1、準(zhǔn)備
例：兩臺192.168.219.146(主), 192.168.219.147(從), 域名www.panyangduola.com
主、從DNS服務(wù)器均需要安裝bind、bind-chroot、bind-utils
yum -y install bind bind-utils bind-chroot
如果防火墻開啟，配置防火墻，添加服務(wù)(防火墻已禁用則忽略)
firewall-cmd --permanent --add-service=dns
firewall-cmd --reload
2、主DNS服務(wù)器(192.168.219.146)配置
編輯配置文件
vim /etc/named.conf
找到其中兩行
listen-on port 53 { 127.0.0.1; };
allow-query { localhost; };
修改為
listen-on port 53 { any; };
allow-query { any; };
2-1、配置正向解析
編輯文件/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";
};
創(chuàng)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
編輯文件/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";
};
創(chuàng)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、對DNS配置文件進(jìn)行一下語法檢查：
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、編輯/etc/resolv.conf，添加
vim /etc/resolv.conf
search localdomain
nameserver 192.168.219.146
2-5、如果2-3步驟沒有錯(cuò)誤發(fā)生的話，啟動(dòng)named服務(wù)
重啟named
systemctl restart named
查看狀態(tài)
systemctl status named
2-6、檢查主DNS服務(wù)器解析是否成功
ping命令驗(yàn)證
ping -c 4 www.panyangduola.com
nslookup命令驗(yàn)證
nslookup
>www.panyangduola.com
nslookup
>192.168.219.146
3、從DNS服務(wù)器(192.168.219.147)配置
編輯named.conf文件
vim /etc/named.conf
找到其中兩行
listen-on port 53 { 127.0.0.1; };
allow-query { localhost; };
修改為
listen-on port 53 { any; };
allow-query { any; };
3-1、修改主DNS服務(wù)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、配置從DNS服務(wù)器(192.168.219.147)正向解析
編輯文件/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; };
};
創(chuàng)建panyangduola.com.zone空文件
touch /var/named/data/panyangduola.com.zone
設(shè)置所有者
cd /var/named/data
chown named:named panyangduola.com.zone
3-3、配置從DNS服務(wù)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; };
};
創(chuàng)建空文件219.168.192.zone
touch /var/named/data/219.168.192.zone
設(shè)置所有者
cd /var/named/data
chown named:named 219.168.192.zone
3-4、對DNS配置文件進(jìn)行一下語法檢查：
cd /etc
named-checkconf named.conf
named-checkconf named.rfc1912.zones
3-5、編輯/etc/resolv.conf，添加
vim /etc/resolv.conf
search localdomain
nameserver 192.168.219.147
3-6、如果3-4步驟沒有錯(cuò)誤發(fā)生的話，啟動(dòng)named服務(wù)
重啟named
systemctl restart named
查看狀態(tài)
systemctl status named
3-7、查看文件/var/named/data/panyangduola.com.zone和/var/named/data/219.168.192.zone是否有二進(jìn)制數(shù)據(jù)
cat /var/named/data/panyangduola.com.zone
cat /var/named/data/219.168.192.zone
3-8、檢查從DNS服務(wù)器解析是否成功
ping命令驗(yàn)證
ping -c 4 www.panyangduola.com
nslookup命令驗(yàn)證
nslookup
>192.168.219.147
