Passageiro + Nginx = 502 Gateway inválido

Question

Estou tentando executar um aplicativo de trilhos relativamente simples (http: // www.enkiblog.com/) e isso funciona. Os comentários e a interface administrativa só funcionam quando eu uso "script / server -e production "e conectar-se à porta 3000 (ainda em produção modo embora).

O Nginx terá isso em seu error.log:

2009/06/02 21:46:10 [error] 11536#0: *18 upstream prematurely closed

Error during failsafe response: closed stream

Alguma ideia?

p.s. debian 5.0

    

Answer 1

Acontece que foi um problema de permissões do passageiro + sqlite + nginx + unix.
Eu "resolvi" migrando para o MySQL

    

Answer 2

Você pode obter um erro 502 como este no nginx quando não tiver as permissões adequadas definidas em um banco de dados SQLite.
