I am running nginx and uWSGI. I added this to /etc/systemd/system/uwsgi.service:

ExecStart=/usr/bin/scl enable python27 bash; /usr/bin/uwsgi --emperor
/etc/uwsgi/sites

But it did not start:

   Loaded: loaded (/etc/systemd/system/uwsgi.service; enabled; vendor
preset: disabled)
   Active: failed (Result: start-limit) since Mon 2017-12-11 17:20:36
EST; 6s ago
  Process: 24492 ExecStart=/usr/bin/scl enable python27 bash;
/usr/bin/uwsgi --emperor /etc/uwsgi/sites (code=exited,
status=1/FAILURE)
