Я не могу запустить uwsgi как обычный пользователь

Я хочу запустить сервер uwsgi как www пользователь, но если я напишу:

uwsgi --socket $SOCKET --chmod-socket 666 --pidfile $PIDFILE --daemonize $LOGFILE --chdir $CHDIR --pp $PYTHONPATH --module main --post-buffering 8192 --workers 1 --threads 10 --uid www --gid www

Произошла ошибка создания сокета:
