ruby – Redis-RB开箱即用,在本地抛出ECONNREFUSED错误

概述我在我的Gemfile中添加了gem’redis’. Ran捆绑安装.重新启动本地服务器,然后仅在我的控制台中运行hello world示例以获取错误.知道什么是错的吗？ [kudo (develop)]$rails consoleLoading development environment (Rails 3.2.3)1.9.3p125 :001 > redis = Redis.new=> 我在我的Gemfile中添加了gem’redis’. Ran捆绑安装.重新启动本地服务器,然后仅在我的控制台中运行hello world示例以获取错误.知道什么是错的吗？

解决方法 结束非常简单.

要安装redis(服务器)我跑(在终端)：

brew install redis

然后在一个单独的终端窗口中,我启动了服务器：

redis-server

现在我都安排好了.我的redis.set命令现在在rails控制台中运行正常.

这是一个很好的资源,我发现更深入地了解它：http://jimneath.org/2011/03/24/using-redis-with-ruby-on-rails.html
