mysqlnd cannot connect to MySQL 4.1+ using the old insecure authentication. Please use an administration tool to reset your password with the command SET PASSWORD = PASSWORD(‘your_existing_password’). This will store a new, and more secure, hash value in mysql.user. 

使用phpadmin連接上遠(yuǎn)程數(shù)據(jù)庫，執(zhí)行以下sql即可：

SET SESSION old_passwords=FALSE;
 
SET PASSWORD = PASSWORD('yourpassword');
