出现这种问题也只有在MYSQL4.1.x以上版本,用4.0.x就没问题了.
原因是因为你使用的mysql服务器版本中使用了新的密码验证机制,这需要客户端的版本要在4.0以上,原来的密码函数被改为old_password ();,这样使用password()生成的密码在旧的版本上的客户端就不好使了,而PHP中的MYSQL客户端都是3.23的(当然,mysqli的扩展除外),问题就在这了。目前已知解决方法(假设密码是123,mysql存放在d盘):
1. 进入命令行下,转到MYSQL目录的BIN目录下,进入MYSQL命令行模式(用户root,密码123):
d:\mysql\bin>mysql -uroot -p123
2. 输入命令:
mysql>set password for 'root'@'localhost'=old_password('123');
3. 退出MYSQL命令行:
mysql>\q
至此可正常使用新密码了。
