Description:
Hey guys.

I just installed the AWS AMI bitnami-mariadb-10.4.12-0-r01-linux-debian-9-x86_64-hvm-ebs-nami - ami-06f7f724f2f839acf (my first AMI all times) and it seems to be OK, I managed to access it through Putty and login into the database.

However, I don't want to keep the original passwords for users bitnami (Debian) and root (MariaDB) for security reasons. Thus, I have tried a lot of commands to change both, failed in all attempts. My knowledge of Linux and MariaDB is superficial and I really need guidance here.

So, please, tell me how should I proceed to change these passwords.

Best regards,
Renato

Hi @renatospaka,

We do not configure a password for the bitnami system's user so there is nothing to change. You can access the instance using a SSH Key, not a password.

Did you take a look at our documentation?

https://docs.bitnami.com/aws/infrastructure/mariadb/administration/change-reset-password/

Thanks

Hey @jota, thanks for your suggestions.

Could you confirm a piece of information regarding this: "We do not configure a password for the bitnami system's user so there is nothing to change. You can access the instance using a SSH Key, not a password."
The bitnami user has no password or you are not going to provide me the password so I can change it? It is really important for me to let no user with default or blank password.

The 2nd point: "Did you take a look at our documentation? https://docs.bitnami.com/aws/infrastructure/mariadb/administration/change-reset-password/"
Yes, I did and followed the instructions. Nevertheless, the password didn't change. There is a screenshot attached you may check the commands and responses.

Best regards,
Renato

Hi @renatospaka,

The bitnami user has no password.

I just followed the guide and could change the password without problems

bitnami@ip-172-31-1-168:~$ /opt/bitnami/mariadb/bin/mysqladmin -pMY_OLD_PASSWORD -u root password MY_NEW_PASSWORD
bitnami@ip-172-31-1-168:~$ mysql -u root -pMY_NEW_PASSWORD

MariaDB [(none)]> exit
Bye

Did you try to change the MariaDB's password lately? It seems it can't connect to the database and I don't know if you changed something in the configuration

Never mind jota, I just killed the instance and created a new RDS for
MariaDB. It seems to be easier.

Thanks for your support.

Best regards.
