If it doesn't match, php must be recompiled with the current version of mysql. 1) First ensure you have the require rpms:[root@server ~]# rpm -qa | grep MySQL MySQL-server-4.1.12-1 MySQL-client-4.1.12-1 MySQL-shared-4.1.12-1 MySQL-devel-4.1.12-1 [root@server ~]#You'll need to be able to see all 4 of those rpms, and all 4 must have the same version.

It is easy to solve this issue though. First goto the MySQL Server machine or if it is not accessible, then SSH or remote desktop to the server machine. Next in that server, login to your server locally and reach the mysql prompt. Then run this command SET PASSWORD FOR 'username'@'IPordomain' = old_PASSWORD('userpassword'); Here replace username with your username and replace IPordomain with the IP from which you will be logging in later. Then replace userpassword with your password. That's it. You can now login again from your PC. What you just did is to let MySQL server know that you are still using the old password hashing mechanism for that particular user.

on Apache with suPHP (I'll blog about this later). While testing my PHP 4 build, I got the following error: Warning: mysql_connect() [function.mysql-connect]: Client does not support authentication protocol requested by server; consider upgrading MySQL client in /var/www/test-php.php on line 3 Couldn't authenticate with MySQL The code I used to test this is quite simple: if ( false === ( $db = mysql_connect( 'localhost', 'username', 'password' ) ) ) die( "Couldn't authenticate with MySQL" ); if ( false === mysql_select_db( 'database' ) ) die( "Couldn't connect to database" ); echo "Yay!"; ?> After digging around for a bit, I found that mixing PHP 4 with a MySQL version greater than or equal to 4.1 causes this problem. MySQL 4.1 introduced a new password caching scheme that PHP 4 can't work with. The solution is to update the database user's password using the OLD_PASSWORD function of MySQL. For example: [chris@office ~]$ mysql -u root -p mysql Enter password: Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 267 Server version: 5.1.41-3ubuntu12.1 (Ubuntu) Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. mysql> update user set Password=OLD_PASSWORD('password') WHERE User='username'; Query OK, 0 rows affected (0.02 sec) Rows matched: 0 Changed: 0 Warnings: 0 mysql> flush privileges; Query OK, 0 rows affected (0.00 sec) mysql> Note the underlined areas. That is where you'll want to provide your own username and password. Once you've followed these steps, both PHP 4 and PHP 5 will be able to communite with the database. Thanks to digitalpeer for providing the answer to my issue. Did I help you? Send me a tip. Categories : Linux Comments rasheed says: March 26, 2011 at 5:27 am OLD PASSWORD you mean which password ? Reply Chris Jean says: April 4, 2011 at 8:55 am OLD_PASSWORD is a MySQL function. Reply Jurij says: June 8, 2016 at 3:29 am Worked for me. Thanks a lot!
