DNS简单配置

要安装的bind* 、caching-nameserver 包   1、/var/named/chroot/etc/named.conf 这个文件需要自己创建 options {
        listen-on port 53 { 192.168.0.9; };
        directory       "/var/named";
        dump-file       "/var/named/data/cache_dump.db";
        statistics-file "/var/named/data/named_stats.txt";
        memstatistics-file "/var/named/data/named_mem_stats.txt";
        allow-query     { 192.168.0.0/24; };
}; zone "." IN {
        type hint;
        file "named.ca";
}; zone "test.com" IN {
        type master;
        file "test.com.zone";
}; zone "0.168.192.in-addr.arpa" IN {
        type master;
        file "0.168.192.in-addr.arpa.zone";
};   检验： named-checkconf /var/named/chroot/etc/named.conf   2、/var/named/chroot/var/named/test.com.zone 正向解析 $TTL    86400
@               IN SOA mail.test.com.   root.test.com. (
                                        2009060500      ; serial (d. adams)
                                        3H              ; refresh
                                        15M             ; retry
                                        1W              ; expiry
                                        1D )            ; minimum @               IN NS           mail.test.com.
mail            IN A            192.168.0.9
@               IN MX 5         mail.test.com.
mail            IN A            192.168.0.9
www             IN A            192.168.0.99   检验： named-checkzone test.com /var/named/chroot/var/named/test.com.zone   3、/var/named/chroot/var/named/0.168.192.in-addr.arpa.zone 反向解析 $TTL    86400
@               IN SOA mail.test.com.   root.test.com. (
                                        2009060500      ; serial (d. adams)
                                        3H              ; refresh
                                        15M             ; retry
                                        1W              ; expiry
                                        1D )            ; minimum @               IN NS           mail.test.com.
9               IN PTR          mail.test.com.
@               IN MX 5         mail.test.com.
9               IN PTR          mail.test.com.
99              IN PTR          www.test.com.   named-checkzone test.com /var/named/chroot/var/named/0.168.192.in-addr.arpa.zone   4、主意文件的权限是644
/var/named/chroot/var/named/
-rw-r--r-- 1 root  root   306 Jul 15 04:08 0.168.192.in-addr.arpa.zone
-rw-r--r-- 1 root  root   300 Jul 15 03:57 test.com.zone /var/named/chroot/etc/
-rw-r--r-- 1 root root   486 Jul 15 03:27 named.conf
  5、更改你的/etc/resolv.conf nameserver 192.168.0.9   6、测试 dig -t soa test.com dig -t mx michael.com dig mail.michael.com dig -x 192.168.0.9 nslookup   ********************************************************************   辅助DNS   1、在主的DNS named.conf 加一条 allow-transfer  {192.168.0.8;};  意思是允许8这台机器复制主DNS文件   2、8这台机named.conf的配置   options {
        directory       "/var/named";
        }; zone "test.com" IN {
        type slave;
        file "slaves/test.com.zone";
        masters { 192.168.0.9; };
}; zone "0.168.192.in-addr.arpa" IN {
        type slave;
        file "slaves/0.168.192.in-addr.arpa.zone";
        masters { 192.168.0.9; };
};   3、重启named服务后，如果成功的话在 /var/named/chroot/ver/named/slaver 下会出现两个文件，是从主DNS那里复杂过来的。如果不成功，有可能是iptables的问题。   -rw-r--r-- 1 named named 464 03-09 19:21 0.168.192.in-addr.arpa.zone
-rw-r--r-- 1 named named 427 03-09 19:20 test.com.zone   4、修改 /etc/resolv.conf ，改变成 nameserver 127.0.0.1   5、然后测试下，没问题就是成功了！   ********************************************************************   添加多条网段DNS   options {
        listen-on port 53 { 192.168.0.9; };
        directory       "/var/named";
        allow-transfer  {192.168.0.8;};
        dump-file       "/var/named/data/cache_dump.db";
        statistics-file "/var/named/data/named_stats.txt";
        memstatistics-file "/var/named/data/named_mem_stats.txt";
        allow-query     { 192.168.0.0/24; };
}; zone "." IN {
        type hint;
        file "named.ca";
}; zone "test.com" IN {
        type master;
        file "test.com.zone";
}; zone "0.168.192.in-addr.arpa" IN {
        type master;
        file "0.168.192.in-addr.arpa.zone";
};   zone "dony.boob" IN {
        type master;
        file "dony.boob.zone";
}; zone "1.168.192.in-addr.arpa" IN {
        type master;
        file "1.168.192.in-addr.arpa.zone";
}; zone "yoyo.boob" IN {
        type master;
        file "yoyo.boob.zone";
}; zone "2.168.192.in-addr.arpa" IN {
        type master;
        file "2.168.192.in-addr.arpa.zone";
};   添加相应的正反向文件，   -rw-r--r-- 1 root  root   399 Jul 18 06:05 0.168.192.in-addr.arpa.zone
-rw-r--r-- 1 root  root   321 Jul 18 06:48 1.168.192.in-addr.arpa.zone
-rw-r--r-- 1 root  root   228 Jul 18 07:18 2.168.192.in-addr.arpa.zone
