在 Alpine Linux 3 底下安裝 Bind 當 DNS

採用 PVE 內提供的 alpine-3.14 (2.5MB) 建立 CT

安裝 BIND

apk add bind

設定 /etc/bind/named.conf

options {
  directory "/var/bind";
  pid-file "/var/run/named/named.pid";
  listen-on { 127.0.0.1; 10.20.0.0/24; };
  allow-query { localhost; 0.0.0.0/0; };
  recursion yes;
  max-cache-size 218M;
  allow-recursion { 127.0.0.1/32; 10.0.0.0/8; };
  forwarders { 1.1.1.1; };
};

驗證設定是否沒問題

named-checkconf

設定開機啟動與啟動 DNS 服務

rc-update add named
rc-service named start

設定 /etc/bind/named.conf

建立 named 的 log 路徑

mkdir /var/log/named
chown -R named:named /var/log/named

重新啟動 named

rc-service named restart

在 /var/log/named 內就可以看到產生上面定義的 log 檔案, 主要的查詢紀錄會出現在 /var/log/named/queries.log 內
