**Linux** **配置****DNS**

**一、正向解析与反向解析**

**实现通过****DNS****配置可以访问正反向解析百度和贴吧以及文库和知道****IP****地址和域名**

**正向解析**

<table> 
 <tbody> 
 <tr> 
 <td style="border-color:#bdd6ee;vertical-align:top;width:138.25pt;"> 主机名 </td> 
 <td style="vertical-align:top;width:138.25pt;"> 正向解析 </td>

**反向解析**

**二、****Linux****操纵**

**1.****查看本机的****IP****地址为****192.168.31.133**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTk4NzAxNg_size_16_color_FFFFFF_t_70][]

**2.****永久地修改主机名字**

**hostnamectl set-hostname mtc;**

**3.****查看****bind**

**yum list | grep bind;**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTk4NzAxNg_size_16_color_FFFFFF_t_70 1][]

**4.****安装****DNS****服务器**

**    DNS****服务安装软件名字为****bind****，还有其他相关的软件包，安装****DNS****服务跟安装****samba****、****dhcp****服务步骤相同，首先检查系统中是否已安装****bind****包**

**yum -y install bind;**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTk4NzAxNg_size_16_color_FFFFFF_t_70 2][]

**5.****修改** **/etc/named.conf****文件中****listen-on port 53 \{ 127.0.0.1; \}****为****listen-on port 53 \{ 127.0.0.1;any;\}**

**修改** **allow-query     \{ localhost; \}****为****allow-query     \{ localhost;any; \}**

**代码为：**

**sed -i 's/listen-on port 53 \{ 127.0.0.1; \};/listen-on port 53 \{ 127.0.0.1;any;\};/'   /etc/named.conf;**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTk4NzAxNg_size_16_color_FFFFFF_t_70 3][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTk4NzAxNg_size_16_color_FFFFFF_t_70 4][]

**cd /etc**

**cat named.rfc1912.zones**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTk4NzAxNg_size_16_color_FFFFFF_t_70 5][]

**6.****添加正向的域和反向的域**

**echo '''**

**//****正向的域**

**zone "centos-dns.cc" IN \{**

**       type master;**

**       file "centos-dns.cc.zone";**

**       allow-update \{ none; \};**

**\};**

**//****反向的域****:****注意****IP****地址反过来写，最后一位不固定**

**zone "21.220.138.in-addr.arpa" IN \{**

**       type master;**

**       file "138.220.21.zone";**

**       allow-update \{ none; \};**

**\};**

**''' >>/etc/named.rfc1912.zones;**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTk4NzAxNg_size_16_color_FFFFFF_t_70 6][]

**7.****查看添加后的文件的内容**

**cat named.rfc1912.zones**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTk4NzAxNg_size_16_color_FFFFFF_t_70 7][]

**8.****在****/var/named/****下创建****centos-dns.cc.zone**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTk4NzAxNg_size_16_color_FFFFFF_t_70 8][]

**9.****在****var/named****下创建****138.220.21.zone**

**echo '''**

**$TTL 1D**

**@       IN SOA  centos-dns.cc. rname.invalid. (**

**                                        0       ; serial**

**                                        1D      ; refresh**

**                                        1H      ; retry**

**                                        1W      ; expire**

**                                        3H )    ; minimum**

**@         NS      mtc.centos-dns.cc.**

**11        PTR     www.centos-dns.cc.**

**22        PTR     zhidao.centos-dns.cc.**

**chgrp named  /var/named/centos-dns.cc.zone;**

**named-checkconf /etc/named.conf;**

**cd /var/named/;**

**named-checkzone centos-dns.cc.zone  centos-dns.cc.zone;**

**echo '''**

**nameserver 192.168.31.133**

**nameserver 8.8.8.8**

**'''>/etc/resolv.conf;**

![20191226171321408.png][]

**10.****开启****named**

**systemctl start named;**

**systemctl status named;**

**关闭防火墙**

**systemctl stop firewalld.service;**

**firewall-cmd --state;**

**setenforce 0;**

**getenforce;**

**安装****bind-utils**

**yum -y install bind-utils**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTk4NzAxNg_size_16_color_FFFFFF_t_70 12][]

**三、验证正反向域名解析是否成功**

**nslookup wenku.centos-dns.cc;**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTk4NzAxNg_size_16_color_FFFFFF_t_70 13][]

**nslookup 138.220.21.22;**

**host  tieba.centos-dns.cc**

**nslookup 138.220.21.22;**

**host  tieba.centos-dns.cc**

**host 138.220.21.33**

**dig @192.168.31.133 tieba.centos-dns.cc**

**dig -x 138.220.21.22 @192.168.31.133**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTk4NzAxNg_size_16_color_FFFFFF_t_70 15][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTk4NzAxNg_size_16_color_FFFFFF_t_70 16][]
