Mysql 4.1 Windows 下升级问题
类别: PHP教程 
使用PHPMYADMIN时报错：
Client does not support authentication protocol requested
by server; consider upgrading MySQL client
官方的说法是
MySQL 4.1 and up uses an authentication protocol based on a password hashing algorithm that is incompatible with that used by older clients. .....
如果你升级mysql到4.1以上版本后遇到以上问题,请先确定你的mysql client 是4.1或者更高版本.(WINDOWS下有问题你就直接跳到下面看解决方法了,因为MYSQL 在WINDOWS是client和server一起装上了的)
请使用以下两种方法之一
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;
