Mysql4.1Windows下升级问题_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;
