推荐答案

感谢@thusharaK，我可以在不知道旧密码的情况下重置 root 密码.

thanks to @thusharaK I could reset the root password without knowing the old password.

在 ubuntu 上我做了以下事情:

On ubuntu I did the following:

sudo service mysql stop
sudo mysqld_safe --skip-grant-tables --skip-syslog --skip-networking

然后在新终端中运行mysql:

Then run mysql in a new terminal:

mysql -u root

并运行以下查询以更改密码:

And run the following queries to change the password:

UPDATE mysql.user SET authentication_string=PASSWORD('password') WHERE User='root';
FLUSH PRIVILEGES;

在 MySQL 5.7 中，mysql.user 表字段中的密码字段被删除，现在字段名称为authentication_string".

退出mysql安全模式，启动mysql服务:

Quit the mysql safe mode and start mysql service by:

mysqladmin shutdown
sudo service mysql start
