CentOS 7.2下 RabbitMQ 安装记录-白红宇

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：

明明依赖 RabbitMQ ，但在依赖项中没有列出，结果就跑不起来。

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-releaseCentOS 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；

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

只要英语不是很烂，参考官方帮助安装起来还是很简单的！
