RabbitMQ is an AMQP-based messaging system used by Libretime. You should only edit these settings if you have changed the defaults since running the installer, or if you've opted to install RabbitMQ manually.
In either case, we recommend that you change at least the default password provided - you can do this by running the following line from the command line: sudo rabbitmqctl change_password <username> <newpassword> Notice: using special characters such as ! in your rabbitmq password will cause LibreTime to fail to load properly after setup. Please use alphanumerical characters only.
sudo rabbitmqctl change_password <username> <newpassword>
