消息中间件RabbitMq简单使用

2022-06-27 23:05:38  阅读：148  来源： 互联网

标签：rabbitmq 简单 boot 消息中间件 springframework RabbitMq import org public


测试截图

 

 

 

 

 

Unacked 消息，代表消息已经投递给消费者

Ready消息，代表消息已发送，消费者未接受

 每次都是想学个东西，找了一堆教程没一个能用，等自己写好教程了，结果搜到一堆能用的教程真是头大，坑爹啊

linux服务器安装rabbitmq

yum install socat

https://github.com/rabbitmq/erlang-rpm/releases/download/v23.0.2/erlang-23.0.2-1.el7.x86_64.rpm

rpm -ivh erlang-23.0.2-1.el7.x86_64.rpm

https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.8.5/rabbitmq-server-3.8.5-1.el7.noarch.rpm

rpm -ivh rabbitmq-server-3.8.5-1.el7.noarch.rpm

启用RabbitMQ的管理插件
rabbitmq-plugins enable rabbitmq_management
5、开启RabbitMQ
systemctl start rabbitmq-server
或者
rabbitmq-server
或者后台启动

rabbitmq-server -detached
6、添加用户
rabbitmqctl add_user root 123456
7、给用户添加权限
rabbitmqctl set_permissions root -p / ".*" ".*" ".*"
给root用户在虚拟主机"/"上的配置、写、读的权限
8、给用户设置标签
rabbitmqctl set_user_tags root administrator

　页面登录使用15672端口，地址:15672

用户名  root

密码  123456
