为什么安装它?
这得说那坑爹的Intel® Collaboration Suite for WebRTC,按照官方参考安装之后无法启动,提示:

什么是MQ?
MQ全称为Message Queue,消息队列(MQ)是一种应用程序对应用程序的通信方法。应用程序通过读写出入队列的消息(针对应用程序的数据)来通信,而无需专用连接来链接它们。消息传递指的是程序之间通过在消息中发送数据进行通信,而不是通过直接调用彼此来通信,直接调用通常是用于诸如远程过程调用的技术。排队指的是应用程序通过 队列来通信。队列的使用除去了接收和发送应用程序同时执行的要求。
查看系统版本
# cat /etc/redhat-release CentOS Linux release 7.2.1511 (Core)
安装 Erlang
yum install erlang
下载 rabbitmq
wget https://github.com/rabbitmq/rabbitmq-server/releases/download/rabbitmq_v3_6_5/rabbitmq-server-3.6.5-1.noarch.rpm可能不容易下载成功,你可以使用其它下载工具来下载;
安装 rabbitmq
# rpm --import https://www.rabbitmq.com/rabbitmq-release-signing-key.asc 以上命令执行后没有任何输出,接着执行下面的安装命令: # yum install rabbitmq-server-3.6.5-1.noarch.rpm

启动服务
rabbitmq 安装后默认不是以后台进程的方式启动的,要想使 rabbitmq 在系统启动时默认以后台进程的方式启动,请以管理员身份执行以下命令:chkconfig rabbitmq-server on
以管理员身份,启动或停止服务通常使用以下命令:
/sbin/service rabbitmq-server stop /sbin/service rabbitmq-server start你可能会遇到以下错误,点击链接查看解决方法:
Failed to start LSB: Enable AMQP service provided by RabbitMQ broker

参考官方帮助:http://www.rabbitmq.com/install-rpm.html
只要英语不是很烂,参考官方帮助安装起来还是很简单的!
