rabbit-mq 本地环境搭建记录

以下五步转自：https://blog.csdn.net/shushugood/article/details/81076917 部分内容稍有修改。
一、安装RabbitMQ需要先安装Erlang语言开发包 下载地址https://www.erlang.org/downloads本文下载的是22.2版本。下载安装完成后（例如安装在E:\erl10.6下） 需要添加环境变量 ERLANG_HOME=E:\erl10.6 之后在Path中添加 %ERLANG_HOME%\bin
二、安装RabbitMQ Server 下载地址https://www.rabbitmq.com/download.html本文下载的是3.8.2版本。下载完成后（例如安装在E:\RabbitMQ Server\rabbitmq_server-3.8.2）添加环境变量RABBITMQ_SERVER=E:\RabbitMQ Server\rabbitmq_server-3.8.2 在path中添加 %RABBITMQ_SERVER%\sbin
三、以管理员身份运行cmd.exe，进入目录 E:\RabbitMQ Server\rabbitmq_server-3.8.2\sbin（RabbitMQ Server安装目录），运行cmd命令：rabbitmq-plugins.bat enable rabbitmq_management
四、以管理员身份运行cmd.exe，运行命令：net stop RabbitMQ && net start RabbitMQ。启动RabbitMQ Server，
五、在浏览器输入地址：http://localhost:15672，输入默认账号：guest 密码：guest。

补充：
在搭建完环境之后启动已有java项目连接mq，配置文件

rabbitmq:
    host: localhost
    port: 5672
    username: guest
    password: guest
    virtual-host: center

发现报错

将配置文件中的virtual-host改为 / 即可成功启动 （rabbit web管理界面上会显示vhost名字，在没有自定义vhost时，默认的vhost是 ‘/’ ）

rabbitmq:
    host: localhost
    port: 5672
    username: guest
    password: guest
    virtual-host: /
