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。。。
