centos7.x 部署主、從DNS伺服器問題
1、準備
例：兩臺192.168.219.146(主), 192.168.219.147(從), 域名www.panyangduola.com
主、從DNS伺服器均需要安裝bind、bind-chroot、bind-utils
yum -y install bind bind-utils bind-chroot
如果防火牆開啟，配置防火牆，新增服務(防火牆已禁用則忽略)
firewall-cmd --permanent --add-service=dns firewall-cmd --reload
2、主DNS伺服器(192.168.219.146)配置
編輯配置檔案
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
編輯檔案/etc/named.rfc1912.zones，在末尾新增需要解析的域
vim /etc/named.rfc1912.zones
zone "panyangduola.com" IN {
type master;
file "data/panyangduola.com.zone";
};建立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
編輯檔案/etc/named.rfc1912.zones，在末尾新增需要解析的域
vim /etc/named.rfc1912.zones
zone "219.168.192.in-addr.arpa" IN {
type master;
file "data/219.168.192.zone";
};
建立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配置檔案進行一下語法檢查：
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，新增
vim /etc/resolv.conf search localdomain nameserver 192.168.219.146
2-5、如果2-3步驟沒有錯誤發生的話，啟動named服務
重啟named
systemctl restart named
檢視狀態
systemctl status named
2-6、檢查主DNS伺服器解析是否成功
ping命令驗證
ping -c 4 www.panyangduola.com nslookup命令驗證 nslookup >www.panyangduola.com nslookup >192.168.219.146
3、從DNS伺服器(192.168.219.147)配置
編輯named.conf檔案
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伺服器(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伺服器(192.168.219.147)正向解析
編輯檔案/etc/named.rfc1912.zones，在末尾新增需要解析的域
vim /etc/named.rfc1912.zones
zone "panyangduola.com" IN {
type slave;
file "data/panyangduola.com.zone";
masters { 192.168.219.146; };
};
建立panyangduola.com.zone空檔案
touch /var/named/data/panyangduola.com.zone
設定所有者
cd /var/named/data chown named:named panyangduola.com.zone
3-3、配置從DNS伺服器(192.168.219.147)反向解析
在檔案/etc/named.rfc1912.zones中新增
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; };
};
建立空檔案219.168.192.zone
touch /var/named/data/219.168.192.zone
設定所有者
cd /var/named/data chown named:named 219.168.192.zone
3-4、對DNS配置檔案進行一下語法檢查：
cd /etc named-checkconf named.conf named-checkconf named.rfc1912.zones
3-5、編輯/etc/resolv.conf，新增
vim /etc/resolv.conf search localdomain nameserver 192.168.219.147
3-6、如果3-4步驟沒有錯誤發生的話，啟動named服務
重啟named
systemctl restart named
檢視狀態
systemctl status named
3-7、檢視檔案/var/named/data/panyangduola.com.zone和/var/named/data/219.168.192.zone是否有二進位制資料
cat /var/named/data/panyangduola.com.zone cat /var/named/data/219.168.192.zone
3-8、檢查從DNS伺服器解析是否成功
ping命令驗證 ping -c 4 www.panyangduola.com nslookup命令驗證 nslookup >192.168.219.147
