Please note that this post doesn’t cover How to reset mysql root password if you are forgotten.
Recently I noticed that, its quite simple to change the root password of the mysql. mysqladmin command is quite handy for this.
mysqladmin -u<username> -p password <new password>
Here substitute <username> with root and <new password> with your new root password. Since we are passing -p option to the command, it will prompt for your old password.
Enter your old password and you are done.
Thanks for reading.
