CentOS 6.2 系统搭建DNS服务器

一、安装软件包
[root@dns /]#yum -y install bind*

二、针对主配置文件name.conf的配置
[root@dns ~]#cd /etc
[root@dns etc]#cp -p named.conf  named.conf.bak
[root@dns etc]#vi named.conf 
//更改过内容以下

options {
        listen-on port 53 { any; };//这里将127.0.0.1改成any.监听全部.
       #listen-on-v6 port 53 { ::1; };//将ipv6注释掉啊。暂无需求.
        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     { any; };//此处修改成any
        recursion yes;

        dnssec-enable yes;
        dnssec-validation yes;
        dnssec-lookaside auto;

  /* Path to ISC DLV key */
        bindkeys-file "/etc/named.iscdlv.key";
};

logging {
        channel default_debug {
                file "data/named.run";
                severity dynamic;
        };

zone "." IN {
        type hint;
        file "named.ca";
};

include "/etc/named.rfc1912.zones";

三、在此目录下还有一个文件要配置，命令以下：
[root@dns etc]#vim /etc/named.rfc1912.zones

zone "localhost.localdomain" IN {
        type master;
        file "named.localhost";
        allow-update { none; };
};

zone "localhost" IN {
        type master;
        file "named.localhost";
        allow-update { none; };
//注意如下为注释内容

#zone "1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa" IN {
#       type master;
#       file "named.loopback";
#       allow-update { none; };
#};

zone "1.0.0.127.in-addr.arpa" IN {
        type master;
        file "named.loopback";
        allow-update { none; };
};

zone "0.in-addr.arpa" IN {
        type master;
        file "named.empty";
        allow-update { none; };
};

//如下是要添加正向的域。根据本身状况添加。个人是zc.com
zone "zc.com" IN {
        type master;
        file "zc.com.zone";
};


四、 配置正向解析文件。

须要新建文件zc.com.zone
[root@dns etc]#cd  /var/named
[root@dns named]#touch ccfafei.com.zone
[root@dns named]#vim zc.com.zone  //添加如下内容保存
@       IN      SOA     zc.com. root.zc.com. (
                                        0       ; serial
                                        1D      ; refresh
                                        1H      ; retry
                                        1W      ; expire
                                        3H )    ; minimum
@       IN      NS      server.zc.com.
server  IN      A       192.168.10.254
host1   IN      A       192.168.10.1
host2   IN      A       192.168.10.2
host3   IN      A       192.168.10.3
host4   IN      A       192.168.10.4

五、将DNS服务器指向这台服务器
六、利用nslookup命令解析server.zc.com、host1.zc.com等等，解析成功说明服务器已经搭建成功。
