Ruby on rails RubyonRails Postgres服务器

ruby-on-rails ruby postgresql

Ruby on rails RubyonRails Postgres服务器,ruby-on-rails,ruby,postgresql,Ruby On Rails,Ruby,Postgresql,我正在Xubuntu（Xfce桌面环境）上使用PostgreSQL开发RubyonRails应用程序。我使用Linuxbrew下载了postgresql My database.yml看起来像： development: adapter: postgresql encoding: unicode database: rado_dev_bouldin host: localhost port: 5432 pool: 5 username: bouldin.15

我正在Xubuntu（Xfce桌面环境）上使用PostgreSQL开发RubyonRails应用程序。我使用Linuxbrew下载了postgresql

My database.yml看起来像：

development:
  adapter:  postgresql
  encoding: unicode
  database: rado_dev_bouldin
  host: localhost
  port: 5432
  pool:     5
  username: bouldin.15

首先，我发现服务器已经在运行，为了检查

/tmp/pids/server.pid

文件，我使用

kill-91420

我再次运行服务器，得到以下结果：

$ rails s
=> Booting Thin
=> Rails 4.1.12 application starting in development on http://0.0.0.0:3000
=> Run `rails server -h` for more startup options
=> Notice: server is listening on all interfaces (0.0.0.0). Consider using 127.0.0.1 (--binding option)
=> Ctrl-C to shutdown server
Thin web server (v1.6.4 codename Gob Bluth)
Maximum connections set to 1024
Listening on 0.0.0.0:3000, CTRL+C to stop

所以它看起来很有效，但一旦我真正打开

http://localhost:3000/

我得到以下输出

Started GET "/" for 127.0.0.1 at 2017-02-03 14:07:55 -0500

PG::ConnectionBad - could not connect to server: Connection refused
    Is the server running on host "localhost" (127.0.0.1) and accepting
    TCP/IP connections on port 5432?
