include \ 重启服务进行测试：

[root@xuegod63 chroot]# cd

[root@xuegod63 ~]# service named restart

Stopping named:

. [ OK ] Starting name

d: [ OK ] [root@xuegod63 ~]# 从DNS服务器：

rm -rf /var/named/chroot/var/named/slaves/xuegod.cn.zone.file

ls /var/named/chroot/var/named/slaves/ 测试工具：

nslookup 测试域名解析 (1)非交互式模式

语法： nslookup 域名或IP 地址
