Installing the library

Create a Python virtual environment:

mkdir fedora-messaging-tutorial
cd fedora-messaging-tutorial
mkvirtualenv -p python3 -a `pwd` fedora-messaging-tutorial
workon fedora-messaging-tutorial

Install the library and its dependencies:

git clone
cd fedora-messaging
python develop

Make sure it is available and working:

fedora-messaging --help

Setting up RabbitMQ

Install RabbitMQ and start it:

dnf install rabbitmq-server
systemctl start rabbitmq-server

RabbitMQ has a web admin interface that you can access at: http://localhost:15672/. The username is guest and the password is guest. This interface lets you change the configuration, send messages and read the messages in the queues. Keep it open in a browser tab, we’ll need it later.


An example of the library configuration file is provided in the config.toml.example file. Copy that file to /etc/fedora-messaging/config.toml to make it available system-wide. Alternatively, you can copy it to config.toml anywhere and set the FEDORA_MESSAGING_CONF environement variable to that file’s path.

Refer to the documentation for a complete description of the configuration options.

Comment out the callback and bindings options, and all the [exchanges.custom_exchange] and [queues.my_queue] sections.

In the [client_properties] section, change the app value to Fedora Messaging tutorial.
