有人能解释一下这个问题吗，我似乎无法解析我的域名foo.com
root@dns:/etc/bind/zones# nslookup foo.com
Server: 192.168.1.54
Address: 192.168.1.54#53
*** Can't find foo.com: No answer

你可以看到这里foo.com已经加载了。并且我的/etc/resolv.conf也已经配置为nameserver 127.0.0.1
Jun 10 23:20:58 zild-ubuntu named[13703]: zone foo.com/IN: loaded serial 1
答案1
您没有 的 A 记录foo.com，您只有 的 A 记录www.foo.com。
尝试使用 www.foo.com 进行挖掘或添加@ IN A 192.168.1.54到区域文件。
