问题：
在客户机（比如192.168.1.20）上远程连接上面192.168.1.152机器的mysql，连接失败！
[root@huanqiu ~]# mysql -udb_ro_hqsb -h 192.168.1.152 -pmhxzkhl0802xqsjdb
ERROR 1130 (HY000): Host '192.168.1.20' is not allowed to connect to this MySQL server
解决：
是由于192.168.1.152的mysql里“host为localhost，user和password为空”这条语句导致的，删除这条即可解决问题！
mysql>
delete
from mysql.user where host="localhost" and user="";
Query OK, 1 row affected (0.00 sec)
mysql>
flush
privileges;
Query OK, 0 rows affected (0.00 sec)
这样，授权连接的客户机就能成功连接了！
[root@huanqiu ~]# mysql -uxqsj_db_ro_user -h 192.168.1.152 -pmhxzkhl0802xqsjdb
