RabbitMQ基础知识
一、RabbitMQ概述
RabbitMQ是一款使用Erlang语言开发的，实现AMQP(高级消息队列协议)的开源消息中间件，它具有以下特性
- 开源、性能优秀，稳定性保障
- 支持持久化，传输确认，发布确认，可靠性消息投递模式（confirm）、返回模式（return）等保证了MQ的可靠性
- 集群模式丰富，HA模式，多台RabbitMQ服务器可以组成一个集群，形成一个逻辑Broker
- 支持多种语言客户端。RabbitMQ几乎支持所有常用编程语言，包括 Java、.NET、Ruby 等
- 提供多种工作模式，工作模式有：简单模式、工作队列模式、发布订阅模式、路由模式、通配符模式
二、Linux环境下载安装RabbitMQ
1.下载Erlang和RabbitMQ
RabbitMQ是基于Erlang语言开发的，所以在先安装RabbitMQ之前先安装Erlang语言
- Erlang官网下载地址:https://packagecloud.io/rabbitmq/erlang
下载RabbitMQ
- RabbitMQ下载地址：https://packagecloud.io/rabbitmq/rabbitmq-server
2.Linux环境下安装Erlang和RabbitMQ
在Erlang的安装目录下安装Erlang
[root@bp18425116f0cojd1vnz modules]# yum install erlang-23.3.4.11-1.el7.x86_64.rpm
