1、准备

例：两台192.168.219.146(主), 192.168.219.147(从), 域名

主、从DNS服务器均需要安装bind、bind-chroot、bind-utils

yum -y install bind bind-utils bind-chroot

如果防火墙开启，配置防火墙，添加服务(防火墙已禁用则忽略)

firewall-cmd --permanent --add-service=dnsfirewall-cmd --reload

2、主DNS服务器(192.168.219.146)配置

编辑配置文件

vim /etc/named.conf

找到其中两行

listen-on port 53 { 127.0.0.1; };allow-query { localhost; };

修改为

listen-on port 53 { any; };allow-query { any; };

2-1、配置正向解析

编辑文件/etc/named.rfc1912.zones，在末尾添加需要解析的域

vim /etc/named.rfc1912.zoneszone "panyangduola.com" IN { type master; file "data/panyangduola.com.zone";};

创建panyangduola.com.zone解析域

vim /var/named/data/panyangduola.com.zone$TTL 3600$ORIGIN panyangduola.com.@ IN SOA panyangduola.com. admin.panyangduola.com. ( 2018042101 1D 1H 1W 3H)@ IN NS ns1.panyangduola.com.@ IN NS ns2.panyangduola.com.ns1 IN A 192.168.219.146ns2 IN A 192.168.219.147www IN A 192.168.219.146web IN CNAME www

2-2、配置反向解析

编辑文件/etc/named.rfc1912.zones，在末尾添加需要解析的域

vim /etc/named.rfc1912.zoneszone "219.168.192.in-addr.arpa" IN { type master; file "data/219.168.192.zone"; };

创建219.168.192.zone解析域

vim /var/named/data/219.168.192.zone$TTL 3600$ORIGIN 219.168.192.in-addr.arpa.@ IN SOA panyangduola.com. admin.panyangduola.com. ( 2018042101 1D 1H 1W 3H)@ IN NS ns1.panyangduola.com.@ IN NS ns2.panyangduola.com.146 IN PTR ns1.panyangduola.com.147 IN PTR ns2.panyangduola.com.146 IN PTR .

2-3、对DNS配置文件进行一下语法检查：

cd /etcnamed-checkconf named.confnamed-checkconf named.rfc1912.zonescd /var/named/datanamed-checkzone panyangduola.com panyangduola.com.zonenamed-checkzone 219.168.192.in-addr.arpa 219.168.192.zone

2-4、编辑/etc/resolv.conf，添加

vim /etc/resolv.confsearch localdomainnameserver 192.168.219.146

2-5、如果2-3步骤没有错误发生的话，启动named服务

重启named

systemctl restart named

查看状态

systemctl status named

2-6、检查主DNS服务器解析是否成功

ping命令验证

ping -c 4 nslookup命令验证nslookup>nslookup>192.168.219.146

3、从DNS服务器(192.168.219.147)配置

编辑named.conf文件

vim /etc/named.conf

找到其中两行　　

listen-on port 53 { 127.0.0.1; }; 　　allow-query { localhost; };

修改为

listen-on port 53 { any; };allow-query { any; };

3-1、修改主DNS服务器(192.168.219.146)的配置/etc/named.rfc1912.zones

vim /etc/named.rfc1912.zoneszone "panyangduola.com" IN { type master; file "data/panyangduola.com.zone"; allow-transfer {192.168.219.147;}; notify yes; also-notify {192.168.219.147;};};zone "219.168.192.in-addr.arpa" IN { type master; file "data/219.168.192.zone"; allow-transfer {192.168.219.147;}; notify yes; also-notify {192.168.219.147;}; };

3-2、配置从DNS服务器(192.168.219.147)正向解析

编辑文件/etc/named.rfc1912.zones，在末尾添加需要解析的域

vim /etc/named.rfc1912.zoneszone "panyangduola.com" IN {　　type slave;　　file "data/panyangduola.com.zone";　　masters { 192.168.219.146; };};

创建panyangduola.com.zone空文件

touch /var/named/data/panyangduola.com.zone

设置所有者　　

cd /var/named/datachown named:named panyangduola.com.zone

3-3、配置从DNS服务器(192.168.219.147)反向解析

在文件/etc/named.rfc1912.zones中添加

vim etc/named.rfc1912.zoneszone "219.168.192.in-addr.arpa" IN { type slave; file "data/219.168.192.zone"; masters { 192.168.219.146; };　　　};

创建空文件219.168.192.zone

touch /var/named/data/219.168.192.zone

设置所有者

cd /var/named/datachown named:named 219.168.192.zone

3-4、对DNS配置文件进行一下语法检查：

cd /etcnamed-checkconf named.confnamed-checkconf named.rfc1912.zones

3-5、编辑/etc/resolv.conf，添加

vim /etc/resolv.confsearch localdomainnameserver 192.168.219.147

3-6、如果3-4步骤没有错误发生的话，启动named服务

重启named

systemctl restart named

查看状态

systemctl status named

3-7、查看文件/var/named/data/panyangduola.com.zone和/var/named/data/219.168.192.zone是否有二进制数据

cat /var/named/data/panyangduola.com.zonecat /var/named/data/219.168.192.zone

3-8、检查从DNS服务器解析是否成功

ping命令验证ping -c 4 nslookup命令验证nslookup>192.168.219.147
