dnsmasq搭建dns局域网

dnsmasq搭建dns局域网

1.dns服务器一般都是安装bind服务器，如果是小型的域名解析需求，使用dnsmasq即可

2.安装dnsmasq软件

yum install dnsmasq -y

3.查看dnsmasq的主配置文件 /etc/dnsmasq.conf

[root@backup01 ~]# grep -Ev  "^#|^$" /etc/dnsmasq.conf

conf-dir=/etc/dnsmasq.d,.rpmnew,.rpmsave,.rpmorig

4.修改dnsmasq.conf如下参数:

查找/resolv-file参数修改如下

resolv-file=/etc/resolv.dnsmasq.conf #此参数指定上游dns服务器地址的参数

查找address参数 。vim命令模式下 查找/address,添加如下内容

#自定义某些域名及其子域名，都解析到某一个ip地址

address=/baidu.com/123.206.16.61

address=/taobao.com/123.206.16.61

#定义dnsmasq的监听地址的配置文件

listen-address=192.168.178.189

#定义一个本地域名配置文件，需要自定义的一些用户名解析记录

addn-hosts=/etc/dnsmasq.hosts

#开启记录dns查询的日志参数

log-queries

#启用如下蓝色参数，包含目录的语法，能够包含某一个文件下所有符合定义类型的配置文件

# Include another lot of configuration options.

#conf-file=/etc/dnsmasq.more.conf

conf-dir=/etc/dnsmasq.d

 

# Include all the files in a directory except those ending in .bak

conf-dir=/etc/dnsmasq.d,.bak

 

# Include all files in a directory which end in .conf

conf-dir=/etc/dnsmasq.d/,*.conf

5.自定义dnsmasq服务的配置文件如下

[root@backup01 ~]# grep -Ev "^#|^$" /etc/dnsmasq.conf

resolv-file=/etc/resolv.dnsmasq.conf

address=/baidu.com/123.206.16.61

address=/taobao.com/123.206.16.61

listen-address=192.168.178.189

addn-hosts=/etc/dnsmasq.hosts

log-queries

conf-dir=/etc/dnsmasq.d

conf-dir=/etc/dnsmasq.d,.bak

conf-dir=/etc/dnsmasq.d/,*.conf

conf-dir=/etc/dnsmasq.d,.rpmnew,.rpmsave,.rpmorig

6.内部解析地址关系，此两个文件需自己创建

[root@backup01 ~]# echo "123.206.16.61  yuchao668.com" > /etc/dnsmasq.hosts

[root@backup01 ~]# cat /etc/dnsmasq.hosts

123.206.16.61  yuchao668.com

7.添加上游dns服务器地址，当dnsmasq在本地找不到解析记录时去上游查找

[root@backup01 ~]# cat /etc/resolv.dnsmasq.conf

nameserver  119.29.29.29

nameserver  223.5.5.5

8.启动ndsmasq服务

[root@backup01 ~]# systemctl  start dnsmasq

[root@backup01 ~]# systemctl status dnsmasq

9.修改本地的dns客户端配置文件，指定自定义的dnsmasq服务器地址

[root@backup01 ~]# cat /etc/resolv.conf

# Generated by NetworkManager

#nameserver 119.29.29.29

nameserver  192.168.178.189

10.测试域名解析是否成功

> www.baidu.com 

Server:           192.168.178.189

Address: 192.168.178.189#53

 

Name:    www.baidu.com

Address: 123.206.16.61

> www.pythonav.cn

Server:           192.168.178.189

Address: 192.168.178.189#53

 

Non-authoritative answer:

Name:    www.pythonav.cn

Address: 123.206.16.61

结论：成功，
