How to put second django+gunicorn+nginx site under ubuntu server?

Question

ubuntu

One site got up, I'm trying to make a second one on a different port.

Created venv and activated
source crm3_env/bin/activate

Installed django and second time gunicorn
sudo pip install Django
sudo pip install gunicorn

Created gunicorn.service file for the second project
sudo nano /etc/systemd/system/gcorn_crm3.service

[Unit]
Description=crm3 daemon
Requires=gunicorn.socket
After=network.target

[Service]
User=root
WorkingDirectory=/var/www/crm3/CRM3/ #path to directory with manage.py file
ExecStart=/var/www/ crm3/crm3_env/bin/gunicorn --workers 5 --bind unix:/run/gcorn_crm3.sock CRM3.wsgi:application

[Install]
WantedBy=multi-user.target

I check gcorn_crm3.service
systemd-analyze verify gcorn_crm3.service

and an error occurs
