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）
