i'm new to ruby on rails, i'm trying to run an app with postgres database, but it didn't work, i have tried to search lots of information, but i wasn't useful, Someone posted the exactly same question here Problems with rails server , I tried to use command rails new blog it created an app with sqlite3 database, it works fine, but i created app with command rails new myapp --database=postgresql after that i visit localhost page, it ocurred the exactly same error
could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket "/tmp/.s.PGSQL.5432"?
Can anyone help? it would be very much appreciated.
database.yml file information:
default: &default
adapter: postgresql
encoding: unicode
pool: 5
development:
<<: *default
database: myapp_development
test:
<<: *default
database: myapp_test
production:
<<: *default
database: myapp_production
username: myapp
password: <%= ENV['MYAPP_DATABASE_PASSWORD'] %>
Delete this file:
/usr/local/var/postgres/postmaster.pid
Original Answer: psql: could not connect to server: No such file or directory (Mac OS X)

I'm trying to run my tests for my app but I keep getting both this errors:
PG::ConnectionBad: fe_sendauth: no password supplied
PG::ConnectionBad: FATAL: sorry, too many clients already
I'be read all previous answers and it seems to be, for everybody else, either a missing password or a misconfiguration of the pg_hba.conf file.
This is how my database.yml looks like:
default: &default
adapter: postgresql
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
timeout: 5000
encoding: utf8
reconnect: true
host: localhost
username: postgres
password: <password>
development:
<<: *default
database: <dev-db>
host: <dev-host>
username: <dev-user>
password: <dev-pass>
test:
<<: *default
database: <test-db>
I already checked the pg_hba.conf config file and its configured to md5 for all entries listed.
Any clues to what might be the problem?
I'm running PostgreSQL 10, Rails 5.2.3 on Ruby 2.5.5, on a Macbook with Mojave.
Thanks in advance.
Does your postgres user actually have a password set on it? Typically there is no password for the default postgres user, so this is something you would need to have gone out of your way to do; judging by the error message, it sounds like you are using the default posgres user and have not gone out of your way to set a password in the PostgreSQL CLI.
I suggest stripping it down to a very basic default, functional config like:
postgres: &postgres
adapter: postgresql
encoding: utf8
pool: 5
development:
<<: *postgres
database: project_name_development
test:
<<: *postgres
database: project_name_test
Then incrementally add back additional configuration options one at a time, confirming that each one works before adding the next. Env vars also may not be available to database.yml depending on your project configuration and installed gems.
I am following this guide to set up a rails project with Postgres.
So far I have installed postgress and the Heroku toolbelt and done the following:
Logged in using my heroku credentials
Created a rails project using postgres rails new myapp --database=postgresq
The default database.yml file looks like this:
default: &default
adapter: postgresql
encoding: unicode
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
development:
<<: *default
database: myapp_development
test:
<<: *default
database: myapp_test
production:
<<: *default
database: myapp_production
username: myapp
password: <%= ENV['MYAPP_DATABASE_PASSWORD'] %>
created controller for homepage rails g controller welcome
Created index.html.erb and added routing. root 'welcome#index'
Then When I run the server, go to localhost:3000 and get the following error
PG::ConnectionBad (fe_sendauth: no password supplied):
Is the issue with the database.yml file or with the installation and setup of postgres?
In config/database.yml, under default: &default, add:
host: localhost
username: postgres
password: (the password you created during postgresql installation goes here)
port: 5432
Then in your terminator run rake db:create:all(don't worry if you encountered the same problem here) and then run rake db:migrate, restart your rails server and your app should now work.
P.S. I've noticed that this question was asked over a year ago and that you already figured out a solution back then. But I am putting this solution here for anyone who might face the same problem because I encountered this problem two days ago and it took me some time to figure out a solution that worked for me.
figured it out. All I had to to was open pgAdmin and login using the password I created during installation.
