Question

我正在尝试从Rails服务器连接到Redis服务器时解决此错误，两者都在Vagrant VM中运行：

Redis::CannotConnectError: Error connecting to Redis on 127.0.0.1:6379 (Errno::ECONNREFUSED)

我认为可以使用以下内容验证Redis服务器是否正在运行：

ps aux | grep redis
redis      839  0.1  0.1  35140  1840 ?        Ssl  00:21   0:00 /usr/local/bin/redis-server *:6379 
vagrant   1220  0.0  0.0  11676   952 pts/0    R+   00:22   0:00 grep --color=auto redis

sudo netstat -tnlp

我的redis.conf中有这个：

# Accept connections on the specified port, default is 6379.
# If port 0 is specified Redis will not listen on a TCP socket.
port 6379

# If you want you can bind a single interface, if the bind option is not
# specified all the interfaces will listen for incoming connections.
#
bind 127.0.0.1

和Vagrantfile：

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.box = "ubuntu-12.04-amd64"

  # THE URL FROM WHERE THE 'CONFIG.VM.BOX' BOX WILL BE FETCHED IF IT
  # DOESN'T ALREADY EXIST ON THE USER'S SYSTEM.
  config.vm.box_url = "http://files.vagrantup.com/precise64.box"

  config.vm.network "forwarded_port", guest: 6379, host: 6379, auto_correct: true

  config.vm.provider "virtualbox" do |v|
    v.customize ["modifyvm", :id, "--memory", "1024"]
    v.customize ["modifyvm", :id, "--natdnshostresolver1", "on"]
  end

  config.vm.provision "shell", path: "init.sh"
end

我尝试跟随canonical entry，但没有取得任何进展。这可能是我忽略的显而易见的事情。有人能指出我可以尝试的其他方向吗？

编辑：完整的错误消息：

$redis = Redis.new(:host => '127.0.0.1', :port => 6379)
=> #<Redis client v3.2.2 for redis://127.0.0.1:6379/0>
$redis.set('a', 'b')
Redis::CannotConnectError: Error connecting to Redis on 127.0.0.1:6379 (Errno::ECONNREFUSED)

编辑：注释掉绑定127.0.0.1并且能够从redis框中ping，但Rails仍然没有运气：

redis-cli -h 127.0.0.1 ping
PONG

想出来，我需要为我的VM（VirtualBox）使用适配器的IP地址，以使其在我的Windows机器上运行。这很有效：

var args =  [gender, age_min, age_max, religion, country, address, zip-code, telephone];
address_bar.apply(null,args)

在Vagrant机器上连接到Redis
