RabbitMQ安装和基本操作
RabbitMQ介绍：https://blog.csdn.net/ycj_xiyang/article/details/79854379
概要
RabbitMQ是一款开源的消息代理服务器，用来进行信息路由。
MQ可以是架构变得松耦合，从而更有弹性，跟灵活，是SOA架构不可或缺的组成部分，担当服务总线或信息总线的角色。
安装
RabbitMQ是由Erlang语言构建的，所以要先安装Erlang，安装Erlang最方便的是使用epel库。
Epel仓库
安装epel仓库
在CentOS6和CentOS7都可以执行下面的命令安装epel仓库
yum -y install epel-release
这条命令的好处是可以自动安装不同版本的epel，比如在CentOS6上面安装的是epel6，在CentOS7上面安装的epel7。
可以在etc/yum.repos.d中手动配置阿里的epel源。
注意：如果出现
Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os error was
14: PYCURL ERROR 6 - "Couldn't resolve host 'mirrorlist.centos.org'"
Error: Cannot find a valid baseurl for repo: base
这种错误，是因为没有配置/etc/resolv.conf。
解决方法：编辑resolv.conf文件，添加：
nameserver 8.8.8.8移除epel仓库
yum -y remove epel-release
查看仓库信息
yum repolist
安装erlang
yum -y install erlang[root@192 yum.repos.d]# yum -y install erlang
Loaded plugins: fastestmirror

* base: mirrors.sohu.com
* epel: mirrors.sohu.com
* extras: mirrors.sohu.com
