/var/named/chroot/var/named:设备繁忙

Question

当我重新启动命名的服务时，它会给出以下错误：

./etc/init.d/named restart

知道出了什么问题吗？

Answer 1

错误是告诉你到底出了什么问题：

Error in named configuration:
zone enum4red.com/IN: has 0 SOA records
zone enum4red.com/IN: has no NS records
zone enum4red.com/IN: not loaded due to errors.

转到以下目录：

/var/named/chroot/var/named

查看区域enum4red.com的区域文件。
