基礎概念

Cache-only DNS

DNS緩存服務器不存在自定義的zone文件, 僅依靠緩存來為客戶端提供服務, 通常用於負載均衡及加速訪問操作.

操作環境

HOSTNAME	IP ADDRESS	ROLE
mac	192.168.199.103	DNS Client
cachedns.zakzhu.com	192.168.199.173	Cache-only DNS

搭建步驟

1. 安裝bind

• [root@cachedns ~]# yum install bind -y
  

2. 修改/etc/named.conf

• [root@cachedns ~]# vim /etc/named.conf
  

  options {
      listen-on port 53 { 192.168.199.173; };
  		listen-on-v6 port 53 { ::1; };
          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";
          recursing-file  "/var/named/data/named.recursing";
          secroots-file   "/var/named/data/named.secroots";
      allow-query     { any; };
      forward only;
      forwarders { 223.5.5.5; 223.6.6.6; };
          recursion yes;
      dnssec-enable no;
      dnssec-validation no;
          bindkeys-file "/etc/named.root.key";
          managed-keys-directory "/var/named/dynamic";
          pid-file "/run/named/named.pid";
          session-keyfile "/run/named/session.key";
  };
  ... ...
  ... ...
  

3. 語法檢查

• [root@cachedns ~]# named-checkconf 
  

4. 啟動named

• [root@cachedns ~]# systemctl enable named
  [root@cachedns ~]# systemctl restart named
