ruby-on-rails - 从 Ruby 到 Azure 的 Redis::TimeoutError

Question

我正在尝试从 Ruby on Rails 访问 Azure Redis 缓存服务。我安装了 gem 'redis' (3.1.0)。我想使用 SSL 来完成此任务。

这是我在 config/initializers/redis.rb

中的代码

$redis = Redis.new(:host => '[APP_NAME].redis.cache.windows.net', :port => 6380, :db => 10)
$redis.auth("[ACCESS_TOKEN]")

然后，我运行 rails c 并在 auth 调用中 100% 收到“连接超时”消息。我在 .NET 中工作，所以我不确定为什么它在这里失败。

这有效:

在Gemfile中:

gem 'redis', github: 'RedisLabs/redis-rb', branch: 'ssl'

在config/initializers/redis.rb

$redis = Redis.new(:host => '[APP_NAME].redis.cache.windows.net', :port => 6380, :db => 10, :password => "[ACCESS_TOKEN]", :use_ssl => true)
