消息中间件RabbitMq简单使用

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

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
  
1.启用RabbitMQ的管理插件
rabbitmq-plugins enable rabbitmq_management
 
2.开启RabbitMQ
后台启动
systemctl start rabbitmq-server
非后台启动
rabbitmq-server
 
3.停止rabbitmq
systemctl stop rabbitmq-server
 
4.添加用户
rabbitmqctl add_user root 123456
 
5.给用户添加权限
给root用户在虚拟主机"/"上的配置、写、读的权限
rabbitmqctl set_permissions root -p / ".*" ".*" ".*"
 
6.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
