4-rabbitmq's Introduction

利用RabbitMQ消息队列架设实时机器学习服务

本章我们将会学习RabbitMQ在实战中的用法,并且应用RabbitMQ搭建消息队列, 整合实时机器学习应用中的各种服务。

下载本章实例程序

下载本章实例程序和数据,只需执行下面操作:

git clone https://github.com/real-time-machine-learning/4-rabbitmq

安装配置软件环境

本章会运用到Docker作为集群配置方法,其余软件均通过Docker配置安装。

  • 如需要复习Docker安装配置方法,看这里
  • 如需复习Scikit Learn基本操作,看这里
  • 如需复习Pandas基本操作,看这里

利用RabbitMQ搭建股价预测集群

完成之后我们的集群的构架如下图:

案例构架

运行本章节实例

只需在命令行本章节代码目录中运行以下代码,即可启动该集群。

docker-compose up 

可能遇见的问题

本案例使用了Elasticsearch 5.0 的Docker镜像,在有些电脑上(如笔者的), 需要对系统环境变量进行少许调整,才能正常运行。需要运行以下命令

sudo sysctl -w vm.max_map_count=262144
