Hello,
I created new rails application using one-click installation. It gave me two users: root and rails.
When I try to run migrations on my rails user, it says:
RAILS_ENV=production rails db:migrate
=>rake aborted!
PG::ConnectionBad: could not connect to server: Connection refused
Is the server running on host "localhost" (127.0.0.1) and accepting
TCP/IP connections on port 5432?
I tried to login to root, and run: sudo systemctl postgresql start but even if there is no errors returned, calling psql still returns problem with connectint to the server:
psql
psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
I did not change any config yet, it’s raw installation. The weird thing is that the application actually works - so it is somehow connected to the postgres database.
How can I solve this problem?

Accepted Answer
When I deployed the Ruby on Rails one click application these were all of the commands I used to get to the psql command line:
root@ruby-rails:~# su - rails
rails@ruby-rails:~$ psql
After switching to the rails user and ran the psql command I could access the psql cli. If that’s not working for you it may be a corrupted install. :/
