shell> mysql
Client does not support authentication protocol requested
by server; consider upgrading MySQL client

如果你升級mysql到4.1以上版本後遇到以上問題,請先確定你的mysql client 是4.1或者更高版本.(WINDOWS下有問題你就直接跳到下面看解決方法了,因為MYSQL 在WINDOWS是client和server一起裝上了的)

其一:

mysql> SET PASSWORD FOR
    -> '' = OLD_PASSWORD('');

mysql> UPDATE mysql.user SET Password = OLD_PASSWORD('')
    -> WHERE Host = '' AND User = ';
mysql> FLUSH PRIVILEGES;

上面紅色的部分請按自己實際情況修改....

這樣做後,連線就會正常了@!
