Can I change rabbitmq node name?

Question

I have started to run RabbitMQ on EC2 linux.

I'm running a RabbitMQ on default settings, so my RabbitMQ node name is rabbit@{hostname} now and the hostname is default EC2 hostname, ip-{my IP address}.

I want to change the node name, if I change the directories and .pid name in mnesia/ and rabbitmq.conf file as rabbit@newhost, would it be work?

The following is what should be in the /etc/rabbitmq/rabbitmq-env.conf file (create it):

NODENAME=rabbitNodeName@myServerName

Next restart RabbitMQ:

sudo service rabbitmq-server restart

Does this preserve any persistent messages in durable queues? Or are they lost? – Stefan Moser Aug 21 '19 at 16:30
this didn't work, just tried on my 3.8.x version – Dmitry Shmakov Mar 11 '20 at 22:28

I think yes, you can configure any of this parameters using environment variables, it's described on RabbitMQ configuration page https://www.rabbitmq.com/configure.html
