This post is a quick reminder for the future that may help you too.
If you want to install the latest RabbitMQ package for your CentOS 7 you can do it in only three steps:
sudo yum install epel-release -y sudo curl -s https://packagecloud.io/install/repositories/rabbitmq/rabbitmq-server/script.rpm.sh | sudo bash sudo yum install rabbitmq-server -y
Then, as always, you can start it and enable the service:
sudo systemctl enable rabbitmq-server sudo systemctl start rabbitmq-server
Check that the service is running either with:
sudo systemctl is-active rabbitmq-server
or:
sudo systemctl status rabbitmq-server
If serving to remote hosts, a firewalld rule may be useful:
firewall-cmd --add-port=5672/tcp --zone=public --permanent firewall-cmd --reload
See ya!
