mysql4.1以上版本连接时,提示错误:Client does not support authentication protocol
shell> mysql
Client does not support authentication protocol requested by 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.
方法一:
mysql> SET PASSWORD FOR
-> 'some_user'@'some_host' = OLD_PASSWORD('newpwd');
mysql> FLUSH PRIVILEGES;
方法二:
mysql> UPDATE mysql.user SET Password = OLD_PASSWORD('newpwd')
-> WHERE Host = 'some_host' AND User = 'some_user';
mysql> FLUSH PRIVILEGES;
