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

    export APPDATABASEPASSWORD=<production_database_password>

    <production_database_password> can be found when you first ssh into your digital ocean account

Hello,

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

    psql -U postgres **
    ==> psql: FATAL: Peer authentication failed for user “postgres”
    **netstat -nlp | grep 5432
    ==> tcp 0 0 127.0.0.1:5432 0.0.0.0:* LISTEN
    4917/postgres
    unix 2 [ ACC ] STREAM LISTENING 32295 4917/postgres
    var/run/postgresql/.s.PGSQL.5432
    P.S. Changed authentication to md5 in pghba.conf. Tried to log in from shell “psql -U rails” - everything is Ok, but migration still doesnt work with old issue “fesendauth....”
