This is a question I have heard (too) many time. How does one reset the root MySQL password on Ubuntu. In order to make this as simple as possible I created a shell script (you can see it below) that does just that.
What does it do?
I’m glad you ask, because just trusting someone on the internet probably isn’t such a great idea. I have added a couple of comments to the script in order to make it more readable, so please look over it before you use it.
Here is exactly what the script does:
- Asks for confirmation
- Stops MySQL
- Starts MySQL without grant tables
- Waits a couple of seconds for MySQL to start
- Generates new password of random length
- Changes root password in MySQL
- Stops insecure MySQL
- Starts the MySQL service again
- Exits and prints your new password
- Save the script locally on the MySQL host
- Run the script as root or using sudo
$ sudo bash mysql_pwd_reset.sh
- Save the new password
- Delete the script, just in case
