tox -evenv – python mistral/cmd/launch.py –server engine –config-file path_to_config*
Running Mistral Task Executors
To run Mistral Task Executor instance perform the following command in a shell:
tox -evenv – python mistral/cmd/launch.py –server executor –config-file path_to_config

To debug using a local engine and executor without dependencies such as RabbitMQ, create etc/mistral.conf with the following settings:
[DEFAULT] rpc_backend = fake [pecan] auth_enable = False
and run in pdb, PyDev or PyCharm:
mistral/cmd/launch.py --server all --config-file etc/mistral.conf --use-debugger
To run the examples find them in mistral-extra repository (https://github.com/stackforge/mistral-extra) and follow the instructions on each example.
