rake db:create で ActiveRecord::NoDatabaseError

Posted at

Rails 環境の構築中に、rake db:create で以下のエラーが発生。

ActiveRecord::NoDatabaseError: 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"?

ググると .pid ファイル消すといいとかって記事が色々ヒットするけど、全然なおらない。

2h くらい引っかかっていた時、さっきまで動いてた別のブランチで、同じ手順で構築し直して rake db:create するとなぜか動く。

作業していたファイルの差分を見ると・・・、

 default: &default
   adapter: postgresql
   encoding: unicode
-  host: db
-  username: postgres
-  password: password
-  pool: 5

そりゃ動かないよね。凡ミス。

おしまい。
