1.先看一下错误提示：（出现此类问题肯定是配置文件有问题，仔细检查配置文件）
[root@localhost named]# systemctl restart named
Job for named.service failed. See 'systemctl status named.service' and 'journalctl -xn' for details.
log的错误提示：

Nov 30 14:25:31 localhost named-checkconf: zone adamkuo.com/IN: not loaded due to errors.

2.这几个错误提示肯定是配置文件那个地方有问题，先检查了以下主配置文件"/etc/named.conf"这个就修改了两个any所以只要不是手残基本不会出问题，其次就是"/etc/named.rfc1912.zones"区域配置文件看看有没有问题，最后就是数据配置文件了，按顺序检查完发现我的数据配置文件写错了。配置如下：脑残了，不知道咋写成这样了，正向也不是反向也不是
$TTL 1D
@ IN SOA adamkuo.com. root.adamkuo.com. (
0 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
NS ns.adamkuo.com.
ns IN A 192.168.2.128
@ IN MX 10 mail.adamkuo.com.
mail IN A mail.adamkuo.com.
www IN A www.adamkuo.com.
bbs IN A bbs.adamkuo.com.
3.修改完成后配置如下：
$TTL 1D
@ IN SOA adamkuo.com. root.adamkuo.com. (
0 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
NS ns.adamkuo.com.
ns IN A 192.168.2.128
@ IN MX 10 mail.adamkuo.com.
mail IN A 192.168.2.128
www IN A 192.168.2.128
bbs IN A 192.168.2.128
4.重启直接搞定：
[root@localhost named]# systemctl restart named
[root@localhost named]#
