.57)

;; WHEN: Thu Oct11 18:26:21 CST 2018;; MSG SIZE rcvd:68

修改网卡配置文件(/etc/sysconfig/network-scripts/ifcfg-eth0)或/etc/resolv.conf 指定DNS解析

Windows测试，指定DNS服务器
