一、RabbitMQ

1.1、什么是消息队列

消息队列，即MQ，Message Queue。

1.2、AMQP和JMS

MQ是消息通信的模型，并不是具体实现。现在实现MQ的有两种主流方式：AMQP、JMS。

两者间的区别和联系：

*  JMS是定义了统一的接口，来对消息操作进行统一；AMQP是通过规定协议来统一数据交互的格式
 *  JMS限定了必须使用Java语言；AMQP只是协议，不规定实现方式，因此是跨语言的。
 *  JMS规定了两种消息模型；而AMQP的消息模型更加丰富

二、下载安装

There are two ways to install the most recent version of RabbitMQ:

*  Installing the package using Yum repositories on [Package Cloud][] or [Bintray][] (this option is highly recommended)
 *  在[Package Cloud][]或[Bintray][]上使用Yum存储库安装包(强烈推荐使用此选项)
 *  [Downloading][] the package and installing it with rpm. This option will require manual installation of all [package dependencies][].
 *  下载包并使用rpm安装它。此选项要求手动安装所有包依赖项。

2.1、RabbitMQ Erlang版本要求

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM4MjY0OTk5_size_16_color_FFFFFF_t_70 3][]

具体查看：[https://www.rabbitmq.com/which-erlang.html][https_www.rabbitmq.com_which-erlang.html]

2.2、下载合适的erlang版本

[https://packagecloud.io/rabbitmq/erlang][https_packagecloud.io_rabbitmq_erlang]

2.3、安装erlang依赖

//安装依赖
    curl -s https://packagecloud.io/install/repositories/rabbitmq/erlang/script.rpm.sh | sudo bash
    //安装erlang
    yum install erlang

2.4、安装下载的erlang

//安装rabbitmq
    yum install rabbitmq-server-3.7.17-1.el7.noarch.rpm

2.5、配置RabbitMQ

//2.1、复制配置文件
    cp /usr/share/doc/rabbitmq-server-3.7.17/rabbitmq.config.example              
    etc/rabbitmq/rabbitmq.config
    //2.2、修改配置文件
    vi /etc/rabbitmq/rabbitmq.config
    //删除loopback的前面的%%和最后的逗号

2.5、启动（关闭）RabbitMQ

您可以通过运行以下命令启动RabbitMQ服务器进程。

systemctl start rabbitmq-server   //开启服务
    systemctl enable rabbitmq-server   //开机启动
    systemctl status rabbitmq-server    //查看状态

2.6、修改防火墙规则

//开启15672端口
    firewall-cmd –zone=public –permanent –add-port=15672/tcp
    
    //重启防火墙
    firewall-cmd –reload

2.7、开启Web管理界面

//开启服务eb
    rabbitmq-plugins enable rabbitmq_management
    //重启rabbitMQ
    systemctl restart rabbitmq-server

2.8、访问管理界面

三、安装碰到的问题

3.1、登陆失败

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM4MjY0OTk5_size_16_color_FFFFFF_t_70 4][]

登录遇到问题：User can only log in via localhost

//修改rabbit.app
    vi /usr/lib/rabbitmq/lib/rabbitmq_server-3.7.17/ebin/rabbit.app 
    
    将：{loopback_users, [<<”guest”>>]}，
    改为：{loopback_users, []}，
    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

重启服务即可正常登录：

systemctl restart rabbitmq-server.service
