观察下面的错误时，尝试启动虚拟linux pc中的DNS服务

Mar 04 03:38:44 mininat.benunets.com systemd[1]: Unit named.service entered failed state. 请在下面find我的区域文件
[root@mininat ~]# vi /var/named/benu123.com $TTL 86400 @ IN SOA benu123.com. root( 2010052601 ; serial 3600 ; refresh 1800 ; retry 604800 ; expire 86400 ; minimum ) IN NS benu123.com localhost IN A 127.0.0.1 localhost IN AAAA ::1 benu55 IN AAAA 2001::2222 benu89 IN AAAA 2002::2222 ~
那么你注意到Bind不会启动的原因是由于预启动检查返回的错误条件： /usr/sbin/named-checkconf -z /etc/named.conf 。 你需要解决这个问题。
在你的区域文件结尾的寂寞代字符〜不是一个有效的资源logging，应该被删除。
您正在声明一个区域内名称服务器：
IN NS benu123.com
而无需为您的名称服务器创buildAlogging。 这显然是错误的。 另外一个资源logging不会以. 被视为DNS短手，并获得$ ORIGIN（区域名称）追加，所以你现在有什么function相当于：
IN NS benu123.com.benu123.com.
你可能应该想要这样的东西，而不是：
$ORIGIN benu123.com. $TTL 86400 @ IN SOA benu123.com. root.benu123.com( 2014030401 ; serial 3600 ; refresh 1800 ; retry 604800 ; expire 86400 ; minimum ) IN NS benu123.com. @ IN A 192.168.1.1 ; replace this with the ip-address of your name-server localhost IN A 127.0.0.1 localhost IN AAAA ::1 benu55 IN AAAA 2001::2222 benu89 IN AAAA 2002::2222
我使用@作为另一个DNS速记技巧，它相当于$ ORIGIN或域名benu123.com。
至lessNS条目需要一个A或AAAAlogging（除非你的名字服务器被称为benu123.com.benu123.com，否则最有可能是最后一个点）。
