I'm using yaml. It has a line says : daemonize : /var/www/apps/myapp.log
If uwsgi -y vassals/myappconfig.yaml, the website runs in background. I can do other things in terminal, even logout. This is the effect I'm expecting.
If uwsgi --emperor vassals, the website can run, but it stuck up in terminal. I must use ctrl + c to end it to return to terminal. Then the website is down. That's not what I'm expecting.
I don't want to use things like nohup. If uwsgi --emperor is not the right solution, I'd rather to load websites one by one, all run daemonized.
you can pass --daemonize <logfile> to the emperor too
