  • 筆記

1、準備

例：兩台192.168.219.146(主), 192.168.219.147(從), 域名www.panyangduola.com

主、從DNS伺服器均需要安裝bind、bind-chroot、bind-utils

yum -y install bind bind-utils bind-chroot

如果防火牆開啟，配置防火牆，添加服務(防火牆已禁用則忽略)

firewall-cmd --permanent --add-service=dns  firewall-cmd --reload

2、主DNS伺服器(192.168.219.146)配置

編輯配置文件

vim /etc/named.conf

找到其中兩行

  1. listen-on port 53 { 127.0.0.1; };

  2. allow-query { localhost; };

    修改為

  3. listen-on port 53 { any; };

  4. allow-query { any; };

2-1、配置正向解析

編輯文件/etc/named.rfc1912.zones，在末尾添加需要解析的域

vim /etc/named.rfc1912.zones
zone "panyangduola.com" IN {        type master;        file "data/panyangduola.com.zone";  };

創建panyangduola.com.zone解析域

vim /var/named/data/panyangduola.com.zone
$TTL 3600  $ORIGIN panyangduola.com.  @       IN      SOA   panyangduola.com. admin.panyangduola.com. (          2018042101          1D          1H          1W          3H  )  @       IN      NS      ns1.panyangduola.com.  @       IN      NS      ns2.panyangduola.com.  ns1     IN      A       192.168.219.146  ns2     IN      A       192.168.219.147  www     IN      A       192.168.219.146  web     IN      CNAME   www

2-2、配置反向解析

編輯文件/etc/named.rfc1912.zones，在末尾添加需要解析的域

vim /etc/named.rfc1912.zones
zone "219.168.192.in-addr.arpa" IN {            type master;            file "data/219.168.192.zone";  };

創建219.168.192.zone解析域

vim /var/named/data/219.168.192.zone
$TTL 3600  $ORIGIN  219.168.192.in-addr.arpa.  @       IN      SOA  panyangduola.com. admin.panyangduola.com. (          2018042101          1D          1H          1W          3H  )  @       IN      NS      ns1.panyangduola.com.  @       IN      NS      ns2.panyangduola.com.  146      IN      PTR     ns1.panyangduola.com.  147      IN      PTR     ns2.panyangduola.com.  146      IN      PTR     www.panyangduola.com.

2-3、對DNS配置文件進行一下語法檢查：

cd /etc  named-checkconf named.conf  named-checkconf named.rfc1912.zones  cd /var/named/data  named-checkzone panyangduola.com panyangduola.com.zone  named-checkzone 219.168.192.in-addr.arpa 219.168.192.zone

2-4、編輯/etc/resolv.conf，添加

vim /etc/resolv.conf
search localdomain  nameserver 192.168.219.146

2-5、如果2-3步驟沒有錯誤發生的話，啟動named服務

重啟named

systemctl restart named

查看狀態

systemctl status named

2-6、檢查主DNS伺服器解析是否成功

ping命令驗證

ping -c 4 www.panyangduola.com

nslookup命令驗證

nslookup  >www.panyangduola.com
nslookup  >192.168.219.146

3、從DNS伺服器(192.168.219.147)配置

編輯named.conf文件

vim /etc/named.conf

找到其中兩行　　

  1. listen-on port 53 { 127.0.0.1; }; 　　
  2. allow-query { localhost; };

修改為

  1. listen-on port 53 { any; };
  2. allow-query { any; };

3-1、修改主DNS伺服器(192.168.219.146)的配置/etc/named.rfc1912.zones

vim /etc/named.rfc1912.zones
zone "panyangduola.com" IN {        type master;        file "data/panyangduola.com.zone";        allow-transfer {192.168.219.147;};        notify yes;        also-notify {192.168.219.147;};  };  zone "219.168.192.in-addr.arpa" IN {        type master;        file "data/219.168.192.zone";        allow-transfer {192.168.219.147;};        notify yes;        also-notify {192.168.219.147;};  };

3-2、配置從DNS伺服器(192.168.219.147)正向解析

編輯文件/etc/named.rfc1912.zones，在末尾添加需要解析的域

vim /etc/named.rfc1912.zones
zone "panyangduola.com" IN {  　　type slave;  　　file "data/panyangduola.com.zone";  　　masters { 192.168.219.146; };  };

創建panyangduola.com.zone空文件

touch /var/named/data/panyangduola.com.zone

設置所有者　　

cd /var/named/data  chown named:named panyangduola.com.zone

3-3、配置從DNS伺服器(192.168.219.147)反向解析

在文件/etc/named.rfc1912.zones中添加

vim etc/named.rfc1912.zones
zone "219.168.192.in-addr.arpa" IN {      type slave;      file "data/219.168.192.zone";      masters { 192.168.219.146; };　　　  };

創建空文件219.168.192.zone

touch /var/named/data/219.168.192.zone

設置所有者

cd /var/named/data  chown named:named 219.168.192.zone

3-4、對DNS配置文件進行一下語法檢查：

cd /etc  named-checkconf named.conf  named-checkconf named.rfc1912.zones

3-5、編輯/etc/resolv.conf，添加

vim /etc/resolv.conf
search localdomain  nameserver 192.168.219.147

3-6、如果3-4步驟沒有錯誤發生的話，啟動named服務

重啟named

systemctl restart named

查看狀態

systemctl status named

3-7、查看文件/var/named/data/panyangduola.com.zone和/var/named/data/219.168.192.zone是否有二進位數據

cat /var/named/data/panyangduola.com.zone  cat /var/named/data/219.168.192.zone

3-8、檢查從DNS伺服器解析是否成功

ping命令驗證

ping -c 4 www.panyangduola.com

nslookup命令驗證

nslookup  >192.168.219.147
