毗连数据库呈现
-------------------------------------------------------------------------------------------
Client does not support authentication protocol requested
by server; consider upgrading MySQL client
-------------------------------------------------------------------------------------------
因为MySQL 4.1版本入手下手暗码的hash算法改动，所以毗连数据库
时能够会呈现Client does not support authentication protocol成绩。
可以经由过程一下两种办法处理
其一:
mysql> SET PASSWORD FOR
-> 'some_user'@'some_host' = OLD_PASSWORD('newpwd');
其二:
mysql> UPDATE mysql.user SET Password = OLD_PASSWORD('newpwd')
-> WHERE Host = 'some_host' AND User = 'some_user';
mysql> FLUSH PRIVILEGES;
