1. Install erlang
rpm -Uvh http://download.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-8.noarch.rpm yum install erlang
2. Install rabbitmq-server directly with yum, generally no problem
yum install rabbitmq-server
3. Start the server
service rabbitmq-server start
service rabbitmq-server status
service rabbitmq-server stop
After opening, see that port 5672 is started
4. Development port and management functions
firewall-cmd --zone=public --add-port=5672/tcp --permanent firewall-cmd --reload
5. Open management function
rabbitmq-plugins enable rabbitmq_management
After that, you also need to open port 15672. If you use Alibaba Cloud server in steps 4 and 5, you need to set an open port on Alibaba Cloud.
