虚拟机作为DNS服务器端

服务器端：

一、装包

yum -y install bind bind-utils bind-chroot

二、启动服务

systemctl start named
systemctl start named-chroot
systemctl start named-chroot-setup

三、修改配置文件

chroot服务将DNS服务器禁锢在/var/named/chroot/中，也就是DNS服务器将>/var/named/chroot/当成自己的家目录 

存放主配置文件的目录：/var/named/chroot/etc/
存放从配置文件的目录：/var/named/chroot/var/named
 

#cd /var/named/chroot/etc/
#cat /dev/null>named.conf //删除之前的配置文件
#vim named.conf //编辑主配置文件
opoptions{
directory "/var/named";
};
zone "youngfit.cn." IN{
type master;
file "youngfit.cn.zone";
};
#chown named.named named.conf
#cd /var/named/chroot/var/named
#touch youngfit.cn.zone //编辑从配置文件
