Installing rabbitmq on alicloud server

1. Install Erlang

yum install erlang

Download the RPM package

 wget http://www.rabbitmq.com/releases/rabbitmq-server/v3.6.15/rabbitmq-server-3.6.15-1.el7.noarch.rpm

3. Install after downloading

yum install rabbitmq-server-3.6.15-1.el7.noarch.rpm

4. Restart the service after installation

service rabbitmq-server start

5. Check service status

service rabbitmq-server status

6. Install the plug-in

/sbin/rabbitmq-plugins enable rabbitmq_management 

Restart the service

service rabbitmq-server restart
