部署主DNS服务器

安装bind
  yum install bind-chroot bind-utils -y

迭代查询 返回dns服务器地址
递归查询 返回查询结果

修改主配置文件
  vim /etc/named.conf

修改zone文件属主属组
  chown root.named /var/named/192.68.121.arpa
  chown root.named /var/named/8kb24.cn.zone

启动named
  systemctl enable named
  systemclt start named

开放防火墙端口
  firewall-cmd --zone=public --permanent --add-port=53/tcp
  firewall-cmd --zone=public --permanent --add-port=53/udp
  firewall-cmd --reload

部署从DNS服务器

安装bind
  yum install -y bind-chroot bind-utils -y 

修改主DNS服务器配置文件
  vim /etc/named.rfc1912.zones

 1 zone "8kb24.cn" IN {
 2     type master;
 3     file "8kb24.cn.zone";
 4     allow-update { 192.168.121.12; };
 5 };
 6 
 7 
 8 zone "121.168.192.in-addr.arpa" IN {
 9     type master;
10     file "192.168.121.arpa";
11     allow-update {192.168.121.12; };
12 };

 

修改从DNS服务器配置文件
  vim  /etc/named.rfc1912.zones

 1 zone "8kb24.cn" IN {
 2     type slave;
 3     masters { 192.168.121.11; };

 9     masters { 192.168.121.11;};
10     file "slaves/192.168.121.arpa";
11 };

 

启动从DNS服务器
  systemctl enable named
  systemctl start named

重启主DNS服务器
  systemctl restart named

[root@Sdns slaves]# ll /var/named/slaves
total 8
-rw-r--r-- 1 named named 385 Sep 22 15:12 192.168.121.arpa

主从服务器加密传输
  主DNS服务器生成密钥
    root@Mdns ~]# dnssec-keygen -a HMAC-MD5 -b 128 -n HOST chenxiaowei
    Kchenxiaowei.+157+53919

    [root@Mdns ~]# cat Kchenxiaowei.+157+53919.key
    chenxiaowei. IN KEY 512 3 157 xRVknXER5gnr4QL1r8atlg==
  创建密钥文件(主从服务器都一样)
  vim /var/named/chroot/etc/chenxiaowei.key

1 key "chenxiaowei" {
2     algorithm hmac-md5;
3     secret "xRVknXER5gnr4QL1r8atlg==";
4 };

 

  chown root.named /var/named/chroot/etc/chenxiaowei.key
  ln /var/named/chroot/etc/chenxiaowei.key /etc/

  修改主DNS服务器的配置文件
  vim /etc/named.conf

include "/etc/chenxiaowei.key";
options {
        listen-on port 53 { any; };
        directory       "/var/named";
        dump-file       "/var/named/data/cache_dump.db";
        statistics-file "/var/named/data/named_stats.txt";
        memstatistics-file   "/var/named/data/named_mem_stats.txt";
        allow-query     { any; };
        allow-transfer {key chenxiaowei; };
        forwarders{8.8.8.8;};

 

  修改从DNS服务器的配置文件
  vim /etc/named.conf

1 include "/etc/chenxiaowei.key";
2 server 192.168.121.11
3 { keys { chenxiaowei ;} ;};

 

重启主从服务器named服务
  systemctl restart named 

分散解析
  vim /etc/named.rfc1912.zones
