　　MySQL(和PHP搭配之最佳组合)4.1以上版本连接时出现Client does not support authentication protocol问题解决办法
shell> MySQL(和PHP搭配之最佳组合)
Client does not support authentication protocol requested
by server; consider upgrading MySQL(和PHP搭配之最佳组合) client

官方的说法是

MySQL(和PHP搭配之最佳组合) 4.1 and up uses an authentication protocol based on a password hashing algorithm that is incompatible with that used by older clients. .....




如果你升级MySQL(和PHP搭配之最佳组合)到4.1以上版本后遇到以上问题,请先确定你的MySQL(和PHP搭配之最佳组合) client 是4.1或者更高版本.(WINDOWS下有问题你就直接跳到下面看解决方法了,因为MySQL(和PHP搭配之最佳组合) 在WINDOWS是client和server一起装上了的)

请使用以下两种方法之一

其一:

MySQL(和PHP搭配之最佳组合)> SET PASSWORD FOR
-> 'some_user'@'some_host' = OLD_PASSWORD('newpwd');

其二:

MySQL(和PHP搭配之最佳组合)> UPDATE MySQL(和PHP搭配之最佳组合).user SET Password = OLD_PASSWORD('newpwd')
-> WHERE Host = 'some_host' AND User = 'some_user';
MySQL(和PHP搭配之最佳组合)> FLUSH PRIVILEGES;

上面的部分请按自己实际情况修改....
这样做后,连接就会正常了@!
