1.先看一下錯誤提示：（出現此類問題肯定是配置文件有問題，仔細檢查配置文件）
[root@localhost named]# systemctl restart named
Job for named.service failed. See 'systemctl status named.service' and 'journalctl -xn' for details.
log的錯誤提示：

2.這幾個錯誤提示肯定是配置文件那個地方有問題，先檢查了以下主配置文件"/etc/named.conf"這個就修改了兩個any所以只要不是手殘基本不會出問題，其次就是"/etc/named.rfc1912.zones"區域配置文件看看有沒有問題，最后就是數據配置文件了，按順序檢查完發現我的數據配置文件寫錯了。配置如下：腦殘了，不知道咋寫成這樣了，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.重啟直接搞定：
[root@localhost named]# systemctl restart named
[root@localhost named]#
