在我的例子中，这个选项很有用:https://stackoverflow.com/a/49610152/13760371 谢谢你，拉胡尔。

除了下面的时刻，当我尝试输入命令:

UPDATE mysql.user SET authentication_string=PASSWORD('YOURNEWPASSWORD'), plugin='mysql_native_password' WHERE User='root' AND Host='%';

控制台发出警告:

1681 'password' is deprecated and will be removed in a future release

用这个命令治愈:

UPDATE mysql.user SET authentication_string=CONCAT('*', UPPER(SHA1(UNHEX(SHA1('NEWPASSWORD'))))), plugin='mysql_native_password' WHERE User='root' AND Host='localhost';

MySQL版本5.7.X

我的版本:

1. > sudo service mysql stop
2. > sudo mkdir /var/run/mysqld
3. > sudo chown mysql: /var/run/mysqld
4. > sudo mysqld_safe --skip-grant-tables --skip-networking &
5. > mysql -uroot mysql
6. > UPDATE mysql.user SET authentication_string=CONCAT('*', UPPER(SHA1(UNHEX(SHA1('NEWPASSWORD'))))), plugin='mysql_native_password' WHERE User='root' AND Host='localhost';
7. > \q;
8. > sudo mysqladmin -S /var/run/mysqld/mysqld.sock shutdown
9. > sudo service mysql start

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.

重置或修改密码请输入sudo dpkg-reconfigure mysql-server-X。X (X.X是mysql版本你已经安装，即5.6,5.7)，然后你会提示一个屏幕，你必须设置新密码，然后在下一步确认密码，只是等待一会儿。就是这样。

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';

我分享一步一步的最终解决方案，重置MySQL密码在Linux Ubuntu。

参考来自博客(dbrnd.com)

步骤1: 停止MySQL服务。

sudo stop mysql

步骤2: 关闭所有运行mysqld。

sudo killall -9 mysqld

步骤3: 以安全模式启动mysqld。

sudo mysqld_safe --skip-grant-tables --skip-networking &

步骤4: 启动mysql客户端

mysql -u root

步骤5: 登录成功后，如果需要修改密码，请执行该命令。

FLUSH PRIVILEGES;

步骤6: 您可以更新mysql root密码。

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

注意:在MySQL 5.7中，Password列被称为authentication_string。

第七步: 请执行该命令。

FLUSH PRIVILEGES;
