MySQL 错误 1251问题描述:
连接Mysql时,当密码正确时提示1251错误:
#1251 – Client does not support authentication protocol requested by server; consider upgrading MySQL client
密码不正确时,则提示:
#1045 – Access denied for user ‘root’@’localhost’ (using password: NO)
mysql 错误 1251问题原因:
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.
mysql 错误 1251 的解决方法:打开mysql客户端,输入以下两种方法之一即可
第一种:SET PASSWORD FOR ‘dbuser’@”localhost”=OLD_PASSWORD(‘yourPassword’);
第二种:mysql> UPDATE mysql.user SET Password = OLD_PASSWORD(‘newpwd’)-> WHERE Host = ‘some_host’ AND User = ‘some_user’;mysql> FLUSH PRIVILEGES;
