PostgreSQL sunucusuna bağlanılamadı

Güncelleme demlemek ve demlemek Yükseltme yaptım sonra benim isim biraz sorun var. PostgreSQL Kaldır ve tekrar yüklemeyi denedim, ama işe yaramadı.

Bu bir hata iletisidir.(Ben de komisyon db yapmaya çalıştığımda bu hata iletisi:göç) var

$ psql
psql: 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"?

Bunu nasıl çözebilirim?

Mac versiyon: Dağ aslanı.

homebrew versiyon: 0.9.3

PostgreSQL sürümü: numarasını (PostgreSQL) 9.2.1

Ve bu ne yaptım.

$ psql, kullandığımda howbrew ben yeniden sonra, herhangi bir hata mesajı görünmüyor.

Ama benim raylar app rake db:migrate işletiyorum gösterir:

Couldn't create database for {"adapter"=>"postgresql", "encoding"=>"unicode", "database"=>"riy_development", "pool"=>5, "username"=>nil, "password"=>nil}

Sonunda çözümü buldum.

$ sudo mkdir /var/pgsql_socket/
$ sudo ln -s /private/tmp/.s.PGSQL.5432 /var/pgsql_socket/

Bu çözüm biraz zor, ama işe yarıyor. Herkes daha iyi bir çözüm vardır umarım

Benzer bir sorunu vardı; pıd dosyası başlatılmasını engelleyen isim oldu. Bunu düzeltmek için:

rm /usr/local/var/postgres/postmaster.pid

ve daha sonra tüm iyi.
