内网配置DNS服务器，无域名，只有主机名

Hadoop集群中，使用DNS而不是hosts来访问服务器。

1. 安装bind软件

用root用户运行：

yum -y install bind*

2. 配置named.conf文件

vi /etc/named.conf

修改以下部分：

listen-on port 53 { any; };

allow-query     { any; };

修改完毕后继续修改/etc下面的另一文件。

3. 添加正向和反向的域名

vi /etc/named.rfc1912.zones

zone "." IN {
        type master;
        file "hadoop.com.zone";
        allow-update { none; };
};

zone "44.168.192.in-addr.arpa" IN {
        type master;
        file "192.168.44.zone";
        allow-update { none; };
};

4. 编辑正向和反向两个文件

vim /var/named/hadoop.com.zone

$TTL 1D
@     IN SOA  com. root.hadoop.com. (
                                       0       ; serial
                                       1D      ; refresh
                                       1H      ; retry
                                       1W      ; expire
                                       3H )    ; minimum
      NS    @

service bind restart
