**RabbitMQ安装和基本操作**

# RabbitMQ介绍：[https://blog.csdn.net/ycj\_xiyang/article/details/79854379][https_blog.csdn.net_ycj_xiyang_article_details_79854379] #

**RabbitMQ集群：[https://blog.csdn.net/ycj\_xiyang/article/details/79956516][https_blog.csdn.net_ycj_xiyang_article_details_79956516]**

# 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

# **基本操作** #

## 启动RabbitMQ Server ##

service rabbitmq-server start 启动服务  
service rabbitmq-server status 查看服务状态  
service rabbitmq-server stop 停止服务  
如果启动失败  
ERROR: epmd error for host "192":badarg (unknown POSIX error)   
解决办法：  
\# vi /etc/rabbitmq/rabbitmq-env.conf   
在文件里面添加这一行：NODENAME=rabbit@localhost，保存  
(注意：rabbitmq-env.conf这个文件没有，打开之后自动创建)

[root@192 init.d]# rabbitmq-server start
