error with postgresql datababse : Is the server running locally and accepting connections on Unix domain socket “/var/run/postgresql/.s.PGSQL.5432”?

Question

When I run the rake db:migrate or run the rails s command, I get the same error:

Error : could not connect to server: 
No such file or         


        

Answer 1

That means your Postgres server is not running.

Check Postgres Service status from Terminal

sudo service postgresql status

Enable Postgres Service, If not started

sudo service postgresql start

OR

sudo service postgresql restart

Now your command should work, If Postgres Service is successfully started.
