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 $TTL 86400 @ IN SOA clear-vm.youngfit.cn. root.youngfit.cn (        100000000          1M        15M        1W        1D)        IN NS clear-vm.youngfit.cn. clear-vm   IN A 10.18.44.70 www.youngfit.cn.
