一步步从Win2k DNS 移植到 Linux 下

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
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。

现在你可以把原来的NS服务器格式化，装个XP打CS啦。。。
