Ruby on Rails Postgres服务器

我正在使用Xubuntu（Xfce桌面环境）上的PostgreSQL来处理Ruby on Rails应用程序。我下载的PostgreSQL使用LinuxbrewRuby on Rails Postgres服务器

我database.yml的样子：

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

首先我得到一台服务器已经运行，并检查/tmp/pids/server.pid文件的问题，我这样做，并使用杀死进程kill -9 1420

我跑server s再次得到以下outut：

$ 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

小号Ø它看起来像它的工作原理，但一旦我真的开放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?

有谁知道如何解决这个问题？

你可以通过确保你已经运行了postgres并且在'/ config/db.yml'中有正确的设置来修复它 – max

解决...

我试图通过使用postgres -D /usr/local/pgsql/data命令启动PostgreSQL数据库。我得到一个错误，我的postgres数据不存在，并使用命令initdb PGDATA来创建它。然后我用pg_ctl -D PGDATA -l logfile start启动服务器。然后我不得不重新创建我的数据库，所以我跑了$bin\rake db:create db:migrate
