Mysql#1251错误
<p>问题描述：<br/>连接Mysql时，当密码正确时提示1251错误：<br/>#1251 - Client does not support authentication protocol requested by server; consider upgrading MySQL client<br/>密码不正确时，则提示：<br/>#1045 - Access denied for user <a href="mailto:'root'@'localhost'">'root'@'localhost'</a> (using password: NO)</p><p>原因:<br/>由于MySQL 4.1 及其后版本验证协议使用的密码哈希算法与老的客户端不兼容,在PHPMYADMIN里用正确密码登陆也会提示：#1251错误.</p><p>解决方法：打开mysql客户端，输入以下两种方法之一即可<br/>第一种：SET PASSWORD FOR <a href="mailto:'dbuser'@"localhost"=OLD_PASSWORD('yourPassword'">'dbuser'@"localhost"=OLD_PASSWORD('yourPassword'</a>);</p><p>第二种：mysql> UPDATE mysql.user SET Password = OLD_PASSWORD('newpwd')-> WHERE Host = 'some_host' AND User = 'some_user';mysql> FLUSH PRIVILEGES; </p>
