如何在vagranted虚拟机上访问postgresql？

Question

我使用postgresql通过Vagrant虚拟机制作,并希望将其用作我的rails应用程序数据库.

我使用类似的Vagrantfile:

Vagrant.configure("2") do |config|
  config.vm.network :private_network, ip: "192.168.33.18"
  config.vm.provision :chef_solo do |chef|
    # I take cookbook from https://github.com/opscode-cookbooks/postgresql
    chef.add_recipe "postgresql::server"
    chef.json = {
      postgresql: {
        config: {
          ssl: false,
          listen_addresses: '*'
        },
        password: {
          postgres: 'postgres'
        }
      }
    }
  end
end

接下来,我vagrant up希望接下来database.yml会有效:

development:
  database: app_development
  adapter: postgresql
  host: '192.168.33.18'
  username: root

但这不会发生.. Rake任务失败并出现错误:

could not connect to server: Connection refused
    Is the server running on host "192.168.33.18" and accepting
    TCP/IP connections on port 5432?

我看到端口实际上没有打开

$ nmap -p 5432 192.168.33.18

Starting Nmap 6.25 ( http://nmap.org ) at 2013-05-07 22:05 FET
Nmap scan report for 192.168.33.18
Host is up (0.00047s latency).
PORT     STATE  SERVICE
5432/tcp closed postgresql

我可以在vm上看到一些postgres进程,并且没有任何错误的vagrant输出,所以我相信postgres正常工作.

如何在我的rails应用程序中设置Vagrant在虚拟机上使用db？

更新我的pg_hba.conf

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     peer

###########
# Other authentication configurations taken from chef node defaults:
###########

local   all             all                                     trust

host    all             all             0.0.0.0/0               md5

我向所有读者道歉,但问题在于我的注意力不集中.虽然我指向listen_addresses: '*'配置,然后我意外重置此配置,因此在最终配置中采用默认listen_addresses: 'localhost'值.修复后,此端口被打开.
