rabbitmq-server | Open source RabbitMQ : core server | Pub Sub library

Seeing the same issue myself, and have seen it in past versions.

I'd recommend using the official Team RabbitMQ packages through an additional set of repositories as they work and are more up to date: https://www.rabbitmq.com/install-rpm.html

Then remove your existing erlang and rabbitmq packages and install with fedora updates package disabled.

The client machine cannot resolve the hostname pointing to the rabbitmq server.

If the IP address isn't publicly propagated, you have to put the IP/host combination in /etc/hosts file.

You could also try to connect to the IP address instead of the hostname to clear any other network related issues.

You have explicitly named the task "add_trades_to_database"

As far as I know, the RabbitAdmin class does not offer any kind of API for creating/update users at a remote RabbitMQ server.

You can achieve what you want by creating a simple REST client that will interact with the API that allows for those actions. You can find an example of this here.

However, I would think twice before doing something like that, as there are security implications to consider (also a pointer as to why this is not allowed via the Java API).

For example, doing something like that would mean that your application will need to have admin rights to the RabbitMQ server, which is something that should be avoided.

most likely you are consuming messages without sending back the basic_ack, see for example here the ch.basic_ack

What to do:

• check the unacked messages see:
• check if you are using too many not persistent messages
• check if you are using too many not persistent queues

The error says 'cannot create /var/lib/rabbitmq/mnesia/rabbit@reana-message-broker-5f45f797ff-cs79m.pid: Permission denied'. Try providing write permission for /var/lib/rabbitmq/mnesia/ directory.

Normally Docker containers are made so that they live while their main process does. If the application exits normally or otherwise, so does the container.

It is easier to accept this behaviour than fight with it, you just need to create a config on your host machine and mount it inside the container. After that you can make changes to the local file and restart the container to make the application to read the updated configuration. To do so:

1. If you install apache-airflow[celery] on a fresh virtual environment you will see that it already installs celery for you. Thus, pip install celery is redundant.

2. You do need rabbitMQ server (the actual process). Alternatively, you can use rabbitMQ in docker.

3. Not sure about apache-airflow[rabbitmq], because I know that Celery use amqp protocol to communicate with rabbitMQ. amqp==5.0.6 package is being installed with celery's installation (which happened by pip install apache-airflow[celery]).

Your last command has a typo - it should be systemctl status rabbitmq-server (your command was missing one 'b').
