CentOS 7.2下 RabbitMQ 安装记录
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：

starting app, stdout -> /home/Release-v3.1/logs/woogeen-app.stdout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。

完毕！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 startFailed to start LSB: Enable AMQP service provided by RabbitMQ broker
小结
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！