Add username and password to default
default: &default
adapter: postgresql
encoding: unicode
# For details on connection pooling, see Rails configuration guide
# https://guides.rubyonrails.org/configuring.html#database-pooling
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
username: postgres
password: postgres
I am using MAC OS X along with postgresql installed via Homebrew. I am developing using Rails 4.2.1 and ruby 2.2.0. The connection with postgresql server is fine but for some reason every application accesses the database "kstavrou" which is my system username, as a development database and creates the rest as defined by database.yml. That is troublesome if you have more than 1 rails app.
rake db:create output:
Konstantinoss-MacBook-Pro:ecomm-intel kstavrou$ rake db:create
kstavrou already exists
ecomm_intel_test already exists
strange thing is that if I empty database.yml still connects fine to postgresql and tries to create again the database "kstavrou" executing there all the migrations, without trying to create the test database.
rake db:create output:
Konstantinoss-MacBook-Pro:ecomm-intel kstavrou$ rake db:create
kstavrou already exists
database.yml
default: &default
adapter: postgresql
host: localhost
encoding: utf8
username: pguser
password: 123456
pool: 5
production:
<<: *default
database: ecomm_intel_prod
development:
<<: *default
database: ecomm_intel_dev
test:
<<: *default
database: ecomm_intel_test
Well the problem was that the ENV['DATABASE_URL'] was set (by some install script) so it was overwriting the database.yml configuration, as noted by steve klein, so I just removed it.
`export DATABASE_URL=postgres:///$(whoami)`
I've just opened up a Rails project that I haven't accessed for about six months.
Hitting my .dev domain or running rails c gets me the following error:
/Users/me/.rubies/ruby-2.0.0-p353/lib/ruby/gems/2.0.0/gems/activerecord-4.0.2/lib/active_record/connection_adapters/postgresql_adapter.rb:831:in `initialize': fe_sendauth: no password supplied (PG::ConnectionBad)
Looking at my database config, I can see that there is indeed no password supplied, but looking back through my Git history I can see there never has been a password supplied in development.
Testing other rails projects, I get the same error, so I am now unable to run any rails projects locally.
I haven't (deliberately) touched Postgres at all since the last time I successfully ran a project locally.
Here is an example of a rails app that was working 10 days ago and now fails with the above error:
default: &default
adapter: postgresql
encoding: unicode
pool: 5
development:
<<: *default
database: <%= ENV['APP_NAME'] %>_development
test:
<<: *default
database: <%= ENV['APP_NAME'] %>_test
production:
<<: *default
database: <%= ENV['APP_NAME'] %>_production
staging:
<<: *default
database: <%= ENV['APP_NAME'] %>_staging
[Update] This effects sites that never had an explicit user or password defined in their database.yml in the first place.
What might have changed in my setup?
There have been a few post on this issue, unfortunately none of the solutions have worked for me.
My suspicion is that my postgresql is either not running or not configured correctly.
Here is where I am at, I have a development project I have joined, they are using postgresql. Here are the step I have take to get here:
Cloned Repo
Changed name of config/ database.yml.sample -> database.yml
Changed name of config/ s3.yml.sample -> s3.yml
Ran bundle install
Ran Rake db:migrate
resulting in this error:
rake aborted!
could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/pgsql_socket/.s.PGSQL.5432"?
Here is what my files currently look like:
Database.yml
development:
adapter: postgresql
encoding: unicode
database: rentsnapper_development
pool: 5
username: user
password:
test: &test
adapter: postgresql
encoding: unicode
database: rentsnapper_test
pool: 5
username: user
password:
cucumber:
<<: *test
And My s3.yml
defaults: &defaults
access_key_id:
secret_access_key:
development:
<<: *defaults
photos_bucket: rentsnapper-photos-development

No Change, when I run rake db:migrate I get the same error
https://stackoverflow.com/a/15788389/2066855
Nothing happened
Also as a side question that may or may not be relevant linux is telling me that "ruby-1.9.3-p385 is not installed", I'm running ruby-1.9.3-p362, I suspect this is unrelated. Is this something I need to update or can I get by with my current version.
Thank you in advanced...
SOLVED: I had to fix my database.yml file. Added "host: localhost" took out user & password lines.
development:
adapter: postgresql
encoding: unicode
database: rentsnapper_development
pool: 5
host: localhost
test: &test
adapter: postgresql
encoding: unicode
database: rentsnapper_test
pool: 5
host: localhost
