mount = /=wsgi:application
chdir = /home/wagtail/mysite/
wsgi-file = mysite/wsgi.py
socket = /home/wagtail/mysite/mysite/%n.socket

logto = /home/wagtail/mysite/mysite/%n.log
workers = 4
uid = wagtail
gid = wagtail
limit-as = 512

nano /etc/systemd/system/uwsgi.service

Add the following code lines:
