MariaDB / MySql Warning after Netdata installation. "Access denied for user 'netdata'@'localhost' (using password: NO)" How to fix?

Question

I have configured Netdata on an Ubuntu 20.04 Server LEMP server, according to this Linuxbabe.com tutorial.

After installation, I run the following command

sudo systemctl status mariadb.service

which returns the following warning:

[Warning] Access denied for user 'netdata'@'localhost' (using password: NO)

1. What does this mean in regards to Netdata functionality?
2. Does this mean Netdata is misconfigured?
3. What can I do to fix it?

Answer 1

Have you created a netdata user in the db as per here?

Netdata needs its own db user with specific privileges.
