MYSQL(解決方法):Client does not support authentication(轉)[@more@]mysql4.1以上版本連接時出現Client does not support authentication protocol問題解決辦法shell> mysqlClient does not support authentication protocol requestedby server; consider upgrading MySQL client官方的說法是MySQL 4.1 and up uses an authentication protocol based on a password hashing algorithm that is incompatible with that used by older clients. .....如果你升級mysql到4.1以上版本后遇到以上問題,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)請使用以下兩種方法之一其一:mysql> SET PASSWORD FOR-> 'some_user'@'some_host' = OLD_PASSWORD('newpwd');其二:mysql> UPDATE mysql.user SET Password = OLD_PASSWORD('newpwd')-> WHERE Host = 'some_host' AND User = 'some_user';mysql> FLUSH PRIVILEGES;上面的部分請按自己實際情況修改....這樣做后,連接就會正常了@
