Restart nginx

sudo systemctl restart nginx

start myproject.service

sudo systemctl start myproject.service
sudo systemctl stop myproject.service
sudo systemctl restart myproject.service
sudo systemctl status -l myproject.service

sudo systemctl start mmserver.service
sudo systemctl stop mmserver.service
sudo systemctl restart mmserver.service
sudo systemctl status -l mmserver.service

sudo usermod -aG www-data cudmore

sudo chown -R cudmore:www-data /home/cudmore/PyMapManager/*

sudo ln -s /etc/nginx/sites-available/mmserver /etc/nginx/sites-enabled

Move mmclient/ into /var/www/html/

sudo cp -R ~/PyMapManager/mmclient/ /var/www/html/

Now I can browse

http://192.168.1.200/mmclient

Run uWSGI manually

cd /home/cudmore/mmserver
source venv/bin/activate
uwsgi --socket 0.0.0.0:5000 --protocol=http -w mywsgi:app

When i change mmserver.py, restart service

sudo systemctl restart mmserver.service
sudo systemctl status -l mmserver.service
