1，环境准备

关闭防火墙，selinux
systemctl stop firewalld
systemctl disabled firewalld
setenforce 0

2，安装服务

yum install bind-* -y

3，修改主服务器配置文件

[root@dns-1 named]# cat /etc/named.conf
//
// named.conf
//
// Provided by Red Hat bind package to configure the ISC BIND named(8) DNS
// server as a caching only nameserver (as a localhost DNS resolver only).
//
// See /usr/share/doc/bind*/sample/ for example named configuration files.
//
// See the BIND Administrator's Reference Manual (ARM) for details about the
// configuration located in /usr/share/doc/bind-{version}/Bv9ARM.html

options {
    listen-on port 53 { any; };    ##此处就是any
    listen-on-v6 port 53 { ::1; };
    directory   "/var/named";
    dump-file   "/var/named/data/cache_dump.db";
    statistics-file "/var/named/data/named_stats.txt";
    memstatistics-file "/var/named/data/named_mem_stats.txt";
    recursing-file  "/var/named/data/named.recursing";
    secroots-file   "/var/named/data/named.secroots";
    allow-query     { any; };  ##此处也是any

     - If you are building a RECURSIVE (caching) DNS server, you need to enable

     - If your recursive DNS server has a public IP address, you MUST enable access

    */
    recursion yes;

    dnssec-enable yes;
    dnssec-validation yes;

    /* Path to ISC DLV key */
    bindkeys-file "/etc/named.root.key";

    managed-keys-directory "/var/named/dynamic";

    pid-file "/run/named/named.pid";
    session-keyfile "/run/named/session.key";
};

logging {
        channel default_debug {
                file "data/named.run";
                severity dynamic;
        };
};

zone "." IN {
    type hint;
    file "named.ca";
};
##下面是自己新加的正向解析，复制上面修改就好
zone "zjht100.com" IN {      ##zjht100.com为自定义
    type master;                   ##角色为master
    file "zjht100.com.zone";    ##指定对应的文件（创建该文件名要相同）
    allow-transfer { none; };
};

include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";

4，创建解析文件

cd /var/named
cp named.localhost zjht100.com.zone
**修改文件权限 **
chown named.named zjht100.com.zone
vim zjht100.com.zone
$TTL 1D
@       IN SOA  @ rname.invalid. (
                                        0       ; serial
                                        1D      ; refresh
                                        1H      ; retry
                                        1W      ; expire
                                        3H )    ; minimum
        NS      @
        A       127.0.0.1
        AAAA    ::1
www     IN      A       192.168.3.252  ##前面不动，此处为新加解析

5，重启服务

systemctl restart named
验证
[root@dns-1 named]# named-checkzone "zjht100.com" /var/named/zjht100.com.zone 
zone zjht100.com/IN: loaded serial 0
OK   ——>输出OK表示正确

6，从DNS配置

        channel default_debug {
                file "data/named.run";
                severity dynamic;
        };
};

zone "." IN {
    type hint;
    file "named.ca";
};
##新加解析

    type slave;     ##此处角色为slave

    masters {192.168.3.234;}; ##此处写master节点IP

7，重启服务

systemctl restart named
