基础概念

Cache-only DNS

DNS缓存服务器不存在任何的zone配置文件，仅仅依靠缓存来为客户端提供服务，通常用于负载均衡及加速访问操作.

操作环境

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

搭建步骤

1. 安装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. 语法检查

```
[root@cachedns ~]# named-checkconf 
```

4. 启动named

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