Alcuni giorni fa, sono stato in grado di installare Postgresql e creare/migrare i miei database da SQLite (in preparazione per la distribuzione dell'app Rails 4) ... o almeno così pensavo.Postgres non si collegherà al server nell'app Ruby on Rails utilizzando c9.io
Ho riavviato il mio server, ma quando provo ad accedere al mio app, ottengo questo errore:
PG::ConnectionBad
could not connect to server: Connection refused
Is the server running locally and accepting connections on Unix domain socket
"/var/run/postgresql/.s.PGSQL.5432"?
Ho visto diverse risposte alle domande simili su SO, ma tutti coinvolgono i Mac. Poiché sto utilizzando l'IDE di Cloud 9, ho pensato che potrebbero esserci delle differenze (ad esempio, le citazioni di localhost non sono probabilmente rilevanti, perché non è così che accedo all'app attualmente su c9.io.)
Secondo alle risposte sulle altre questioni, ho provato questo nel mio terminale:
sudo ps auxw | grep post
che mi ha dato:
ubuntu 2527 0.0 0.0 10552 888 pts/5 S+ 15:21 0:00 grep --color=auto post
poi ho provato:
sudo find/-name .s.PGSQL.5432 -ls
ed ho ottenuto:
5286 0 lrwxrwxrwx 1 root root 26 May 11 15:13 /var/pgsql_socket/.s.PGSQL.5432 -> /private/tmp/.s.PGSQL.5432
5183 0 srwxrwxrwx 1 postgres postgres 0 May 10 22:18 /run/postgresql/.s.PGSQL.5432
[email protected]_registration:~/workspace (master|MERGING) $ psql
psql: could not connect to server: Connection refused
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
Ecco la traccia completa del mio server:

non sembra che Postgresql sia in esecuzione. Forse non è impostato per l'avvio automatico. Prova 'sudo service postgresql start' e controlla se ritorna. se funziona, basta "sudo update-rc.d postgresql defaults" per farlo partire all'avvio se si desidera – Doon
@Doon si scopre che postgresql non è stato avviato e l'app ora carica, quindi grazie! tuttavia, quando inserisco "sudo update-rc.d postgresql defaults" dopo averlo avviato, dice che i collegamenti di avvio/arresto del sistema per /etc/init.d/postgresql esistono già. Dubito che ciò significa che l'avvio automatico è già attivo, perché ovviamente non è stato avviato quando ho avviato il server. –
Sto avendo lo stesso errore. ma il mio postgresql è già in esecuzione: ** sudo servizio postgresql stato ** '9.4/main (porta 5432): online' – dima
