3.2、创建claylpf.xyz主域名的数据文件
复制代码
[root@dns ~]# cd /var/named/
[root@dns named]# ls
chroot chroot_sdb data dynamic dyndb-ldap named.ca named.empty named.localhost named.loopback slaves
[root@dns named]# cp -a named.localhost claylpf.xyz.zone
[root@dns named]# ls
chroot chroot_sdb claylpf.xyz.zone data dynamic dyndb-ldap named.ca named.empty named.localhost named.loopback slaves
[root@dns named]#
3.3、修改claylpf.xyz.zone文件：
复制代码
[root@dns named]# vim claylpf.xyz.zone
[root@dns named]# cat claylpf.xyz.zone
$TTL 1D
@ IN SOA @ rname.invalid. (
0 ; serial
1D ; refresh

3.4、刷新dns服务
复制代码
[root@dns named]# service named restart
