Jan 30 03:45:48 hh-yun-puppet-129021 named[100639]: transfer of '199.10.in-addr.arpa/IN' from 10.199.132.152#53: Transfer completed: 23 messages, 2201 records, 96020 bytes, 0.027 secs (3556296 bytes/sec)

原因: master 服务器上具有不合法的语法解析, 导致 bind 无法主从同步获取完整的数据信息

解决方法,  检测主服务器数据库上的  records 表中 name 与 content 字段, 细心找到不合法的字段, 然后修复则可解决.

如:

mysql> select * from records where name='21.130.199.10.in-addr.arpa';   (不符合规范语法, 不知道谁埋的雷)

mysql> delete from records where id=4;
Query OK, 1 row affected (0.00 sec)

mysql> select * from records where type='SOA' and domain_id=2;  (正确语法参考)
