第一步:安装RabbitMq
Rabbit安装
入门安装
后台管理
权限管理
解决用户无法远程登录
日志文件异常
插件问题（关闭后无法启动）
cd /var/lib/rabbitmq/mnesia/
#删除一下文件
rm -rf rabbit@cluster
rm -rf rabbit@cluster.pid
添加系统环境：
PATH=$PATH:/usr/lib/rabbitmq/bin
添加管理模块
# 添加web管理插件
rabbitmq-plugins enable rabbitmq_management
常见命令：
启动服务：rabbitmq-server -detached【 /usr/local/rabbitmq/sbin/rabbitmq-server -detached 】
如果rabbitmq-server 启动命令，该命令ctrl+c后会关闭服务
查看状态：rabbitmqctl status【 /usr/local/rabbitmq/sbin/rabbitmqctl status 】
关闭服务：rabbitmqctl stop【 /usr/local/rabbitmq/sbin/rabbitmqctl stop 】
列出角色：rabbitmqctl list_users
验证：
页面：http://127.0.0.1:15672/
默认账号和密码：guest/guest
第二步：在springboot中简单地使用
