mysql: blocked because of many connection errors

今天尝试用一台虚拟机去连另一台虚拟机的mysql时出现了报错.
ERROR 1129 (HY000): Host'192.168.2.128' is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts'

这是由于一个ip在短时间内产生太多中断的数据库连接导致的.

解决:
    1.增大连接数
    #vi my.cnf
    max_connections=1000
   > set global max_connections=1000;
 
    2.刷新连接的ip
    # mysqladmin flush-hosts
    > flush hosts;
