centos+dns

原创 centos 5.2 下 dns  安装

 

1、安装软件

 

yum install -y bind*

yum install -y system-config-bind

yum install -y caching-nameserver

 

2、配置 named.conf  文件

 

cd /var/named/chroot/etc

 

[root@server etc]# ls
localtime  named.caching-nameserver.conf  named.conf  named.rfc1912.zones  rndc.key

 

cp -p  named.caching-nameserver.conf  named.conf 

 

chmod 777 named.conf

 

vim named.conf

 

 

options {
        listen-on port 53 { any; };
        listen-on-v6 port 53 { ::1; };
        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";

        // Those options should be used carefully because they disable port
        // randomization
        // query-source    port 53;
        // query-source-v6 port 53;

        allow-query     { any; };
        allow-query-cache { any; };
};
logging {
        channel default_debug {
                file "data/named.run";
                severity dynamic;
        };

};
view localhost_resolver {
        match-clients      { any; };
        match-destinations { any; };
        recursion yes;
        include "/etc/named.rfc1912.zones";
};

3、配置 named.rfc1912.zones

 

在  named.rfc1912.zones  文件最下面添加

 

zone "frank.com" IN {
      type master;
      file "frank.com.zone";
      allow-update { none; };
};
zone "0.168.192.in-addr.arpa" IN {
        type master;
        file "0.168.192.zone";
        allow-update { none; };
};

4、配置 frank.com.zone

 

cd /var/named/chroot/var/named

 

[root@server named]# ls
0.168.192.zone  frank.com.zone    localhost.zone   named.ca         named.local  slaves
data            localdomain.zone  named.broadcast  named.ip6.local  named.zero

 

cp -p localhost.zone  frank.com.zone 

 

 

[root@server named]# cat frank.com.zone
$TTL    86400
@               IN SOA  @       root (
                                    42          ; serial (d. adams)
                                    3H          ; refresh
                                    15M         ; retry
                                    1W          ; expiry
                                    1D )                ; minimum

                IN NS           @
                IN A            127.0.0.1
                IN AAAA         ::1
www             IN A           192.168.0.2
mail            IN A           192.168.0.2
ftp             IN A           192.168.0.2

    

 

5、配置 0.168.192.zone

 

cp -p named.local     0.168.192.zone 

 

[root@server named]# cat 0.168.192.zone
$TTL    86400
@       IN      SOA     localhost. root.localhost.  (
                                      1997022700 ; Serial
                                      28800      ; Refresh
                                      14400      ; Retry
                                      3600000    ; Expire
                                      86400 )    ; Minimum
        IN      NS      localhost.
1       IN      PTR     localhost.
2       IN      PTR     www.frank.com.
2       IN      PTR     mail.frank.com.
2       IN      PTR     ftp.frank.com.

 

6、设置硬链接到 /var/named 目录下

 

ln frank.com.zone /var/named

ln 0.168.192.zone /var/named

 

7、设置 resolv.conf

[root@server named]# cat /etc/resolv.conf
# MADE-BY-RP-PPPOE
nameserver 192.168.0.2
nameserver 202.96.134.133

 

 

8、测试

service named restart

 

[root@server named]# nslookup www.frank.com
Server:         192.168.0.2
Address:        192.168.0.2#53

Name:   www.frank.com
Address: 192.168.0.2

成功！
