在MySQL中修改一个用户(比如叫"hunte")的密码,可以用如下3个办法: >>> #在控制台上输入 bash$ mysql -u root mysql #用mysql客户程序 mysql> UPDATE user SET password=PASSWORD("new password") WHERE user='hunte'; mysql> FLUSH PRIVILEGES; mysql> QUIT <<< >>> #在控制台上输入 bash$ mysql -u root mysql mysql> SET PASSWORD FOR hunte=PASSWORD('new password'); mysql> QUIT <<< >>> #直接在控制台上输入 bash$ mysqladmin -u root "old password" "new password" <<<
