基础概念
Cache-only DNS
DNS缓存服务器不存在自定义的zone文件, 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.confoptions { 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
