快速搭建BIND服务,并实现解析
公司有测试需求,当连接一个网络后自动会进入产品的测试环境,所以搭建了一个DNS解析服务,来完成此需求。
参考:http://blog.chinaunix.net/uid-30149335-id-5069146.html 找了个教程参考了一下,然后根据自己需求更改
一、安装BIND
yum install -y bind cp /etc/named.conf /etc/named.conf.bak >/etc/named.conf vim /etc/named.conf
加入如下配置:
options { directory "/var/named"; }; zone "." IN { type hint; file "named.ca"; }; zone "localhost" IN { type master; file "localhost.zone"; }; zone "0.0.127.in-addr.arpa" IN { type master; file "named.local"; };
chown named /etc/named.conf #如果属组是named可以不改 cd /var/named/ dig -t NS . > named.ca
vim localhost.zone //加入
@ IN SOA localhost. admin.localhost. ( 2013081601 1H 10M 7D 1D ) @ IN NS localhost. localhost. IN A 127.0.0.1
vim named.local //加入
$TTL 86400 @ IN SOA localhost. admin.localhost. ( 2013081601 1H 10M 7D 1D ) @ IN NS localhost. 1 IN PTR localhost
rndc-confgen -r /dev/urandom -a // 这一步是生成 rndc.key, 如果没有这个key namd 是启动不了的 ####话说我也没测试到底能不能启动。。。
检测配置是否有问题: named-checkconf
netstat -lnp |grep named // 查看一下named进程是否监听了53端口
/etc/init.d/named start #看看能不能起来,没起来的话根据报错去解决,起来的话就能正常解析了
二、增加一个域名(zone) 备:这就是我的需求,需要把产品的域名解析到我们的测试机上,增加一个域名解析
vim /etc/named.conf ##请根据自己的域名及IP更改
zone "hotel.test.com" IN { type master; file "hotel.test.com.lan"; }; zone "10.168.192.in-addr.arpa" IN { type master; file "10.168.192.db"; };
cd /var/named/
vi hotel.test.com
$TTL 86400 @ IN SOA ns.hotel.test.com. root.hotel.test.com. ( 2007041501 ;Serial 3600 ;Refresh 1800 ;Retry 604800 ;Expire 86400 ;Minimum TTL ) IN NS ns.hotel.test.com. IN A 192.168.10.10 IN MX 10 ns.hotel.test.com. ns IN A 192.168.10.10
vi 10.168.192.db
$TTL 86400 @ IN SOA ns.hotel.test.com. root.hotel.test.com. ( 2007041501 ;Serial 3600 ;Refresh 1800 ;Retry 604800 ;Expire 86400 ;Minimum TTL ) IN NS ns.hotel.test.com. IN PTR hotel.test.com. IN A 255.255.255.0 17 IN PTR ns.hotel.test.com.
把本机DNS改成自己的,然后dig测试一下
[root@TBJ named]# dig hotel.test.com ; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.47.rc1.el6_8.3 <<>> hotel.test.com ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 34986 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 1, ADDITIONAL: 1 ;; QUESTION SECTION: ;hotel.test.com. IN A ;; ANSWER SECTION: hotel.test.com. 86400 IN A 192.168.10.10 ;; AUTHORITY SECTION: hotel.test.com. 86400 IN NS ns.hotel.test.com. ;; ADDITIONAL SECTION: ns.hotel.test.com. 86400 IN A 192.168.10.10 ;; Query time: 0 msec ;; SERVER: 115.182.63.152#53(115.182.63.152) ;; WHEN: Thu Feb 9 17:44:51 2017
完事。
好记性不如烂笔头-_-
