PHP远程链接mysql报错处理办法

在万网弄了个虚拟主机，想远程连mysql调试(本地4G若是开mysql内存不够！)，一直报错：

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. If this user is used in other scripts executed by PHP 5.2 or earlier you might need to remove the old-passwords flag from your my.cnf file

解决方法以下：

SET old_passwords = 0;
SET PASSWORD = PASSWORD('estudyadmin123');
FLUSH PRIVILEGES;
