CentOS 系统部署 RabbitMQ-越努力，越幸运！-51CTO博客 | 中间件 centos7 centos 8 安装 rabbitmq
简介
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。
概念介绍
RabbitMQ 是目前流行的开源消息队列系统，用Erlang语言开发。RabbitMQ 是AMQP（高级消息队列）的标准实现。下面是它的几个关键概念：
Broker：简单来说就是消息队列服务器实体。
Exchange：消息交换机，它指定消息按什么规则，路由到哪个队列。
Queue：消息队列载体，每个消息都会被投入到一个或多个队列。
Binding：绑定，它的作用就是把exchange和queue按照路由规则绑定起来。
Routing Key：路由关键字，exchange根据这个关键字进行消息投递。
vhost：虚拟主机，一个broker里可以开设多个vhost，用作不同用户的权限分离。
producer：消息生产者，就是投递消息的程序。
consumer：消息消费者，就是接受消息的程序。
channel：消息通道，在客户端的每个连接里，可建立多个channel，每个channel代表一个会话任务。
消息队列的使用过程：
1.客户端连接消息队列服务器，打开一个Channel。
2.客户端声明一个EXchange，并设置相关属性。
3.客户端声明一个Queue，并设置相关属性。
4.客户端使用Routing Key，在EXchange 和Queue之间建立好绑定关系。
5.客户端投递消息到EXchange。
RabbitMQ的应用场景
常用的使用场景：异步处理，应用解耦，流量削锋和消息通讯四个场景
部署过程
CentOS 7系统上部署：
1.关闭防火墙及Selinux
setenforce 0
systemctl stop firewalld
2.更新epel源
yum -y install epel-release
3.下载RabbitMQ
yum -y install rabbitmq-server
4.查看已安装的插件
rabbitmq-plugins list
5.启动管理服务
rabbitmq-plugins enable rabbitmq_management
6.启动rabbitmq服务
systemctl start rabbitmq-server
7.网页登录
访问网站：http://192.168.0.103:15672
CentOS 8系统上部署：
1.关闭防火墙及Selinux
setenforce 0
systemctl stop firewalld
2.配置yum源
cd /etc/yum.repos.d/ #进入目录
vim rabbitmq-erlang.repo
[rabbitmq-erlang]
name=rabbitmq-erlang
baseurl=https://dl.bintray.com/rabbitmq-erlang/rpm/erlang/21/el/7
gpgcheck=1
gpgkey=https://dl.bintray.com/rabbitmq/Keys/rabbitmq-release-signing-key.asc
repo_gpgcheck=0
enabled=1vim rabbitmq.repo
[bintray-rabbitmq-server]
name=bintray-rabbitmq-rpm
baseurl=https://dl.bintray.com/rabbitmq/rpm/rabbitmq-server/v3.8.x/el/8/
gpgcheck=0
repo_gpgcheck=0
enabled=13.下载RabbitMQ
yum -y install rabbitmq-server
4.查看已安装的插件
rabbitmq-plugins list
5.启动管理服务
rabbitmq-plugins enable rabbitmq_management
6.启动RabbitMQ服务
systemctl start rabbitmq-server
7.网页登录
访问网站：http://192.168.0.102:15672
登录结果：使用guest证号无法登录
8.排错过程
1.查看日志
vim /var/log/rabbitmq/rabbit@centos8.log
2.上网查资料
了解原因: rabbitmq从3.3.0开始禁止使用guest/guest权限通过除localhost外的访问
解决办法：修改配置文件
vim /usr/lib/rabbitmq/lib/rabbitmq_server-3.8.2/ebin/rabbit.app
systemctl restart rabbitmq-server.service #重启服务
访问网页测试：
结果：成功访问，修改成功！
RabbitMQ相关命令
> systemctl start rabbitmq-server #开启
> systemctl stop rabbitmq-server #关闭
> systemctl status rabbitmq-server 查看状态
> systemctl restart rabbitmq-server #重启
> rabbitmqctl add_user admin password #创建用户
> #赋予权限
> rabbitmqctl set\_user\_tags admin administrator
> rabbitmqctl set_permissions -p / admin "._" "._" ".*"[root@localhost mnt1t]# yum -y install rabbitmq-server
