這是我的錯誤。postgresql無法連接錯誤。
PG::Error - could not connect to server: Connection refused
Is the server running on host "localhost" (::1) and accepting
TCP/IP connections on port 5432?
could not connect to server: Connection refused
Is the server running on host "localhost" (127.0.0.1) and accepting

我使用自制軟件到/ usr/local/bin目錄/ PSQL 爲了得到它認識到這個版本,我不得不加入到我的bash文件安裝PostgreSQL的。
export PATH="/usr/local/bin:/usr/local/sbin:~/bin:$PATH"
當我cd到我的Rails應用程序,並運行命令
rails s
它開始了下面
=> Booting Thin
=> Rails 4.0.0.beta1 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
>> Thin web server (v1.5.0 codename Knife)
>> Maximum connections set to 1024
>> Listening on 0.0.0.0:3000, CTRL+C to stop
然後,當我嘗試查看應用程序上http://0.0.0.0:3000
我得到的以上錯誤 任何人都可能知道爲什麼會發生這種情況。
postgres不知道在哪裏可以找到服務器配置文件。 您必須指定--config-file或-D調用選項或設置PGDATA環境變量。 – user1096509 2013-03-06 00:16:00
好的發現如何使用命令行'brew info postgres'啓動它。啓動行是'pg_ctl -D/usr/local/var/postgres -l /usr/local/var/postgres/server.log start' – user1096509 2013-03-06 00:26:30
當我從mysql更改爲postgres時,在Nitrous.io上發生此錯誤。不得不重新啓動這個盒子,把我的database.yml改成'host:localhost'並把'listen address改爲'*''。 我的最終解決方案發現[這裏](https://serverfault.com/questions/461257/cant-connect-to-postgres-in-production/461265#461265) – Shadoath 2014-10-21 22:33:05
