How to change mysql root password on Linux

1. Stop mysql Service
   sudo systemctl stop mysql

tep by step instructions:

1. Start off by stopping the MySQL service:
   sudo systemctl stop mysql
2. Now, we need to restart the MySQL service but without password privileges being granted. Note that the & at the end of the command just runs the service in the background and will allow us to continue using the current terminal.
   sudo mysqld_safe --skip-grant-tables &
3. You’ll now be able to connect to the MySQL server as root, without specifying a password: mysql -u root
4. Now, reset the root password, but first flush the privileges to reload the grants:mysql>
   FLUSH PRIVILEGES;
   mysql> use mysql;
   mysql> update user set plugin=“mysql_native_password“ where User=’root‘;
   mysql> ALTER USER ‚root’@’localhost‘ IDENTIFIED BY ’new_password_here‘;
   mysql> FLUSH PRIVILEGES;
   mysql> quit;
5. Finally, shut down the MySQL service and start it back up.$ sudo systemctl restart mysql
