Database connection error on Rails application with postgresql database

Good day! Could You help me with issue after installing RoR image with postgresql - generate model and after it make migration: rake db:migrate RAILS_ENV=production. Get a mistake - “PG:ConnectionBad: fe_sendauth: no password supplied”. What can I do? (export APP_DATABASE_PASSWORD=**** helps only if there is no restart).

I was having the same error, and for me the environment variables wan’t set. It was just a matter of executing “. /etc/default/unicorn” as seem here to properly setup the variables.

After that all started working again.

Can you verify if the database works outside of the Rails environment?

What happens when you run these commands in console/terminal?

Run a login test:

psql -U postgres

Run a port test:

netstat -nlp | grep 5432
