一直也没有机会接触dns，最近终于有机会亲自操刀了，为了到时不至于慌忙，这两天有时间自己安装了一下，简单把我的安装过程记录如下
需求也不是很大:
1，通过这个dns可以解析其他域名
2，通过这个dns解析我自己设定的域名及二级子域名
可以到dns到bind-9.4.2.tar.gz
tar zxvf bind-9.4.2.tar.gz
cd bind-9.4.2
./configure --enable-threads --enable-largefile --disable-openssl-version-check --prefix=/usr/local/named
make && make install
cd /usr/local/named/
sbin/rndc-confgen > etc/rndc.conf
tail -10 rndc.conf |head -9|sed s/#\ //g >named.conf
cd /usr/local/named/var
mkdir named
cd named/
建立localhost.zone，内容如下
$TTL 3h
@ IN SOA @ root (
20080530 ；序列号
3h ；3小时后刷新
1h ；1小时后重试
1w ；1周后期满
1h ) ；否定缓存TTL为1小时
IN NS loaclhost.
IN A 127.0.0.1
|
建立ptr.127.0.0文件，内容如下
$TTL 3h
@ IN SOA localhost. root.localhost. (
20080530
3h
1h
1w
1h )
IN NS localhost.
1 IN PTR localhost.
|
接下来是建立我自己的一个域名，mosquito.edu的zone文件
mosquito.edu.zone，内容如下：
$TTL 3h
@ IN SOA linux01 root.mosquito (
20080530
3h
1h
1w
1h )
IN NS linux01
www IN A 192.168.153.130
|
建立ptr.192.168.153文件，内容如下
$TTL 3h
@ IN SOA linux01.mosquito.edu. root.mosquito.edu. (
20080530
3h
1h
1w
1h )
IN NS linux01.mosquito.edu.
130 IN PTR linux01.mosquito.edu.
|
接下来建立named.root文件，内容如下

; instructions to get a fresher copy of it.

; initialize cache of Internet domain name servers

cd /usr/local/named/etc
vi named.conf添加如下内容
options {
directory "/usr/local/named/var/named";
allow-query-cache { any; };
pid-file "named.pid";
};
zone "." IN {
type hint;
file "named.root";
};
zone "localhost" IN {
type master;
file "localhost.zone";
allow-update{none;};
};
zone "0.0.127.in-addr.arpa" IN {
type master;
file "ptr.127.0.0";
};
zone "mosquito.edu" IN {
type master;
file "mosquito.edu.zone";
};
zone "153.168.192.in-addr.arpa" IN {
type master;
file "ptr.192.168.153";
};

至此配置文件都准备完毕了，使用/usr/local/named/sbin/named -c /usr/local/named/etc/named.conf 启动dns
可以从/var/log/messages文件中查看dns启动的情况
接下了可以测试了，现在dns上进行
dig @localhost
返回结果如下
;; AUTHORITY SECTION:
sina.com.cn. 86400 IN NS ns1.sina.com.cn.
sina.com.cn. 86400 IN NS ns3.sina.com.cn.
sina.com.cn. 86400 IN NS ns2.sina.com.cn.
;; ADDITIONAL SECTION:

;; Query time: 601 msec
;; SERVER: 127.0.0.1#53(127.0.0.1) 由此看到是由本机dns解析的了

dig @localhost
;; ANSWER SECTION:

;; AUTHORITY SECTION:
mosquito.edu. 10800 IN NS linux01.mosquito.edu.
;; Query time: 29 msec
;; SERVER: 127.0.0.1#53(localhost) 同样可以返回正确的结果

看来我自己的域名也可以正确的解析了，接下来看看反向情况
host 192.168.153.130
[root@linux01 etc]# host 192.168.153.130
130.153.168.192.in-addr.arpa domain name pointer linux01.mosquito.edu.
|
然后可以把另外一台电脑的dns改成这台的ip进行测试，经过我自己的测试是正常的，测试返回的结果我就不贴出来了
