对于Ubuntu 18.04和mysql版本14.14,Distrib 5.7.22,请按照以下步骤重置mysql密码。
步骤1
sudo systemctl stop mysql
步骤2
sudo systemctl edit mysql
这个命令将在nano编辑器中打开一个新文件,您将使用该文件编辑MySQL的服务覆盖。这些更改MySQL的默认服务参数。该文件将为空,因此添加以下内容:
[Service]
ExecStart=
ExecStart=/usr/sbin/mysqld --daemonize --pid-file=/run/mysqld/mysqld.pid --skip-grant-tables --skip-networking
步骤3
sudo systemctl daemon-reload
sudo systemctl start mysql
步骤4
sudo mysql -u root
步骤5
FLUSH PRIVILEGES;
步骤6
UPDATE mysql.user SET authentication_string = PASSWORD('new_password') WHEREuser = 'root';
步骤7
UPDATE mysql.user SET plugin ='mysql_native_password' WHERE user = 'root';
步骤8
sudo systemctl revert mysql
最后
sudo systemctl restart mysql
现在享受

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)
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.
这就是我的解决方案。我在Ubuntu 18.04工作: https://stackoverflow.com/a/46076838/2400373
但是重要的是最后一步的改变:
UPDATE mysql.user SET authentication_string=PASSWORD('YOURNEWPASSWORD'), plugin='mysql_native_password' WHERE User='root' AND Host='localhost';
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。
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。
