1.yum install -y bind
2.不要安装bind-chroot（安装了文件配置就在/etc/var/chroot/etc/下面）
3.dns配置文件位置：
/etc/named.conf
/etc/named.rfc1912.zones
4.配置/etc/named.conf
F:\资料\ediary\ediary文件连接\named.conf.docx
5.配置/etc/named.rfc1912.zone
F:\资料\ediary\ediary文件连接\named.rfc1912.zones.docx
6.创建区域解析文件
mkdir /var/named
cd /var/named/
touch luocs.com.zone
chown -R .named /var/named
7.配置区域文件luocs.com.zone
F:\资料\ediary\ediary文件连接\luocs.com.zone.docx
8.配置//etc/resolv.conf
search localdomain
nameserver 192.168.100.30
启动named服务
/etc/init.d/named restart
