Some installation tutorials on the Internet are cumbersome. In fact, you only need two RPM packages to complete the deployment of one instance in a few minutes.
PreparationDownload Erlang package: http://www.rabbitmq.com/releases/erlang/Download
Installing RABBITMQ under 1.Windows requires the following steps(1): Download Erlang because the RABBITMQ server code is written using Erlang in the Concurrency language: http://www.erlang.org/downloads, Double-click the. exe file to install it, create an environment variable named Erlang_home after installation, its value points to the installation directory for ERLANG, add%erlang_home%\bin to path, and fi
Background:Various Application Systems in today's society, such as business, social networking, search, and browsing, constantly produce information like information factories. In The Big Data era, we are faced with the following challenges:
How to collect this huge information
How to analyze it
How to implement the above two points in a timely manner
These challenges form a business demand model, that is, information about producer production (produce) and consumer consumption (consume) (pr
I. What is Message Queuing?A message is the data that is transferred between apps. Messages can be very simple, such as containing only text strings, or they can be more complex and may contain embedded objects.Message Queuing is a way of communicating between applications, which can be returned immediately after a message is sent, and the message system ensures reliable delivery of the message. The message publisher simply publishes the message into MQ without having to take care of who gets it

the Kafka cluster configuration typically has three methods , namely
(1) Single node–single broker cluster;
(2) Single node–multiple broker cluster;(3) Multiple node–multiple broker cluster.
The first two methods of the official network configuration process ((1) (2) To configure the party Judges Network Tutorial), the following will briefly introduce the first two methods, the main introduction to the last method.
