shell> mysql
Client does not support authentication protocol requested
by 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(jí)mysql到4.1以上版本后遇到以上問題,請(qǐng)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?yàn)镸YSQL 在WINDOWS是client和server一起裝上了的)
請(qǐng)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;
上面紅色的部分請(qǐng)按自己實(shí)際情況修改....
這樣做后,連接就會(huì)正常了@!
php技術(shù)：mysql4.1以上版本連接時(shí)出現(xiàn)Client does not support authentication protocol問題解決辦法，轉(zhuǎn)載需保留來源！
