1、准备
例：两台192.168.219.146(主), 192.168.219.147(从), 域名www.panyangduola.com
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=dns firewall-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.zones
zone "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 192.168.219.146 ns2 IN A 192.168.219.147 www IN A 192.168.219.146 web 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.zones
zone "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 www.panyangduola.com.
2-3、对DNS配置文件进行一下语法检查：
cd /etc named-checkconf named.conf named-checkconf named.rfc1912.zones cd /var/named/data named-checkzone panyangduola.com panyangduola.com.zone named-checkzone 219.168.192.in-addr.arpa 219.168.192.zone
2-4、编辑/etc/resolv.conf，添加
vim /etc/resolv.conf search localdomain nameserver 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 www.panyangduola.com nslookup命令验证 nslookup >www.panyangduola.com 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.zones
zone "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.zones
zone "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/data chown 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.zones
zone "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/data chown named:named 219.168.192.zone
3-4、对DNS配置文件进行一下语法检查：
cd /etc named-checkconf named.conf named-checkconf named.rfc1912.zones
3-5、编辑/etc/resolv.conf，添加
vim /etc/resolv.conf search localdomain nameserver 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.zone cat /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 www.panyangduola.com nslookup命令验证 nslookup >192.168.219.147
