【求助】2003下MySql安装求助

当然硬盘都是NTFS 以前我用FAT32，数据库也是4。0 没出现过这个问题 我装了mysql 4.1.8 后利用PHPMYADMIN 修改root密码 ，修改密码后 改了config 文件无法连上。我想我的密码应该没设错。改了密码后 就是连不上。

我不知道你用的是那个版本的phpmyadmin,目前最新版本已经是2.6了，我们下载回来是不能直接用的，需要做一些小修改才可以，发现很多新手还是不知道的，这里写了一个傻瓜教程，十分简单，就以下4步：



=====================================================

1

找到 $cfg['PmaAbsoluteUri']



在后面的''内把phpMyAdmin的地址打上，修改后如 $cfg['PmaAbsoluteUri'] = 'http://www.china.com/china';





2

找到 $cfg['blowfish_secret']



在后面的''内随便输入一些数字或字母，修改后如 $cfg['blowfish_secret'] = 'china';





3

找到 $cfg['Servers'][$i]['auth_type']



后面的''内默认为config，修改为cookie，修改后如 $cfg['Servers'][$i]['auth_type'] = 'cookie';





4

找到 $cfg['Servers'][$i]['user']

后面的''内默认是root，去掉，修改后如 $cfg['Servers'][$i]['user'] = '';

错误提示是什么？

好的，非常感谢 回去我试一下

$cfg['Servers'][$i]['user'] = ''; 原来这里也可以不填啊？

这是4.1X版本后HASH算法改变造成的.重新转换下就好.



SET PASSWORD FOR 用户名@localhost = OLD_PASSWORD('密码');

官方解答:

MYSQL 帮助：

A.2.3 Client does not support authentication protocol

MySQL 4.1 and up uses an authentication protocol based on a password hashing algorithm that is incompatible with that used by older clients. If you upgrade the server to 4.1, attempts to connect to it with an older client may fail with the following message:



shell> mysql

Client does not support authentication protocol requested

by server; consider upgrading MySQL client



To solve this problem, you should use one of the following approaches:



Upgrade all client programs to use a 4.1.1 or newer client library.

When connecting to the server with a pre-4.1 client program, use an account that still has a pre-4.1-style password.

Reset the password to pre-4.1 style for each user that needs to use a pre-4.1 client program. This can be done using the SET PASSWORD statement and the OLD_PASSWORD() function:

mysql> SET PASSWORD FOR

-> 'some_user'@'some_host' = OLD_PASSWORD('newpwd');



Alternatively, use UPDATE and FLUSH PRIVILEGES:

mysql> UPDATE mysql.user SET Password = OLD_PASSWORD('newpwd')

-> WHERE Host = 'some_host' AND User = 'some_user';

mysql> FLUSH PRIVILEGES;



Substitute the password you want to use for ``newpwd'' in the preceding examples. MySQL cannot tell you what the original password was, so you'll need to pick a new one.

Tell the server to use the older password hashing algorithm:

Start mysqld with the --old-passwords option.

Assign an old-format password to each account that has had its password updated to the longer 4.1 format. You can identify these accounts with the following query:

mysql> SELECT Host, User, Password FROM mysql.user

-> WHERE LENGTH(Password) > 16;



For each account record displayed by the query, use the Host and User values and assign a password using the OLD_PASSWORD() function and either SET PASSWORD or UPDATE, as described earlier.

For additional background on password hashing and authentication, see section 5.5.9 Password Hashing in MySQL 4.1.





例子：

SET PASSWORD FOR 用户名@localhost = OLD_PASSWORD('密码');

mydql4.1.9在安装字符集时，应该怎么选择？



GB2312吗？

用PHPMYADMIN 修改root密码

我在安装完mysql4.1.10后,用PHPMYADMIN怎么登录不了,提示要升级client端?怎么升级?

6楼的有道理的啊
