tar -xf rabbitmq-server-generic-unix-3.12.2.tar.xz && rm -f rabbitmq-server-generic-unix-3.12.2.tar.xz
mv rabbitmq_server-3.12.2 /opt/rabbitmq

# compile 
# no need

# postinstallation
cd /opt/rabbitmq
export PATH=$PATH:/usr/local/erlang/bin:/opt/rabbitmq/sbin
# echo "export PATH=$PATH:/usr/local/erlang/bin:/opt/rabbitmq/sbin" >> ~/.bashrc && source ~/.bashrc

# startup and init

rabbitmqctl add_user admin 123456
rabbitmqctl set_permissions -p "/" admin ".*" ".*" ".*"
rabbitmqctl set_user_tags admin administrator
rabbitmqctl stop && rabbitmq-server -detached

### option: cluster mode

Troubleshooting

# problem 1

Deploy By Container

Run On Docker

# pull image
docker pull rabbitmq:3

# run
docker run --rm --name rabbitmq -d rabbitmq:3
# run with management
docker run --rm --name -it rabbitmq -p 5672:5672 -p 15672:15672 rabbitmq:3.12-management

# test
docker exec -it rabbitmq sh

Run On Kubernetes

# add and update repo
helm repo add bitnami https://charts.bitnami.com/bitnami
helm update

# get charts package
helm pull bitnami/rabbitmq --untar
cd rabbitmq

# configure and run
vim values.yaml
...
helm -n middleware install rabbitmq .
