一、安装bind:
yum -y install bind bind-devel bind-utils bind-libbind-devel caching-nameserver

二、配置bind:
cp /etc/named.rfc1912.zones  /etc/named.conf
chown root:named /etc/named.conf
修改主配置文件如下：
zone "." {
    type hint;
    file  "named.local";
};
options{
            directory  "/var/named";
            pid-file "/var/run/named/named.pid";
            listen-on {192.16.1.100;};
            listen-on {127.0.0.1;};
            tcp-clients 3500;
            recursion no;
            version "None";
            allow-transfer { none; };
};
logging {
  channel query_log {
  file "/var/named/logs/named.log" versions 3 size 20m;
    severity info;
    print-time yes;
    print-category yes;
    print-severity yes;
};
category queries {
  query_log;
  };
};
zone "baidu.net" IN {    =========>区域文件
        type master;
        file "/var/named/zone/baidu.net.zone";
        allow-update { none; };
};

cd  /var/named/
dig > named.root（需要上网才行）
vim /var/named/zone/baidu.net.zone
$ttl 600
eqifa.net.        IN    SOA     ns.baidu.net.  root.baidu.net. (
                        1077273781
                        1080
                        3600
                        604800
                        600 )
baidu.net.              IN      NS      ns.baidu.net.
www1                    IN      A       192.168.1.101
www2                    IN      A       192.168.1.102
chown  root:named -R /var/named
