如果你知道“root”用户密码，请使用该凭证登录mysql。然后执行以下查询以更新密码。

ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_passowrd';

如果你想修改MySQL root密码，在终端输入:

Sudo dpkg-reconfigure mysql-server-5.5

MySQL守护进程将被停止，并提示您输入新密码。

Instead of resetting the password there is a work around on the local machine if you have setup phpmyadmin to connect without giving the password or username. Check this out by starting mysql, apache etc. I have xampp installed in my local machine. So starting the xampp will start all the necessary services. Now going to http://localhost/phpmyadmin shows me all the databases. This confirms that you have saved the username and passsword in the config file of phpmyadmin which can be found in the phpmyadmin install location. If you have xampp installed the phpmyadmin folder can be found in the root folder of xampp installation. Search for the word password in the config.inc.php file. There you will find the password and username.

你不需要这些。只需登录:

Mysql -u root -p

然后按照mysql>提示修改当前用户的密码:

mysql> set password=password('the_new_password');
mysql> flush privileges;

您可以使用该命令:

UPDATE mysql.user SET Password=PASSWORD('newpwd') WHERE User='root';

之后请冲洗:

FLUSH PRIVILEGES;
