你可以尝试以下步骤来重置mysql的root密码:

首先停止Mysql服务

sudo /etc/init.d/mysql stop 

以root用户登录，不需要密码 Sudo mysqld_safe—skip-grant-tables &

登录mysql终端后，你需要执行更多的命令:

use mysql;




UPDATE mysql.user SET authentication_string=PASSWORD('solutionclub3@*^G'), plugin='mysql_native_password' WHERE User='root';


flush privileges;


sudo mysqladmin -S /var/run/mysqld/mysqld.sock shutdown

重启mysql服务器后 如果你仍然面临错误，你必须访问: 重置MySQL的root密码

当更改/重置MySQL密码时，上面列出的以下命令没有帮助。我发现进入终端并使用这些命令是毫无意义的。相反，使用命令sudo停止一切。如果有帮助的话，删除windows的system32。

对我有用的(Ubuntu 16.04, mysql 5.7):

停止MySQL

sudo service mysql stop

制作MySQL服务目录。

sudo mkdir /var/run/mysqld

赋予MySQL用户写入服务目录的权限。

sudo chown mysql: /var/run/mysqld

手动启动MySQL，不需要权限检查或联网。

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

在另一个控制台，无需密码登录。

mysql -uroot mysql

然后:

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

关闭MySQL。

sudo mysqladmin -S /var/run/mysqld/mysqld.sock shutdown

正常启动MySQL服务。

sudo service mysql start

对于mysql 5.6，这个命令有效，你可以通过向导设置密码:

sudo dpkg-reconfigure mysql-server-5.6

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.

如果部署在xampp上，您可以通过提供的phpadmin gui轻松更改mysql密码。

phpMyAdmin -> User Accounts -> Edit Privileges (Select the intended user) -> Change Password (Tab)
