dns--主从区域文件配置

区别在于type类型上一个为master一个为slave，从需要指定master服务器地址，masterfile-format text这个参数为同步时不会产生乱码--也可以配置在主文件上，就不用每个区域文件都配置了

1、主配置文件

zone "goo.com" IN {
      type master;
      file "db.goo.com";
};
zone "gooagoo.com" IN {
       type master;
       file "db.gooagoo.com";
};

zone "gooagoo.cn" IN {
       type master;
       file "db.gooagoo.cn";
};

2、从配置文件

zone "goo.com" IN {
      type slave;
      file "slaves/db.goo.com";
      masterfile-format text;
      masters { 192.168.10.10; };
};
zone "gooagoo.com" IN {
      type slave;
      file "slaves/db.gooagoo.com";
      masterfile-format text;
      masters { 192.168.10.10; };
};
