MYSQL(解决方法):Client does not support authentication(转)

千家信息网最后更新 2026年11月01日MYSQL(解决方法):Client does not support authentication(转)MYSQL(解决方法):Client does not support authentication(转)[@more@]mysql4.1以上版本连接时出现Client does not support authentication protocol问题解决办法shell> mysqlClient does not support authentication protocol requestedby server; consider upgrading MySQL client官方的说法是MySQL 4.1 and up uses an authentication protocol based on a password hashing algorithm that is incompatible with that used by older clients. .....如果你升级mysql到4.1以上版本后遇到以上问题,请先确定你的mysql 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 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> 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;上面的部分请按自己实际情况修改....这样做后,连接就会正常了@
