Passwords
When we accessed MySQL earlier in this tutorial, we needed to use a password manually. Passwords help to secure our database and are essential for security. Over time it is a good practice to change the password frequently. Here we will go through setting and changing the password for the admin user.
Retrieve the root password
As previously mentioned, the root password can be retrieved by running the get-password action on the Charmed MySQL application:
juju run mysql/leader get-password
Running the command should output:
...
password: yWJjs2HccOmqFMshyRcwWnjF
username: root
Rotate the root password
You can change the root password to a new random password by entering:
juju run mysql/leader set-password
Running the command should output:
Running operation 12 with 1 task
- task 13 on unit-mysql-1
Waiting for task 13...
status: completed
Please notice the status: completed above which means the password has been successfully updated. To be sure, please call get-password once again:
juju run mysql/leader get-password
Running the command should output:
password: 5wEFCr67qMAmsbi0dcLGwvN9
username: root
The root password should be different from the previous password.
Set the root password
You can change the root password to a specific password by entering:
juju run mysql/leader set-password password=my-password && \
juju run mysql/leader get-password
Running the command should output:
Running operation 18 with 1 task
- task 19 on unit-mysql-1
Waiting for task 19...
Running operation 20 with 1 task
- task 21 on unit-mysql-1
Waiting for task 21...
password: my-password
username: root
The root password should match whatever you passed in when you entered the command.
