出现“Client does not support authentication protocol requested by server”?

安装Mysql4.1以上版本出现“Client does not support authentication protocol requested by server”.

Mysql 4.1及以上版本使用了新的密码算法,而PHP不支持新算法,因此在新增用户后,还需要用下面的方法解决PHP无法连接登录Mysql的问题: (其中some_user,some_host,newpwd分别是您数据库的用户名,主机,密码)

第一种解决方法:

mysql> SET PASSWORD FOR

-> 'some_user'@'some_host' = OLD_PASSWORD('newpwd');

比方说数据库用户是admin,主机localhost,,密码是123456

这时候输入的命令应该是:

mysql> SET PASSWORD FOR admin@localhost=OLD_PASSWORD('123456');

第二种解决方法:

mysql> UPDATE mysql.user SET Password = OLD_PASSWORD('newpwd')

-> WHERE Host = 'some_host' AND User = 'some_user';

mysql> FLUSH PRIVILEGES;

第三种解决方法(不推荐)

用 --old-passwords 选项启用 mysqld,然后用上面的方法更改原有用户
