主题:从 win2k DNS 转移到 linux 下 (原创)

最近公司到DNS server总是出问题， 于是下决心转移到linux下，但是里面有200多个域埃想来想去，总结出如下一套办法，供大家参考。如有不足网大家指正。



一、准备工作：



首先进入win2k, DNS 服务管理器，选 查看--列表；

然后导出列表到一个文件： mydomain.txt



注意，正反向解析域都要导出，合并到同一个文件里mydomain.txt



进入 \winnt\system32\dns 将所有文件打包，和mydomain.txt 一起复制到linux下。





二、开始迁移：



1、生成配置文件：



主域配置文件：

执行如下脚本：



#!/usr/bin/perl

##################################################################

$configfile = "/etc/named.conf";

$dnsfile = "/var/named";

$importfile = "mydomain.txt";





system("/bin/echo > $configfile");



open(OUTFILE,">>$configfile");

flock (OUTFILE,2);

print OUTFILE "options {\n";

print OUTFILE " directory \"$dnsfile\";\n";

print OUTFILE " forwarders {\n";

print OUTFILE " 202.96.199.133;\n";

print OUTFILE " 202.96.209.5;\n";

print OUTFILE " };\n";

print OUTFILE "};\n";

print OUTFILE "zone \".\" {\n";

print OUTFILE " type hint;\n";

print OUTFILE " file \"named.ca\";\n";

print OUTFILE "};\n";



open(INFILE,$importfile);

@lines = <INFILE>;



$num=0;

foreach $line (@lines) {



chop ($line);

print OUTFILE "zone \"$line\" {\n";

print OUTFILE " type master;\n";

print OUTFILE " file \"$line.dns\";\n";

print OUTFILE "};\n";



$num ++;

}

close(INFILE);

close (OUTILE);

print "$num Record convert!!\n";



exit;



生成备份域配置文件： 执行这个脚本：



#!/usr/bin/perl

##################################################################

$configfile = "/etc/named.conf";

$dnsfile = "/var/named";

$importfile = "mydomain.txt";

$masterns = "1.1.1.";



system("/bin/echo > $configfile");



open(OUTFILE,">>$configfile");

flock (OUTFILE,2);

print OUTFILE "options {\n";

print OUTFILE " directory \"$dnsfile\";\n";

print OUTFILE " forwarders {\n";

print OUTFILE " 202.96.199.133;\n";

print OUTFILE " 202.96.209.5;\n";

print OUTFILE " };\n";

print OUTFILE "};\n";

print OUTFILE "zone \".\" {\n";

print OUTFILE " type hint;\n";

print OUTFILE " file \"named.ca\";\n";

print OUTFILE "};\n";



open(INFILE,$importfile);

@lines = <INFILE>;



$num=0;

foreach $line (@lines) {



chop ($line);

print OUTFILE "zone \"$line\" {\n";

print OUTFILE " type slave;\n";

print OUTFILE " file \"$line.dns\";\n";

print OUTFILE " masters { $masterns; };\n";

print OUTFILE "};\n";



$num ++;

}

close(INFILE);

close (OUTILE);

print "$num Record convert!!\n";



exit;



2、复制DNS记录：将从windows下复制过来到dns文件复制到 /var/named 下；



主备域此操作相同。



3、在/var/named下执行：



mv CACHE.DNS named.ca #配置文件windows和linux命名不同。

chown named:named * #更改所有者

chmod 644 * #更改权限





4、编辑 /etc/resolv.conf 如下：



search mydomain.com.cn

domain mydomain.com.cn

nameserver 1.1.1.1

nameserver 202.96.199.133

nameserver 202.96.209.5





5、启动named服务。 /etc/init.d/named start

6、关闭原来的NS服务器。

7、将linux服务器的IP改成win2k的IP。





OK 完成啦。。



现在你可以把原来的NS服务器格式化，装个XP打CS啦。。。
