Change DB setting

How to change the DB setting as shown below in the source code when I start it in a standalone model with metabase.core?

export MB_DB_TYPE=postgres
export MB_DB_DBNAME=metabase
export MB_DB_PORT=5432
export MB_DB_USER=<username>
export MB_DB_PASS=<password>
export MB_DB_HOST=localhost

I have changed metabase.config, but It didn’t work.

:mb-db-type   
:mb-db-dbname 
:mb-db-port   
:mb-db-user   
:mb-db-host   
:mb-db-file   

Hi @caidaoliuhai
I’m not sure what you are trying to do. Could you explain in more details?

Hi, I found the problem. Thank you.

@caidaoliuhai Then it would be helpful if you write what the problem was, so others could learn from it.

Yes, I think this problem maybe is my problem.
