MySQL 4.1 and PHP 4.x

RyanM · #1 11-Dec-2004, 14:37

I'm sorry if this has already been asked. Did a few searches, but the term limit of 4 characters made searching for "4.1" a little difficult.

Using PHP 4.3.9 and MySQL 4.1, I have the following code: (obviously, some of the details like the password and username were changed)

PHP Code:


// This is actually in a separate file which I include.
    $database_host =        '127.0.0.1';
    $database_user =        'thesite';
    $database_password =    'password';
    $database_data =        'teamsite'; // Name of database we should use

// And the code which gives me a problem:
    $connection = mysql_connect($database_host, $database_user, $database_password);

I get

Warning: mysql_connect(): Client does not support authentication protocol requested by server; consider upgrading MySQL client...

I know that I could solve the problem by upgrading to php5, but the hosting service I will be using after development may not upgrade for a while. Is there a way to get this to work?

Try changing your database host '127.0.0.1' to say 'localhost', instead.

I can't see how changing your PHP or MySQL version will make a difference - its just supposed to work from PHP. Are you running this from a Windows system?

Hello RyanM,

I have not updated my MySQL server to the latest version (4.1) yet so I am unable to help you with this particular problem.

However, a quick search on the MySQL website yielded an interesting page full of information I think you can use to fix your problem, at least you can understand why it's happening.

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:... more >>

Thanks JdS!

I got it to work by setting up the old password as stated in the directions.

No, I must thank you instead for asking this question.

At least I will have one less issue to figure out when I upgrade MySQL on my own machine soon.
