1、RabbitMQ是采用Erlang语言开发的，所以系统环境必须提供Erlang环境。

brew install rabbitmq

前提必须是mac安装了HomeBrew（软件包管理系统），以下都是基于mac版本的。

等大概十几分钟

brew services start rabbitmq;

RabbitMQWeb管理界面及授权操作

rabbitmq-plugins enable rabbitmq_management

如果出现command no find 说明环境变量没配置

配置mac的环境变量后，命令也可以使用了

2、基本命令

  #brew启动
    brew services start rabbitmq;
  #前台运行
    rabbitmq-server
  # 后台运行
    rabbitmq-server -detached
  #新建用户
    rabbitmqctl add_user 账号 密码
  #给用户分配操作权限
    rabbitmqctl set_user_tags 账号 administrator
  #修改密码
    rabbitmqctl change_password Username Newpassword 修改密码
  #删除用户
    rabbitmqctl delete_user Username 删除用户
  #查看所有用户
    rabbitmqctl list_users 查看用户清单
  #为用户设置访问权限
    rabbitmqctl set_permissions -p / 用户名 ".*" ".*" ".*" 
    rabbitmqctl set_permissions -p / root ".*" ".*" ".*"

3、我启动后出现错误

  Error: unable to perform an operation on node 'rabbit@localhost'. Please see diagnostics information and suggestions below.

Most common reasons for this are:

 * Target node is unreachable (e.g. due to hostname resolution, TCP connection or firewall issues)
 * CLI tool fails to authenticate with the server (e.g. due to CLI tool's Erlang cookie not matching that of the server)
 * Target node is not running

In addition to the diagnostics info below:

 * See the CLI, clustering and networking guides on https://rabbitmq.com/documentation.html to learn more
 * Consult server logs on node rabbit@localhost
 * If target node is configured to use long node names, don't forget to use --longnames with CLI tools

DIAGNOSTICS
===========

attempted to contact: [rabbit@localhost]

rabbit@localhost:
  * connected to epmd (port 4369) on localhost
  * epmd reports: node 'rabbit' not running at all
              no other nodes on localhost
  * suggestion: start the node

Current node details:
 * node name: 'rabbitmqcli-18-rabbit@localhost'
 * effective user's home directory: /Users/XXXX
 * Erlang cookie hash: CJKrd1APSSyKxnmLKSA77g==

因为我的 host配置错了，重新配置host，重启电脑即可（不重启电脑仍可能错误）
