Update the cache. Accept the required keys from packetcloud.io and github.com.

dnf makecache

Execute on all nodes.

Install the RabbitMQ-Server with all dependencies.

dnf install rabbitmq-server

Start the RabbitMQ-Server on system startup.

systemctl enable rabbitmq-server.service

Execute on mb1.

All nodes in the cluster must have the same erlang cookie. We copy it fro mb1 to the other nodes.

scp /var/lib/rabbitmq/.erlang.cookie mb2:/var/lib/rabbitmq/.erlang.cookie
scp /var/lib/rabbitmq/.erlang.cookie mb3:/var/lib/rabbitmq/.erlang.cookie

vim /etc/rabbitmq/rabbitmq.conf

scp /etc/rabbitmq/rabbitmq.conf mb2:/etc/rabbitmq/
scp /etc/rabbitmq/rabbitmq.conf mb3:/etc/rabbitmq/
