Vagrant Ansible Redis - 使用不同服务器时获取127.0.0.1:6379(Errno :: ECONNREFUSED)

希望一切顺利 . 我有以下问题,并希望你可以帮助我:

我正在尝试使用vagrant和ansible部署我的rails 4应用程序 . 该应用程序的一部分是一个redis服务器 . 我已经设置并运行 192.168.33.2:6379 ,我的rails应用程序运行在 192.168.33.4 并在ubuntu nginx上运行 .

尽管我已经使用redis-rb(应用程序中的gem)设置redis并使用从YAML文件启动的app global vars在我的一个初始化程序中初始化redis对象:

$redis = Redis.new(:driver => :hiredis, :host => APP_CONFIG[:redis_host], :port => APP_CONFIG[:redis_port])

APP_CONFIG [:redis_host] = 192.168.33.2,APP_CONFIG [:redis_port] = 6379

和我的redis.conf文件中的 bind 0.0.0.0 ,当我在浏览器中访问rails应用程序时仍然收到错误 Error connecting to Redis on 127.0.0.1:6379 (Errno::ECONNREFUSED) .

当vagrant ssh-ed进入 192.168.33.4 时返回 pong ,运行 redis-cli -h 192.168.33.2 ping . 所以可以 Build 连接,我可以到达redis服务器/从 192.168.33.4 看到密钥......

在终端中运行 netstat -l 也给了我: tcp 00 *:6379 *:* LISTEN

有谁知道如何解决这个问题?

提前致谢!

Update

注意:我使用redis-rails gem并在我的应用程序中将它用于session_store和cache_store . (当不使用redis时,它有效) . 以这种方式配置:

#config/initializers/session_store.rb
MyApp::Application.config.session_store :redis_store, { 
            :host => APP_CONFIG[:redis_host],
             :port => APP_CONFIG[:redis_port],
             :db => APP_CONFIG[:redis_db],
             # :password => "mysecret",
             :namespace => "_myapp_session"}, :expires_in => 90.minutes

#config/application.rb
config.cache_store = :redis_store,"redis://192.168.33.2:6379/12/api_cache", { expires_in: 3.minutes }

    所以我能够使用单线方法解决这个问题:

    MyApp::Application.config.session_store :redis_store, servers: "redis://#{APP_CONFIG[:redis_host]}:#{APP_CONFIG[:redis_port]}/#{APP_CONFIG[:redis_db]}/myapp_session", key: '_myapp_session', :expires_in => 90.minutes
    

    请注意我之前不小心遗漏的 servers: . 另请注意 key: '_myapp_session' 重要的是添加它(并将其与redis uri中的缓存命名空间匹配?)否则在尝试连接API时会出现"Can't verify CSRF token authenticity"错误 .
