UBUNTU12.04服务器版配置dns服务器步骤
操作系统:ubuntu1204服务器版
DNS软件:bind9
newoa.qyjob.net指向168.168.168.96的IP
运行以下命令安装
sudo apt-get install bind9 dnsutils bind9-doc
在默认情况下。Bind9是被配置为DNS缓存服务器来使用的。因此只要把DNS服务器地址加入转发列表就行了
sudo vim /etc/bind/naemd.conf.options
红色是要修改的
- options {
- directory "/var/cache/bind";
- // If there is a firewall between you and nameservers you want
- // to talk to, you may need to fix the firewall to allow multiple
- // ports to talk. See http://www.kb.cert.org/vuls/id/800113
- // If your ISP provided one or more IP addresses for stable
- // nameservers, you probably want to use them as forwarders.
- // Uncomment the following block, and insert the addresses replacing
- // the all-0's placeholder.
- forwarders {
- 210.21.4.130;
- };
- //========================================================================
- // If BIND logs error messages about the root key being expired,
- // you will need to update your keys. See https://www.isc.org/bind-keys
- //========================================================================
- dnssec-validation auto;
- auth-nxdomain no; # conform to RFC1035
- listen-on-v6 { any; };
- };
然后配置主DNS服务器
创建正向zone文件
sudo vim /etc/bind/named.conf.local
添加以下的内容
- zone "qyjob.net" {
- type master;
- file "db.qyjob.net";
- };
sudo cp /etc/bind/db.local /var/cache/bind/db.qyjob.net
sudo vim /var/cache/bind/db.qyjob.net
- $TTL 604800
- @ IN SOA qyjob.net. root.qyjob.net. (
- 2 ; Serial
- 604800 ; Refresh
- 86400 ; Retry
- 2419200 ; Expire
- 604800 ) ; Negative Cache TTL
- ;
- @ IN NS localhost.
- @ IN A 127.0.0.1
- newoa IN A 168.168.168.96
- @ IN AAAA ::1
sudo /etc/init.d/bind9 restart 然后测试就可以发现newoa.qyjob.net已经是做好DNS指向的了。
暂时不想做反向DNS,要做的自己找资料。
第一步:打开DNS缓存和转发:编辑/etc/bind/named.conf.option文件,开启forwarders并在里面填入正确的上游DNS服务器也就是ISP给的服务器形如:
forwarders{202.96.128.86;};
一、Bind 主要文件
/etc/bind/named.conf.local
①编辑named.conf.local
添加下列语句
//反向区域
zone “1.168.192.in-addr.arpa”{
type master;
file “/etc/bind/db.192.168.1″;
};
//正向区域
zone “hp6515b.com”{
type master;
file “/etc/bind/db.hp6515b.com”;
};
②在/etc/bind下建立db.192.168.1文件
; db.192.168.1
;
$TTL 604800
@ IN SOA www.hp6515b.com. root.hp6515b.com. (
1 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;
@ IN NS www.hp6515b.com.
122 IN PTR bbs.hp6515b.com.
193 IN PTR xp.hp6515b.com.
③在/etc/bind下建立hp6515b.com文件; db.hp6515b.com
;
$TTL 604800
@ IN SOA www.hp6515b.com. root.hp6515b.com. (
1 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL;
@ IN NS www.hp6515b.com.
www IN A 192.168.1.122
bbs IN CNAME www
xp.hp6515b.com. IN A 192.168.1.193
(4)重新启动 named
sudo /etc/init.d/bind9 restart
到此位置dns就配置完成了,你可以用nslookup去试试看
注意:改动配置文件后都要重新启动bind9。
三、注意事项与技巧
1、 ubuntu 一般不用root登入 修改文件,创建文件方法
例:sudo vi /etc/bind/named.conf.local
创建文件 sudo vi /etc/bind/db.192.168.1
2、/etc/resolv.conf/ 下域名服务器要设计一下如: nameserver 192.168.1.122
