问题
I just installed RabbitMQ on an AWS EC2-Instance (CentOS) using the following,
sudo yum install erlang
sudo yum install rabbitmq-server
I was then able to successfully turn it on using,
sudo chkconfig rabbitmq-server on
sudo /sbin/service rabbitmq-server start
...and
sudo /sbin/service rabbitmq-server stop
sudo sudo rabbitmq-server run in foreground;
But now I'm trying to modify the /usr/local/etc/rabbitmq/rabbitmq-env.conf file so I can change the NODE_IP_ADDRESS but the file is no where to be found.
No rabbitmq folder under,
[ec2-user@ip-0-0-0-0 sbin]$ ls /usr/local/etc
[ec2-user@ip-0-0-0-0 sbin]$
There's a rabbitmq folder under /etc but there's nothing in it,
[ec2-user@ip-0-0-0-0 rabbitmq]$ pwd
/etc/rabbitmq
[ec2-user@ip-0-0-0-0 rabbitmq]$ ls
[ec2-user@ip-0-0-0-0 rabbitmq]$
And the only thing in my environment variables for rabbitmq is this
[ec2-user@ip-0-0-0-0 rabbitmq]$ printenv | grep rabbit
PWD=/etc/rabbitmq
I was able to go to the location of the rabbitmq logs and find this information,
root@ip-0-0-0-0
[/var/log/rabbitmq]# pwd
/var/log/rabbitmq
root@ip-0-0-0-0
[/var/log/rabbitmq]# ls -al

And last but not least apparently the logs say there isn't a config file,
[/var/log/rabbitmq]# cat rabbit\@ip-0-0-0-0.log | grep config
config file(s) : (none)
config file(s) : (none)
RabbitMQ Version: {rabbit,"RabbitMQ","3.1.5"}
Does anyone know what's going on here? I'm surprised I didn't see any errors when I started the rabbitmq-server. Do I just create the config files myself?
UPDATE:
I was setting up a cluster environment for my Apache Airflow and so I was configuring it with the CeleryExecutor and setting up the Queue to be RabbitMQ. Turns out I'm running my EC2-Instance with Amazon Linux 1 which doesn't include systemd so I wasn't able to get RabbitMQ properly installed. Had I made my server using Amazon Linux 2 or Ubuntu, or any other Linux that doesn't suck I could have potentially gotten further in installing RabbitMQ and getting it to work with Airflow. So I went on to using AWS SQS for my queue and then I ran into this error. So by now I've wasted over two and a half days trying to just get a queue to work with Celery and Airflow and I read this article which says that Airbnb (the creators of Airflow) are using Celery with Redis as their Queue. So I tried it out and it literally took me three minutes to do and it's working flawlessly.... All I did was download Redis using sudo yum install redis then bam I had Redis installed. I started Redis using redis-server. Then I changed my airflow.cfg broker_url field to broker_url = redis://, ran airflow initdb, restarted the scheduler airflow scheduler, then started a worker airflow worker and BAM my DAGs started running using the Redis queue and CeleryExecutor. HALLELUJAH just use Redis as your queue....

The RabbitMQ team monitors the rabbitmq-users mailing list and only sometimes answers questions on StackOverflow.
You should be using the latest version of RabbitMQ (3.7.5) and Erlang 19.3 or later. Version 3.1.5 is very, very, very old. Please see this document for instructions on how to install a recent RMQ on an rpm-based distro.
After that, you will create rabbitmq-env.conf yourself.
