——安装DNS服务软件

＃yum -y install bind-chroot.x86_64

——修改/etc/named.conf文件

[root@httpd ~]# vim /etc/named.conf
options {directory  "/var/named";                          
};
zone  "lcf.com" {                                  type  master;                                     file  "lcf.com.zone";                             
};

——创建/var/name/lcf.com.zone文件

$TTL 1D                                         
@   IN SOA  @ rname.invalid. (0   ; serial1D  ; refresh1H  ; retry1W  ; expire3H )    ; minimum
@       NS  svr7.lcf.com    
@       A   192.168.1.5                     
svr7    A   192.168.4.7                         
svr7    A   192.168.4.207                         
*       A   192.168.4.100

——重启服务测试

[root@httpd ~]# systemctl restart named
在另一台机设置DNS为ＤＮＳ的服务器IP

#host ser7.lcf.com
